Thanks for all that info. I got everything apart fine and was able to move it.
This last week I started taking things apart and cleaning with a tooth brush before moving it to the engine stand.
One thing I'm wondering about: The oil pan is off and as i'm sliding the block along a wood deck I see the pistons pumping, I'm guessing from air coming through the bottom? This wouldn't mess up the timing would it? I set everything properly before splitting up the heads and the crank wasn't touched.
Re: Parts, it's been tricky, I don't know if it's just because of the Phase II 99 status still having the EJ22. Kits don't seem to have all compatible parts. Seems like the water pump and belt are different between 2.2 and 2.5 but everything else is common? I'm just ordering everything separately-Stuck with Aisin, NTN, and Mitsuboshi for the belt (a little harder to come by).
With seals it's really weird and that's why I came back to ask, I kept finding a complete FEL-PRO gasket set at Amazon and Rockauto with the part number: HS26415PT-1 that didn't include the 1999 year, searches weren't producing anything else so I contacted Fel-Pro and they pointed me toward HS26415PT, problem is there's a couple of negative reviews online stating that kit does not fit the Ej22. Not sure, but if anyone has any ideas? Osei?
