: Quick engine swap question

I currently have my 94 vin Y northstar powerertrain sitting in my driveway in front of my eldo. It has a blown headgasket. I also pulled the powertrain out of my totaled (rear ended) 94 STS which had a vin 9 engine.

My plan is to swap the engine, tranny and PCM... But my question is, should I also swap the ICM?.. if so it means I have to dig through the garage for it... not too big of a deal, but I would rather not have to if I know swapping the ICM doesn't matter.

Nevermind about my question. I found the icm that goes with the engine I'm putting in the car and I'll use that one.

But in the meantime here's some pics of what I'm doing for you all to enjoy.

I had to add a personal touch to the valve cover. The silver powder coat was coming off and it looked ugly before painting it.

Here's the old powertrain sitting on my dads handtruck/dolly... When I'm done with the whole process I'm probably going to owe my dad a new handtruck. lol

The emptiness that is now under the hood.

Might wanna think about timeserting the engine you are putting in, so it doesn't suffer the same fate as the original.

Good point - I just assumed that was an automatic, but thanks for bringing it up, in case he wasn't planning on it

I dont have enough time or money to do that kind of work on it... I need the car operational asap. I will save the engine I'm pulling out and see about getting it timeserted though.

I'm done assembling it on the cradle at this point, so all i have to do is put it back in the car now. Pics to come soon.

Personally, I would never install or re-install any pre 2000 N* engine that had not been inserted, but that is me; maybe some people think it is no big deal to remove and install these beasts, but I would avoid the possibility at all cost.

Sorry about not getting any more pics untill now... I was in such a tight time-schedule that I was just focused on getting it up and running. I got it running last Tuesday. Surprisingly, it started up on the first try! It idled at about 3k rpms for a while at first but then I discovered a couple vacuum leaks. After that I was getting a slight misfire on the 4 cylinders in the rear bank, but no codes. I went into the PCM Data displays and looked at the O2 sensors. Sure enough the rear bank O2 sensor was giving a bad reading; it was reading that the fuel mixture was too rich and because of that the PCM was leaning that bank out to the point of it misfiring. After changing that everything is running absolutely beautifully!

I already drove the car over 200 miles with this engine and it's awesome. I love the power increase!

The car's not going to live for much longer anyways. Right now I'm only trying to squeeze a few more years out of it so I can graduate college and get a better paying job to get a new car. It's a great car and i love it, but I already made it live for 7 years after an awesome local auto shop named Ignacio's Auto Service (which I now work for) said to throw it away and get a new one.

Good job. What color is the car - Calypso Green? I leased a Montana Blue '94 Eldo and then bought a used '94 Calypso Green Eldo that I had a lot of problems with. I traded that one in on the '97 White Diamond ETC I bought new and still own.

Is that a transmission cooler I see? That's where I put mine, except my lines go to the right. Oh, wait...maybe that is the engine oil cooler on the earlier models? I never saw one before, since my '97 has it inside the radiator end tank, but I think I heard that the earlier models had one that was external and separate from the radiator.

I seriously thought it was a tranny cooler when it was on the STS as well. But, it's actually for the engine oil. The engine oil has the cooler in the radiator side tank also. So the oil is double cooled. lol

well would you look at that! that's my cherry picker!!!!! it looks like you're using it to lift the car, but that's the same one i have! mine is a complete shade of rust tho... i've never seen another one like it and i'm glad it's not alone in this world!!! lol. my uncle gifted it to me when i was building my first engine at 15yo. i don't know how old it is, but i'm guessing 70's at least! funny stuff.

That's exactly what he did - lift the car off the drivetrain - the whole enchilada comes out the bottom.

It's all in the first set of pictures...........worth a thousand words.

Nice job Krashed989, that cherry picker actually lifted the car high enough to get the motor out? How long did it take? I may have to tackle the job myself my 98 STS is starting to act up again and the head gaskets were already done once.

If you're going to do it, i'd stud it with Jake's kit. I'm waiting for mine to come in the mail. then it's buying the gasket kit with seals, and the FSM

Lift the front end with the cherry picker and lower the cradle onto a rented pallet jack.
