I am having a problem on a new 2.2l conversion where the circlip on the aux. housing shaft that holds the timing belt gear slips back out of the groove after a few hours of operation. I have replaced the circlip with a spare and the problem reoccurred. Visual examination of the groove as compared to one on a spare shaft does not reveal any issues. The cam and aux. shaft gears are new htd gears from Lotus Bits. Belt appears to ride nicely in the middle of the cam gears and engine runs great. Has anybody experienced this problem? I am thinking of pinning the gear to the shaft to keep it from riding back. Am I treating a symptom or solving a poor design issue? I have done 2 other 2.2 conversions and have never experienced this problem.
