Default Re: Hydraulic Lifter Preload Trouble on 68 289

Guys,

Many thanks for saving me the grief of learning this the hard way. I see now why you recommend to loosen the nuts a bit, run the motor to get oil pressure back, then start the adjustment process to find zero lash. Sounds like it will take a couple hours to go through the process properly. Need to make sure the wife doesn't have a long honeydo list first....

Just to be sure:
The above procedure is just to get to the zero lash condition. Once this is established with reasonable certainty, I assume everything gets adjusted an additional 1/2 to 3/4 turn tighter to put the lifters somewhere within their adjustment range. If so, this would agree with rwhite's comments.

@Rev: The lifters are absolutely hydraulic. Stuffed them in there myself way too many years ago.

@rwhite: Yup, stud mounted rockers. And yes, I'm tired of messing with the car and want to spend more time actually driving the thing. Thanks for the rocker position tip - sounds foolproof.
