Hi,
Problem with my grand Cherokee 2000 with a 4 liter.

I had a problem with one spark plug, the inside drop in the engine on the high way.. I replaced all the spark plug and start the engine I’ve noticed a valve problem. I removed the head and replace 1 valve and at the same time changed all the lifter hydraulic du to other problem with them . I start the engine and run well.

But a week later the engine have started to knock or a tap.. That more noticeable when the engine is in cold condition and when the engine got warmed I can hear a little bit the knock and if i play with the throttle i hear it from the top but not sure

really hard to pinpoint

so what do you think about it?

thanks
