hi, don't wanna sound like I'm ranting (probably will anyway) but my car seems to develop new and interesting things for me to fix every week . I noticed my car was slowly dripping oil behind the head/block (makes a small puddle on the block) where the AAAAA code is for the bearings. It looked like it was dripping oil from the valvecover/cam seals - pull the valve cover and notice the corner was leaking a lil bit, threw some honda bond there and where the cam caps go. I put a new pcv valve in because the old one was clogged (even brake cleaner didn't help), plus I noticed some oil buildup there aswell. Fire it up, seems good, go for a nice long drive and everything was sweet. Now this morning I fire the car up, noticed the drip leak was back, this time with a vengance. I had to shut the car off because I could hear something spraying out, I pop the hood and see that there was oil spraying from somewhere, got on the hood, back of the valvecover, all over the half-shaft, everywhere.
I was searching some stuff and noticed some people were talking about the oil-cooler o-ring leaking and causing a bad leak like that. I also read up about the balance-shaft seals, but that wouldn't be visible like that (I have the upper/lower timing covers in). I am also thinking it could be the oil pressure gauge line, but thats a copper line that came installed when I got the car, never leaked before, but I guess it would spray like that if there was a problem.
I'm just trying to figure out what could have gone wrong now, seems like theres a family of gremlins living under my intake manifold or sumthin. Would a oil-cooler o-ring audibly spray oil out like it was its job? I wouldn't doubt it, but its really wierd. Anyways, sorry for the rant, I just wanna drive the thing again (and its starting to get nice outside finally .

I was just checkin more stuff on the oil cooler o-ring, seems like the culprit. I might have to take a day offa class to do it. I just hope thats gonna be it for a while, full time work n school doens't leave much time for me to be fixin stuff lol.
I wonder what the part # is for the o-ring, ah, I'll just find out tomorrow. I'll (hopefully) have a update soon w/ the part # if anyone wants it.

#33, PN 31504 O-RING (62.4X3.1)

 

thanks Hawkze, looks like the same procedure as changing the b18c oil cooler o-ring when I was rebuilding it for my teg. I had the engine out, but shouldn't be that much of a difference (get under car, remove oil filter, unbolt the stud/bolt thing, move cooler out of the way, remove/scrape old o-ring off and put new one in w/ some hondabond to hold it up, reinstall everything and cross fingers while starting car).

Yeah, it's pretty easy. Have a 30mm socket ready

No sir, 30mm.

 

Thanks hawkze, I was looking up the same info

 

Ok, fixed the o-ring - not as bad as it seems (just jack the car up pretty high).
The old o-ring was shot, split on the top side, flat and felt like hard plastic (I'll put pics l8r lol).

-remove oil filter
-use a 30mm (extension optional) to remove the stud bolt holding the cooler in
-you can move the oil cooler out of the way (its held up by hoses)
-the o-ring sits on the back of the cooler, use a screwdriver (I had to anyway) to pop it out
-clean the back of the block (or in my case; intake manifold, firewall, axles, strut towers, steering rack, while ur in there)
-throw some honda-bond in the groove and set the new o-ring in (had to work it in a bit but it works)
-carefully put the oil cooler + stud back in
-hand thread it then tighten it up w the 30mm
-put the oil filter on and top off
-fire up and make sure theres no leaks
-celebrate w/ a ice-cold corona (edit, with lime)

hope that helps

good job, glad it all worked out for you.

Our preludes are getting old, but I'd still rather fix things from time to time than have a car payment for something newer that I don't even like as much. Look at it this way, once you fix the problem, it should be good for another 10-15 years

 

i know this is a dumb question but to remove the oil cooler O ring in my 93 sr engine would i have to drain the oil(im assuming yes)?

 

any pictures...looks like this is what i have to do now. i changed the cam seal but im still drippin oil.

 

No ....just take the filter off,take the 30mm bolt /nut out,remove oil cooler ,remove old crusty o-ring,install new one with a dab of oil to hold it in place...tighten 30mm nut back down , install filter.....
