Just wanted to say a big thank you to all for the information here. I have had to do a lot of learning about the lifters in a 235 hydraulic lifter motor. Had a couple of them that sounded like solids.
With all the information that I found here through the search engine and with the information from the car manual for a 53 at the old car manual project
I was able to take them apart, clean them up, preload them with oil. So far they are working just fine. The procedure in the shop manual was clear enough that I could understand. For some reason I missed that preload information here. Pretty sure I just overlooked it. blush
For those few that have never been to that site it is very useful for information that is hard to find. Everybit as much as Stovebolt.
