Default Timing cover torque

Ive been searching for 45 minutes, some great information but I haven't found the torque specs for the timing cover bolts. I want to try replacing the little soft washers to see if that will clean up my leaks in the area before I go any further. Anybody have these handy?

TIA

Hi Andrew,

You mean the "valve covers"? If so.....

I torque them to 3 foot pounds - then go back re-torque to 6 foot pounds. Why 6 foot pounds? Using the method described on Robin's EXCELLENT site (http://p-car.com/) - 6 foot pounds is just about what I get. I use the torque wrench to try to get them all the same. However - I don't think it's critical to use a torque wrench for them - I'm just "that way"..

If you mean the timing chain covers - I have that somewhere, but they should only be about 6 foot pounds, as I recall?? I'll try to find the exact specs for them....

Hope this helps!

John

I replaced the two lowest cup washers in the LR timing chain cover - which nicely stopped the slight oil leak: I just tightened them until the steel insert ( around the stud) made firm contact on both ends.

Garth is right on - most folks do it by "feel".. However - I did find it - and it's 6' lbs. I didn't find it in either the 964 or 993 Workshop Manuals - but rather the 911 Carrera Workshop Manual. It's the only reference I could find to ANY torque values on these - including my original 911 manual (Vol 1) and later years. Since these are paper based (originals) - I can't search a PDF file for them - I have to use my eyes to do my "searching", which aren't great - but, they still work (sort of )..

HTH!

Hmmm, I thought it was 7 (as tought by Gerry Woods). One foot pound is nothing anyways!

The problem with these low torques is that you have to have a very good low torque wrench (I have one for 1-35 and another from 20-200, both calibrated often). You should also excercise the wrench first (i.e. use it on a nut that is tighter so the wrench detects the torque a few times).

When I took Gerry Wood's engine rebuilding class (excellent by the way!) the told us, that in the case where you can't get a torque wrench in, use your pinky to hold the wrench. He figures your pinky is more sensitive and able to judge the tightness.

I often just go by feel, I have done enough of them and some using the torque wrench so my "torqu-o-meter" in my arm seems to work pretty good. No leaks yet on all the cars that I have done (knock on wood).

Cheers,

Mike

Mike,

Do you mean "white", "red" and "blue" torque measured by the color of the mechanic's face??

Re the valve covers... lightly does it!
