3.9 Rebuild - some questions

[alanius]

Hope this it the right place to put my questions.

Here we go:

I've a 3.9 V8 engine block that is completly rebuild with top hat liners, block is as new. It was original a serpentine model from a discovery, but with the oil pump driven by the dizzy.

Now I'm going to use megasquirt on this engine so I didn't need the dizzy anymore so I've putted the front cover from a 4.6V8 on the engine (smaller, no place anymore for the dizzy). Oil pump is driven by the crankshaft.

But I've just saw that I have 2 places where I can put the oil 'intake' pipe (don't know the correct name):

- 1 on the engine block (originel 3.9)

- 1 on the front cover (from the 4.6)

I guess I need to use the one from the 4.6 (front cover) but what I need to do with the original intake from the 3.9. Let it open or block it or... ?

who can help me???

many thanks

regards

Alain

Just done this myself, the 4.6 front cover blocks the "old" (3.5/3.9) pickup drilling so you need to fit the 4.6 pickup and sump AND DIPSTICK.

You don't need to block the old drilling, it's just a "spare" hole in the engine block now!

You might hit trouble with the 4.6 pickup as it bolts to a stud on one of the crank bearings, if yours is a 3.9 it may not have that stud...
