yup but 99 dont have IMRC in the lower intake to help with low end torque and it lacks the 3 extra hp

I know that, but 3 hp...are we that power hungry for 3 hp?

no but its a more efficient basis to start modding on the the 99 lower intake to be honest lol i am correct like i said before tho the only ppl who will notice 3hp is the Amish cuz they will have 3 more hoarse to blow there field with.

"its when you keep the 99 pcm and use the 02 engine is where ur going to run into sensor and running issues."

I suspect the opposite is true. Correct me if I'm wrong, but I believe the 99 block and heads are the same as the 02. In that case if all the sensors and electronics from the 99 are used all should be compatible.

Trying to use the 02 parts with the 99 ECM certainly could lead to a problem.

With the engine out of the car it would be easy to swap the intake manifold and associated parts and I would think the manifold gaskets would be cheaper than an ECM.

That's how I would do it, but I guess one could go either way.

no u can grab the pcm at the same time as the engine and they probably wont even know u took it, #2 "Trying to use the 02 parts with the 99 ECM certainly could lead to a problem." thats exactly what i said dude so why say it again and #3 i know all the shit is the same i did the research thats why im saying just swap the PCM and the engine. like i stated above i looked into it. and #4 why the hell would u pull the fuckin intake off the 02 engine its better then the fuckin 99 its already installed u dont have to fuck with it u dont need to buy a new gasket and either fuckin way he will need the 02 PCM so shut up already like i said put the 02 engine in use the 02 pcm to make sure it will 100% run properly. the sensors are the fuckin same and AGAIN y the hell would u go through the pain in the ass of the intake swap then u have to disassemble clean reinstall re torque and all that shit. and oh did i mention the 02 intake is a better intake. please dude read first think after then open ur trap cuz im getting tired of repeating my self.

From that standpoint yes your right, but from a power standpoint it really doesnt matter. 3 more hp isn't gonna win the race.

100% agreed unless ur racing lawnmowers but if he has the option which he does keep the 2002 intake on the 2002 engine its just a no brainier.

"and either fuckin way he will need the 02 PCM so shut up already like i said put the 02 engine in use the 02 pcm to make sure it will 100% run properly. the sensors are the fuckin same and AGAIN y the hell would u go through the pain in the ass of the intake swap then u have to disassemble clean reinstall re torque and all that shit. and oh did i mention the 02 intake is a better intake. please dude read first think after then open ur trap cuz im getting tired of repeating my self.[/quote]"OK

Well I don't mean to ruffle any feathers!

But, as far as I can tell there were major changes to that engine for 99 and a minor change in 01, which is what you are talking about. The 01 change seems to involve only the intake manifold.

If that is the case then your statement above is not true. One could use the 02 engine with the 99 manifold and the 99 ECU.

I totally agree that if you use the 02 engine as is you need the 02 computer.

So I still stick to my position that unless he wants to install an 02 ECU he should use the 99 manifold.

BTW this is supposed to be a forum for dicussion. I believe one has a right to express an opinion and defend it without invoking a string of profanities.

[Juggalo_X]

srry i dont know wut happenedto the quote WTF?

[tomzac]

Oh, BTW, the coolant sensor is in a different location on the 02 motor. It's in the back of the head (pita to get at). Where as the 99 is in the lower intake.

[elmills]

Thanks everyone for the input!

I went to look for an 02 PCM and the guy at the parts place knew exactly what I was trying to do. He is a Mustang fan, too, in fact he has built several fox bodies.....anyways he said that the PCM will be expensize and to have it flashed would cost a couple of hundred bucks. Another guy at the store was getting the same thing done to his Mark 6. He said all in all it will cost him about $500 when he's done switching out PCMS.

I've already bought all gaskets (minus the head gaskets because that would make me feel like an ass for buying a salvaged 02 engine when all I had was a blown head gasket in the first place )

I'm OK with cleaning my 99 intake and dumbing down the 02 motor.

Juggalo_X: Thanks for your help, but it sounds safer and easier to take my 02 down to block and heads and use all 99 components. I think I have all torque specs and materials to do this .

The 02 engine was sitting right next to a 99 engine at the salvage yard, but the 99 looked rough, and the 02 was gleaming.

I plan on taking the 02 down the block (with heads still attached) I will clean everything I can. I may even vat the intake if I have time.

Honestly guys, I have to get my car back on the road ASAP.
I will update everyone on the progress of the swap and may ask for guidance from time to time, but I am prepared to break both engines down and make it work somehow.

if your willing ot do the work then go for it, just to much of a pain for me lol im still wondering how u blew the head gasket they are a pretty solid engine.

OH NO, what will you do without those 3 extra ponies.

Good luck and godspeed.

[elmills]

I'm not sure....I had a ford certified mechanic look at the engine and he said that he was almost positive that the head gasket was blown.

Let's go back to 40K miles on my 99 mustang. The check engine light comes on. I take it to ford (still warrantied). They read the code to be Misfire in 6. They replace my block.

At 107K....I get a check engine light.....I take it Autozone and they read it and it says Misfire in 6. @#$@

I take it home and do a compression test. It reads 80/120/150/180 for 1-4....5 reads 80/100/120/150....6 did not read at all.

I tried to turn the engine over on 6 and it wouldn't. It sounded like it was starting, but not turning over (it's real hard to explain the sound, but I can tell you that it wasn't a dead battery sound.....it really sounded like the engine was trying to start without the "turn over" sound)

That was when the mechanic came over and looked it over. He said there was coolant on the dipstick. I cranked the car and he listened to it and he said that it definitely sounded like I was running on 5 cylinders. Then he said blown head gasket or worse.

That's where I am right now.....I will figure out what really happened this weekend, I'm sure when I take apart the 99 engine.

coolant in the crank case could also be a intake problem. but your lack of compressions is either valve related or a head and or head gasket problem... maybe your head is cracked.

[elmills]

That was the "worse", the mechanic mentioned. He said that if I were to replace the head gasket, I should send the head in to check for cracks.

He said that is where the job would start to get expensize. That was when he mentioned that if it were him he would buy a used engine and just swap them out. He said (and not to offend anyone here)....it's just a V6...they are cheap at the junkyard.....just replace it and be done with it. He also said that the later model ford V6 engines were prone to head gasket problems.

ford diesel engines are prone for head gaskets beleive me in my coop period at the dealership i did about 10 all with onder 100 000 kilometers on them

Interesting. Sounds like a good call to replace the engine. Hole in a piston maybe?

My only experience with this engine was doing a valve job on my wife's 99 Mustang V6. The problem was excessive pinging and power loss. What I found was that #6 and #3 had major carbon buildup on top of the pistons and in #3 the plug was damaged from preignition. I scraped all the carbon out and reinstalled the rebuilt heads plus cleaned fuel injectors and it runs like new again. So I think the problem in these engines with #3 and #6 cylinders is due to preignition.

I since found an article on the internet that says it has to do with the baffle design on the left valve cover for the PCV system which allows too much oil into the intake. That's why I suggested using the valve covers off the 02 engine. They are supposed to be of an improved design.
