As you may reacall, 93 1500 350 TBI issues. Engine idle nice,
hesitates under load, poor power.
Well, I tested EGR and PCV valves, installed fuel filter. No change. I
got to thinking and reading that perhaps the valves needed to be
adjusted. I think th eduel pressure is fine. I trying my best to hold
off on dropping the fuel tanks and pulling the pump. I can here it
buzzing for two seconds when I turn the key.
So I adjusted the valves again. After the adjustment, the truck would
not start at all. What the #&@*?

valves again. Still wouldn't start. So I went to each valve and
loosened the adjusting nut and sure enough she started.
Here's my problem, when rotating the pushrod to feel the lash. I got
to a point where I thought there was no lash. I tighten the nut, wait
a while and I turned the pushrod just to check and sure enough,
there's still some lash left. I had to use a good amount of strenght

thought I'dtaken it all out.
It's not like that across all the valves, but a few of them sort of
So, should the lash be adjusted completely out of the push rods or is
some resistance okay before I give the nut one last 3/4 turn? I
obvislously had the valves tightened too tight hence the engine not
Do you think my valve adjustment could be the reason I'm not getting
any power and having hesitation problems. Valves opening to soon or
too late maybe?
Thanks for any help.
