Oil Leak
Need a little help. I have a an oil leak between #1 cyl and the timing chain housing. It only leaks at high rpm. Above 5K. Checked the oil line on top all dry. Would the camshaft gasket or the O ring behind the gear do this? Can these be changed without engine drop. If I mark everything, chain, gear, cam would I have to retime the camshafts?

There is a paper gasket between the camshaft housing and the chain timing housing. There is also a rubber o-ring for the camshaft cover. If these leak, it will be lateral to the head for #1. There is nothing between the head and chain housing but air.
You can't replace these easily with the engine I don't think. I did it with the engine out. Possibly could do it with a partial engine drop. You would need to remove the chain cover, tensioner, idler arm then the difficult to remove camshaft nut and finally the sprocket. Before you do this, though, I would have a mechanic look at it to tell you if he thinks this is the problem.

Changed Cam gasket and O ring behind sprocket assembly, No engine drop, piece of cake. No more leak yeaaa!! But that Fabspeed cat bypass install is another story. believe everbody when they say it doesn't line up correctly!
