Default Re: Torque Spec thread

I was about to post about the transmission bellhousing bolts, then I realized I had an old print out in my hands.

While I'm here, here's the e-torx socket sizes for the bellhousing:

M12 - E14
M10 - E12
M8 - E10

Reference: My hands

EDIT: Actually, there is still a differerence from post #1 to the PDF for the M10 starter bolts. Post #1 lists 40ftlb, PDF lists 33ftlbs.

Sweet, good work.

How about the torque for the exhaust gas valve (EGR) nuts next to the headers? Reinstalling a new block off plate after over-torquing the old one and bending it.

I can't find any information on this. It is the same nut that holds the fuel filter bracket and idle control valve bracket, which I can't find anything for either.

Since it is an M6 8.8 hardness, I would go with 10 Nm / 7.3 ft-lbs / 88 in-lbs which is the default torque for that size and hardness.

That's what I went to from your chart in the beginning of the PDF. Started at the grade 8.8 torque spec, and seems to have sealed. I also added a bit of high temp RTV since I had problems with this seal last time.

Flow,

The flywheel bolts section has a note for not using loctite. You may want to add that a thread sealant on the bolts is required though. New bolts have it applied already so it is necessary for those reusing.

Those are stretch (torque-to-yield) bolts, you should not be reusing.

Meaning they are single use, when you tighten them down they deform, so you can't effectively reuse them.
