It has been a couple of years since my SX/4 broke down. I thought I started a post showing what I was doing with the engine. I guess not. I have been dealing with financial issues, and several short military activations. I am back to working on the 2.5l Iron Duke, So If anyone is interested, here goes.
I took photos of the project when I started. I will post those when I get a chance. The rebuild started with a cam gear tooth failure. Dang those fiber gears. As some of you know, the cam gear is pressed on so you have to disassemble half the engine just to get the cam out of the car. Well that is what I did and turned out to be a blessing in disguise. The bottom of the cam bearings were pitted and the center of the lifters were pitted. So I pulled the motor out of the car. Upon complete teardown of the engine, found the fuel pump lobe on the cam was damaged scored pretty bad, the bottom connecting rod bearings were pitted, the bottom Crank bearings pitted, The car only had 69,000 original miles when I got it. the pitting may have been caused from the car sitting for so long, the oil squeezed out from between the metal allowing two different types of metal to contact each other, electrolysis, pitted metal.
