I remember this being addressed several months back. At the time, I was getting ready to purchase new lifters and kept the metal shaving theory in the back of my mind. Some people laughed at the ideal of taking new lifters apart to clean them. I can now say after today that the theory is correct. New Crane lifters that had tiny metal pieces inside them stuck in the light coat of oil. 2 former mechanics were in my shop laughing at me as I started taking new lifters apart. Told me I stayed on this crazy board too much. They shut up after seeing the second one with metal in it. One then helped me clean them for 30 mins. Well worth the time!!!!!!!!!!! Thanks guys.:bglasses:
John I thought people were still have problems with them imports even after cleaning. o No: I have a set and was afraid to use them, and bought the new ones TA was selling that were the Same as the buick design in the early 70's.:TU:
Yep, found this in my new Isky superlifters from Postons in 1988. I got some goofy looks while taking them apart too.
I was told to buy the chevy lifters and they would be fine. I haven't yet, but when I do I will take them apart also. They are of course .100" shorter, the cup is lower.
Hi Guys, After years of doing this and finding "crap", no matter who's brand or manufacturer, I thought my fellow Buick brothers deserved to know!:TU: Just to be fair...there have been sets where only a few of the lifters were contaminated but for the most part the majority are. I just will not leave it too chance. BTW...I have found "junk" in other makes (Shivvie, Ford, ect.) lifters too!
My lifter horror story has to do with Oldsmobile. Upon firing it for the first time, I broke in the cam, but could NOT get one lifter to quit clicking. When I disassembled it, there was a check valve missing. It could not pump up. The cam company stood behind it, and sent a new cam and set of lifters.
