Newly acquired 1991 Prelude B21A1

Hey everyone. My name is Joshua and i currently live in the Bethesda/Chevy Chase area of Maryland. About 10 days ago i got this Prelude with 39k miles ACTUAL.

Currently resolving a power-steering issue but i have been diligently doingmy research on the FRM-B21A1-overheating issues. This vehicle turns over nicely and idles well.

I discovered it two weeks ago, acquired at auction. The seller informed me that it had sat in a garage for nearly 14 years!!! the tires are dry-rotted all to hell but the interior is immaculate.

All that aside, i have already changed the plugs, wires & a failed salvage power steering pump. Refurbished pump arrives tomorrow.

My main reason for posting is the oil & piston rings. For the duration that this car has sat, what might be the best approach for flushing and reconditioning the lower engine?

I spent several hours today perusing the 3rd Gen topics but this situation feels a bit unique. I am not a certified mechanic but i have owned enough JUNKERS in my life to not be afraid at delving into the engine and suspension work.

Any tips would be GREATLY appreciates. With the Mileage, i want to preserve as much as possible before the inevitable piston ring rebuild.

I scoped the cylinders with my Digi snake cam and it seems that the Odom isn't lying. While the true sign of wear would be in the piston rings or an emissions test, the exhaust shows no significant oil residue as of YET.

While some say i made the wrong choice in the Model/Year, this is and has been a much desired vehicle for myself over many years. I may have bit off more than i could chew but i refuse to back away at the first sign of trouble.

Will and a Way

Re: Newly acquired 1991 Prelude B21A1

Great score!!

If you baby the motor and change oil frequently it'll give you good service.
Typically the auto version changes gears at 3000-3500 rpms and well treated engines lasted as long as 150-200k miles with little to no oil consumption...
The 5 speed model was usually leaned on pretty hard and oil changes at typical reccomended mileage intervals. Many began using oil before 100k and by 150 or so had given out.

I had a 91 5 speed with a swapped B21 from an auto that had 180k and used about a quart every 3000 miles. Original motor busted 2 rings at 145k. It's my son's now. It sits a lot. For the first 15 minutes or so it smokes due to valve issues, not rings. After that she's good.
Had another 91 auto with a B21 with 225k miles. The tranny gave out so I swapped in one from the car that donated the engine to the other one.
It leaked oil from every orifice that Honda has issues with typically and also smoked at first.
I used 4oz of stp oil treatment a few hours before changing the oil to get a nice layer of zinc in the engine. Smoking on the auto car stopped upon the first treatment.

But for an engine that sat for 14 years? Hmm...of course you have to dump the oil. If it were me..I'd dump it cold and refill, let that run in the engine until good and warm then dump that.

I was a fanatic about fresh oil in the B21. 90 days max! As soon as it took on a dark brown it was outta there. Now my car(s) did mostly short trips on any nice Sunday...one change, the oil only had 110 miles on it...didn't matter as it was day 93 or so.

I never used the wipers and only used the headlights on the auto car once. I take that back, I got caught in a freak rain in the 5 speed one day (ironically going to get new wiper blades) and appologized to the ole gal for days after.

The 91 5 speed has about 146k miles. I got it from a guy with a broken engine, swapped in another B21 and between my son and I have put about 500 miles on the car in about 2-1/2 years. Oil has been changed about 9 times...speaking of that...it's due. We'll use maxlife for it's zinc and molybdenum's extra friction fighting powers unless we stay with Defy because it has the zinc similar to the sf/sg grade oils of 1991.

Congratulations on an AWESOME find! And I have to say that you have me beat! I got my 89 with 70K original miles on it and very nice interrior, aside from some minor blemishes.

And I Agree with Byk, but I would also drop the pan and clean it out. My 89 sat for at least 2 years and there was at least an inch of sludge on the bottom of the pan. It's a lot less work than having to replace the head because the valve stuck open and the piston hit it... as mine did.

Re: Newly acquired 1991 Prelude B21A1

If I found one like that?....

Man it would cost me $75 grand...

$35000 for the climate controlled garage w/wash bay and a closed in trailer...
and $40000 for the truck that pulls it to n from car shows, 'cause that sucker would not be driven...well maybe around the block...with an escort in front and back of me.

...not to mention the cost of a ground up restoration.

#1 should be to change the timing belt. At that mileage, it's probably original, and over 3X the expected lifetime.

