Question about 1990 Chevrolet S-10 Blazer
I have a 1990 chevy s 10 blaver 4.3 liter
it was over heated due to a bad radiater line we fixed that and changed the thermostat when doing a compression test the first five cylinders red at 60 but the sith red at 90 and then back fired it is just poring out gas at that cylinder what would caus all the above with the cylinder how can it be fixed what do i do
I agree with fixincars. Once you overheat an engine you take a really good chance of having a blown head gasket or warping the cylinder head. Vortecs are bad once they overheat. You have 2 choices, you can take yur heads off and spend the money and have them checked or you can just buy reman or new heads and get it completely out of the way. Of course there is the junk yard but there you are taking a big chance of wasting money and having to do the job twice.
