Someone told you a line of bull, Lifter get oil, if the oil pump is working, but the springs inside the lifter can fail. It will cause a ticking sound under the value cover. But the lifter isn't what you hear. The rocker arm has alot of play because the lifter isn't doing it's job. Pull your value covers and look around Be sure all the pushrods are making contact with the rocker arms. Rotate the engine and check them again. If you find one that has excessive gap, check the push rod. Be sure it isn't bent. If it seems ok, you will need to tear down your motor farther.I HAVE A 88 s10 with a 350 in it i think one if not more of my lifters isnt getting oil how can i fix this?
You can try an engine oil flush but this doesn't work all the time, If it doesn't then you will have to tear down the engine.. Sludge build up can sometimes be flushed. There are several brands of flush available at the auto parts store.. or you can try putting a quart of transmission fluid in your oil and let your engine run for about an hour then change your oil and filter. Transmission fluid has a heavy concentrate of solvents which keep the sludge from building up in the trans. Careful though,, if it's left in the engine too long it can deteriorate O-rings and gaskets Good luck
