Alright guys. I have antifreeze leaking from the top of the engine somewhere. I can narrow it down to right below and to the right of the intake. It drips/pours down onto the differential and oil pan, but only after I've gotten it up to running temp and not while it's running. When I squeeze any hoses I don't get drips and all connections look fine. Is there a chance that the engine block cracked? I went through a gallon in about a week and a half before I saw the leak. Any help would really be appreciated.

 

intake gaskets, do it soon or you will have coolant in your oil and your engine will start knocking... happened to me.

 

^^^^ditto

my intake gasket leaked out on top end in the "valleys" at each valve cover....better get on it quick.

 

Ya intake gaskets going bad are super common on blazers.

 

Wow. Thanks for the help. What am I looking at time/difficulty/money wise? Sadly I need to drive it to get to work tomorrow I really appreciate the help. Im sure you guys just saved me a TON of money.

 

It's cheap parts but expensive labor if you cant do it yourself.

 

i got the gasket kit off rockauto for 90.00 +/- and it took me 12 hours.
not terrible, just involved job.

that is the how to i used, great detail...even has a tool list.

good luck.

 

i paid to get it done since it was in winter and i didnt have time.
costed me 600$cnd. including 7hrs at 65$/hr. the rest is gasket kit, shop supply and coolant/oil change.
not too bad but get it done soon or it will cost you an engine in the next couple months !

 

Yeah that sounds about right. Make sure you flush your system a few times over the next 6 months. There is probably alot of rust in the system from that.

 

Thanks guys. The sad thing is I just spent $45 to do an oil change two weeks ago. And coolant flush over the summer. Bad timing, but whatcha gunna do, ya know? I'll be back if I get lost in the process. I'm gunna have to try to do it myself.

EDIT: I'm assuming this kit will do?
