Re: Help with 98 3.8L V6 coolant leak
Thanks for the responses. There is NO sign of coolant (milky turds or froth) in the oil/oil fill cap/dipstick etc. BUT there has been traces of oil in the coolant and cooling system. The engine has not overheated. The coolant was not flushed for 90k miles (I know - shame on me for neglecting it - had other cars with worse problems that made doing my flushes take a back seat). I did it this past fall when I noticed that burnt maple syrup smell running my heater for the first time and that the coolant was low and sludgy. I ran a compression check on the coolant system as well as the heads and there is no sign of a leak. I did replace the radiator cap "just in case" and I'm still losing the coolant. So, basically, there is no obvious "LOOK AT ME" symptom that's telling me where I'm losing the coolant. I'll go ahead and try that combustion leak test but I already have the cooling system drained and dismantled to change the thermostat. Major bummer to have to go backwards to look for the leak. It's cold out in that garage and I was hoping to limit my "labor" hours =) Again, thank you for the advice, suggestions, and just letting me grumble about my woes.
