Build thread- 73 duster, forged 5.7 w/ PS and AC, 5 spd, big brakes and floater rear
Well,
I think I might have found my rear main seal leak problem. It seems I had 2 psi in the crankcase! I had forgotten to cut holes for my breather tubes when I first made the gaskets, so I poked holes in them with my dipstick tube after installed. I have now added a breather to one and hooked up a pan e-vac to the other. After pulling one intake and cutting a proper gasket hole, the gauge showed 0psi. Still need a catch can /air-oil separator for the pan e-vac side.
Also, I checked out the clutch once everything was cool. Pretty much the same. So it's definitely an air thing and not a heat thing (y'all agree?). Nothing else was done last night.
I also trimmed the bell housing while under the car. After re-doing the exhaust,
This was the low point by about an inch, so that's what I cut off. It was dragging on my garage lip (just barely). Prior to redoing the exhaust, I couldn't even get back in the garage (backing in). I should have 4-4.5" at all points now, and 5"+ at the oil pan.
