Hay guys just need some info just did a full service on my zxr and whent for a good long ride got home checked the oil filter for leaks and found found oil coming out of the no1 exhaust port on the header anyone know what it means
There are 2 sources of oil for that symptom that I can think of. 1/ rings 2/ valve guide If the spark plug is also black and wet then you can probably assume it is rings. I would think it unusual to see that much oil as a result of a valve guide seal being worn. Can you do a leakdown test? cheers Blair
yeah blair is onto it - if the valve seats are gone, it could be like mine where sludged oil deposits can be sighted down the intake runners sitting right on top of the intake valves, will probably be that same story for the exhaust valves. and yeah, rings/scrapers moving that fast up and down wont live forever - when u drop the oil, next, let me know if there is fuel contamination evident (for my own curiosity) don't stress to hard about it, just keep an eye on the oil lens. start sourcing seats, rings, new valves if it gets really bad she's got at least 30,000km's left!
Sounds like your right about the rings I started and sounded like it was running on three cylinders whent for a ride had no power pulled over started it again and it was fine all power was back sounded normal ill see what its like do have two spare motors time to test them out
if you do find one of those motors to be sound, take the opportunity to strip the old one and do a light rebuild would make a cool thread!
Will do Cal just need to find the time know found full topend refresh kit $300 so ill let u know how it goes
Just make sure it's not actually the valve cover leaking onto the ports before doing anything major, as this was the issue with mine a while back
