There was a fair bit of chain slap and rattle just before i did the tensioner, so was thinking it possible slipped a tooth.I will start with the simple things first tho. Hopefully will sort the problemIts unlikely to be that from changing the tensioner. Simple things first. The position sensor reads off the cam sprocket, so its likely to be that. Engine mount is 5 bolts. and quick to whip off.
To check timing you need to remove cam cover, and on the cam tooth check that the gold link on the chain is lined up with the timing marker, and then you have to check the two links are lined up on the crank sprocket, which involves left side of the engine off.
I believe you have to remove the oil pump and rocker cover, you have to line up the marks on the cam sprocket and crank sprocket with the gold links on the timing chain. I attempted to re time mine but couldn't get the crank pulley off (the tool i bought was shit) it ended up going to 1320 for a rebuild (due to burning oil but thats another story)Sorry to piggyback off this thread but I didn't really want to start yet another Timing Chain Tensioner thread!
Basically my girlfriends R52 has started making the death rattle.... 2 weeks ago.... Of course it slipped her mind to tell me something was wrong until I got in the car and see the dash lit up like a Christmas tree and it sounding like a diesel.
I pulled the codes and got the following:
Basically a similar P0341 to above plus some rich running and misfiring - I've ordered a new tensioner and will get that fitted but I was wondering what would be involved in retiming and whether it's worth doing myself or if someone has a ballpark figure for what they'd charge to retime the thing.
Not sure you can just take the rocker cover off and if there is enough slack in the chain with tensioner out to adjust the timing sprocket to line up the mark with the back of the cylinder head whilst crank is at TDC (If that makes sense).
Or if I'd need specialist tools to undo the sprocket, take off the casing, oil pump out etc
Hopefully no further damage has been done :S
Any advice appreciated!
