2 new problems....

The 1G was fairly uncommon... an underdog of the MKIII world. They're definitely a rev happy engine with decent (but not phenominal) potential with some upgrading. I don't think that engine even made it to Europe. There has been a lot of speculation about how much power they're capable of, but the few people who've tried building it here in North America have all bailed on it. Parts aren't easy to source, they're expensive to ship in and the 1JZ and 2JZ offer greater gains from the same amount of work.

While a BHG is not big concern on the 1JZ, 2JZ and 1G the potential always exists.

Oil leaks on the top (upper half) of the engine are most likely coming from loose valve covers, dried and shrunken seals (such as the one on the CPS or dist. or cam/valve cover seals), or cracked hoses.
