Then the icing on the cake would be a rare dampened V-Belt Crank Pulley to make that motor run as smooth as my wife’s homemade whipped cream.

If you have the timing chain cover off, check the chain slack. All diesels are interference engines which could be damaging to at least the push rods. Not that timing chains fail, wear in the set will let you know when to change.

I've seen and replaced failed dampers. The level to which you're going to tear it down, you'd be better off replacing it if there's any doubt. Also replace the front main seal if you replace the damper. Check timing chain for stretch while it's apart as well. (Doubt it's a issue, but you're there, only take another minute to check) And I'd advise new belts and hoses while you're in there. Again, to the level you're going to tear it down, it only make sense.
Definitely will do all of those things. I would much rather replace items while the engine is tore down. Thanks

For a few dollars more, you could easily upgrade to a higher flow Flowkooler water pump. Just give them a call and tell them what you need.


Here’s a good write up on replacing the timing cover, water pump etc I did not long ago. Starts on page 5 close to the bottom. Might help you out with getting a super clean install. It it crucial to have the threads super clean and to apply a generous amount of RTV on the bolt ends. Especially on the 2 water jacket holes on driver side of the timing cover and 2 smaller holes below the harmonic balancer.

Ill be calling thm for sure. Ill update y'all on what I find out.
