'68 318 to carbed Magnum 5.2: Check my checklist



^
Photo isn't important given the findings, but the freeze-frame of Cylinder #1 shooting oil through it's bore is pretty neat.

That said, some interesting things discovered today:

#1: Pulled cylinder #1's lifters and cranked the engine. Tons of oil coming through bore. Ditto for the rest of the bores on the driver's side.

Conclusion: No oil restrictions here. Lifter problem.

#2: Swapped cylinder #2's lifters over to cylinder #1, and #1 to #2. The lifters from cylinder #2 shot oil without issue in cylinder #1's position, and #1's lifters now didn't pump up in #2's spot.

Conclusion: New lifters not pumping up.

#3: Pulled out a random set of the old driver's side lifters (making sure not to pick the jammed one), stuffed them in the Cylinder #2 bores, with the oil holes clocked forward (remember, these are the lifters with the holes pointing at a 90-degree angle to the dogbone). I put pressure on them with my fingers to prevent them from popping past the oiling hole. After a few cranks, they started squirting oil.

Conclusion: At least one set of old lifters are pumping up.

So...

I don't know what caused the left side lifters not to pump up after I fiddled with the rockers on that side a few days ago. Perhaps the pushrods are pumping air back into them.

With that in mind, I tried this:

#4: I reinstalled all the passenger's side lifters, pushrods, and bores back onto the engine so that they'd oil properly (as they did), and the new lifters on the driver's side. Then I cranked the engine and kept the driver's side lifters pushed down (with my fingers) at the cylinder #1 position.

Nothing.

I'm going to pull the driver's side lifters out and let them soak throughout the day. Perhaps it's trapped air.
