Engine removal on a 1990 2.9 auto 4x4

[cardana24]

okay, an update....the engine is out. Oh my lord, now I realize you only need to take the top nut off on the mounts to get the engine out I took several hours trying to get that lower one off. Then I un bolted the mount from the block, and once I pulled the engine I realized I did not even need to do that. Also some else that I found helpful is to pull the Transmission dip stick tube out, it really gets in the way of one of the trany bolts.


Now I have a few questions. The engine I am putting in the ranger is from an 88 and it has an egr tube coming out of one of the manifolds. But the truck I am working on is a 90 and it does not have an egr tube. Am I missing something? Does the 90 not have an egr system? If not I will remove the tube and plug that hole in the manifold. Anything else that may differ on the two engines I should know about?

One more thing. What is different with the y pipes? I cut the old one and need to get another one. Which one do I need? I am guessing the one for the 88, is the rest of the exhaust the same other than the y pipe? If so I will get the one for the 88. Thanks for any help.

I'm sure someone can correct me here or verify it but I think:
the 90 probably does not have an EGR tube, but it probably has a block off plate where it goes? If that is so, you will need to transfer from the old to the new.
Now the Y pipe...I'm not sure why but if you look up an '88 and a '90 you will indeed find 2 different part numbers...I honestly don't know why..I'm sure someone here will have a clue?

On a different note: Pete...the dual set up out the muffler is pretty much what I had in mind...only other option would be splitting it after the cat.

I will check the block off theory out.

With the Y pipes it is wierd. Do both the 88 and 90 use O2 sensors? That's the only thing I can think off. On partsamerica the walker Y pipe is listed as two different part numbers. But if you look at the Y pipe made by Maremount the p/n is the same for the two years. What gives?

 

[RangerAx]

Okay...I *think* I have an answer for you...
I just took a second look and found that between the two, it seems 2 different CATs are used...based on what I saw , they likely have a different flange where the Y pipe attaches and that would explain why there is 2 different Y pipes.
On a side note..be careful about part numbers on PA's web site...if you look up the manifolds for example, you will see one for Motormite and one for Dorman, both listed as right side, both with the same part number, but two different prices and slightly different warranties. Oddly enough..Dorman and Motormite are the same company.
Any who, I found basic diagrams by looking at Maremont's website directly (maremont.com) and they seem to show one CAT with 2 dual inlet flange and the other a single.

so if I follow what you are saying, the manifolds are the same so I should get the pipe that is made to fit the 1990 exhaust set up...correct? Again I am putting an 88 engine into a 90 ranger.

 

[RangerAx]

I wouldn't go with my word without checking and double checking it but...
no...you're putting a '90 engine into an '88 true, but, assuming I am correct: the exhaust system you're dealing with is basically the 88's. That is, I think the manifolds are the same, but if the difference in Y pipes relates to the CAT as I guessed, then you need the Y pipe that matches the appropriate CAT, which in your case would be the 88'.
(I was hoping someone else could verify my findings..like AllanD, or MAK).

you have it backwards. I am putting an 88 engine in a 90 ranger. I think the difference is in the cat converter set up because the manifold part numbers are the same but the cat numbers are different. Also I noticed that the manifolds are not exactly the same because the 90 does not have a port for the EGR...there is not a block off plate or anything just no hole at all. Sice I am not going to risk breaking off one of the exahust bolts I am just going to stick with the 88 egr exhaust manifold and block the egr port off some how.

I ordered a y pipe for a 90 ranger today.

 

[RangerAx]

AH my apologies then..amongst the sorting out I flipped myself around. As for the manifolds...good to know.

 

[cardana24]

Any suggestions on plugging the hole for the egr port? I assumed I could take the fitting off of the manifold but I was wrong. It's so rusted on there I cannot get it off. I don't have a welder...I know that would probably be the first choice. Any other ideas?

I am probably going to put the new engine back in the truck starting on Wednesday evening.

 

[cardana24]

okay. How do you know when the torque converter is in place? This is my first time working on an automatic. I read that you turn it while pressing it towards the tranny and it will make a clicking noise and once it stops clicking its in place. Well I am not sure I have gotten to that point. When I wiggle and push on the torque converter it kinda clunks once, and moves towards the tranny a little then I wiggle more and it clunks again and it moves a little more towards the tranny. Now I have tried to wiggle and push it further but I am really not getting anywhere, and I am not sure what I should be feeling for. Now when it spin the tq converter clockwise (while facing the tranny) I just get kind of a sound like marble rolling around on a sheet of metal...or kinda like a ratcheting noise, when you spin a ratchening wrench the opposite way...but I am not feeling any resistance, and I still have not heard anything I would describe as a click....can someone please let me know how to do this right? If it matters I never took the tq converter off of the tranny when I removed the engine, I only unbolted it from the flex plate.

The only thing that I can really think of that you might try is a simple marine plug from the hardware store, or make a trip to the j/y to get the approperiate plate.

If I remember right, it should click in 3 times, but it's been a long time since I've been there. When I put it back on, it had slid off from not being jacked up high enough, which I just pulled it off and let some of old the fluid drain out of it.

When you say click, could it sound more like a sound of it seating...or a clunk. I would not describe it as clicking...so that could be throwing me off.

Yes, it is clunk/click.

Okay I should be able to work on the truck some tonight. Where can I find a picture of a stock ranger engine bay? I need to make sure I put back all of the brackets and braces on correct for the acessories.

Also does anyone know if me not using the oil level sensor is going to mess up anything performance wise or will the oil light just stay lit up?
