Oil leak?

Had an oil change 4 weeks ago at an aamco shop I've never used.
The defender has always leaked a bit (6 months/less than half a quart).
I went out of town for work for two weeks then family vaca for a week so it's now been sitting in my garage and I noticed a pool of oil under the drain pan. I checked the drain pan plug with my hand and it seemed tight but it looks like its coming from the plug.

Suggestions?
Thanks

They often seem to leak a bit from the drain plug--I tighten mine pretty tight. I doubt they replaced the copper washer, but check to make sure it is at least there and put a wrench on the plug and make sure it is pretty tight. No way to really do much more unless you want to drain the oil.

As suggested by Davis (you gotta love that name), the sealing washer is most likely split or scarred from over tightening and letting oil pass... Since it has little use you could drain the oil into a smallish trash can with a trash bag inside, renew the washer, and refill the engine with the same oil (and probably a little more to replenish what is on the floor and left in the trash bag).

Hope this helps.

gonna do an oil change on my '86 90 today. Little worried about needing to replace the copper sealing washer...
What size is the washer and can you get it in auto parts stores like O'rielys?
Thanks

I change the copper washer (genuine) every 3 oil changes, also have the magnetic drain plug nut.

No leaks.

Maybe the shop forgot the washer? (or dropped it)

More likely someone that is paid hourly and doesn't care about the quality of work. Flat-rate mechanics might take short cuts, but they must attain a certain level of quality, otherwise it would hurt them in the long run. A mechanic doesn't get paid to fix his mistakes typically.

Can't tell you the size....but take the drain plug to NAPA. They should have a large selection. I get mine from my local JD dealer.
