Hi Troy I owned a motor bike years ago and I had the same problem, It would start off with a quiet knocking sound and get louder then suddenly stop but start up quietly again and again and so on which turned out to be the timing chain was worn.... SERIOUS mate. Good luck......
Hi here is a quick fix for the lifter tapping. Try adding 4 Oz. of tramsmission fluid to the motor oil , and run the engine for two minutes at 1500 RPM. This should quiet the lifter tapping.It works everytime i come across this problem.
Before you change lifters try this trick. Drain 2 quarts of oil from the engine and top it off with auto trans fluid. Let the truck idle for 45 minutes or until quite , then change the oil and filter. I have made many lifters get quiet this way and it will not damage engine.
those engines are known for lifters draining in order to restore them you must run the engine rpm about 2000 rpm for 5 minutes .they shoudld quiet down mitsubishi says to run them at 4000 rpm for 10 min,but i rebuild *** engines for 20+ years i dont recomend this with out causing damage to eng just hold the rpm to 2000 until the get quiet make sure you have fresh oil and the engine as good oil press
Sounds more likely to be a timing rattle rather then all the lifters at once making noise, if your EGR valve is bad this will happen and if the timing is off it will also do this, I can't buy the theory all 16 hydraulic lifters are noisey unless you over reved it something fierce, or ran it out of oil, or had someone loosen all the rockers.
the head gaskets are blown you can believe that anytime on any engine gas or deisel that you get oil in the radiator and there water/ antifreeze in the oil pan the gaskets and or cylinder heads are bad
