Question Oil Drain Redux Napa Piggyback 5/8 for M16

I have a stripped oil drain/plug on a newly acquired 06 R12RT. Through much research here and elsewhere, I am ready to use a Piggyback replacement(versus Timesert,Helicoil,re-tapping etc.) Lots available to choose from, but none in the M16x1.5 size of the original BMW bolt. NAPA has a 5/8-18 Piggyback plug available. Keeping in mind that the main bolt will never be removed once in place,with only the smaller centered Piggy Back bolt to be utilized for draining, could the 5/8-18 be used??

Well my answer would be- "maybe, it depends...."

5/8" is 15.87 mm, so a lot depends on how badly the hole is stripped out. If they make a 5/8 "oversize" piggyback it would make the decision a lot easier. Anyway, if you can get the replacement plug to hold even with a couple of threads then I'd say go ahead and use it, using a generous amount of JB Weld or similar hard set epoxy. You can also take a piece of stranded electrical wire and put some strands in the hole first to tighten up the fit a minute amount.

If you can borrow a 18mm spark plug tap, you could also tap it to 18mm as that is also a standard size.

Anyway, I'd probably try epoxying in your 5/8 plug first, and if that does not hold for whatever reason you can tap it to 18mm later.

Thanks Greasemonkey

That was the best kind of advice...logical,hopeful and cautiously care free....I haven't actually taken the plug/bolt all the way out...I was doing a service(had already let the filter drain) and felt how gacked up it was,as well as observing bright silver thread slugs, so I just put it back tight....Finished the service(valves and TB) and put a quart to top it off.Also changed the filter,which was about 7k total....So, I am going to see how it goes with the 5/8 and proceed,(unless of course a fuller mind than mine makes a strong case against it,of course). Will look further into tapping an 18,especially if I can piggyback it....Thanks again...

Another option is Fumoto http://www.oildrainvalve.net/ which is available in 16 - 1.5mm. It is a one time install and could be held in with JB Weld if your bike isn't stripped to bad.

Another thought is to just drill and tap your existing drain plug and epoxy it back in.

Trying to avoid that...

Considering using the Fumoto, either by original size or tapping out to 18mm....but will probably give the 5/8 Piggyback a try first. I really don't want to have any repaired aspect to be part of the future drain procedure. Methinks...
