Ok, Back story is i was headed to work on the highway came up to a hill and randomly the truck downshifted and the dash lit up like a Christmas tree with flashing engine light and all the normal other lights. It still ran but only at certain RPMs and once down at idle stumbled and hard to get going. Kinda felt like it was running on 4 cylinders. Since nothing was knocking and i was only 3-4mi from autozone and home off i went to get the codes read.
Outcome of the code reading was primary code P0021 Bank 2 timing over-advanced or system performance. Also with a gang of other codes but the other associated P0018 Bank 2 crankshaft to camshaft correlation. Guy at autozone proceeded to try and sell me a timing belt.... the car is F---ing running still. thanks bud...
Get her to the house and proceed to check the timing by opening the cam covers and this is what I find the Right bank #2/passenger side is 4 teeth off!
So proceeded to rip it apart like a timing belt and cant find anything except this slightly greasy stuff on the gears and the belt pretty slick.
I think it was from spilling a bunch of coolant when i changed out the water pump outlet gasket earlier in the week due to leaking. it got all over the belt and then 3 days of running i think the glycol in the coolant reacted with the belt friction and made this greasy solution. So 6hrs later all cleaned up and belt and gears with cleaner and what not shes back to running like a kitten.
Figure this would help others as the few posts on this subject noone ever comes back to say what the fix was.
