Hello, I was wondering if anyone has had any success fitting a Buick 215 front cover to a rover 4l, it seems to be able to bolt on fine but I do not understand how the oil pump connects to the rest of the engine, thanks

You will need a different oil pickup tube, oil pan and a different cam shaft to drive the 215 oil pump.

Thanks for the Reply! Do you have any idea of where I could get these? And shouldn’t the cam be fine so long as I add a distributer drive gear and a distributer? Thanks

Drew it is all different 3.5, 3.9, 4.2 is old school, camshaft drives the oil pump, 4.0 & 4.6 the crank drives the oil pump. You have to change the cam, a must & you have to use every thing on the front of the early engine & you will need a spacer to go in the harmonic balancer for the nose of the crank is different

Ok, thanks, I’m looking at a cam from a 3.5 that is carb and efi compatible, from what I’m hearing, that should work right? And should I get some lifters too? Again, I’m very sorry for being so inquisitive, if you couldn’t tell, this is my first time

Is it definitely a 4litre? Land Rover re-named the later 3.9 as 4 just to differentiate it, the capacity was unchanged but several other things changed.
Some have managed to accommodate the crank driven (and better) oil pump, which was fitted to the "interim 3.9" and later 4.

Yes, new lifters & new cam.

Why a 3.5 cam. Even a 3.5 will run stronger with a 3.9 cam. Find a decent performace cam,

Are you putting this engine In an MGB? If so, why use a truck cam. Get a sports car cam. winking smiley

I don’t know, I wasn’t aware that anything other than a rover disco can would work, can any cam work with any engine? And if so, does it have to be specifically dizzy drive?

They called the new 3.9, a 4.0 (1998-2002) because internally it is not the same. It has different crank, rods, pistons, etc.
