posted this is in the second gen area also, but thought id post it here As well, sorry if i wasnt supposed to..... but......

"hey all, first post.....names jeff, nice to meet you, now to the point......

i have a 1995 4.3, (dont know what the injection system is called, but it looks specific to 1995

anyways, i needed to do lower intake gaskets, and when i got the lower manifold off, noticed coolant seaping out between the head and the block....so i decided to take on the head gasket..... Im a trained marine mechanic, but this (as i found out) is a whole nother` animal...

It would take me about a day 6-8 hours to do BOTH head gaskets on a mercruiser 5.7 or 260, which is just a small block chevy really, this, however is an ongoing weekend problem (the blazer is not my primary vehicle.)

So after getting EVERYTHING off, (the bolts 6 bolts toward the passanger side under the exhaust manifold. The 7 (???) bolts on top of the head, removing the ac bracket, removing the exhaust manifold itself (having to cut two of the damn bolts) i STILL cannot get the head to "pop" off. it moves about an 1/8th of an inch, then comes to a halt, like something else is holding it on. i cant for the LIFE of me see anything else that could be holding it on, is there something in the back near the firewall im missing, or could it just be sealed on there somehow (i understand the gasket creates a seal, but it shouldnt be this stuck) ? like i said, when i pry up on it with a block of wood, it moves about an 1/8th of an inch then just stops as if its getting hung up on something. Everything is out of the way (now) and i have a little room. I know there is two dowel type pins on the bottom of the head designed to hold the gasket in place, could that be whats holding it up ? does the head have to come off PERFECTLY straight ? i mean, im at a loss here......the pic doesnt help much, but its all i could get with my cell phone. Thanks in advance and i look forward to being a part of the community here.

thanks again all !!!"

 

Yup you werent suppose to!! Multiple threads about the same thing are against forum rules and when you are asking a question like this its also not helpful. Its best to keep all resposnses in one thread.

 

sorry, guess if someone could delete it that`d be cool...........

 

A mod will have to do that. It just makes it easier for everyone to have all of the info in one spot when trying to help diagnose issues is all.
