Phase 1 and 2 Bottom End Differences?

[Beaniemoo]

Hi, had a call from a mate of mine this morning who's rebuilding a phase 1 172 engine. He decided to get a second hand bottom end instaed as the damage was pretty bad however the only one available was from a phase 2. He's reusing the head etc off the phase 1 but just rang to say he's got a massive oil leak and did i know if there are differences between the blocks that could be causing this. I didn't know off the top of my head so I thought I'd put it to you guys...

Any thoughts?

the bottom end in my ph2 is the same as the 8v 2.0 laguna engine from 98 iirc.
not sure about the ph1 but cant see them using a old bottom end for the ph2 but a newer one for the ph1? not 100% but could help.

there's nothing that would cause a problem. Plenty things that could leak if not put together quite right though
