Major Oil Leak on Nytro

[flyboy727-200]

We were riding today in Idaho and one of the XTX's suddenly and rapidly dumped oil everywhere. Got it shut down almost immediatly as the yellow check gauges warning lamp illuminated. No damage to the underside of the belly as near as I can see. Towed it out 22 miles to a Yamaha dealership. They will look into it tomorrow. It has not had recent service work done (loose oil filter or drain plug not likely). It sprayed oil on the exhaust and it was smoking like mad as the oil burned off. Any ideas on what it may be??? Just happy I bought the extended service plan.

Maybe u lost the cap on the valve cover

It lost most of the oil in 30 seconds. Seems awful fast for a cap. Just keeping my fingers crossed it's an easy fix as we just got to Idaho and now I will have to rent.

Hears to hoping its something simple for you!

Renting sucks!

Double oil filter gasket is a real possibility. It can take a bit of riding before it blows out causing major oil loss. Exact same thing happened to me. Exact symptoms you describe. I'm sure they will check that first - at least they should. You'll be back on the trail in 30 minutes if that's the case. My fingers are crossed for you!

Loose oil filter? My 08 nytro was the only thing I have ever owned or changed the oil in that leaked with a hand tightened filter. It seemed to vibrate loose after about 500 miles. Had to buy the filter wrench/socket to really tighten it down.

You were spot on with your guess. I am amazed it went over 500 miles with no leak. I admit it was my fault for the double gasket, but who was the engineer who designed the filter that would make that a real possibility???

Glad it was something easy and simple! Back on the trail in 30! Get in the habit of actually pulling the o ring out of the old filter before you spin the new one on. My dealer double gasketed mine at the 300 mile oil change and I gotta say I was in disbelief they wouldn't check and double check for the old o ring on the old filter - should be a shop policy. Anyway - have a good ride!

It's a common problem that most mechanics are aware of and are careful not to make the mistake of doubling up filter seals. This problem is not limited to just Yamaha filters. Automotive and diesel filters have the same issues. I just changed the oil on an Intrepid tonight and the old filter seal stuck to the engine. In some applications it's difficult to change filters and actually see the sealing surface but once the filter is removed it's easy enough to check to seal if the seal came off with it.

In my high school auto shop class, they taught us to use a clean rag and wipe the surface where the gaskets seats. Then you can feel if the old gasket is stuck on there. Plus they drilled it into our heads to look at the old filter and make sure the gasket is on it.

X2. I always clean the flange on the block before spinning a new filter on.

X3 and don't forget a light coat of oil on the new seal!!

Just a word of caution, when these motors blow oil like this you end up with low oil pressure which in turn can very easily damage rod bearings. Just happened to a friends sled. Motor only lasted about 200 miles then self destructed. Do a search on my posts and you will see one explaining what happened and what to do to check for the damage,
