Anyone know the size of the harmonic balance bolt on a Chevrolet Silverado 4.8 because I'm removing and replacing the valve stem seals?
What's the correct section sir?Got this posted on the wrong forum section bud.
But to answer your question, it should be the same as the 5.3 (16 MM x 2.0)
Thank you sir!Haven't heard anything about them. Used them on the Saab when I did the DOD delete and reconned the heads. No problems here.
Felpro makes some good stuff as far as gaskets go if you don't have OEM.Are fel-pro valve stem seals any good?
Thanks a lot!Felpro makes some good stuff as far as gaskets go if you don't have OEM.
