Aftermarket cam tensioners

[MikkiJayne]

Hi all,

Has anyone used the aftermarket cam tensioners for the 40V? I just got a price of £478 from TPS which is totally untenable, and unfortunately our hosts don't have any used ones at the moment.

Background - lumpy idle, CEL for cam position sensor, compression 10-11 bar on 1-4, 12-13 bar on 5-8. Opened up the cam covers to see the 1-4 bank tensioner jumping up and down when I rotate the engine by hand. Seems that the top of the tensioner is loose and the bottom is locked solid so the chain is slack and the inlet cam is jumping around.

Very at the moment. I don't want to spend £1000 on tensioners to find there's valve damage, but very wary of putting potentially crappy Chinese bits inside the engine.

Thanks
MJ
