Hello.

I am hoping someone can point me in the right direction...

I have an older Toyota FGC 15. I don't know the year (probably early 80's or mid to late 70's).

It has a 5r 4 cylinder propane engine.

The problem is fluid in the oil after about 15-30 hours after each oil change. I had the head gasket changed last year as my mechanic assured me that that was the culprit. Apparently not.

I change the oil after it turns milky (usually around 20 hours of use)
. The problem keeps reappearing. I use 15/40 oil.

After the head gasket was replaced and I saw that the problem remained, I bought a new regulator and put it on- which did not solve the problem.

Recently, I sent the oil away for analysis. No antifreeze was present.

I would greatly appreciate any advice given. I am at a loss.

Thank you

Jim
