Bad Lifters? Please help..
The engine is making a tapping noise when cold, it goes away after the engine warms up. Its coming from the passenger side head, it sounds like a bad lifter or something, I dont want it to damage my cam or anything by driving it more..but as of now I dont have the cash to pull everything off and replace the lifters. The lifters are brand new and I believe they are still under warrenty, but since its an only vehicle rite now, I cant pull it apart and work on it.
So my question is, will it hurt the engine or anything if I drive it? I never drive it while its tapping, I always let it warm up before I take it anywhere. When I changed my oil at 500 miles, I used 10w 40 and some lucas oil hoping it would fix the probelm..obviously it did not. So will it hurt my engine or anything in the head if I drive it this way?
The engine a freshly rebuilt 1999 4.6l 2V with only 500 miles on it. Just did the first oil change.
