Simple... It's a 5 speed transmission. Just stick in 5h gear and set the parking brake. An automatic I would get creative with a wedge or strap on the front pulley. Make sure you report all your c

The cylinder that is sizzling/gurgling is the one I'd expect that is not firing quite right. It's probably 'wet', and that 's what you're hearing. Wet from fuel, and not oil. Now

Alright guys I am experiencing a miss at all RPMs. It is pretty noticeable near the engine with a knock, but is extremely noticeable at the exhaust. It is easy to feel that the exhaust is "puffing" per say. Now I just replaced the injectors with a new set of 125hp sacs, but the miss was prevalent before the injector swap. The swap did not make a difference. Everything sounds the exact same as before the swap. I have fuel squirting out of each connection at the cross over tubes while running.
MoparMan and I spoke on the phone earlier and have decided to take a systematic approach to resolving this issue.
Ruled out: 1. Injection pump: Always supplied good pressure, less that 10K miles and miss seems to only be in one cylinder. 2. Injectors: Swap made no difference.
Possibilities (Almost endless): Burnt/ broken valve, broken piston or piston rings, clogged cross over tube, valves way out of adjustment
I should receive the truck Friday from being painted and I can start diagnostics.
The plan: 1: Pull valve cover and quickly check valve lash - just make sure somewhat close to spec. 2. Use an infrared heat gun on the exhaust manifold right were it come out of the head to try and narrow down which cylinder is missing. If that does work I will pull the cross over tube and replace it (I already have 1 new one that will ship out Monday). If that does not fix the issue I will do a compression test on that cylinder to determine if it is the bottom end or the head.
If the heat gun does not find a "cold" cylinder I will pull all injection lines and cross over tubes, then clean each tube and try to determine if there is debris in one of them. If I can not find debris in any of them I will replace them with the new one, one at a time. If that proves inconclusive I will perform a compression test on all 6 cylinders.
If any of the cylinders are low on compression I will pull the head and determine what is wrong internally.
Any suggestions on the procedure or something else I can do to diagnose what is wrong with this thing??
