Boxster 986 timing tensioner bank 1-3
Happy New year to you all...
Scotsman here with a sick 1999 2.5 boxster... It has an oil leak that is coming from the timing chain tensioner on bank 1-3. I believe it is the washer that has corroded.. I have read various posts regarding reseting timing etc but cant seem to find anything that specifically deals with this issue... I have been told that as my engine is the early non vario cam type that I merely need to get the engine to TDC and lock it there. No need for the cams to be locked... Firstly, can anyone confirm this? and secondly, when told to put engine at TDC does this need to be compression on bank 1-3 or do I simply turn crankshaft pulley until mark lines up and lock? hoping some kind soul can start my new year of with a solution... regards James Glasgow, Scotland |

You can then remove the leaking tensioner and replace the crush washer. |
Oooh, red alert. There are TWO "TDC" positions neither of which results in all 24 valves resting closed. That's why we set one bank, rotate the crank 360 and then set the other bank.
Follow the procedure for valve timimg, verify the cam notch for bank 1 and THEN proceed as above |

JFP,
You're absolutely right, I just see this detail left out of the description often. I'm sure you know these engines way better than I ever will. |
