I was replacing all my gaskets on the 98 S10 4.3l automatic with a Felpro head gasket kit NAPA sold me.
After all was done and put back together, got into the cab and prayed for a startup.
Instead it tried to turn over for about half a second and came to a clank dead stop.
Heart fell out of my rectum.
So went through what I call a process of elimination. Check the battery, all serp wheels, starter, distributor timing, all was good. Nothing was seized..
Except for the crankshaft, I got under the truck and put a socket to it and it would not budge clockwise at all but will turn counter clockwise no matter how many times you turn it.
I never disconnected the transmission or took off the oil pan, or even removed the timing chain cover and made sure nothing got in the lifter arms where the air intake sits.
I did have to reset my distributor timing to TDC and only turned the crankshaft clockwise with the heads on after replacing the head gaskets and it turned fine with no issues at all with the lifter arms installed and intake manifold.
I repeat, all serp belt pulleys spin just fine, nothing is seizing and would cause the camshaft to not turn over because of the serpentine belt.
Does anyone one know what might be going on, maybe can point me on the right direction to finding out, or ideas before i got to take it all apart and restart?
It has 130k miles on it and was running just fine with the occasional thrown code for a misfire witch what made me want to do gaskets.
