Where is 235 hydrolifter air bleed groove tech tip? Or any excelant info about quieting a 235's valvetrain.

Thanks

if they're really noisey yu'll hafta clear the oil line feeding upstairs then adjust'em. pull the valve cover and watch when running, and yu'll probably see -> little oil gettin to rockers. also I've always had old mechanics tell me ya hafta hear the valves on any old chev 6 or they're too tight.

It is a fresh full rebuild. So much oil pressure I can't run the motor without the valve cover witout oil getting everywhere.60psi under any load and no less than 30 at idle. I have to drape a rag over the rockers to catch to oil spraying out of them. Howard cam, double wound valvesprings,62 motor,bored .060, ati superdamper,balanced, pertronix ignitor, s.s. valves, hard seats,alum timing gear,clifford intake, edel 500 4 bbl.,repo jet hot coated fentons,all in front of a turbo 350 with a gear vendores overdrive behind that. Goes 100 mph at under 3000 rpm. Anyway, I need to figure out this noisy valve thing.

Yes tc Thank you very much. So frustrating to remember reading something and not be able to find it.

100mph under 3000rpm
What do you have for brakes and suspension???

Do you have pics of this ride

When you adjusted the valves did you find zero lash and then give the adjusting screw 1 1/2 turns tighter? With that much oil coming to the rockers I doubt there is any air getting to the lifter. I had a 1956 Chev. with a 235, one time that would have a bad valve noise after it got really warmed up on a hot day. I found out what caused this was the bore where the lifter ran in was worn just a little and when it was really warmed up there was too much clearance around the lifter for the oil pressure to pump the lifter up. I ended up putting in a solid lifter in the bore and adjusting the valve with the proper valve lash. It was that way when I traded it off many miles later.

I can imagine the surprise of the next owner when he found that.

I just finished removing the nipples from a few of my rocker adjusters, and am about to set all the valves at 3\4 turn past zero, and see what happens.I have mustang II front susp. with 11 inch camaro calipers and rotors. **** nine inch rear with 3.50 gear. no pics online right now, I'll work on it.

thanks for the replys

3/4 turn is good enough.

Patiently waiting for the results

I put it all back together with a new bigger fan, no more hi temp at low speed. I diagnosed a definite exhaust leak, and tightened the adjuster screws about 1\8-1\4 turn past contact with valve. Any farther and the valve starts to open up. On #4 exhaust valve the lifter seems a litlle spongey. After tightening to this loose adjustment, I fired it up and two were still noisy so I shut them up with a 1\4 turn more and now can't hear anything over the exhaust leak, So I think cleaning up the adjuster nipples helped. After I fix the exhaust I'll be able to hear better. Thanks for the help.
