Hey guys im new to this website just signed up last night and it looks awesome so far so ill give er a try! Ok so i adjusted my valves a while ago to .010 and .020 cuz i dont think they have been for a while and the trucks got 225k on it and it seemed to run louder than a couple of other guys trucks i know in the area and a little rougher? So I read some more on how to do i and say you can put them at .008 and .018 so i tryed that and it quieted it right down and seemed to run a lot better then before. Is there something that could be wrong or is this normal for an engine with higher miles?

I don't think so... 225K miles is LOW miles really... you might want to talk to CajFlynn (closing in on 800K miles 2001) and then talk to Taz (630K miles on a 1992)...

As for the sound of the engine most of them have quite a bit of clatter which is normal for most engines... As for the -.002 on the valves I know a few that done this and its still with spec so I'm rather sure there is no ill effects of being slightly tight.

Alright thanks a lot I wont worry about it then. I just get a little peranoid about the truck sometimes lol dont wanna screw anything up is all
