Re: clevo tap tap tap noise, checked lifter's
7 HEAVIN when the engine was rebuilt recently were the roller lifters replaced? From experience it does not pay to run them for any longer than 2years or 2000k, whichever comes first, and then u are on borrowed time especially if the rocker gear is not backed off when the car is not in use, valve springs will need checking and replacing/ shimming regularly as well of course. Hopefully i am wrong, but a lifter wheel bearing may have failed and smoked a camshaft lobe causing the tap,tap noise. Mechanical rollers are great in street cars but if u dont keep up with the maintenance they will bite u in the bum everytime.
