hi, my name is XXXXX XXXXX i'll be happy to help you with this today.
because its a diesel poor compression in that cylinder could also cause a knock, basically the same thing as a bad injector.
wrist pins and main bearing tend not to cause knocks.
rod bearing do.
a bad injection pump is also a possibility.
if you crank #1 and #2 injections lines does it go away?
no when you crack the injector (1&2) there is still a nock
We have it in a shop now, they will pull valve cover off, and check the nock. Maybe in the valve assemble ?
then they will look at the bottom end. (crank & bearings) . Got any ideal cost of a reman. short block?
The lift (hydraulics, transmission,paint etc. is in good shape) I bought it right and can afford to put some$$ in it.
The lift is not big, single front tires, 4000 lb lift. Also with a nock, there's lack of pulling power.
