As I said in my introduction post, my motorcycle is dripping oil, which was seemingly caused by the (worn?) oil-pan gasket. So I decided to replace this gasket.

I noticed that someone has already had a similar situation.

Anyway:

- Took the exhaust off.

- Emptied engine oil into a bucket

- Took oil-pan off
Image

picture after cleaning with new (Athena) gasket:

- Installed the oil-pan, tightened it's screws in a star-like pattern.
Image

- Refilled the oil:


Image


DONE.


I didn't start the motorcycle. The engine didn't run. Oil didn't get hot.
But while installing the exhaust I noticed: THE ENGINE IS STILL LEAKING OIL

Right side (brake pedal side):

Left side (clutch pedal side):

I don't know if it is another gasket which needs to be changed. But if the oil would have been leaking from one specific point which is above, the oil wouldn't be around the whole engine pan. And it actually looks like the oil is forming at the oil-pan gasket. Maybe the oil-pan is crooked (doesn't look like it is).

I don't know what to do. Will keep you updated.
(I still haven't started the motorcycle btw)

From what I can see in the photos, I would suspect two leaks. One from the clutch cover gasket and one from the o-ring that fits between the oil-filter plate and the sump. Fortunately, both are easy to replace. Much easier than the sump gasket.

Just staring at it won't fix anything. So I've ordered a clutch gasket just in case. It should arrive saturday.

I will clean the bike tomorrow :oops:
I think it will be easier to locate where the leak is after cleaning.

@Radare

Last time I ordered the oil-pan gasket I had also ordered an oil filter.
But I planned to change the oil filter together with new oil (will probably be in the spring because I'm not allowed to ride before then anyway).

But, did you mean that ring which is at the end of the filter or is it something made out of the same material as the "normal" gaskets?

Image

(This filter also has a bolt-head at the end which looks handy to me)

I will upload a picture of the old oil-filter in an hour. It looks as if they scraped that filter. Maybe that has something to do with the leak.

*Update
This is what the old oil filter looks like:

I believe Radare was referencing the oring behind the plate which the filter screws in to. Similar problem popped up here: http://www.xjrider.com/viewtopic.php?f= ... &start=280. About six posts down you will find some pics and Radare's description of the problem.

You will find the oring as number 3 in the diagram here: https://www.partzilla.com/catalog/yamah ... il-cleaner.

@Seca-Seca!

I will take the O-ring off the new oil-filter and place it on the old one. (Just temporarily, to see if that's the cause).

Not sure if I've got enough time today. Otherwise it'll be tomorrow. Will keep you updated.

*edit
Nevermind. I see that it's not the part I thought it was. I'll see if I can order it.

The oil filter housing is a two-part design. I don't have any photos of it, that I could find, but here's a snippit from the parts manual. Part #3 is the o-ring which fits in between the oil filter plate and the crankcase. It will leak and look like its coming from the oil filter or the front of the engine. It's a separate oring from the one on the filter.

Image

To replace it, remove the oil filter, unscrew the oil filter bolt and then prise it off. You'll want to do all that during an oil change as quite a bit of oil is lost in the process.

I didn't manage to find that O-ring at any parts dealer in the Netherlands. I can order one from Belgium, but that will cost 11 euros, which is too much in my opinion (for just a rubber ring).

When I've got some spare time I will disassemble the oil-filter plate and measure the ring to see if I can find it at a local automotive shop.

I have washed some dirt off the bike today. I've only used a garden hose so it isn't really shining, but at least I did manage to see where the leak is:

Also, the new gasket arrived today. I will be changing it soon. :)
