Re: ¿ IS MY CAM OR VALVES SHOT?
Warm the engine up, then wire the throttle open all the way. Remove the coil wire from the coil. Now do your compression test. Record all four cylinders. Now, take a squirt type oil can, and shoot some oil in the cylinders. If the compression doesn't come up a lot, it's the valves themselves. If the pressure goes way up at first, it's the bores/rings. If the valves need to be redone, it's going to cost about $300 to do it right. As long as your at it, use the exhaust valves and seats out of a Tracker. The stock cam isn't that bad, the Isky torquer is a lot more lift, and better duration though. Get it direct if you can, it's cheaper. Ask them if you can use the dual springs, not sure if you can, gotta call them this week, I'll ask. By the way, if you have to change the guides, make damned sure that they get reamed out to exactly 7mm, not the English equivalent that most machine shops use because they are too loose! Any q's, let me know...
If it aint broke , I can still fix it...
