Hey Mike,

How are ya?

I'd say the thing you have to worry about the most is the rings/cylinder walls, bearings, etc.

Antifreeze has a sneaky way of slipping past the rings into the engine oil.

And why are you worried about your cat? You didn't pass the smog test the last time with it. :sillylol:

Seriously, I don't know about the cat. I do know that running rich can cause it to coat itself from excess heat, but I don't see why the antifreeze would do that. It should vaporize with no harmful effects.

What I'd do is post this in the General/Tech Engine board and see if Vader, RB, ede, or five7kid (as well as many others) knows. Just don't use their names in the title or they won't respond.

TTYL,
AJ

 

as long as your now changing and fixing anything you should be ol eapecially with the advise above,... good thing it wanst happening with engine still running normal.

good luck with the fix up
