, sorry , couldnt resist, just joking)
I thinking that maybe you didnt notice that 88cobra is from canada and switched to synthetic at 145,000 kilometers, which is around 87K, or 87,000 miles, not an unreasonable mileage to swith to synthetics on a 5.0 in my opinion. I switched mine around this mileage and have no leaks that werent there before.
88cobra - its not the oils fault your seals and or motor were neglected and they need replaced, and you dont have to pull the motor to change any of the seals you mentioned. Front and rear mains are easy, as well as the rocker covers. You might have to riase the motor to change the oil pan gasket, but shouldnt have to remove it. Those cold a$$ canadien winters arent easy on gaskets.
