Check out the a selection of camshafts for different types of engine use. Hydraulic, Solid and Roller cams and lifters. The camshaft is the brain of the engine, so enusre that the correct cam is choosen for your engine.
With so much metal debri though out the engine Would you recommend getting a new engine? ...or just replacing oil pump timing belt other components work?..where does all that metal debri exactly go? Does it All get flushed out after changing lifters and camshaft or does some of it stay inside small crevices Creating potential future problems ?
The lub is not the problem for a new cam going flat. Take a new lifter wipe the bottom off drag your finger nail across it take a pencil and drag it across the lifter you can feel the file as it is filing the lead off of the pencil along with your finger nail. A ground surface is a poor finish. Now take a sheet of red crocus cloth and a old phone book or soft back book `put the sheet down face up. Now take the lifter an rub it in all directions tilting it as you go (a lifter is crowned) until it is smooth like a piece of glass now run your pencil across it it is now longer a file and will not file your cam lobes down, a new lifter is a file. Without doing this what happens is after a cam is run softly for a while, (without polishing the lifter) it finally wears the grind marks off off of the lifer. If you are running real heavy springs a lot of racers will pull the inner spring out to cut the pressure on the cam lobes. When resizing con rods leave the bore 2/10 under sizer wrap crocus cloth around the mandrel then do the pencil and `finger nail test, now you will not have bearing material transfering and killing the oil clearance. Think about this crank shafts are polished after grinding. Me, a long time machinist in large machine shop doing ship repair, paper mill, mining equipment, saw mill, and a GT1 road racer driving a Camaro . This something I have just kept to myself over the years. Have fun, Don
