head gasket???

[pontiacross]

so I have one that I have never seen and unfortunately it on my own truck...
-loosing coolant
-heavy white smoke (smells like coolant) and hydro locking (Both of these are intermintant and on start up only}
-milky oil
so my initial thought is a head gasket but could an injector cup cause this, my thought is no since the injector seals at the bottom of the head not the cup and I have not seen any signs of fuel in the coolant. has any one run into cracked heads or pin hole in the cylinder on these ?

this is on my 97 and it has been studded but all the performance parts were on it when I got it so not sure who installed them and if anything was done correctly

Have you pulled the valve covers? I would suspect cracked cylinder wall over a HG.

Especially if there is a thick slime under the VCs.

that is what I am afraid of. I haven't pulled the covers but can tell it is pretty greasy in there through the filler cap.

I have been pretty easy on the truck since I bought it because I have been trying to limp a bad trans along as long as I can but I'm sure it saw some abuse before I got to it. it has some pretty decent size hybrid injectors, an H2E, and had propane injection on it (I sold that off as soon as I got it though)

don't have time to deal with this in the middle of harvest so I may try to get the dually parts truck I bough running and drive it while going completely though this one

Have you pressurized the cooling system?

haven't had time to do anything but drag it out of the way. if we get a rain sunday I might have time to look at it a little more
