Can someone tell me the torque for the oil pan bolts on my '84 Euro? I seem to be having trouble finding it in the SM.

Thanks!

7 ft/lbs or 84 in/lbs.

I appreciate it!!

Depending on the gasket/hardware, 25 inch-pounds seems to be the recommendation as long as you are using something to keep the fasteners from loosening -- yamabond or loctite on the threads, or locknuts/spring washers.

In general, the spec for 6mm hardware is 6 newton-meters +1, which is 4.4 foot-pounds or 53 inch-pounds at the low end but no more than 5.1 foot-pounds or 61 inch-pounds. Don't overtighten!

Ahh, I was referring to the torque specs for 32v motors.
M6 diameter bolts = 8+2 Nm or 6 +1 ft/lbs or 72-84 in/lbs.

Is there any actual difference in the bolts or does Porsche just increase the torque value to hold the car together better .

Edit: The torque value only changes for the M6, the rest of the torque values for the different bolt sizes (M8, M10) are the same between the different engines.

I think it's the same hardware -- I looked in the tech specs book and it's actually 6+2 nM. Maybe too many oil pans leaked...

So I should be using 4.4 lbs of torque if I have 6mm hardware? Might I have different size hardware? I know not to overtighten, dont want no leaks Do these cars have studs, that go into the block, that have nuts applied or bolts that thread directly into the block?

Same pan, same bolts.

JKelly

A good compromise between the two suggestions would be 8Nm or 6ft/lbs or 72 in/lbs. They have bolts that thread directly into the block.

You can buy a stud/locknut set as I've done(928motorsports.com), or you can use the original bolts. IMHO the original bolts need something to keep them from backing out, like I said above loctite or Yamabond on the threads. Seems they always loosen up otherwise.

I appreciate all the advice!

Thanks!

As already stated, not much tightening at all - pretty much a bit past 'finger tight' or else you risk bending the pan.

Dave gives good advice on using a thread locking sealant.
