Ok guy's I just replaced my fuel pump in my 2001 limited edition trail blazer 4.3 which went well but after getting the truck running I put it in gear to drive and it shook a little then cut off then I noticed it had ran hot in a matter of minutes. I popped the hood and checked my water and anti freeze and it was dry...My friend checked my oil and it looked like coffee with heavy cream! My friend think's I have a blown gasket some where but I can't really afford to get it fixed. My question is can I use a gasket sealer to fix the problem and if so which one is best to use?

 

That stuff doesn't work, you would just end up clogging the radiator.

Most likely a head gasket change is what you're gonna have to do.

 

Like you guessed, Could be a leaky intake gasket, more common than a head gasket on these engines. I would take the top apart first and check intake for leaks.

One caution, if you drive it like that you will destroy the bearings in the engine. You must change the oil if it is milky.

 

But will the sealant work bromanjr

 

My opinion, no, the gaskets fail completely, they cannot be re-sealed, they must be replaced.

 

ok thx

 

hopefully it was intake...not that terrible of a job, just takes all day or so if you doing it yourself. it took me 12hrs to do mine. was well worth the cash i saved vs paying for the labor.
