Fresh rebuild, oil everywhere

I had a problem like that and it turned out to be the wrong size oil ring expander and rail set. They felt really loose when I put the motor together, and said to myself, if it seals up it will fly. Well, it was just as you described, pulled the motor down and replaced with a bigger expander and rail set and the car flew. If you are using Total Seal look at the label on the oil ring package and see what size is printed on it. They had sent a4.040 expander package while the top and second rings were for a finished bore size of 4.100. Believe I wound up with a 4.060 oil package set .

I always use a digital fish scale and pull a piston (with the oil ring package installed) through the cylinders to check for how much drag. I shoot for around 8 to 10 lbs. Its a little tricky, put try and keep it moving smoothly in the cylinder.

Good Luck

We learn a whole lot more from our mistakes than we do from our successes.

Hey, how long is your camper footprint? Look like it fits perfect without overhang.
