Thread: Oil Leak

Tweet

I got my Nova out get some miles on new 355. When got home passenger side inner fender covered in oil. It's sprayed oil from some where. I change fuel pump and plate gasket checked bolts [fuel pump passage ] in front block. Cleaned everything up went for ride and oil is back on inner fender well. It's almost quart low. When engine was run on stand twice did'nt leak drop of oil. Seem to do it only when you got your foot in it. Had this car on jack stands running , even break torque it no oil. Only front block blowing back on bottom car.

oil leak on the pan gasket maybe.... Might not show up idling, not enough of the oil sloshing around in the pan...

What do you have for breathers or PCV valve? Could be blow-by pushing oil out past a gasket.

When you have your foot in it is when the breather comes into play, and that could be the root of your problem. At this point you may now need to change a gasket or two because of it....

A friend recently put a sbc in his elcameno.It had a high speed oil leak turned out to be the bolt holes where the smog pump bolted on they were bored all the way through but didnt leak untill it reached hiway speed. Worth takin a look.

Which side is your dipstick on? If crankcase pressure is building under load it can push the dip stick up and spew oil out the tube.

Thanks to all. Oil leak has stopped. I changed breather and re-sealed bolts front of block [ oil passage fuel pump ] . Pushing oil out timiming cover seal Took time pressure wash with hot soapy water. Wiped it all down. Took car out for ride drove it like I stole it. Came back to garage put on stands it was all dry. It was Miller time.

Heck of a good way to end a Friday!!!!!

Good deal, glad you got it all sealed up.....

It is always Miller time In Georgia if not Drink a BUD. I had a sbc leaking and ended up being the front seal . I had tighted the cover before I put on the h/b. Any way good to see you have thr leak stopped. Jimbo from Georgia

I had pull engine out of car . Oil leak came back to haunt me. Changing to one piece gasket. Started dripping from front corner. Took apart look what I found.

THIS is what I used on mine, have not had a problem since.

Ceh383 , Can you use your stock pan bolts or do they need be longer. I have Felpro 1885 coming Monday. Thin front seal for 1969 block.

Denny , Had trouble with after market oil pan fitting around timing cover , tried pull down little more. Came back to bite me on my a........... Going back to use original pan. Sandblasted cleaned up nice.

I would think stock length bolts would work, the gasket doesn't look that much thicker. I use studs on mine, it's just easier.
