Need this answered ASAP please....
Im doing the vavles on my hyd. flat tappet truck. I set the lash, I twist the pushrod between my fingers until I feel a slight tention. Thats zero lash, then I go another 1/4 to a 1/2 turn after that to preload the pintle depth on the lifter.
Well, my question is after I do that. Should the pushrod still be able to turn or should it be tight? Because they still feel lose to me...and the rocker still has some play aswell. More than I feel it should.

The short answer is no. If you're going through and adjusting valves and then going back and finding them loose, then your adjustment process is not correct in terms of positioning the engine for each adjustement.
I use the companion cylinder method and it's worked for me for quite a while. Easier, faster and significantly less error-prone than the factory approach. I say this with caution, as I believe in doing it "the factory way" - but I've been converted. Somebody's sure to pop up and say how wrong I am, so you'll have to make your own evaluation ![]() BTW, 1/2 turn or whatever the cam manufacturer recommends. No more, no less for a street engine. Confirming that this is for a GEN I SBC, correct? I have a PDF, but it's too big - here's the basics:
