Re: oil leak

Just to be on the safe side, check or change your pcv valve. If the valve is blocked, the pressure within the crankcase will cause oil to blow by rear main seal.

If the main seal is leaking and it is not covered under a warranty, try a can of Bearin' Seal or one of the oil leak stoppers, or even the motor oils for higher mileage vehicles. These compounds will soften the seal materials slightly and may help the seal to do its job. Under no circumstances should you attempt any engine flush, it will only make your problems worse.

If you are running a synthetic oil, some owners ave found that switching to dino oil sometimes helps stop the leaking. The oil tends to soften the seal material a little.
