Last year I removed my intake manifold to have some testing and work done. When i replaced it .the adjustments were all over the place.Valve lash changed again after 20 miles. I found two lifters that I couldnot remove from their bores. I tore car apart to remove the cam. Two flat lobes. I held up those lifters with magnets. I stuck a magnet in cam bore and caught each lifter. they were mushrumed. Had to have engine gone through. All iron had been caught in
oil filter.
Oil pump drive was beginning to round. So new rings and bearings.new truck
oil pump (larger diameter drive shaft) cam , cam drive, chain and lifters.I installed the heads and rockers.Then I found that the center two rocker studs on both heads were pulling ,heali coils and all.I and the machine shop had not detected the studs being pulled.I had to remove the heads again and have the two center rocker studs repaired with inserts machined into both heads.
I have since gone off the original page and started other projects
Like trying to redo the fuel system larger plumbing and return,tank, pumps ,interior ,seats, dash,heater-defroster. Right now I'm stuck on getting the 5/8"alluminum fuel line from under the body up under the footbox heat sheilds(supply and return). I found that the alternater was bad and hardly putting out. Ive resealed the steering rack, had the radiator gone through, had many peices ceramic coated. new moter mounts.It just keeps going on.I don't think this summer is going to happen.
