My 5.9 Magnum Build - Junk Yard Mule
I have had a 5.9 Magnum out of a 98 Ram that I traded a set of wheels and tires for over 8 years ago. It has sat in my garage ever since just waiting for an opportunity to live again. It is supposed to have come from a running truck with 80K miles. Fast forward, I have acquired an 84 Ram W-150 that needs a new motor. My plan was to tear down, use the long block, 1984 timing cover and accessories, an intake and a carb. I plan to use the existing truck manifolds, ignition and fuel pump. I did order a new cam, a Hughes Long Snout 208/214 @ .050 0.532/0.533 lift and their springs and retainers. I also got a new timing chain and oil pump.
I tore down the motor last night and it was not as clean as I had hoped. Some things that concern me.
· How much carbon was on the pistons, could not have been running very well.
· Lifters on #8 and exhaust on #7 would not come out still working on them. Motor turned over good so they are not stuck in the lift range.
· #4 cam bearing is pretty bad
· Timing chain worn pretty good
· 7 of the 8 plugs looked old but the plug on #8 looked really bad. Lots of detonation? What would cause this?
Attached are some pictures. Do you guys see anything that concerns you?
The cylinder walls still look great (still see cross hatching and not ridge). I plan to check the main and rod bearings. If they look good, I plan to change the cam bearings then put it together and run it. Is this a good decision? Based on what you see, is there anything else I should do/check? This will just be a driver and not a Mopar Muscle Truck (MMT). Lol.
