A while back my spark plug blew out of the head, so I Heli-coiled it back in and it lasted 10,000 miles or so. Well it popped again and once I started looking into it, changing out the motor was the best option, not to mention I got the new 04 motor for $185 w/147,000 on it. :D

The dealer told me it would be between $200-$300 to fix the threads and I would still be left with my other two ongoing issues. I have a bad idle when cold that I have been chasing for two years and wanted to update the intake before it cracked. This motor has the new intake and is a PI engine so hopefully has a 20HP bump (we all could use a little more in these cars)


So last night I bought a bunch of gaskets to replace while the engine is out and easy to get to. The following I have and will be doing, if you see anything that I should just avoid or something missing let me know.

-Oil pan gasket
-Oil filter adapter gasket
-Rear main seal
-Valve cover gasket
-T-stat and gasket
-Throttle body gasket
-Water pump gasket
-Exhaust manifolds and flange gaskets
-Autolite platinum spark plugs and some anti-seize
-Engine degreaser
-New coolant and 6qts of 10w30castrol oil w/Napa silver oil filter
-Block heater (600W)

If you can think of anything else I should be doing while the engine is out let me know?
 
Allmost there but I can not figure out if I got all the motor mount bolts or not. Does any know how manny there are?
 
01 is a PI but has the old defective intake on it and only have 4 threads per cylinder vs the 8 on 03 and up 4.6L heads.

I got every thing pulled, 2 bolts on each mount to the frame. Right now I am swapping over parts to make the 04 engine work in my 01. I will be hopfully be installing it tomorrow.
 
Well last night went kind of long, dint get to bed until 3am and had to go to work at 6am but the good news is the motor is sitting in the engine bay all lined up with the transmission and tq converter.

Had to change over the oil pan, pick up tube and pass side exhaust manifold. Along with changing the plugs and putting new gaskets on the valve covers we cleaned up the motor and slowly dropped it in. for the most part it went in fairly easy, dint even have to get under the car to align the trans it was accessible from the top.

There are no bolts in there right now but tonight I will be installing the wiring harness and upper plenum, plus whatever else is lying around that I can get to tonight.

While the engine was out I also installed a Mark VIII tq converter but not before I replaced the Trans pump seal. Since I was using the mark converter we had to swap fly wheels as well. The 2004 valve covers can be used but the motor I got from the junk yard had cracks in both covers so I had to use the old cover, that’s why I’m using the old ones.

For anyone doing the oil pan or valve covers don’t forget to put a dob of gasket sealant where the front timing cover mates to the block because they are not even surfaces and need extra reinforcement.

I’m going to have to do 3 or 4 oil changes in the next few thousand miles because I did not like the color of the crank when I had it open. Does anyone recommend a good detergent to use in my oil to help clean the internals up?

I also had a question about the dipstick, the tube is the same but the 04 had a longer dip stick. So is it safe to assume I just use my shorter one with my smaller 01 oil pan? The 04 looks like it holds an extra qt.

I think you are mistaken about the dipstick tubes being the same.

Checking the Motorcraft site the '01 LTC tube is $22.30, the '04 CV is $21.23. Must be something different.

Why not just move the tube and dipstick to the engine being installed?
 
I got the engine in and running but I couldn’t get the left upper motor mount bolt in, it just wouldn’t align properly. I was thinking about unbolting the Trans cross member so I can shift the whole assembly around to align it. But I just said forget it for now and I will try it again when spring comes around.

We smoothed a few more bumps over and got her running. The only issues I'm having now is two coolant leaks from the new block heater and thermostat housing. I also have a CEL (P1131).

I've tightened both down several times but I'm still getting some small seeping from both. I picked up some new gaskets, RTV, and some more coolant. I'm going to wait till next weekend and try to fix the leaks. They are slow leaks so shouldn't be any major issues waiting till then.

From reading around I got a malfunctioning O2 sensor. Bank one, upstream. Which side is bank one? I have all new sensors and I'm wondering what is the difference from the upstream and downstream sensor. The one's from the factory all look the same but the new one's are different from up/down.

The major "F" up on my part came from the oil filter adapter. I reused the old hardware and failed to see one of the inserts from the old gasket on the bolt. So when I put it back together it poured out, so removed the insert and re-tighten everything. Well ended up cracking it so I had to go to my spare. Bolted it down and all is good.

The car is running well otherwise, no bad idle any more. With the Mark VIII TqC I can feel a small increase in stall speed. I can’t not feel any real performance gains yet. What troubles me is I have been driving a 99 TC signature touring around with duel exhaust and it seems substantially quicker and more torque. Is that all from just the extra exhaust pipe or did those come with bigger gears as well?

I was hoping to get a few more HP out of the new motor but she still is slow. Makes me want to get a cat back exhaust and a tune really bad. But it is nice to not have any more lifter noise!
 
Bank 1 is the right (passenger) side. Cylinders 1-2-3-4 .

Upstream is on the engine side of the catalytic converter, and yes, downstream is on the muffler side of the converter.

Upstream and downstream sensors are not the same.

What did you do about the dipstick and dipstick tube?
