Re: Valves/ Id and adjustment
First of all, do not run it any more until you figure out what the problem is. If it is a mechanical cam, and he adjusted it too tight, it can hold a valve open and burn the valve. Take off one of the valve covers and turn the engine over until one of the valves starts to open, it does not matter which one. Mark the pushrod somehow so you can tell if it moves up or down. then let the engine sit for a few hours and see if the pushrod has moved down any. If it has, it is a hydraulic cam. A hydraulic lifter will slowly bleed down from valve spring pressure, a solid lifter will not. If the pushrod does not move down any, its probably a solid cam and you need to put some "lash" back in the valve train. If you do not feel comfortable doing this, find a "real" mechanic that knows how to properly adjust valves and let him look at it. Anyone that does this regularly should easily be able to tell you if it is a solid cam, or hydraulic. If it is a solid cam, you will have to guess at the adjustment unless you take the cam out to find a number.
Ift would help if you tell us exactly where you are located, someone might be able to recommend a good mechanic in your area.
Hope this helps,
