Does This Oil Look Funny?

[ddaniels]

Good thing I pulled the oil pan. Look at all the ground up plastic and metal shavings!

Wow, hopefully it is all from something easily replaced, like a water pump. And I see Yamaha is still using the same oil level sensor from nearly 40 years ago. More pics please when you find the failed part.

The ground up plastic is from the cam chain guides, primarily the one on the back side of the motor that the tensioner pushes against. I installed the tensioner incorrectly making the chain too tight which caused the chain the grind the guide down. The guide is basically metal inside with plastic surrounding it. It did get into the metal which I'm hoping is what the metal shavings are from. I've already replaced both guides. The chain thankfully is still in good shape. I WAS thinking about flushing the engine but I would think that has to be done with the pan on and the engine running, no?

I agree about the level of support at FZ1OA. I may do what you suggest. I haven't taken the pump off yet. I got tired after removing the pan last night. I'm expecting to find it full of debris.

How can you do a flush with the motor open at the bottom? What am I missing? Bike has about 49,000 miles.

I'm just talking about pouring a couple qts of cheap oil into the oil filler hole and watching what comes out before buttoning up.

Oh ok. I was thinking of pouring some into the top cam area since it's still open.

I wouldn't waste oil by just pouring it down the cam chain tunnel. Buy a gallon of Supertech diesel from Walmart and take the bike for a nice ride then come home and dump it. If the oil looks brown do it again.

 

[ddaniels]

Much better.

No I'm on my back. No lift available in my garage.
It's amazing how the grease comes off using Fast Orange hand cleaner to scrub it.

A trick I learned with a GS that the oil screen bolts were stripped was to (carefully) lay the bike over on its side with a tire or something to cushion it. MUCH better access to the bottom.....

If you would see that on a Goldwing -- Head gasket time !

I am not cure of your bikes design - but it is surly water in the oil

A GL1200 I had once was the place I learned this lesson.

Good Luck

Thanks Carl. The water pump and oil pump on the FZ1 are housed in the same unit, only separated by two seals. If these seals leak, coolant gets in the oil. It's a known issue and where I'm looking before pulling a head. Especially since I just got the top end buttoned back up yesterday.

Whacha think?

Not really, I want to know how oil can be funny?:-k

You think I'm funny? In what way.
also why did it settle out with a clear layer on top? More than water going on. Water being denser than petroleum.
