help! loud metal to metal knocking noise

Contour Enthusiasts Group Archives

Here's the deal:

96 Contour, 5spd

All cylinders have good compression
Oil looks grey and thin
Sound seems to be tied with cyl #2.
Without ignition sound is minimized.
Doest not appear during cranking, only when engine is running.

Motor came out of running car with 90K on it, maintained very well swapped from a donor car.

Let me start by asking, what do you mean by that?

Without the plug wire on it, the sound isn't there.

little more background while I have the time. the car is a 96 se I got with a blown headgasket, but the car still ran, I tore it out and swapped in a 2.5 from a 96 contour I've owned for 4 years and not had a single problem with. Car drove great for 45 miles and then started this problem. It died ont he highway when I pushed int he clutch and didnt want to restart. when I got it towed home I ripped off the intake and valve covers and nothing was out of whack. so we ran it with them off and started testing things. first thing i noticed was that it woulndnt start with the intake on but it starts and runs everytime with no upper intake, or throttle body attached. All injectors are spraying even. Noise doesnt go away when unplugging a certain injector, but without the #2 wire on it the noise is gone. also had 160's compression across the board

Sounds like rod knock. Pull off the pan and have a look see.

yeah thats tomorrow nights fun....
