Hi all,
I've got oil coming out of the road draft tube to the point that at 55 mph, if I go 15 miles, it will run a full quart out on the ground.
Recently freshened a 1955 272 out of a Country Sedan wagon. 46000 original miles. Distributor was frozen and clutch was in need of replacement.
The engine was completely disassembled and sonic cleaned, new rings, bearings, seals, etc. the crank was turned 10/10. The cylinders measured standard bore to 0.0035 oversize without taper so I honed the cylinders and used new cast rings.
Camshaft was reground.
New oil pump, timing chain, and non-loadamatic distributor installed.
The drain tube is completely clear. The new breather filter fits the mounting saddle and is slightly crushed by the lid when tightened down. The oil fill breather is original and free-flowing.
What am I missing?
The engine runs great. No smoke from the exhaust. No miss. I've got 20 minutes of run time with break-in oil and about 20 miles with conventional 10W30 on the car.
I did not do a cranking compression check yet but can and probably should.
Any ideas? Should I install the valley pan with road draft tube, plug the original hole like a T-Bird, and forget about it?
Thanks,
Nick in WI
