Looking at a low mileage (79,000 mile) 1995 Chevy 454.  I had a 1998 Suburban (103,000 miles)with the sorry nylon shaft guide on the oil pump shaft.  Nylon split in 1/2 doing 75 on the Interstate.  By the time I got over to the shoulder the engine was toast.  My question is ....What year did GM start using the nylon shaft guide?   If the '95 has the nylon, I'll drop the pan and replace it before I put in on the road.

It will have one. Replace the intermediate shaft with the steel guide version that is available.

 

What year did they begin using the nylon? A long time ago, first time I ran across it was in the 70's.
