Blown Head Gasket or Cracked Block??

[DangerRanger37]

In the process of tearing the top of the motor down they found the intake gasket blown out and was allowing the coolant to mix with the engine oil. They did not remove the heads because they were very confidant the intake was the issue. They replaced the valve cover and intake gaskets, added all new coolant, flushed out the crank case and changed the oil twice. At this point it seems to have fixed the issue. Fingers crossed this was the problem and the issue has been corrected. Truck started a little funny this morning and died a couple times but once it remained running it has been. $635 repair is way better than new head gaskets or new engine cost. Thanks for everyone's help!!!

Just run a compression test to rule it out for Christ's sake. It's simple enough and should have been done BEFORE the intake manifold, as a diagnostic just to rule out heads/ gasket. There are documented cases of intake manifolds making chocolate milk, but that's more of a 4.3 chevy thing. On my '97 there was no oil flowing through the intake manifold at least I don't think (just coolant).

Look into it before you have another episode at least.
