Valve seals

[Preston]

i know it’s a easy fix just pull the valve covers and pull the rockers and replace the seals, just have to hold the valves up either with rope or air. My question is has anyone had any luck with the products in a bottle, I’m sure my problem is because my truck had been stored for a couple years and the seals are brittle, but I thought I might give it a shot, just waned to throw this up in the air and see what happens. Thanks

If just recently started running, might just need to let it run for a while. But oil additives are unlikely to fix valve seals if they are leaking.

Nope. Bite the bullet.
