Wiseco pistons
If you are thinking of using a wiseco piston.........
I have just stripped a rather rattly XR6 engine.
The rattle was due to the gudgeon pin having slipped out sideways past the circlips and out of one side of the piston.
The circlips are the correct type - the problem seems to be due to the clip grooves in the piston being machined too deep.
Spoke to Wiseco Tech Dept and astonishingly they seem to be aware of this type of problem.
I am promised a phone call tomorrow.
Check your wiseco circlips - this engine now needs a piston, liner and crank.
