I've gone through my Alfa manual ad I couldn't find the torque setting for the manual gearbox oil drain or the engine oil drain plugs, would someone know what they are?

I have a S4.

Thanks in advance,
Bob

Took a look in the Engine Overhaul Manual

And the Engine drain plug Torque is 30 to 40 ft. lb.
Or 40.6 to 54 Nm
or 4.1 to 5.5 Kgm (NOTE Corrected this had it as 55 and so does the book ???)

Gear box ? Is it a pipe thread ? Nice and tight will do .

You got a new washer ? Right ?

For the record, page 86 of the S4 manual lists it as 7-8 kgm (51-58 lb-ft). Which always seemed kind of high to me but it hasn't stripped yet.

The engine overhaul Manual goes up to 1991 .

They must have had some plugs back out .

It is a big plug so it will take a lot of touques .

But that said it would be a sad day when you stripped the oil pan :mad::mad::(

Sorry, wasn't being clear: this is in the owner's manual, not the service manual. The number seems to appear in a few places at different values.

Thanks for answering my questions.

And yes, I got new washers, I learned a long time ago to never reuse a copper washer. I'm assuming since copper is soft, it squishes a bit.

Just for info, the new oil pan washers came from IAP, I couldn't find the gear box ones on their site but found 22mm copper washers at Canadian Tire that fit very nicely.

Thanks,
Bob

I find they get a lot of marks from the plug . Can be fixed by sanding them flat again . Then Anneal .
Nice when you can find them for 99 cents at the auto parts.

Good link .

S 4 oil drain plug torque

While this is responding to an earlier posting, I just looked at my 1991 Owner's Manual, and the torque listing of 7-8 kgm (51-58 lb-ft) can be found on page 70, but it may be on other pages, also.
