Changed oil today and found that I did not have a crush washer on the plug. There was an o-ring instead, the plug was grooved for the o-ring, is this common or do I have something different. Used Castrol 20/50 oil, the stealer gave me a couple of crush washers but they were to small for the plug. Anybody have a comment :scratch_one-s_head: (popcorn)
guessing someone swapped plugs, , randy should know if yamaha used them at all (popcorn)
Perhaps you didnt actually remove the correct drain plug. The drain plug is located near the front of the oil pan on the bottom of the engine behind a small aluminum boss thats made into the oil pan. It is aprox 3/4'' in diameter.with a screw in its hex head. IIRC I use a 17mm socket to remove the drain bolt. If there was an O-ring there instead of a crush washer thats most likely not the drain plug you removed.

Actually I did remove the plug right behind the boss at the front of the pan. I had to use a 19 mm socket to do so as per the clymer manual. No leaks and I put about 3 and 3/4 litres of oil in. Filled it to the top of the line in the window. I was wondering if somebody prior to me had to install a new oil plug because of stripping the old one. What do you think, Randy.

Add on. This plug did not have a screw in the center of it

I have 2 FJ's, drain plugs are 2 different sizes, one has a screw in it, one doesn't. Owner oil changes on bikes are common and so are stripped plugs. As long as it keeps the oil in and can be tightened ( reasonably!!!!), is grooved for the 0 ring and hasn't previously leaked, move onto the next job.

i changed my oilplug for a dimple brand, better magnet than oem , and takes a smaller socket, so much easier to drain the oil as i dont have to fight the socket to fit between the exhaust 4/1 (popcorn)

What do you think, Randy.
Here is the factory drain plug; Drain Plug (http://www.rpmracingca.com/proddetail.asp?prod=engine%3ADP)
It is designed to use a steel crush washer; Drain Plug Gasket (http://www.rpmracingca.com/proddetail.asp?prod=Engine%3ADPG)
The is a chamfer on the oil pan that an o-ring can seal into, but that was not the design.

Randy, this plug has a groove machined into it and has a larger shoulder as well. It still takes a 19mm socket to remove it and it has not come loose at all. This is the second oil change this year(first one done by a shop) and it has never leaked.

The next time I changed oil I will take a oicture of the plug and try to figure out how to post to the forum :scratch_one-s_head:
Does it look like this?
