I've had new replacement of the seals ,timing belt ,water pump,tensioner and PCV breather box etal . Leak has increased from drip to gush on front cam seal. No other leaks. Mechanic replaced front twice, one oem once with dealer supplied. Engine runs smooth , I'm wondering if a speedi sleeve might save the day . ANY ONE ever try them and do you possibly know shaft diameter? I am going to work with different mechanic ,think perhaps the first scored the shaft. He wanted to put a different engine in. Felt that might be less work.
