The #1 cylinder wall ended up having a crack in it, so my 2.3 is no good. Oh well, at least I didn't pay much for it. If I can't find another 2.3 I'm going to just rebuild the 2.5.

It looks like I will have to decide on this fairly quickly though... About halfway to work yesterday morning, while climbing a long steep hill, the motor made a loud pop noise and died. I got it pulled over to the side of the road and luckily my boss was right behind me when it happened. He stopped and helped me push it to a gravel turn off so that it wasnt parked so close to the road. I called a tow truck to take it to my parents place and haven't had a chance to check on anything yet. After I got it pulled over, I tried cranking it to see if it would start. It sounded like it didn't have any compression. Kinda like a rig with a timing belt sounds like after the belt breaks.

Hi guys! I'm back!   I never did find another good 2.3, so I'm having the duke rebuilt. I finally got it pulled out of the car and took it to Precision Engine in Moses Lake. Before I took it in I did a partial tear down and this is what I found

Pretty typical for these motors, the steel gear on the crank eats the plastic cam gear. The cylinders still have decent crosshatching in them, so I might be able to get by with just a hone. It has definitely been out and gone through before. when I bought the car, the previous owner gave me this with it

It's an offy intake for a four barrel carb. I figured I might as well use it. I'm planning on using an adapter and mounting a Holley 2 barrel. I should hear back from the engine builder by this weekend and find out what it needs for sure.

Good to see that you're plugging away on the SX/4.  I don't have much knowledge on the 4 cylinder versions but have had my fair share of 6 cylinder AMC's over the years.

The Dookie is a Chevy motor that's just a bit better than their 2.8 V6.

I heard back from the engine builder last week. He gave me a quote for $4300. It needs pretty much everything.
On the head:
New valves, valve guides, seats, mill exhaust side, and mill the head gasket surface. New rocker arms and push rods.
On the block:
New thread inserts for the head bolts (old threads were damaged). New cam gear. Resurface and balance the crank. New bearings. Bore the cylinders.
All new fasteners throughout.

All that, and he'll assemble it and dyno it for me as well.

Couldn't find one. I found a company that sells reman 3.0L mercuisers for $2600. But at that point I owed Precision  $1200 for what they'd already done, and with shipping it would be close to $3000. So any way I looked at it I was gonna be out $4000. I'd rather support the local guy anyway.

My new clutch came in on Friday!




Last I heard from my engine builder, it should be done by the end of the month. I'm really excited to get it back on the road! Its been sitting for over a year now.

Your sx/4 looks very close to mine. Mine is white as well. Mine has the rear spoiler, guage package on the floor, automatic transmission, electric windows and other options. My interior color is black.
