Cam sprocket washer cracked
I read in some other post long ago about ballade sports tensioner. I installed it and heard a squeel took it off and i still heard it so i assumed it was the accessory belt. Come to take the valve cover off and find this. I read billman saying it would sheer a cam bushing off if it squeeled but idk what that was referencing to. Is this it? Should this be changed? It looks bad... Lol. Ive been hearing some loud metal sound at 8k rpms i figured it was a shifter needing a regrease but this looks terrifying. What do you guys think? This is a daily driver with 117k on the odo.

That is not cracked. It is the normal surface of the washer. If you are hearing squealing after a TCT install, the chain is likely overtightened, and the noise is the camwheel bushing being chewed up. If it is allowed to continue, the entire engine will fail due to complete loss of oil pressure.

Kinda on a low budget and the oil bolt inside two other oem units i had are stuck tight in it, i had two ballade sports tct and screwed one up mixed up bolts and over torqued it. I have a good used ballade sports one kept the worm gear inside n put the oem springs in. It no longer has the high pitched squeel like it did before and it fit snug. But i do hear a wind up from 1st, im imagining that is just the serpentine belt? Or do you think the damage was irreversable because i drove maybe 100 or 300 miles with the chain over tightened i think, im surprised it did not snap.

Also could you elaborate on the cam bushing? I dont know if i missed it in the helms manual but i dont remember seeing anything that says that. I am confused as to where that is.

You think it might be a good idea to get it replaced? Can you do it without removing the head? Just unload the tension and hold the gear with shop towels under to catch the washer?

Yes OEM calls it the idler. It does not spin on the bolt, it spins on a thin brass bushing.
Camwheel removal requires camshaft removal, and TCT removal. Head removal is not necessary.
