Starting my 99 pontiac grand am
My car overheated and blew a head gasket .
We were't sure if the block was cracked or
not. We bought this sealant to fix cracks in
the block and head gasket. Apparently
some sealant made it thru the crack to the
cylinder. That caused it to not fire and now
worse yet I believe the sealant may be
curing in the cylinder too. Any ideas on
why the starter is not working suddenly?
