Was continuing my attempt to run down a oil leak and I think I have found the cause but I do not understand what could be causing it. When I replaced my timing belt I had to remove the left side cam reduction cover, the cover behind the timing cog on the left side of the engine, to get the water pump out. When I replaced the cover I installed a new oil seal and gasket.
Now I have oil coming out of the small vent hole in the back of the cover, dont understand where this oil is coming from and what is this vent hole venting? The oil is working its way down the timing belt cover and exits around the clutch cover. I had thought that was my problem so replaced the clutch cover gaskets but when the leak persisted I started working my way back through what I had removed for the belt replacement and found this issue. There is no oil in the area of the timing belt, it is dry and clean, it is just leaking down the back of the cover (outside the engine) until it hits the rubber seals where it then follows them to the bottom of the timing belt cover.
Was wondering if anyone would have any ideas before I start pulling plastic and draining the rad. Am ok with replacing the oil seal in the cover again if it is needed but want to make sure there is not any thing special that needs to be done before doing the replacement and having the same problem. There is a note in the manual about not driving the seal to deeply so it does not block the vent but again I dont know what it is venting and how oil would get in the area being vented.
Any wisdom would be appreciated
