Hi Ben, My name is***** will be glad to help. Clatter/Rattle from the upper end and timing cover is not a good sign. Check and verify the overhead and injector settings and timing is correct. If so the look for a potential bull gear failure occurring. Let me know
it is hard to say not hearing the noise but either way you wil need to retrace your steps and the most common possible thing to look for is the timing slightly off and if ok verify the injector height settings and overhead adjustments..... Click on this link Let me know
Valve and overhead
Just verify the cam if changed is correct as well. It is possible also to be off a tooth...
Yes the front timing cover has to be removed.... Look at PDF page 36... I believe yours is likely older than the models with the compact gear as in the manual.... Im off for the night. It is after 2 am... We can follow up as needed.
Its called a restricted orfice and it is a 90 degree fitting at the rear of the head the return line connects to....
Ahhhhh yes that could do it. Its a pleasure to help
