Sump but torque value

[Bill Mac]

I am changing the oil on my '69 and changing the seeping sump plate, so I don't want to over torque it like it has been done in the past. I have looked in my books but I cannot find the value. Help!

Bill,

To answer your question, I looked at several 912 references but found no torque value. 3 ft-lbs is generally accepted as the 'clean and dry' torque, but I will offer this: I use a 3/8" palm ratchet with two fingers and a thumb on the ratchet head to 'snug' the nuts that hold the sump plate on. I also use nylock nuts so the reduced torque does not result in the nuts backing off:


Too much torque will cause the AL screen flange to deform and will pull the sump plate into raised areas around each hole (note filing areas around sump holes to flatten sealing surface):


I have since started using the Precision Matters sump plates:

Peter,
Thank you for the information, it was perfect. I am also installing a Precision Matters sump plate. This appears to be the solution to the warped original sump plates and it looks great.
Thanks again.

there is snug, tight and overtightend, snug to tight, sure it is a matter of feel, wonder if my oil change guys use a torque wrench.

I'm new here and am looking for the size of the torx plug for a Corsa 1.3TD Design. I cant find this information in the Haynes manual..
