This one's an 03' 168k. My friend melted down his 4.7. Got him a used one
(75k). The used one had a broken timing chain guide. I put in new chains,
guides, tensioners, and oil pump. Now it's ticking. When it starts, it runs
good. Good power. It threw me a cam out of time code, then a crank out of
time code. I rolled it through by hand, no problems. still ticking. I build old
school GM, don't have much experience with newer Dodge. About to put
another set of chains in it. HELP.
you bought a used engine without hearing it run- you threw the dice- sometimes that works out-
There is something you can try that worked for me when I had a tapping in engine add some Lucas Engine Oil Stabilizer. If you do decide to try it remove same amount of oil as on the bottle of stabilizer. Like I said no promises but it is worth a try.
Did you install the chain one tooth off?
The engine came from a bone yard I have used many times in the past. Never had any problems from their engines before.
