oil pressure relief valve
dont want to scare anyone but today i removed my sump/oilpan it seemed stuck, but once it freed up i found the culprit, the c clip was sitting in the sump and the spring and end cap of the relief valve were wedged against the side of the sump this gap is around 5-8mm dont know how long its been like it but there was a shiny rub mark on the pan. i never had any oil pressure alarms ever sound and guess there was still enough pressure to hold the valve shut keeping good pressures as logged on the motec when it was fitted. upon discussing this with others it seems this isnt the first case of this happening.

Yikes... good find. So it wasnt the fuel after all?

it was detonation buddy this has nothing to do with my fuel issues. as stated oil pressures were never compromised, and no signs of any damage caused from this as i said its not a once off and others have found the same on disassembling 250/260's just something to be awhere of

well it wont happen again i fitted a washer behind the c-clip and tack welded it to the body of the valve , surprised others havent commented on there findings, a few have contacted me with the same issue causing spun bearings!!

tip of the day,
Flat C-clips are directional. This is because they are punched or stamped out like a cookie cutter. During the manufacturing process one side has a curved edge while the other is square and sharp. The sharp side is the one you want loaded to the groove with the spring so it stays put in the groove better.

yes you are correct but i can assure you not all clips are one sided, and when you buy a valve you should not have to disassemble it to see if the clip was placed right way round. good tip all the same for other applications.

Hey, I'm just saying as I have had upside down Kawasaki clips pop out in the past. People are only human otherwise we'd not need a warranty period!
