Major oil leak
Posted: Mon Jul 20, 2020 12:51 pm
Hi Guys, hope you can help with this. Got pulled off track the weekend as it looked like my right boot sprang a pretty major oil leak ..
Dropped the belly pan and cleaned up the oil, from the front of the engine all the way to the exhaust, all down the right hand side. Pretty major leak. After cleaning i started the bike up to look for the leak and not a drop came out !!!!
I did a full top end rebuild over the winter, all new major gaskets , all genuine. Used the bike on track for 2 days . Not a problem . Then this weekend a gusher. I'm fairly up to date with the zxr and this forum has been a huge help over the years. I do EVERYTHING myself.
So, in my opinion its not the pulse cover or clutch cover gaskets, both were new and there's just too much oil leaking for it to be that.
The spark plug tunnel o rings top and bottom were not changed (shame on me) ,possibility but its more down the right hand side than the front.
The only other possibility is the oil feeder pipe from the sump to the head, removed this from the head section only and was able to turn the metal end in a circle without the pipe turning. I have a spare engine so checked its oil pipe and it doesn't turn so it appears the crimp has broken . While this is most likely the cause I'd just like to hear from Cargo, Master, redex etc to see if they've experienced this before.
As I've said leak only happens when it's under load so can't see for sure but everything points to the oil pipe ( which of course is not available new) .
Let me know your thoughts lads
Thanks in advance
