Well my 1st cylinder is leaking in my 95 pontiac sunfire and it needs a new head. So im gonne get a new engine. I have a 2.2l motor atm, and I was thinking about putting a 2.3, 2.4 or a 3.1 from an older cavalier. Does anyone here have experience with motor swaps or have any idea if any of those motors would mate up with my current tranny. Ill have a friend that always swaps out engines and transmissions helping me. Im just trying to do a little research first.

Different bellhousing on the 2.4 and you'll have to have the ecu and wiring harness for the 2.4... Might wanna think about sticking with the 2.2 (as they are more dependable motors and the parts are far cheaper... plus there are far more upgrades for a 2.2ltr than the 2.4).

well...you definatly supported your name in that post

I've been around my fair share on Cavs, Sunbirds, and Fires

If you got the tools and will, just get a reman head and slap on there.

Oil fouled plug in first cylinder, that means seals or rings are bad rings no?

you can buy rings for just one piston if thats the case.

Take the head off. Drop the oil pan and remove just the one piston right in the car.

If you buy a reman engine plan on $1600+ for the engine, $1000+ to have it installed.

If you are capable, grab an engine from a respectable yard. Ive done this 2 times and a third engine from E bay believe it or not. No problems on any of the 3.

I'm definately with Ryan on this one... Plenty of 2.2s around in really good shape... Heck might even wanna check out the local papers and such for someone getting rid of a beater (runs good looks like crap).

Stick with the 2.2.

The 2.3's and 2.4's are just absolute pieces of junk imo, as are all the 60 degree motors...

x3 what Ryan said. My engine took a dump, and i got a used one with 65k on it, and i havnt had any problems (besides a bad hose, no big).
