Yes. Sounds like your engine builder has done a poor job. I would bounce it straight back at them without touching it. 05 L322 4.2SC

If unmetered air is getting into the engine then it could all sorts of strange goings on I guess.

So I sent the car back to the rebuilders and they then gave me the car back still with air leaks, misfires and shorter clearances between the tappet and the cam shaft lobes.

I had to take the rebuilders to court and got most of my money back.

So 25,000 miles later after shim/bucket engine rebuild on LPG on my Range Rover 4.2L L322 2007 Supercharged we have measured Valve Seat Recession. I have also completed a compression test to check pistons.
