MB Doc,

When I pull the cam covers off, will it be obvious as to which tube is defective? Ive read that the end's pop off on them, thus loosing pressure. The tick seems to be coming from the passenger side, although my mechanic swears its on the drivers side. Perhaps there are more than one bad. The tubes are around $15/each, so replacing all 32 of them is going to be expensive. Would you agree to just replace the ones that are bad? If I dont find a bad oil tube, is it possible it could be a bad cam follower? I had a cam follower go bad in my diesel.

thanks for your help.

Andy
