this is a huge job. you can go about it 2 ways, one way is to pull the motor out, the other way, is to drop the subframe and pull the transmission out. either way, its a huge job. this is something that would take a trained professional who knows every nut and bolt on the car, a good 8-10 hours to complete. if your willing to do the job yourself, the seal is located on the end of the crankshaft behind the flywheel/flexplate. you will need to remove the flywheel in order to get to the seal. the seal is mounted in a removeable plate.
a 1999 has a 1.9l Dohc
No, A 2.2L OHV will NOT replace a 2.4L DOHC engine.
Not Applicable The Saturn 4 cylinder, both the SOHC and DOHC used a chain, and it doesn't need to be replaced unless the engine has OTHER problems.
I believe the 1.9L is an intereference engine for both sohc and dohc. The timing chain is good for 150k miles or so before I'd replace it unless you hear it rattling around in there.

The 2.4 litre DOHC engine is NOT an interference engine.
nothing. only if it is a dohc or a sohc.
Oil capacity for your 1999 Saturn DOHC 4-cylinder motor is 4 Quarts of oil
yes, all the Saturn DOHC motors are interference engines.
4 Quarts
Yes, but is may require the use of the intake and exhaust manifolds from your 1997 engine. The headers to be reused will need to be milled flat by a machine shop to ensure they are flat and will seal properly. I have a 1994 SC2 running a 1998 DOHC engine from a wrecked SL2, runs like a champ, but I did have to reuse my 1994 manifolds. Good Luck
1.8l dohc
If they are both dohc, then yes. If the older motor is a sohc, then you will need to change the wire harness and computer...possibly other components to make it work.
