Oil leak from bash plate mounting point

[Fisherfury]

Hi all,

Having owned a few 1150 GS's I recently decided to buy my first 1200.

I found a pretty yellow one with lots of extras including Ohlins front and rear being sold by a used bike dealer with really good feedback.

The bike has been parked in the garage since before Christmas and I went to it yesterday to find some oil on the floor. it had come off the bash plate. I removed the bash plate and found the front right side rubber mounting not connected to the sump and that this was wear the oil was leaking from (the bike was cleaned before it was put away). I found that the mounting hole in the sump had been subject to some heat (burn marks around it), perhaps in an attempt to remove a stuck mounting and then it had been filled with liquid metal.

This is very worrying. Does this threaded hole go into the sump (ie not blind) so if there was no mounting screwed in, it would leak oil out (would seem silly to me if it did), or do I have a worse problem (crack in the sump I cant see yet). I was hoping to post some pics but can't see how to do that.

Thanks for any help.

Well hi Fisher..
I reckon should be same as 1150 and that’s just a thread with no connection to the oil sump at all.
Use some break cleaner and degrease thoroughly and let the engine run till warm and see if you can identify the leak
Might be an idea to check the length of the existing screws......
Best of luck...

Sounds like someone may have had the bolt snap and tried to drill it out and drilled to far to me. Can't see another reason why it would be filled with liquid metal.
I think I'd get it welded up just so seal it and not bother with the bolt to the sump plate if it were me. My sump plate hasn't been bolted on there for years because the bolt had snapped there. I just left it as is.

I think you maybe right, I will have dig out / grind off the liquid metal have a good look and then find someone who can weld it in situ.
Cheers

I think you will struggle to weld it in situ, after you have drained the oil as soon as you apply heat it will leach the oil (that will still be present) out of the crack.
A friend hit his gate stop and put a very small crack in the crankcase of a VZ1600. He did not want to remove the engine and strip it.
After much pleading he convinced me to weld it. After a lot of time Tig welding grinding and re-welding finally got it to hold oil. ( never again).
When the job is on the bench it is a doddle.
Without seeing a photo it is difficult to advise, but would it be possible to drill and tap it oversize and fit a bung with the right sized thread in the middle.
