Getting ready for engine install. Old engine is out and that's the easy part! Haha!

Anyways I got a few questions about the plumbing of these engines. I notice a coolant like in and out of the filter housing why does Honda do that? I know on my diesel they do that to cool the oil but on these engines it just seems odd??

I keep looking at the engine bay thinking my god I could get rid of so much crap!!! but I have to keep in mind this is my sons car and not something I am hot rodding.

Why do people leave off the timing belt covers??

Yep, that's an oil cooler. The fuel injected engines (b20a5 and b21a1 in the USDM) used an oil cooler. The carb'd engine (b20a3) did not. Not sure why they installed them, but I'm sure Honda felt they were necessary. They rarely added something like that without a good reason.

Yeah, there's a lot of clutter in there. Especially vacuum lines. It's even worse on a carbie lude. I removed the stock intake and went with a short ram intake. It really made the engine bay look a lot less cluttered. Then I replaced the stock power steering line with a SS braided line and routed it back down to the steering rack on the driver's side of the engine. This cleaned it up even more.

I think some people like to be able to see the timing belt and cam gears so they leave them off. They're just asking for trouble if you ask me. One little piece of debris and your day could get real bad in a hurry. I hope you're planning to replace the timing belt/tensioner and water pump while it's out of the car (unless that was already done). It's also a very good time to replace all of the coolant hoses you can. It's a lot easier with it sitting out of the car like that.

Yep that pic is of the new timing belt tensioner and water pump. Hoses are on my list as well.

First pic is an oil cooler.

Ppl leave the timing covers off sometimes if they have adjustable cam gears, some just wanna see the gears, others actually adjust the timing via the gears with the covers removed.

OK so I am looking at this oil cooler and I am thinking it has to come off to replace the hose that is like 2" long to the block. Does it just unthread from the center and will there be a gasket that will need replacing??

I told you I was going to be full of dumb questions..

__________________

There's 2 timing covers, and upper and lower. Taking the upper off is absolutely no problem, there's no way any debris can get that high.
Taking the lower off (which is what the crank pulley rubs on) is a bit more dangerous since debris can very easily get that low, and possibly mess with your timing belt.




Yup that one nut in the center (Its either 34 or 36mm, one of them) and it'll pull straight off.
Hey, I'd muchhhhhh prefer these TECHNICAL-newb questions, rather than "what rims should i get!??!!?!?"

I hear ya man! I am no noob to wrenching just a noob to foreign/front wheel drive cars. Is there some hose kit or do I just need to piece it together?

I admin at a Bronco site, a trailer web site and own an off road web site.

Nice collection, good luck with the build(s)!

There is no hose kit. I pieced my own kit for this last summer. I bought the hoses from Honda Parts at Honda Parts Now | Genuine OEM Honda Auto Parts. You didn't say if it's a b20a5 or a b21a1. Here is a link to the the page with the hoses for a b20a5, 5 speed transmission...
Part Detail

All but a couple of these hoses are still available from this website.

Thanks man!

Yeah it is a b20a5. Stock was the b21a1 and it is a 5 speed. Thanks for the link.

While your at it, buy an oil cooler o ring front Honda and replace the one that's behind the cooler. These are known to go bad and if it does you'll have a huge mess of oil on your driveway and in your engine bay.

Is that engine ready to go in or are you gonna have to rebuild it? aLSO IMPORTANT ARE THE FRONT AND REAR MOUNTS. tHE SIDE ONES AREN'T AS IMPORTANT. If you're gonna do the clutch, Make sure the engine is out of the car otherwise It'll take longer. Good luck.

Great collection, being old enough to appreciate those "toys" you have a great collection. Definitely liking the grand national. "hurst edition" if I may pry? Looked wild to see four seperate selectors even today. Love Jeep building, Moms old man does it up, I tinker here and there on 1990's GMs and my Goat.

Back to business:
1.Repair your bearings, HONDA is notorious for Spun Bearings. Might as well see what else is wrong with cylinder 3. I'm sure you've crossed "Ts" and dotted "Is" but mentioning/reminding is worth it's weight in gold.
2.Cam seals, another oil gusher point in the block. Somone I can't exactly remember makes a kit you put in metal seals instead of plastic, problem solved.
3.silicon vacuum hose kit: solves the hoses traveling all over the place, one color, and when I had a vacuum leak, one was burnt open from sitting against the header. Strange for me too, didn't belong there, LOL story with these cars.

All I got for now.

__________________

Cool I will do that!

Mounts and clutch are coming in today. I am not rebuilding at this point just swapping in a used engine.

Yeah I plan to replace a lot of the vacuum line but I think I going to wait until I get the engine in as I have the lines numbered.

I hate my feet had dirt on them when I moved the car and made the floor look bad for the pic.

Woohoo! Dumb question of the day!!! Anyone know the part number for a clutch set for this car? It is a D2A4 trans. I believe the parts store has gave me yet another wrong clutch. I also believe the clutch in the car may have been wrong as well..

Notice that the fly wheel bolts have shiny places. (where the clutch disc has been rubbing.



Scars on the springs where clutch has been rubbing





Pilot bearing that is not going to fit



Sticker that tells me the trans type



after some clean up

__________________

Sorry, I don't have a part number for you. but I figured I'd let you know that our cars don't use a pilot bearing, so if your kit came with one it's definitely the wrong kit.

Make sure that the kit you order is for a 90/91 Prelude. The d2a4 didn't come on any Prelude before 90 (USDM). And it has a different spline count and also a different flywheel than the 88/89 use.

Yeah I noticed in the fly wheel there was a very thin copper sleeve so I figured as much on the pilot bearing. I did not check the spline count yet but I am thinking that clutch kit may fit other cars and I am thinking that is why it has a pilot bearing. Kind of like a generic kit?

I was thrown off by the disc rubbing. Has anyone seen that before?
