Re: Oil in my Radiator!!! -- Please Help

You might try pressurerising your cooling system and using a stethoscope to locate where the air is leaking into engine.This may give you a general area in which to look at.Also is it possible that you have a engine oil heat exchanger tied into the coolant system?I know the V10 have this as the coolant lines run down to the oil filter adapter.
Good Luck,Wildhare

Even if a cooling system additive had a 1% chance of working, I'd try it before changing the engine. Cost is low compared to replacement.

They probably have better tools nowdays, but a buddy worked at a radiator shop and they could sample the gases in the radiator to determine if there was a head gasket leak.

The engine oil cooler is a real possibility, since my SMB has an OEM towing package. My guess, from the amount of oil in the coolant, is that the leak may be too slow to find with a stethoscope, but it cannot hurt to try.

And yea, Mike, I think it is a no brainer to try the cooling additive. Even if it doesn't work and really screws things up, I'd have to replace the engine anyway. Besides the small additional cost, what's the downside?

Thanks. Already tested twice, no hydrocarbon gases in the coolant. It's ironic that I am disappointed that I do not have a blown head gasket. :-(

How about transmission oil? I know I have a Chevy but oil from the tranny goes through the rad area to cool off... Good luck...

Re: Oil in my Radiator!!! -- Please Help

Generally red vs. black, never had it mixed with antifreeze, but generally pretty easy to tell the difference with an Auto.

Was hoping for an update on this, any word?
