Hello, I just finished with my diagnostic and adjustment procedures. The lash was very tight on 3, 5 and 7. There were others that were tight, but nothing like the down cylinders. Compression test following adjustment increased #3 from 90 to 110. #5 from 100 to 110. #7 went from 120 to 130.
There is more valve tickin on start up.
The timing did not change.
I then checked for combustion gas leaks and did not detect any in the radiator while running the motor for 2
mins. Head gasket is OK.
I then topped the oil off with a can of Rislone and put some MMO in the gas tank.
I am going to cross my fingers but I have a good lead on rebuilt 1557570 heads to replace mine. I will refurb mine and keep them on the side.
Anything that you guys think that I missed?
Thanks again,

You do not need heads, or anything else but gas & oil. That car is now good to go. Let us know your Studebaker driving impressions after after you complete the first 1000 miles, then the next 10,000 milesLast edited by JoeHall; 06-13-2016, 07:28 PM.

I had to google Davis, Ca. to get a sense of where you are in the vastness of California. Just to confirm the adjustments you've made, and, assuming your other tune-up specs are correct, why not button every thing up, and hit the road for a lengthy workout. Interstate 5 up toward Willows, or any other interesting stretch of highway. You seem to be ideally located for interesting choices for any direction the compass points. Give 'er a good romp and let us know if her attitude has improved.John Clary

I just found this thread. Glad to hear you found the trouble to be an easy fix. I've always found that the Studebaker V8 seems to like robust driving. I would not abuse it, but don't baby it either. These early V8s don't respond well to lazy driving. It causes carbon build up and sludge in the oil. Spirited driving will keep the engine at a happy operating temperature and good amounts of cylinder pressure will help prevent carbon.
Now, do your duty, and spin the tires and do some donuts in the nearest parking lot. Just kidding of course.
BTW, we were just in Davis a couple days ago to have Woodstocks Pizza. The best Pizza joint in the world.sals54

You might also want to recheck the valve clearances after they have had a chance to re-seat themselves. The ones that were out of spec might drift for a while, or drift more than the others.
BTW, I always consider a ticking valve to be a valve that's not burning, so a little lifter noise doesn't bother me.RadioRoy, specializing in AM/FM conversions with auxiliary inputs for iPod/satellite/CD player. In the old car radio business since 1985.
