I’m in the process of rebuilding this motor. The head was resurfaced and rebuilt with new guide seals.

everything feels pretty smooth, but there is clicking or pop about every 180 degree turn that comes from the valves.

sounds like a valve snapping closed or maybe something in the Vanos sprocket?

anyone know of this is normal?

 

not having oil in the system may effect these moving parts

 

Yep. that was my suspicion as well. I went ahead and filled the VANOS sprocket with some Lucas oil and the noise considerably dropped.

Thank you for your reply!

Same thing is happening to me. Sounds like a suction pop every 180 degrees. Fid you have any issues with this after the build?

 

You can pre-lube the engine, all you need is a Motive pressure filler and an oil pressure test kit. Use the adapters in the kit to connect to the motive filler to the engine. Connect the filler to your oil filter manifold, pressurize the filler, and let the oil flow.
