The oil filter adapter started leaking and before I realized it the engine was knocking. I had to replace the engine. The same thing happened to my son's Chev. Blazer with the 4.3 engine. The shop we took it to had two other trucks with the same problem. They said they see this at least weekly with the trucks that have the 4.3 engine and the remote oil filter adapters. This is just one small shop in an average size town. It must be happening to tens of thousands of these G.M. vehicles, and G.M. should be made to correct the problem and reimburse people for the expense they have suffered because of a bad design that they continued to use year after year. I would be willing to pursue a class action suit if others would join in.

In talks with a local G.M. dealer this problem with the oil filter adapter system on 4.3 engines is well know to General Motors. They need to do the right thing and come up with a modification or fix before someone gets killed because of it. Oil leaking from a ruptured line could spray onto the exhaust system in a number of places and cause a fire or the oil could spray onto the left front tire and cause loss of control.
I have replaced the seal in several s10 trucks/suv's and have it down to a art. For those who don't have a lot of money and hate paying the dealer rates the seal is not a big deal to change and all I have ever used is a used oil filter seal it is the same size and they are normally nice and soft already.
I have a 1991 S10 blazer sitting in my yard that my 18
year old daughter was driving and the filter adapter failed and lost all the oil before she could get it stopped.
The motor has over 100,000 miles and I drove this truck for two years, but now I can't even find an adapter to replace too bad one?
