not that's interesting, there is one but it's built in and comes out the bottom? clever.

if you want to, you can send an oil a sample off, they can tell if there's coolent in the oil. if it's getting into the cyl, it should be getting past the rings into the oil too, leaving behind whatever it is they look for as coolent. I forget what exactly it is.
I'm pretty sure I smell it in the exhaust.. (unless it's E85 I'm smelling?)
The pressure has dropped from 17psi to 15psi in about 15-20 minutes.

The test sounds good, but after driving around to three autoparts stores for a coolant tester, I'm thinking I better save my energy for the head gasket job..! :banghead:

Amsoil, what did you expect? :oops:

haha.. yeah it's pricey stuff.

got oil for the car too. switching it from 5w30 mobile 1 to the newer 0w40 in amsoil.

still torn if I switch the yukon to it. since it gets lots of oil changes haha.
