A friend of mine has a 41 1/2 ton with a 235. He's having a problem with his hydrolic lifters. After running at 45 mph for a short time they start clacking. It appears that they are bleeding out. I have read that this is a common problem with 235s and hydraulic lifters.
What I'd like to know is if anyone has a solution (other than going to solids). Is there something we can do to the lifters to keep them pumped up? A high flow oil pump was suggested but I'm not sure that would work, and may blow oil past the rear seal.
We need some suggestions.
Thanks
George
