1995 4.3 v6 water in back 4 cylinders wondering if it is head gaskets or

Intake leak puts coolant in oil pan 99% of the time!!... Unless it got hot and warped/cracked the heads.. I have no clue at this point... Would like to know what ya find!

How long you figure to pull heads and repair. 2 people working shop full of tools.

Can't really say how long..... It depends!..... It ain't a bad job... It's basically a Chevy Small Block 350 with 2 cylinders chopped off... Same old 'bulletproof' engine they have had for years after the intake is removed!!!!... Better check compression and maybe air check the cylinders before a bunch of work... Didn't know you had the tools and a shop... Now if you have ever worked on a Chevy SB then it should go pretty smooth!.. These engines are pretty tough... Don have to work on em much!!!... Check out the intake and gaskets once removed... It's possible!.. **FIRST** remove the rad cap (air check cylinders with rocker arms 'loose' or removed to find out where the air goes)!!!! Need the proper tool for this!... Can't just use a blow gun! Good luck!

Some more news. Filled up radiator fluid drained back into cylinders while the truck was off

Yes I'm sure it did without any repairs!!!

Took off intake gasket blown out all over

You good... Fast too!!!!
