i have a 92 s10 blazer 4.3 vortec that has a blown head gasket and im asking for good tips on tearing down my motor, what i should look for or clean well, putting back together? i've ordered my parts online and should be here tomorrow, so im tearing it apart tomorrow nite, taking heads down 2 shop to be checked and valves done friday morning and hopefully putting it back together saturday nite so i have time in between to some xtra on truck, any good advice???

 

how long has water been in the oil? or how long have you been driving it this way? id worry about the lower bearings etc if its been setting or driving it with water in it.

If it checks ok,just do the typical stuff like cleaning the surfaces really well,and stuff some rags under the lower intake to keep stuff from falling into the engine. Pick up a few gallons of some cheap oil from the dollar store,wally world etc and a few filters.Change the oil and filter,Let it run and check for problems. then after you let it run for a few minutes change the oil and filter again,drive it around then change it once more. Maybe this is overkill but you wanna make sure no water etc is left in the engine. Its worth the insurance.
