Oil problems
Posted by: Medic68W ()

So I just had a new clutch kit installed, new trans/clutch fluid, as well as a new oil filter and oil about three days ago on a 1960 manual caveman. Yesterday i encountered what i believe to be a vapor lock. I filled up the oil this morning, and already, the oil has dropped down to just over half way between the empty and full lines on the dipstick. It's got a visible oil leak somewhere, just a few drops on the garage floor every once in a while. Does anyone know what could be going on? Wrong Oil? Filter not on all the way, even though it feels very secure? Engine running to hot and cooking the oil off? Anything would help!

My 65 4-door use to be Happiest half way between "Needs 1 Quart and Full'. Would always fill it to Full, but weeks later would hover there at the half-way mark. Didn't drip much either.
Like you said "Just a few drops on the garage floor every once in a while"
I've heard others have the same experience. (Not much of a problem if it Stays there!) smileys with beer

Alaso, there are different length dip sticks. after 59 years, it might have been swapped out with another one...

Oil doesn't cook off. It's either leaking or burning. You'll have to investigate the leak. No way for us to help without a description.

Keep driving and watch the oil level.... bet it stays at 1/2 down as mentioned.

Yesterday i encountered what i believe to be a vapor lock.

Vapor lock is a fuel condition, from the fuel evaporating in the fuel system before the fuel pump. The pump can only pump so much air,and if the fuel is continuing to evaporate, then that is what the fuel pump pumps, vapor. Carburetors do not operate on vapor (I know, the engine does, but fuel has to get into the carburetor to become vapor), so the engine stops running.

If you have an oil vapor problem, things are way too hot!eye popping smiley

Since you said it was running hot.

Have you checked the top of the Oil Cooler for debris, leaves, Duff?

Access panel has two screws and is under generator.

usually can clear with a small paint brush.
