It is time to change the valve cover gasket but I cannot for the life of me, find these torque values on my CD. As a matter of fact, it seems like the Valve Cover is never really reffered to on it's own merrit anywhere on the CD.
I remember someone mentioning 8nm/10nm. Does that seem right ?
TIA

I believe it is 8.5nm

thank you much. Yours must be the fastest reply I ever got on the board...
Not a minute even since I posted the question !

Most 10 mm hex head bolts have a 6 mm nominal shank diamter. Proper torque would be about 60 in-lb.

Duke,

Would 60 in-lbs. translate into 5 ft-lbs 60/12=5 ??

Thanks.

Yes, but 5 lb-ft is tough to gage with a conventional lb-ft torque wrench, either beam or click type, that reads to 150 lb-ft. They aren't accurate enough at the low end of the scale to be reliable below about 15 lb-ft.

For small torque specs one should have about a 300 lb-in torque wrench. I have an old beam type with this scale.

For setting up axle and steering gear bearing preloads, a 25 lb-in torque wrench is necessary.

looking at a conversion table I learned that 60 Inch Pounds converts to
6.77nm. That is different than the 8.5nm that was recommended by danwatt. Are these numbers too close to call?
Still curious as to whether anyone has seen this info on the CD ?

I looked it up in the M103 engine manual - 8.5 NM, which is 73.44 lb-in is correct. It should be on the CD under cylinder head removal. Torque specs are listed at the beginning of the job section.

I thought it was 8nm, I usually set ther torque wrench to 10nm. Be sure to go through the bolts several times. As the rubber seal (gasket) "settles in", it seems like you can go through the bolts several times and the bolt will turn a little every time for about 3 trys, after that the torque will hold steady. Never a come-back by doing it this way.

thank you all. I think I know were I am headed now.
Thanks Duke for the CD info. I just hate it when I go searching everywhere but the correct place....
