It is in the 964 diy section on this website. Takes a while to do, but not that hard. Good luck.

Valve Adjustment Questions - it sounds easier than it is!
We've read all of the posts about doing the valve adjustment -- have the special feeler gauge; also got the .0025 and .003 gauges to try the backside method.
The adjustment at the elephant's foot appears to be straightforward and I appreciate that you have to have patience, but the Porsche gauge and the physical space that there is to insert it doesn't seem to match. It appears that the only way to get it to fit is to back the screw out, fit it in, then wind the screw in and then hope you can get it out.
In our case we have no reason to believe it is out of adjustment - ie there is no ticking noise - however we don't know when it was last done so we want to check them and only adjust if needed -- having difficulty with the checking!
A consideration is to wind the adjusting screw to close the gap completely and then use the Bennett VAS adjusting screwdriver to set the gap, lock it in place and not use the feeler gauge to double check? Any thoughts?
We would also appreciate any tips/suggestions on use of the feeler gauge.

Wondering if anybody was able to use a regular gaping tool or is imperative to use the specialty one...Where did you buy yours,I guess the regular parts stores doesnt carry them,are they specific for Porsches?
Thanks!
Thanks!

We actually purchased the specialty feeler gauge from Pelican with the .004 blades. However, Pelican tech forums had an article about doing a valve adjustment from the backside and it recommends regular feeler gauges - .0025 and .003 - we purchased these from a local store which is a major tool/nuts and bolt supplier.
We're going to start a new thread with our earlier post and see if we strike up some opinions/advice on the process -- we've done all the prep work but are really having a difficult time with inserting the feeler gauge.

About to do a valve adjustment on the 964 . Everything seems straight forward like the older 911 engines.
ONLY thing is how do i turn the engine over by hand?? to get the 120 deg TDC marks lined up .
The fan 24mm nut /belt doesnt have enough stick to turn the engine over and EVERY tool in my box cannot reach the crank nut. its a tight fit .
any suggestions

Takes a lot of time ..... the first time. Now, I can have it done in a day if that is all I'm doing.
I highly recommend the back side method (yeah, that's what she said ..)

Yeah I know but I have been doing track days and just changed it (change it every 2nd track day). I will not wear the oil out before the next track day. Not sure when the valve adjustment was last done and am worried they are out of spec. I just do not want to waste all that oil if I can avoid it. If not possible to do ot with oil in the tank I will drain that too.
