Valve Train noise
1988 Hydro Roller
Can some one refresh my memory, when the valves start to make noise (high miles), can we remove the valve lash on a hydro roller setup? If so what have you guys used on a stock setup? 1/4 turn past zero lash or 1 full turn past zero lash like the Comp Cams?

Yes, you can re-adjust your valve settings. I use 1/2 turn.
It might be possible that you have a lifter that is starting to go south..

If your 88 adjustment is the same as my 89,( which it should be) the Factory Service Manual says one full turn after 0 lash..."I would go by the book for a stock engine"... There adjustment of one full turn puts the plunger midway in the lifter....WW

I was thinking the same thing, might just order a set... Hate to get too in depth because I have plans for a rebuild in 6 months.

Why would you order a set of new lifters when you don't even know if that's the problem..It could be a lifter, rockers , a clogged pushrod... I would pull the valve covers and do a little checking before spending money on something you don't need....Lifters aren't that cheap, and sure not the easiest thing to install.....WW