Re: Newly acquired 1991 Prelude B21A1

Wow! Thanks for the quick replies. I wish i could post the photos for you here but i havent seen the option.

it is an Auto (sad face) but my mechanic buddy says the conversion wouldnt be too difficult. Right now, focusing on the steering and the oil.

The Seller initially took the car as a Project but got distracted when he nabbed a 1993 supercharged Prelude. He didnt want this car sitting any more than it had so i got fortunate. He had already changed the oil so i intend to do that again.

As i said, i foraged through the 3rd Gen forum before making an account and posting. I plan to order the gaskets for the oil pan and transmission here soon. I am tentative about changing the tranny oil as i know once it is old they are 'sensitive'. I would be returning the tran-oil after i eyeball it inside and change the filter. The shift feels smooth and it idle with a bit of a tap.

From what i can tell, the power steering tensioner may be shot so i have to lookup that part as well.

As for the oil and parts, is there anything you might recommend as a parts source or brands, with the information i have provided? I want to do this the right way & the first time.

YES. Definitely doing the timing. Just with the age of it i am concerned. Preventative, measures must be taken.

Re: Newly acquired 1991 Prelude B21A1

^^ this
Waaaaaay in the back of it.

Parts geeks and napa are good sources for some oem parts.
But the 3g is fading into the halls of history. The B21 version is getting scarce for replacements of certain items used on that engine and the automatic, even more scarce.

Now don't go thinking right out the gate that auto tranny has to go. Give her a good swift kick and take off down a little travelled back road there in western maryland before you start buying parts.
Honda did all their high end versions in the automatic version for a reason. For road course type fun, that 4 speed automatic is pretty freaking amazing. And you can keep both hands on the wheel so you can really go. You'll appreciate the handling of the chassis and those 4 disc brakes more when not being distracted by changing gears.
I had way more fun in my auto version tbh. It's not for everybody. Like beer, it's an acquired taste. But once acquired it's a good alternative to liquor.
That's one man's opinion...a fan of pretty much stock versions of Honda preludes. Most want more pizazz out of them. I like 'em just fine the way Mr. Honda and his whiz kid engineers sent 'em to our shores.

Re: Newly acquired 1991 Prelude B21A1

Ah, wasn't knocking the Auto, just a preference. I uploaded a few rough shots of the Prelude.

I am holding back on naming the car, so as not to appear clingy.

Might scare away the Unicorn.....

Re: Newly acquired 1991 Prelude B21A1

I acquired an '87 Prelude back in January. I was very surprised that the tranny was still operational in a 280K mileage vehicle. After draining and changing the fluid to authentic ATF Z-1 (sold now as Idemitsu Type H), it shifts smooth as silk with no issues whatsoever. The moral of this story is that not all Honda auto trannies are bad. My '90 Acura Legend auto is still working nicely at 150K also.

As an addition to possible maintenance items, it may be wise to crack open the ECU and change the capacitors. I just did that yesterday to the Legend ECU, and my cruise now keeps the set speed again. I'm hoping my mileage improves if the engine computer works better. 25 year old caps don't always work like new. I'll post again about this "upgrade" after I work on the Prelude this weekend. I'm hoping this fix will clear up some timing issues I'm having. Surprisingly, there isn't that much info about this problem on the web with these vehicles.

Re: Newly acquired 1991 Prelude B21A1

The 3g prelude auto tranny was stellar! It was when Honda tried 'improving' on it when things went downhill.

Many times when picking from junkyard cars, they have 250k+ miles before the auto tranny failed. Some are there simply because the po couldn't get the engine to start. The cars aint worth no money on the market so they sell 'em to scrapyards for $300-500.

Re: Newly acquired 1991 Prelude B21A1

Congratulations

There is a ton of info for caring for your automobile. Definitely drop the pan, and check the oil pick up screen. If you feel a truly uncertain, seafoam it, then use a good oil. I recommend a 0-40w, cause FRMs will eventually wear out any other way.

On the classic note: you got one sexy car built when honda had a passion to amaze. Dont waste it.

Oil recommendations are like a$$holes, everyone has one. So I'll throw mine in there too. Unless you live in a very warm climate, 0w-40 may be a little viscous to use in a 3rd gen. Especially during the winter months. I would recommend either a 0w-30 or 5w-30 for most areas. Of course, one can also use higher weight oil in the summer months, and switch to a lower weight oil for the winter months.

