Interesting information...

I've been looking at pictures of the Sonata oil pump side by side with pictures of the Monty oil pump and I can't really see any differences. Until they are side by side though, it's really hard to tell. If they look the same in person, I may just stick with the OEM Sonata pump.

Are the oil pans appreciably different? If they are not, it may make sense to just use the Hyundai oil pan and not even open up the bottom. I'm expecting them to be very different being FWD vs RWD though.

Good information on the Distributor too. Thanks Dave.
