UH OH! Oil in the spark plugs!

Coming home from subway today I tried hopping on the car and it sounded like loud popcorn, it sounded like from the exhaust, but I can't be certain. In 5th gear it bucked me a couple times, and on my way back out it shut off at a stop sign.

For ****s and giggles I decided to check the plugs, and wa-la. There is oil at the bottom of the 4th spark plug (driver size). Maybe a little in the 1st but not as much.

It's not flooded, but the bottom of the plug is all wet, and you can see it when looking down.

What am I looking at fella's? Big or cheap fix? Hopefully a seal or gasket? When I did my time I did replace the 4 o ring gaskets on the valve. There is no oil on the walls or at the top, only at the bottom.

Re: UH OH! Oil in the spark plugs!

oil in the plugs shouldnt be the reason the car stalled or the bucking your getting. oil thing is a cheap fix just need new rubber gaskets for the valve cover

Re: UH OH! Oil in the spark plugs!

I dont think its the valve cover, I replaced it no more then 2-3 months ago. It's only at the bottom of one plug.

The bucking and other problems I'm leaning toward the TPS, thats where all this started. But my father said the TPS shouldn't cause a misfire, so I went ahead and checked the spark plugs just to make sure they weren't worn to ****.

On the note, will a bad TPS cause the pop sound?

Re: UH OH! Oil in the spark plugs!

If the TPS sensor reads erratically yes it can cause a pop sound.
Think, if the sensor reads normal say 1.2v and then has a internal short and jumps to 5v, the ECM think that you just floored it very fast and is going to adjust fuel amount, the MAP sensors is going to not change since the throttle was not actually opened. The ECM is still going to give it more fuel than you need and cause a rich misfire. The opposite, TPS reads lower than acutal, can happen and it can cause a lean misfire.
Only if the TPS goes over or under the spec voltage will it throw a CEL, and run the fuel map of the MAP sensor.

Re: UH OH! Oil in the spark plugs!

sounds like a nice mis-fire, have you messed with the car recently? the oil on the sparkplugs should burn off if anything so i dount thats the issue. Sounds like something with timing, maybe your distributor rotor is wearing out.

Re: UH OH! Oil in the spark plugs!

i haven't gotten that popping sound, but yes, replace the rubber spark plug gaskets. i also found oil, in my #3 spark plug tube, while i was in the process of changing my timing belt and water pump.

Re: UH OH! Oil in the spark plugs!

The oil leak isn't a problem. Close examination shows it's not leaking in, or from the combustion chamber, so it's probably the bottom o ring seal. To fix it I'll need to take off the cams and such, I'll do it next month, and replace the cam seal as well.

As for the TPS, I still don't have a check engine light, OBOI, and that sort of proves that it's the TPS more and more, for a misfire caused by anything else would usually trigger the CEL.

TPS is in the mail and on the way, thanks for the input guys. =)

The popping is new, but the other symptoms, such as the sluggish acceleration, shutting off at a stop, and the surge idle when it chooses to do so point more toward the TPS. If I replace it and it doesn't get better I'll look into the cap.

Re: UH OH! Oil in the spark plugs!

Check ur timing first. Make sure the cam gears are where they need to be had this problem a couple weeks ago. When I redid my timing problem went away excess oil burned no more retarded acceleration. I just check the plugs every now and then to see if there's oil on them. Check the cheap sh!t first before throwing money at it. Learned that the hard way -__-

Re: UH OH! Oil in the spark plugs!

20 dollars is pretty cheap lol.

But I changed my timing belt months ago, why would it just start acting up now? Getting it checked with a gun by a mechanic is on my list, just for measure, but I wouldn't think it to be the cause of what I've been going threw.

Its tough to mess up the timing on a h22 with h23 manual tensioner. There was 0 room for mistakes, it took literally hours to snug that belt on, no such thing as half a tooth off lol. But I'll go make sure.

Trust me man I know. I have the manual tensioner on my h22. It really and truly is a b!tch to do. It's like u have clear an entire Saturday to do it and get it done correctly. Also u can check the spark plug grommets. Maybe the silicone is shot ad is allowing oil to creep on ur plugs.

Re: UH OH! Oil in the spark plugs!

God. Could a vaccum line cause misfires? I noticed unplugged line on the right side (driver side) of the IM, it connects to the circle thing with a small bent tube coming from it. What's that called? Well I plugged it in and ripped the lude about 2 miles and no misfires or bucking.

Needless to say ill replace the sensor now that I have it.

Re: UH OH! Oil in the spark plugs!

Scratch that entirely.

I misfired so bad in 2nd gear that it kicked my head back. Rough idle is still there too, once warm.

I'll update when I swap the sensor tomorrow.

Re: UH OH! Oil in the spark plugs!

hey man i had this same problem minus the whole TPS problem your having... what is that anyhow? lol My problem was the distrubutor rotor underneath the cap never had a screw on it to keep it in place nore has a whole in the rod that comes out of the distributor so it just pushes on... well it wore out and would run fine for about 10-15 min then would have a loud pop or backfire when i went to floor it or had in a higher gear but lower RPM's. So i looked underneath and i saw that the rotor has worned out and you could wiggle it back and forths. I took some thing plumber tape and wrap it around the rod and shoved the rotor back on and havent had any problems since then. And oh yeah i got oil on all 4 plugs and she still runs so yeah... Hope that helps man :) Also i have a new one that im gonna replace but was told either to drill a hole for a screw or glue it on! that is what SAAB does over hear in Europe apparently haha

Re: UH OH! Oil in the spark plugs!

I changed the tps cause I had misfires and a rough idle. Now im not sure if replacing the tps or screwing with the distributer cap fixed the misfires and stalling but so far today it hasn't happened. But the rough idle is there still when warm, and it only started after hoping on it for a civic trying me off the light. Im thinking the misfires and idle aren't related. Im going to check my lines and air control valve again. Rough idle could be anything, at least its not turning off anymore.
