Hey guys, I am new here and I just picked up an 01 Expedition. It has a 4.6 engine...but it has problems. The CEL is on and, it came back with three codes. P0353 Ignition Coil C primary/secondary circuit malfunction, P0303 cylinder 3 misfire, P0304 cylinder 4 misfire. Tonight I did a compression check on the right side of the engine. Here are the results:
4-180
3-0
2-180
1-300+
So obviously I have a problem is cylinder 3. The spark plug on cylinder 3 had the end of the strap missing. Not sure if that cause the problem or if the head gasket is blown. There is no compression on cylinder 3 at all...the gauge does not move at all when you crank the engine (normally on other cars I have tested with blown head gaskets the normally register some pressure). Also, I should mention that it looks like there is oil in the coolant.
What would cause extremely high compression pressure on cylinder 1? I have never see this happen before. The engine turned over probably 5 or 6 times and by that time it had jumped up to over 300 psi. So I took the compression tester out and then re installed it just to verify the results and the same thing happened. What would cause this?
So what long blocks will fit in an 01 expedition? Will any of the E150 van engines work, or the F150s? I know I need a Romeo engine, but I am having trouble finding out if any other long blocks will work.
Thanks for any help.
