19 ft. lbs. - and no future plug or pan issues.

 

i did have the misfortune of acquiring a bmw with a drain plug that just spun. Had to time sert that one. Definitely don’t want to do that again.

 

^^^^THIS^^^^

Also...Insert the red straw into the Brake Cleaner spray can and make sure the orifice is clean before you insert the hex tool.

 

They have windows between the shop and the waiting area so I have watched what they do. They just put the car on the lift, remove the old filter, pull the drain plug and then walk away to work on another car for 30 minutes. Then come back to put the new filter kit in along with the new drain plug kit, pour in the new oil so yes....probably about 15-20 minutes of actual labor. There was a 997 GT3 there last time I used them and I saw a 997S there the previous time so as I said, the dealership has given them business that's obviously trusted and at a bargain price.

Only negative. They don't accept appointments. First come, first served. Again though, they have enough lifts where I don't think I ever had to wait more than 10 minutes.

 

This is good info, thanks. I have a 991 & 718 and both call for 37-38 ft/lbs which I thought was too much.

 

The factory service manual specifies 50 Nm, which is 37 ft-lb for the 991.1 oil drain plug. I have been using the aluminum "generic" drain plugs from Pelican Parts but will be using the OEM item going forward after today's mishap.

 

You're solving the problem the wrong way. Neither the aluminum magnetic plug nor the OEM steel plug need anywhere near that torque value when being threaded into an aluminum sump. Doing so will make your plug outlast the sump. With either plug torque it to 19 ft lbs. That's the value I use on 9 cars (7 Porsches) for all the flanged drain plugs - sump, differential, trans, etc (pipe thread type plugs without s flange are different).

I used a left extractor today on a piece of gym equipment for a customer. Eastwood tap wrench to go with it. I hate hex sockets personally esp smaller ones. The harder metal always wins and its usually the tool.

Anytime im unclear if a bit is seated ill take a hammer and tap the bit in a few times. Seated is seated. Bondhaus makes a set of allen keys that are cut with a sharper edge for added grip.

all it does it keep the oil in. I just did the motor mounts the other day and thats 63 ft. lbs, i wouldn't go anywhere near half of that for oil and aluminum. 18 woul even work ha ha

 

anybody wonder why Porsche came up with that torque figure? 36 is almost double 19! been using 36 for the past 3 years, with the same oil drain plug, without a problem but would probably go to 25 on the next one to see if it will leak.

 

2009 C2S 2002K miles

19 ft lbs for most of those miles and never a drip. That high porsche spec is a mystery and asking for trouble.

Since a lot swear by 19ftlbs, i shall do the same then... but what is the source of 19ftlbs? Where did this number come from... i know its for the filter cap but.....

 

For me, it was when I purchased the LN magnetic plug... it is what they spec, so I used it.

BTW, buy a bag of washers, you should use a new one at every change. Cheapos on Amazon or at a parts store are fine, no brand issue with these things... it is just O rings stamped from a sheet of aluminum.

I believe it was Petza who suggested these washers as an option ...

Hilitchi 180-Pcs Metric Dowty...
I've used these now on my cars as well as for several friends, and they have been great.

 

This is what I used, perfect fit. I tried a few different ones including those marked as 18mm but this is the only one that fit.

This was after someone over torqued the drain plug somehow on 2 of my cars simultaneously. It was either the shop that did the oil changes last fall, (they denied and claimed 19 ft/lb) or the previous shop the year before (likely). I kept torquing up to 40 lbs and stopped there. Still leaked. I tried the bonded washer from grainger and it has worked wonderfully plus has the added bonus of being about $950.00 cheaper than a new oil pan.
