OT: Any Jag or car-engine-sages here?

When I started to read the OP I thought: "they must have lubed the back of the bearings." But then I read it happens every two turns of the crankshaft - which exonerates the crankshaft and pistons. When I read the distributor shaft is already in, as well as the oil pump, I had very little doubt about who to "bring down town to have a talk". We'll have to wait for an update from Catfish.

You're right. We need an update. Sans proximity to the motor stand, it's as difficult to diagnose as a problem relayed via telephony.
From the mechanical point of view there will be some resistance expected from the new (unseated) piston rings. With the reported resistance every second turn I suspect a little binding on a piston stroke on either the power stroke or the exhaust stroke. It could also be a bent distributor shaft or a bad tooth on the gears.
I've had my mechanics question my diagnostic skills. Usually to their detriment.
OK, so you pulled the left front wheel when I told you the problem is in the right front? You're old enough not to be daft! I told him.
I learned the hard way when my father assisted me with a new radio install on my first car. The radio worked fine...when the turn signals had power applied. After that debacle, I did everything myself when pop wasn't around.
