Stripped sump plug thread
« on: 05 January 2008, 19:01:22 »
My 2.5td (BMW engine) has a stripped sump plug thread. (Last serviced by Vauxhall!) It has an M12 x 1.5 plug. Has anyone replaced this with an oversize, and if so which size.

Thanks

OK Guys, I just drilled it out and tapped it to take an M14 x1.5 plug, only an hour's job with the oil change, and the larger plug will make it less likely to strip in future. Incidentally I used a 12mm drill rather than the recommended 12.5mm, and it was the ideal size in ally, probably 12.5mm would be OK in steel.
On this subject, I rather like the look of the Femco replacement sump plugs, with an integral drain, especially for ally sumps. Has anyone any experience of them?

Cheers

I still stripped mine after retapping. And I used a torque wrench (set to 25Nm).

I will be trying those quick drain ones when I next change oil...

Hmm. They look interesting.

I wonder if one could be fitted to each gearbox sump too?

fitted a femco to last td. (not the low profile one). Took the whole thing out over a country yump. was looking at the idiot lights afterwards & stopped a soon as light came on. motor ok after.
If your current plug is still in , I suggest pila oil pump, suck out thru dipstick, c60 Euro, job done while changing filter, no grovelling needed.

Did wonder the problem with it being low.  Never had any faith in sucking oil out....

May just have to put the undertray back on for protection...

 :o

Maybe not then.

I'm still tempted for the Westfield and MX5 because it's a pain to get under them and the plugs are both on the side of the sump.

I originally bought for my ski boat. Most marine engines use pump out & are expected to last forever. However with 4.5k oil changes it's a godsend. 22.5k this year.

Why is everyone talking about 4.5k oil change? my '99 td (BMW engine) is DEFINITELY 7,500, and I'm told they go much longer in the BMW chassis, with a warning to advise that oil change is due depending on condition. I suspect the shorter interval is for different engines. I like the sound of pumping out with the Pila, how much? £40?
