Fire it but point it my way!! Hahaha!
Picked up my rod bearings at lunch today. Going to have to get the wagon back in the garage this weekend to do this while the storms rumble outside.
Out of cuiosity, I pulled the IAC valve off my SPI and noticed it is almost exactly the same part as the Zetec. What's the word on swapping these out? Looks like the main difference is the clocking of the connector is turned 90°. However, I am feeling that perhaps the IAC isn't mush of an issue right now. The car is running well aside from the bearing noise when it is cold. Idle is pretty good but it roams a bit like it would if it had a MAP sensor that was bad. I just read that a clogged PCV valve could also contribute to a bad idle. It's cheap enough and I didn't change it before when I should have....
Boom, parts cannon.
Ford IAC valves are electrically the same, they will probably swap.
Vacuum leak for the idle?
Checked all over for vacuum leaks, found nothing. Only thing I suspect is a fitting on the bottom right corner of the intake. Looks like an odd plastic pressure relief valve or something, so I 'll have to look that up just to see what it is. BUT, the idle seems to be consistently steady now at 900 rpm without me doing anything to it. It seems that it is all improving the more I drive it and wonder if this is an "learning" pcm and that perhaps since this one came out of a jy and sat with no power for so long that it just had to reset all of the parameters and get it all to sync up. I have still yet to throw any engine codes and it is running very well.
I am holding off on tearing into the bottom end for the rod bearings. I am not 100% convinced that they are the culprit at this point. I am beginning to wonder about the VCT solenoid. It seems as though all of the noise can be heard more from the head rather than the bottom end. Even though I had this head surfaced, I did not have it rebuilt or reset the valves. I removed the cams and followers from it and put them all back exactly the way they came out. It seems as though higher mileage zetecs seem to be kind of noisy and the solenoids can fail so I will be looking that way before anything else right now. I would do the VCT delete, but I do not want to have a CEL on the dash and do not want to have to reprogram the pcm from stock. It worked right when new, it can work right again the way they designed it. (did I just say that? that doen not sound like something I would say....)
Anywhoo. I am getting more comfortable with the swap overall now that I have put some miles on it. It cruises down the highway like a dream and seems to be a nice little package. I just have one small coolant leak from the thermostat housing to deal with and still need to reroute my wiring from the low pressure ac switch and the washer pump. Probably throw some euro turn signal repeaters in while I am in the vicinity....
Computer shouldn't take that long to learn but if the engine is doing better then cool. Usually when I would unplug the battery to my mustang to do whatever repair I needed to it would take maybe an hour or two of driving until the computer settled into where it likes to be.
Officially for sale!!
Good Luck! I was just in Laredo......
Oh man wish you were closer. Stick wagon with cruise and a/c is my favorite combo!
