Engine Swap (with story)

[Chrisssssssss]

Hey all,

So I ended up buying that 93 Green MTX with 100K on it, and I got it home and it blows tonnes of blue out the tailpipes under load and if you blip the throttle at idle. It also rattles like a diesel.

I pulled the valve covers, and first off, the plugs were completely fouled, the plugwells had much oil in them, and the valve lash was very far out. I thought that since the car was sitting for a while, maybe the valves were sticking, so I tried some products that cleans out the engine and frees sticking valves, and also tried tranny fluid to completely wash out the engine.

I took it for a nice long spirited drive and was redlining it a couple of times, and it seemed to be getting better. It did not smoke quite as much, and it looked like things were settling down, but as I drove the knocking was not getting any better. I came to the conclusion that the motor has bad piston rings, and I would try to drive it a bit and maybe change the oil for the high milage kind, and see what happens over the next little bit. As soon as I said that to my buddy that was along for the ride, I was just babying it back to his car at the time, then I heard a bad backfire and then the motor started to rattle really bad and as soon as I put the car in neutral it stalled.

I then got it restarted and limped it back to the garage that I will be doing the motor swap. By the time I drove it there, it sounded really bad. Something let go inside the motor, I assume it was a ring.

Anyhow I just thought that I would give you the background before I go any further. I am going to take the 3.2 out of my high milage '92 to put it into the much lower milage '93.

So I am hoping to have it done over the weekend and see what happens. I have about 5 days to do it, so I think that I can get it done in time.

I will keep you posted on the progress. Wish me luck.

Good luck with the swap. thumb
It sounds like you spun a bearing in your motor. BTW why did you put transmission fluid in your engine shrug

 

[Freak SHO]

Best of luck, bro.

If you get it done in 5 days I think that's pretty damn good...maybe even a record.

This is the place to turn if, (when), you need advice/help.

Make sure to curse a great deal, and drink many beers...

That's not the first time I've heard of using ATF as an engine flush. I don't know if I'd do it myself, but I have seen others do it. Supposidly the detergency of good ATF is pretty high.

Very similar to my sob story cry . Mine stalled as well then restarted and sounded like ****.

It's not a 5 day project. At least if you've never done it before. I'm 4 days into mine and it's going VERY slow. Granted i'm only working 3 hours a day on it but my advise...take you time and photograph everything you can.

ATF does have lots of detergent and cleans out gummed up engines quite nicely. I've done it with good results.

There are a few of us that is going to do this swap. I **hope** to have it done within 5 days, but I am not sure if it can be done that fast. I have done it before and did the 3.2 MTX swap, but I am not sure how fast this is going to be. I will keep you guys posted.

I used ATF for it's detergents to clean out the engine. not sure if it helped, but I will tear the blown motor apart later. I am planning on stripping the internals, cleaning it up real pretty like and turning into a glass topped coffee table.

Awesome idea, I'd love to have that table, not sure how well it would go over though...

I have heard of people using ATF for cleaning also.
