Ok so I have 94' Honda accord DX 2.2L vtec w/ an f22b automatic, I got it from a good friend who got it with a fresh head gasket. It's leaking about a 1/2 to 1 qt every other day appx. I knows its not the oil pressure switch, just got that done, just got the oil pan gasket done, not the valve cover.

It's leaking from the passenger side rear corner of the engine, the first mechanic did all the other work on it (except the hg) and sprayed it all down cause the entire engine was covered in oil and said it had to be the head gasket. He thinks the mechanic who did the HG before didn't do a good job because he didn't change out the water pump or timing belt, which got done after. The upper end looks new because its all shiny but IDK (maybe new head?).

Anyways the second mechanic was a little better and had a camera to look around and said it might be the HG but wasn't sure because it was covered by the transfer case but it was for sure the rear passenger side of the engine and was leaking down some tube. It leaks the majority when its running so I can only think it could be a cracked block or the HG, but that was just done... what else is in that area that it could be please help!!! thanks in advanced.

Following parts were just done:
-oil filter (yes it is tight)
- brakes and tires
-oil pan gasket (which is missing a bolt but isnt leaking)
-water pump timing belt and radiator
-distributor wires and plugs

The whole bottom half of the engine is covered front to back and pretty much the whole front half bottom of the car

 

How many miles? Is the oil leaking primarily near/from the joint between the block and transmission? Failure of the main seal on the right side of the engine can lead to a substantial oil leak. Unfortunately, the transmission has to be pulled to get to it.

 

I'm fairly confident you'll find it is the rubber seal between the engine block and the oil filter mounting plate (some call it the oil cooler). Pretty tough to spot unless you know exactly where to find it. I've got a similar situation brewing in my 1993 Accord and my research seems to point to this. I had an '89 Accord that had this exact condition and it was this seal. It was a tough area to reach from above and fix. It looks like it is still a weakness in my 1993. Other authors on the web have found oil sensors not sealed also. Mine has 242,000 miles.

 

possible distributor housing or o-ring, valve cover gasket, rear main oil seal.
cam seal, balance seal. crank seal...
those are usually the stuff that leaks on accords...

 

Wow you guys are awesome, 167,000 miles It is leaking onto a pipe/hose that goes down the back side of the engine from left to right (passenger side to drivers side) and the mechanic said it was covered by the transfer case... its not the valve cover.

Isn't the rear main seal on the drivers side?
And if it was the distributor o-ring wouldn't you be able to clearly see it?

 

Or better know as the head gasket. He's telling you this isn't the prob. But sounds like a problem I haven't run in to... Yet.

 

I'm over my head on specifics of your 1994 Accord. My 1993 has the front of the engine on the driver's side, meaning the transmission and consequently the rear main engine seal on the passenger's side also. The oil filter mounting is above the drive axle powering the driver's side wheel and below the intake manifold.

 

The valve cover gasket (VCG) and the head gasket (HG) are two completely different things. The VCG goes between the valve cover and the head, and is a pretty easy and relatively cheap replacement. The HG goes between the head and the block, and requires much more time and money.

 

 

Sounds like the rear main to me. You can pull the cover on the bottom of the tranny and look at the flywheel if that has oil on it then rear main is the suspect

 

I also had same issue on Honda Accord 1994 EX F22B1(Auto) I am also seeing Oil below the right rear corner of Engine may be you can say close to the Tie rod or Oil filter not sure where it is coming from any suggestions????

 

Before you go changing parts, might I suggest one small procedure?


- Take the car to a carwash.
- Thoroughly Pressure wash the engine, top, bottom, rear, and sides.
- Take the car home, dry the engine off with an air blower.
- Lift the car up, start it.
- Look for oil leaks.

 

I had it degreased twice the oil leak is coverd by the transfer case or bell housing, thanks for all the info the mechanics said the rear main seal was on the drivers side, Guess he was wrong! and the oil filter is on the passenger side, but it is tight and not leaking from there!!!!

The head gasket will be the most expensive of all correct?

and which side is the rear main seal on??? my tranny is on the pass side.

