The V8 Owners Forum -

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

So I think you must use the 4.6 pickup pipe. The hole in the block should be open, and I believe that the oil gallery at the timing cover end is blocked off by the casting.

thanks!

I only blocked the 'old' pick up hole. But when it is also blocked at the timing cover it shouldn't be a problem I guess
