How much Oil in Bilge is Acceptable?
 

Just had my 540s built. I noticed that I am getting a little water in the bildge, along with some oil. Is something that is common place with high performance engines. I didn't have any water or oil with my 502s. When I pull the drain plug it does create quite an oil slick. Is something that is correctable? Thanks.

I agree with trick, you want to find the source of the oil leak especially if they are fresh motors, maybe a gasket or surface is not sealing up properly.

Couldn't agree more - no oil what so ever

You have a leak. Try to get a leak detection kit - NAPA has them, they have a dye you put in the oil and a black light flashlight. Run the engine for a little while and then shine the light on it. It is the easiest way to pinpoint the leak.

Try to wipe the engine down before doing this.

put some diapers down and see where its comming from, could be from many things most serious would be blow by with a new mtr

meanwhile make sure you pour some bilge cleaner down there, it will help break up the oil and not leave a slick when you pull the plug.

Check the front and back of the intake, and around the distributer, front timing cover and valve covers are most common leaks.

West Marine has oil absorbant socks. I strap one in my bilge just to soak up stuff I don't want pumpd overboard or to drain out. They only absorb petroleum products.

Sounds to me like a problem I had with an "old school" builder who insisted on using the OEM cork gaskets on the intake manifold to block. (I do all my own assembly now) In our marine application they would always blow out and at speed the oil would exit from the pushed out gasket in the area to the rear of the intake where it is supposed to seal off the lifter valley area. Take your clean cloth and wipe back there. It's a tough area to see but you might be able feel the pushed out gasket and you can sure find the oil. As for an answer to the thread topic: NONE! --- Jer

Just don't let this guy GOODT (Joe Heller) work on your boat. He is a dirtbag and still owes me $1,000.00 :mad:

The oil should be in the pan....not the bilge. Seems like you've had several engine related issues since your engines were built this year---hope it goes better for you.