 

naw man rear main is passenger side between trans and engine...he would have been right if you had a V6........cause that layout is opposite of the I4 cars up to 2003 accord when the I4 got reversed layout and that is when the trans is on the driver's side


prolly not a HG since it is by FAR more likely that you would have oil in coolant before oil leaked out of the engine via HG

 

strating to think it is the rear main i looked under the car and it was leaking between the engine and tranny right in the middle i took a pic....

 

I'm guessing a Rear main seal (passenger's side by the transmission)...although, I just replaced an oil pan gasket leaking in the same place on my 92 F22A6. If that missing bolt you mentioned is down on this end, that might be your problem.

To check for the rear main seal leak, pull the plug next to the Engine Model stamp. To do this, pop the hood and look down for a black/grayish rubber plug thing between your exhuast manifold and top coolant to rad hose. It should be right near the place where your engine is stamped F22xx or whatever your engine's model is. Pull this plug and see if you see any oil evidence on the flywheel in there. If no oil, I'd guess oil pan or *maybe* cam/distributor seal. If there is oil in there, it's almost definitely rear main seal.

 

Can oil on the flywheel cause engine damage?

 

And there is just so much oil, its even on the drivers side front (closest to headlights) corner of the engine from the head gasket down.... which is the complete opposite corner we found it leaking from!

its clearly not a valve cover gasket

 

no but it can toast your clutch if it is a manual

 

Oil from the rear main shouldn't be able to get to the left front corner of the engine, leaks typically go down (gravity) and back (air flow). Still sounds like rear main seal on the right side of the engine. As far as the left side, did they replace the cam, balance shaft, and crank seals when the timing belt was done?

Do check the coolant for evidence of oil (and the oil for evidence of coolant). It is relatively easy to pull the valve cover and check the torque on the head bolts.

 

your oil pan gasket has little tiny metal rings in some of the bolt holes. its possible that one stuck to the block and the new gasket that gets put in has one in the same place, not letting the gasket to be tightened fully. this has happened to me before behind the dust shield, made me think it was the main seal. had the drop the tranny twice before i found it.

 

thats your rear main seal that had a melt down. i would bet on it. do a test on the head gasket with a head gasket tester to easily rule out the head gasket without turnin one wrench. then replace your rear main seal. the pics were awsome for diagnosing this problem online

 

there are a lot of seals that it could be. any competent mechanic would be able to trace it though. and if the same mechanic that gave you a question mark on the leak did the oil pan gasket, i wouldnt rule that out. but if its passenger side, and definitely coming from the engine, not trans.....then look to make sure there's no leaks from the topside leaking down, such as distributor o-ring or housing or valve cover gasket. if you're confident they sealed the oil pan well, then its probably the rear main seal.

 

Yes its at or below the HG so that rules out distributor and valve cover and when I said the passenger side rear corner, thats when it was on ramps so it may have looked like the rear side but when its lifted flat it comes out directly in the middle of the engine trans, but when i put cardboard under it there was a line leaking from left to right, so im going to do the cardboard thing again and watch it, my mechanic is out of town until sunday so thats when Im bringing it in.

Just want to thank everyone for there input i've been reading up non stop through-out the forum to try to get as much info as possible on my own.

 

the card board aint gonna help you unless you put it exactly level with no pitch and you haveit inside where wind wont push the oil in different directions. well the ramps do work as you know...but i think ramps specify that they are for RWD vehicles only. youre the first one i heard of using ramps on your FWD car. i learned somethin new already today. i am glad youwere able to figure out how to rule out your distributor and valve cover gasket. you would be surprised how often i see people in the forums who have no clue how to do that. about your oil pan gasket,...it could be leaking too. it most likely is at least seeping if you havent replaced it in a while. but it wont pour out the rear like that unless you have too much oil in the engine already and you have a sevearly damaged gasket already, or unless you have the damaged gasket and drive in a NASCAR race all day. (make alot of left turns at high speed). i doubt youre doing either of those though
