My b18c5 turbo motor is leaking tords the bottom of the block by the oil pan and oil pump. We thought that the problem was the o ring in the oil pump but we put new o ring on the pump and the crankshaft seal. We used good amounts of honda bond hoping for a strong seal.
The leak didnt go away
We tried replacing the oil pan gasket and used rtv black on both sides of the gasket
It appears to be fine there but the leak is still coming.

Here is the list of places that we checked

Breather on the back of the block
Oil feed line for turbo
Oil filter

ALL CHECKED OUT DRY no signs of oil

I know someone has had this problem before so please help me out.
Trying to take it out to the race track by this friday so im trying everything possible

THANKS

 

if the leaks are coming from the oil pan. check the tranny side or the timing belt side. oil pan gasket have two washer and if you pulled the gasket out and didn't check all the bolts. chances are you left the washer in the bolt. had the problem and i found a washer on the tranny side left from the previous install. also make sure you carefully take the gasket out so you dont have to buy another set. both one from acura and cost me over 45 bucks. good luck.

 

Pics of front of engine? Are you sure it's not coming from higher up and leaking down? Check the plastic timing cover and see if there is any oil trails from a higher location (cams and such)

 

I have the same problem on my Booted R motor ,

we originally thought it was the o ring as well , but on that black box on the block , but it wasnt , we just rebuilt it this week tho , so it should have stopped ( new gaskets bolts and what not .

if it dosent im gonna rip that black box off ,
if it does leak ill let ya know what i find tho , maybe that will help ya out a lil bit

Good luck man

PS , if its not THAT bad , then whatever , but i know how annoying it is , if u know where its comin from its oine thing , if u dont , its tears you up inside , sucks ,


anywho , good luck with it

 

no signs of oil in the covers. i only pulled the top one but i could see 2/3 of the way down and the timing belt was dry. I couldnt find a leak on the back so i figured it must be up top so i check the cam seals and they checked out fine

 

yeah tell me about it

the leak is pretty nasty gets all over my advans and my underside of the car and engine bay was spotless now i have alot of clean up to do.

well i was planning on getting my other wastegate installed today and tune tomorrow so i could take it out to the track this weekend for high school drags.

im really doubting that it will be out in time

idk what to do at this point i tried it all

 

I probably tired this but hey ya never know. If it a massive puddle or a drip? If its a drip it can be helpful. Match the drip to the location on the bottom of the engine, and concentrate on that are. Yes, i know it can leak and drip in a totally different part.

Things to try also:

If you have a oil pressure sending unit on a brass T fitting they tend to crack easily.
Also if you got a oil temp sensor check that too.

 

its green cuz i used oil dye and black light but i couldnt use the blacklight and record but heres the leak
