if i saw a little “Mayo” in the Radiator Cap, Does that mean one thing and one thing only?
I want to make sure im not going -Nuts.- One time, on my Iron Duke 2.5L “Tech4″ Oldsmobile, i saw a small amount of “Mayo” on my Pressurized Expansion Tank. it only happened once, weird.. it seems consistent with the other symptoms: a Constant “Looping” idle, not really Rough.. and i took this video a month back, it had done this for awhile.
Now, i noticed Hesitation upon taking off from lights.. SOMETIMES. yesterday, it did it during a short trip.Today, it didnt do it al all. it also seems to run smoother if i DONT let it warm up, weird…
I havent seen the Mayo since..
What could be going on?
(This is at start-up on a cold dya, it doesnt always do this just most of the time, it varies) http://www.youtube.com/watch?v=Qo1Iv4L4vVQ – Stops in about 5 minutes, most was 8 one day…
That just looks like steam from condensation in the exhaust system.
Do you have to add coolant very often? When was the last tune up? Service?
You can get a cooling system pressure test to see if a head gasket is bad, but I think you just need to do some maintenance.
