Moody Blues

[Mr Chevorlet]

I should of called my truck Moody Blues instead of Marathon Blue, I had sprung a oil leak on the top back side of the engine, I tighten the Distributer, and the oil sending unit not leaking,Not the valve covers,its only on the passenger side top and running down the back side of transmission passenger side, could it be the rear intake gasket, I ran the engine off and on without the body on it for months and never had any leaks, but low and behold i put the body on and finish the truck and within a month i get a leak. And its not a small leak either. I tried using a small mirror to see on the back but the engine sit really close to the fire wall, I really did not want to pull the top of the engine but it looks like i do not have a choice.
