Chain Tensioner Bolt Washer replacement

Recommended Posts

Hi guys. Have a slight weep of oil from the chain tensioner bolts on my 2.7 987. Apparently a common fault as aluminium washers corrode out. 

So need to take them out and replace. Anyone done this and have any advice? Need to stop the crank pully with a 5/16th drill bit to block the crank/timing. Anything else?

Have you tried nipping it up a bit, sometimes works?

@Araf could this post be moved to the technical forum where it'll get more attention. It's not a "how to" post rather a "how do you'.

Did but actually made it worse. All done at my local garage. Fresh shell ultra in there, new filter etc so all good. £140 for two 71p washers lol. 

Sorry if I’ve posted this in the wrong area.

Seems like you have had it done, but you have to lock the cams and crank before removing the tensioner, otherwise there is a danger of jumping a tooth on the cam chain.

Hi. Yes, put an 8mm alan key in the teardrop shaped hole on the crank pulley to lock it in place. Didn’t lock the cams though. That’s with the flat steel shape thing that bolts to the two flanges right? Taking out the two plastic inspection plugs? Saw that done on a YouTube vid for an IMS bearing upgrade. Didn’t do that (not sure if needed for removing the tensioner bolts?) but it seems to have worked out.
