pouring oil above drain plate.

Post by kokodabobo on Fri Feb 03, 2012 2:23 pm

i recently dropped the engine to fix a leak coming from the push rod tube. checked the rear main seal and the oil cooler and all of that was good. but after putting the engine back in and starting my car it pours oil from about two inches above the drain plateand up in the engine. i cant figure out where its coming from and its like pouring oil like you would out of a bottle. its bad. any ideas?

Above the drain plate? Since that is on the very bottom, that leaves the entire rest of the engine. Help us visualize a little better...picture?

you might have tweaked it while putting the engine back in. Could also be the trany seal. Trany oil has a very distinctive "rotten egg" smell.

If you have oil pooling all over the top of the engine the leak is likely comming from the oil cooler. Hard to tell from the pic but there should be some gaskets between the stand and the engine. Also there is a deflector plate that should be sandwiched in there as well.

i agree with glenn take the seal out and install another one, i have found napa has some relly good real main seals . they are not like the el cheapos you buy at the other parts store that start with A. When you pulled the engine you sould have been able to see a wet area with that much oil, also check your case, they will rotten in water so there might be a hole somewhere.

Well I pulled the engine because I had a small oil leak coming from the push rod tube and I solved that leak and that was the only wet spot. Oil cooler was fine and everything else looked ok. But after we put it back in and ran it it has an oil leak 20xs worse and coming from a different area. I'll stop by napa and change the main seal soon. I'll also check the cam plug. Thanks for the info. Hopefully I can get this resolved soon.

And as for the case halves I've never had one there before. I only had a short time to look at it before I had to leave but I was uncertain if it was gas or oil. I'll take a closer look when I gat home and check and see if it was coming from the carb or somewhere else

so it was coming from the case halves underneath and it looks like oil but it has a gas smell mixed with it. dont know if that helps at all. but i got under it today with it running and it was only leaking from that crease and not from further above it.

If it has a gas smell that could be the fuel pump leaking into the case or it could be some leaky rings allowing burnt fuel mixing with crank case vapor to get into the oil.

if u get an electric pump get a good one. if you plan to get a cheap one, stay witht he mechanical pump. i'd recommend a carter electric inline rotary pump. i got mine from summit (i think it was like $65ish). been over 2 years, and no problems.

If you're running the stock carb, I'd run a mechanical fuel pump for simplicity's sake

New mechanical pumps are around $28 bucs. Get two and put one in your rescue/parts bag, you never know when you or someone you're cruising with will need one.
