Can anyone explain if Crankcase pressure is too high, instead of pushing through the rings, it pushes through the gasket?? I am so frustrated. I am about to RTV the whole damn block and the pan. J/K.

 

No, I meant the seals behind the cam gears(mine was the ex). I didn't see the leak till I actually removed the gears and rear cover. Prior to this discover, I just saw what looked like oil coming from the drivers side front corner of the oil pan.

 

Oh, good point, let me check see if it's it. Right above the pan where the block is at the corner, no sign of oil.

It can drip down from those cam seals in the center though, behind the timing belt, etc......

 

I really think that before blowing out an oil pan gasket the dip stick would launch out of it's tube (this happend to me once). I don't see how the dipstick would hold crankcase pressure better than the oil pan gasket. That just doesn't sound likely.

I would wager that you have a problem at the area between the block and the pan or more likely you have some oil leaking down from the cam seal on the gear side and it's running down inside the timing belt cover like Sleeper said.

I don't see how you could blame the rings. Either they seal or they don't. They would have to seal inorder to cause problems in the crank case like people are suggesting but that is what they are meant to do. The ring arugument doesn't seem likely either.

Make sure to post when you find the problem and let us know how you fixed it.

 

Oil leaks suck. Mine has leaked from the return fitting for the past year....

Have you tried cleaning everything up nice and shiny so that you can see where its coming from?

 

Could it be the oil pan itself or the bottom of the block? Inspect everything is OK.

 

Okay, I'll hit the problem on the oil pan and the gasket. thanks for the comment. I'll let you guys with more info.

 

Take out the oil dip stick and run without it. See the gasket still blows under boost

 

BG, that's a good idea, I just hope oil don't spray out of it while I do this test.

Guys, I know it's from the oil pan gasket. I spray the whole motor with cleaner so it's spankn clean, plus my motor is clean as front the start ( I have seen some nasty looking ones).

 

Uh... taking the oil dipstick out will cause oil to spray EVERYWHERE. That's definetly not a good idea... Also what dustin said.. The oil pan gasket DOES have little "washers" in it.. They're more like spacers. I think they're there to keep from crushing the gasket down too much. If you forget to remove the old one from the motor (it'll stick to the stud), then it'll cause the pan to not fully seat.

About the problem.. like other people said.. check around the motor everywhere, it seems very unlikely that oil would push through the oil pan gasket...? Good luck.

i had a similar problem, where i thought my oil pan was leaking. it turned out that the pcv (black box) box was where i was getting a leakage. took it out and put hondabond around the seal and problem was gone. i should mentioned that it leaked so much under boost, that it was all over the axles and oil pan. maybe you should check it out a little closer.

 

I know this might sound stupid but it could be possible that the actuall oil pan is bent and when you put the gasket in and try to tighten it down it is not seating properly and that could be "THE WEAKEST LINK" "GOODBYE" LOL

 

Taking out the oil pan dipstick will Not make oil spray anwhere. Notice how high that metal tube is from the oil pan? How could oil jump up that high?

 

No, not leaking from the black box, I removed it already. I took the timing belt case, crank pulley, driver side under mount, inner timing belt cover all off to check if oil pump is leak and no, no sign of leak. I should take a picture of this, if you see it, you can see oil sipped through the gasket from previous boosting.

I purchased brand new oil pan gasket for 95' integra GSR four times, no there is no washer you were talking about. Maybe you are referring to other model but I can assure you it's not the GSR ones unless there is washer ones floating around at the acura dealership. Anyone else has 95' GSR oil pan gasket that has washer?? I want to buy one to try it out.

Oil spray out or not if dip stick is out I couldn't confirm. But I think leaving the black box top holes open would also do the trick.

 

"How could oil jump up that high?" Why don't YOU try leaving it out for a day... hell, even just for a few hours.. then maybe you'll change your mind.

-Mike

 

Okay okay, maybe oil jump out of there, but venting the damn crank case is a good idea. I don't think I need to do so since I have no pcv valve anyway. You guys should see the size of the barb I had that replace the pvc which connect straight to a catch can. I think crankcase was been vented but not enough??

Hey, how high of a oil pressure do you guys see at full throttle full boost on your gauge?? I have greddy oil pressure gauge so it shows 6.2 kg/cm2 or so the highest mark as I go full boost, I idle at 2.0 kg/cm2. Anyone?? Oh, how do you convert kg/cm2 to psi??

Ok.. it's not exactly a "washer" like I said.. it's a spacer/dowel built INTO the oil pan gasket.. You know where the stud is for the oil pan on the rear main seal? There is a small spacer built into that hole in the gasket..

Next time you have the gasket out feel in that area and you'll notice it's not as squishy. I'm not saying that this is your problem, just saying there is a dowel in the gasket. Judging by what you're saying and how slight of a leak it is, this probably isn't the problem.

Regarding the leak.. that's very strange.. maybe the surfaces aren't straight..?

-Mike

 

Wow.. you're seeing pretty high oil pressure..? 6 bar is about 90 psi.. Definetly high. I see 75 tops. What oil pump are you using? Vtec pump in a non vtec block? That will usually do it.

The excessive pressure could definetly be causing the oil to blow through a seal, causing a leak..

-Mike

 

That's weird, I have stock pump which equipped with block. I bought the block brand spanking new from the dealership. Only thing I did was installing rods and pistons. I got even more interesting news then. I'v got Greddy oil pressure sensor which is not installed near the pump or near stock location. I have a Greddy oil relocator kit which put the filter on the fire wall where the brake lines are. The sensor is tapped on that relocator. Now, you think my oil pressure is way high then I think pressure is way way high at the pump unless pressure is constant no matter how distanced it is, anyone can confirm??

90psi huh, it is kinda high. And it climb that high not even hitting boost yet. I can see oil pressure limiter or some sort of mechism limiting it past 6.0 or 6.2 kg/cm2. Maybe my gauge is wrong then.

One last thing... Try driving around w/o boosting but revving the motor up.. See if you still have an oil leak. Oil pressure has to do w/ rpm and not vacuum, so that should tell you if it's from the boost or pressure. Also, that pressure definetly seems high.. Most people get ~20 psi at idle after the oil has fully warmed up, and you're getting ~30. Newer pumps tend to have a little more pressure but that seems a little high.. Good luck.

-Mike

 

Thanks for the look out slowTeg.

 

Hey, np man.. If pressure doesn't seem to drop, and you can't fix the leak.. It might be worth it to try swapping the spring in the pump for another one. It's definetly a pita to have to pull the pump but you might have no choice.. Good luck.

-Mike

 

haha, I found a thread that talk about high oil pressure. They said smaller oil filter will increase oil pressure. Well, what you know, the greddy oil filter relocator requires the small 1986 corolla filter. Hum.. could that be the problem?? BTW, how the hell would a smaller oil filter create a higher pressure?

 

Smaller oil filter, less volume..guess that causes more pressure?
