Just curious, but has anyone seen these valve covers on a factory replacement engine? Warranty indicated truck had complete engine replacment in 12-94, and last partial replacment in 1996. I bought this truck from a dealer who got it from Tim Knaebel in St. Pete, Fla. Tim told me he has never been inside the motor, or replaced the valve covers. Casting numbers on head indicate stock LB4 heads, just curious about valve covers, as every stock or replacement engine I have seen posted has the steel valve covers on it. Currently doing a vortec, cam, and injector swap.

Re: valve covers

Just FYI, but casing number on heads is 14099067, which a search from the vault indicates stock Sy/Ty.

Re: valve covers

Those Valve covers didn't get put on 4.3's till 95. If it was a Steelership that did the work, then there is no tellin what got replaced... There were some 4.3 1994 TBI's that got some of those heads. but mainly those were the 94 pick up trucks and not the first gen blazer/jimmy's...

I have pulled sets of these plastic valve covers off of 3 1994 Blazers/Jimmys......two of the three were green.(not that the color has anything to do with anything, just remember the details of the trucks)

pulled the lower intake off today, and the block has plastic lifter retainers. Apperantly, the block is a 1994 replacement. Truck has run great, so still don't know what negatives the 1994 block will present. Still moving foward with head, cam swap. we'll see what happens.
