Read carefully. I said intake manifold GASKET.Eric,
Only the upper half of the intake is plastic, and no coolant in the upper half. That plastic portion of the intake houses the FI spider.

Aside from normal parts lifespan, did the TBI 350s have the same failure issue with intake gaskets as the vortec?
I’m tentatively looking at a 95 Z71 for my son. It has 140k on it.
They fail after time, the failure is caused by the aluminum intake manifold expanding and contracting at a different rate than the cast iron cylinder heads. I would plan on changing the intake gaskets IF you by the '95 for your son. I would consider it good preventive maintenance.
I suppose it's possible could be a bolt or cracked flywheel would be better then a main or a rod, or toque converter.My truck is a 1993 1/2 ton 4x4 with a 4.3 v6 it has developed a random knock its quiet at start up it mainly does it under light acceleration but its alot louder than a spark knock I have narrowed it down to the area of the flywheel inspection cover or the oil pan with a mechanics stethoscope.
Now I have heard these engines had a problem with the flywheel or flywheel bolt that give off a rod knock type sound does anybody here have any other ideas or have heard of this type issue with the flywheel?
Cast iron intakes were bad about leaks too.They fail after time, the failure is caused by the aluminum intake manifold expanding and contracting at a different rate than the cast iron cylinder heads.
