Hi all, 2000 Boxster 2.7L Tiptronic, 117k miles. Geared up for an oil change and chain tensioner(s) replacement in the coming week. I would like to adjust timing while I'm in there (I have cam deviation readings at cold startup and after 30min drive, and have confirmed proper function of the variocam solenoids). I have not gotten under/in the car yet to determine if there is enough space to do this with the engine in the car as I am in the part-ordering stage. Just wanted to get your input on this so I can get all my ducks in row with respect to all parts I need to perform the work. Timing adjustment appears to be straightforward in itself. I just don't know if I will be able to see/access the camshaft sprocket bolts once the pump is removed from each bank. If access is achievable then I will go ahead and order the scavenge pump o-rings and new encapsulated bolts to perform the work. If this is an engine-out service, then, well, I'll just stick to the tensioners for now. Any input and guidance is greatly appreciated. On a side note, I have modeled and 3D printed a cam locking tool for the M96.22. It looked like everything out there for purchase was for the M96.23 and later models. I will let you know how it performs after I do the work, but if anyone is interested in the solid model or stl file just let me know. I have printed out a few extras just in case. Thanks for your help! -
I've got the three chain tensioners sitting on the shelf waiting to change with the oil in few weeks. From the bottom, the IMS (I think) tensioner is the easiest one - totally exposed for a socket. The other one accessible from the bottom is "fenced" by a couple of metal coolant tubes. Can the coolant tubes be temporarily moved out of the way by undoing their straps to gain sufficient access to the tensioner? Or, do the tubes have to come out by decoupling them from their in and out rubber hoses? (I'm trying to avoid cracking open the coolant system...) Does the cam have to be locked in TDC with a pin through the pulley hole? Is there still a chance that any of the three chains could jump a tooth while removing the existing tensioner or putting in the new one? I plan to complete each tensioner completely before moving to the next one (two tensioners will never be out at the same time). Any other tips or tricks? Thanks for any advice. -
I bought 3 new chain tensioners for my 1999 Cabriolet. The two that are accessible from beneath the car I replaced. I did not replace the upper one because it is under the AC compressor. I understand the AC compressor needs to be moved to access the tensioner and this is accomplished by removing the 3 compressor bolts. But Bentley says you need to remove the power steering pump reservoir too, which looks messy. I suspect you need to remove the reservoir if you are removing the compressor, which I am not. I just need to shift it over. Can anyone speak from been there done that?
