WHIPPLE (engine running temps)
 

Was wondering if anyone knew what temp. I should be running. I have a 540 with a whipple and noticed this past year that i have alot of moisture when i looked under my valve covers,(milky looking oil) i am concerned that i am not getting good lube for my valve springs etc... There is no sign of moisture in the oil from my dip stick. The highest i have seen the temp go was 110 deg. and that was when i was hitting a no wake zone and slowed down. Thanks for any info...:angry-smiley-038:

You need to get the temp up.. 180-220 F when your running hard. I would make sure your gauge is accurate.
Sounds like you need a oil bypass thermostat. Just because the oil in the pan looks good doesn't always mean there's not a problem.You could have a small leak that would be just enough to milk up you covers but not the pan.

I think your water temp is way to low. It should get to about 140-160 on average even on a superecharged recreational performance engine. The moisture you're seeing is most likely because your oil temperature is not coming up high enough to take the crankcase temperatures up to a point where it cooks off the moisture and condensation thats building there. This moisture then gets in the oil when you run again and starts really screwi'n stuff up in the engine. Get your oil temps up to a 180 degree minimum with a good oil thermostat setup and they should get up over 200 degrees on hard runs. This should cook of the moisture and stop the problem.

All of this though is predicated on the hopeful fact that you don't have water system leak in the engine and no exhaust water is getting back into the engine.

WARM THAT PUPPY UP!

I run all of my supercharged engines with very cold water temps.(110*). They are built with clearances to run that cold. However, I do run an oil thermostat to get the oil temps up. Without an oil thermo. you will get condensation in the top end of the engine. CP Performance has a few different oil thermostats that are very nice and work great.

Water temp does not matter nearly as much as oil temp. Your oil temp is too low and that is why you have condensation. The oil temp is not getting hot enough to boil off the condensation. I would get an oil thermostat as Eddie said.
