My apologies for being rude, but im in the process of rebuilding the engine in my 2001 BMW 740IL. It has the 4.4 V8 VVT. The block recently overheated and I took the engine apart and needs a block replacement. I just rebuilt the heads and intend on using the VVT heads. I just purchased a used engine from another 740 IL but it has NO VVT. Could I swap this non VVT block and use the rebuilt VVT heads? Reason I ask is because I see valve relief cuts on the pistons in the original VVT block, but on the non VVT block its just a solid piston. Any thoughts, suggestions would be appreciated. thanks

Original VVT engine code is M62TU 1998-2001 BMW
used Non VVT engine code is M62 1996-1998 BMW

No, you can't.

Can you be more specific? Would the valves hit the piston? Anything else?

Well, as you explained in your original post, the M62 TUB44 has VANOS and the M62 B44 does not.

Here's the problem, the 1450 psi of hydraulic pressure used to actuate VANOS is produced by two dedicated oil pumps; one for each cylinder head. Valve timing is varied over a range of 60 degrees in terms of crankshaft rotation with a wider adjustment range than that of a non-VANOS engine.

But, to answer your question, the valves and pistons would line up the same (I believe).

thank you for your reply...is it possible to swap the oil pump from the m62tu to the m62 block to achieve the 1450 oil pressure? Will it bolt on?

Maybe ...

If you try it, be sure to take pictures.

Good luck.
