Hey all, got a serious problem going on right now with my Blazer. I have a 96 Blazer i just had to repo from a guy, well when i picked it up I found that theree was over 15 quarts of water and oil in the engine. No wonder he didn't want to pay for it any more. I have had a similar problem before with a Ranger of mine, but I caught that rather quickly, the Blazer will not start at all now.

I am treating this as blown head gaskets. I know I need to get a compression tester this week to check the cylinders, but what other "simple" tests could I do to narrow it down? I am going to have the heads crack checked while they are off, I am willing to bet that atleast on is cracked.

Hey any help you guys can give me would be helpful. Gotta get this thing running so I can sell it. Thanks again.

PS...Hey can any one tell me what the standard compression is on one of the motors, I am assuming between 120-130lbs, it has been so long since I did anything "mechanical"!

 

my 3.8L engine had a compression of 185-195 psi

is the oil yogurt looking? that would definately indicate coolant
in the oil.

dam wish I had a 4.3L vortec-head engine, even if it had a busted head gasket, thats easy to fix

 

pressure check the cooling system. who knows maybe since the guy new it was geting repd he just dumped water in the engine

 

head gaskets are not uncommon, but a more (extremely) common problem is the intake gaskets leaking coolant into the lifter valley

 

you know, after getting it apart this was the thought that I had, the heads looked alright, but I wasn't sure. So better safe than soory, took it all apart and going to get it back up and going next weekend. Of course I am going to take the heads in to get crack checked just in case, but they look suprisingly good. Worst part about the whole thing is all the damn wires. Man I cant get over how many wires there are under that hood!
