Hey!! I have a 88 GMC 1500 4x4 I've just recently had the heads an all the gaskets replaced but the guy said the valves still need adjusted a little more so I'm trying to figure out how exactly I would go about it?? I've been told to start it w/ the valve covers off an the truck running but not so much more detail the turn here an turn there. Honestly I'm mechanically declined when it comes to the inners of a vehicle. Any advice will help. Thanks!!

Well to start with ...."the guy" who did the repairs should have adjusted the valves properly before he got it back to you. You don't send it out telling the owner that the valves need adjusting a "little more", they are either adjusted or they aren't. Since you're not mechanically inclined and therefore can screw up the valve adj. procedure I would take it back and tell the "mechanic" to finish the job.

First, you need to find out if the the engine has hydraulic lifters (easier to adjust) or solid lifters (harder to adjust and requires adjusting every 3,000 miles or so). Assuming this is the original 88 engine, they should be hydraulic.

Here is a page w/instructions to set hydraulic lifters on your SBC engine.