I used to have a 91 Si with a b21a1, in which I used 5w-30 Castrol syntec synthetic blend year round. That car had 210k miles when I sold it, and it used less than 1 quart between oil changes (3500 mile oil change intervals). The b21a1 is not the terrible engine that many people make it out to be. It just doesn't hold up to abuse as well as an engine with normal cylinder sleeves. With proper maintenance they can last a long time.

Re: Newly acquired 1991 Prelude B21A1

Yeah, I completely agree Luzer. I was only taking account the fact the mileage was so lowand the FRM walls. I usually say follow the owners manual 98% of the time. The 40w oils were used in BMW 3 series through the 80's and they arent FRM.

OP, bobistheoilguy.com to make your own mind.

Re: Newly acquired 1991 Prelude B21A1

Back in Jan 2015, I also just got a 91 Prelude, with auto My mother had passed, and she gave me the Lude. I flew to WI, and drove it back to CA. It was a blast to drive back average just under 400 miles per tank

When I got back to CA. I put the Lude in the shop for repairs, I have spent more money to the sum of $3.500 on the vehicle than the cars is worth, but for me it is worth it, it only had 87k when I first picked it up in Jan, now has 93K.

I intend to keep the oil changed, keep up on all repairs, thus having to find out that parts maybe hard to get due to it being a 91, does not matter I love my Lude.

Thank You, I forgot to mention that the Lude has been in the family since 1992, she was the second owner, it was a dealer demo when she got it.

Re: Newly acquired 1991 Prelude B21A1

I resolved the power steering issue. It was just the tensioner bolt... but now i have a refurbished pump so i feel safer than with the salvaged one. There were some slight differences with the designs but i was able to Frankenstein them together to achieve my goal.

When i first got the car, i knew about the power steering problem: loud, sharp squeals that i would identify as 'barking'. The steering wheel was fighting me for every inch of turn and bouncing/rebounding from the direction of turn.

I bled the system, freeing it from the nastiest looking power steering fluid i have ever seen. I couldnt believe the previous owner didnt bleed it, also. And it is very likely they left a ton of air in the line. Again, feeling safer with the refurb over the salvage.

I am putting a few pictures of the work i have done and intend to keep updating this thread. This is not meant to be a 'Bumping' technique. Just a work in progress.

Is that ok?

I also need a hand identifying four smaller-gauge metal lines coming from the fuel tank. Pics going up shortly.

^^ Page 308 is the exact same image in the Chilton manual i purchased the other day. the 4 Lines aren't labeled... there are 6 lines in the image - largest one is the fill channel/neck for the gas cap. The 2nd largest is a Breather line, i think. But the four smaller lines are likely 1/4" and it "appears" they just reconnect to the fill channel.

I am about to open the access panels in the trunk to visually inspect that end of the connections. These 4 lines are rubber where they meet up with the tank and they are spread out at different fill levels, which leads my Mechanic buddy of 13 years to think they are Vapor Return Lines, low pressure. If so, i could just rip out all of the metal and replace them with rubber atleast at the points where they are rusted.

Also, i will try to get some better photos. Always trying to update!

Re: Newly acquired 1991 Prelude B21A1

Well, i uploaded a total of three photos relating to these 4 rusty lines. They appear to be Vapor Returns. bit of a tight space but i believe i can get them out. Thinking about just putting rubber lines back in, as they are low pressure and i know Maryland hates rust and i am currently unable to find a Supplier who has these lines OR even knows what they are exactly.

Since these are shaped lines, they must be an exact fit. Hence why i am considering rubber replacements.

Re: Newly acquired 1991 Prelude B21A1

My son and I joined a wishlist to local junkyards. You should do same. You type in say..88-91 prelude and they email you when they arrive. And they arrive often..10-20/year. We picked what's better than on our car for about a year and ended up with a lot of nice stuff.

I think Luzer has a practically whole 'nother car from doing it for years now.

^^ try these guys for shared parts.
Type in part number in the search bar to see a list of cars that shared the part.
Keep part # handy and go to 'acura parts now' as well and do same.

Also a few years ago my mechanic fixed my leaking fuel line with an okey dokey DOT approved repair line by (if memory serves) Snap On. It was at a junction where the pump on my '95 Ford Ranger leaves the tank. A critter had chewed it...twice. First time it took 6 weeks to find a fuel line. Second time he was able to do the repair with that part on the pressurized line. It's still holding after like 6 or 7 years.

Re: Newly acquired 1991 Prelude B21A1

That's excellent compression. I think mine ranged from 168 to 175 the last time I checked before I sold it. That was right after the timing belt slipped about 270 degrees. I couldn't believe no valves bent during that episode.
