I talked to the wrecking yard last night and it now looks like Thursday or Friday of this week motor #3 should in.

Don't use that cork oilpan gasket, they are known to leak. I bought a tube of OEM Toyota RTV for around $11 or you can also use off-the-shelf gray RTV.

I went to the wrecking yard last night to give them back Motor #2 and pick up Motor #3 and look what I found when I got there.....Two motors.... So I got to choose which one I wanted.



Well I never seen the intake on the left one so I grabbed that one. What can I say, I like oddities....Plus I'm still not sure which intake I'm going to use on my next go around.... It also looked just a tad cleaner than the other one.



Well now its time to tear it down and see what it looks like on the inside! Come to find out this intake had two butterflies in it and two TPS's??? Strange..... But it looks pretty clean on the inside of it, so thats good. I'm going to have to do some research on this intake because the more I look at it, the more questions I have.....



Inside the plenum also looks clean......



The EFI Runners look pretty clean...



So now we are down to the intake side of the head and it starting to look more what I expected to see..... more build up of crap in the head. But for this engine it still looks pretty normal to me. and all the cylinders look the same, which is a good thing!



And here is the exhaust side. It does have carbon build up but to me again it looks like a normal level of build up and every cylinder looks the same.



Time to pull the water pump. Much cleaner then the last one but I was surprised to see some build up of sediment in the right side cavity.......... But atleast this one actualy had soem coolant left in there.



The Timing belt, sprockets, tension look to be in good shape.....

The inside of the valve covers look kinda crappy! just more burnt oil build up than I expected to see.



The valve train looks good....



Well now for the time of truth! Time to pull the HEAD!



#6 cylinder head gasket is BADLY deformed, two spot pulled in slightly and one spot really pushed out. It doesn't look blown to me and the metal crush ring is still intact but it would have NOT lasted very long in that condition!



#4 & #3 look acceptable.......



#1 is also BADLY deformed and it was even to teh point wher teh piston was starting to hit it. But again it doesn't appear to have actually blown, YET.....



And here is what the valves look like. Much better than the first two motors.



Well, right now I'm not sure what I'm going to do. But I really don't see anything here that I can complain about other then the head gasket was on the verge of blowing. But thats not a big deal since I pulled the head and had plans to replace that anyways. As long as it had NOT blown and damaged the bearings in the bottom end, I should be fine.

I think what I'm going to have done is a professional Head Job, Send the injectors in for a cleaning and maybe inspect the bottom end bearings. But I hate disturbing the bottom end since that would probably void teh warranty I curerntly have. I should cost out the price to have the bottom end fully checked out and balanced also.....I just have to think about it some more before I do anything.....

For those that are interested here is some good info on trying to convert a shorty straight 7M intake to a long Y-Pipe intake.
http://www.supraforums.com/forum/showthread.php?t=309728

Basically Cressida's and Tubro Supra's have a shorty straight intake like this:


And N/A Supras have a long Y-pipe with a plenum that is equipped with ACIS (Acoustic Control Induction System) and look like this:


I'm still not sure which intake I'm going to use but I'm thinking I will use the Supra Y-intake and plenum with my Cressida Thottle Body.....

The oddball intake plenum and two butterflies control the traction control system; something I never knew the JDM 7Ms had. When slip is detected by the wheel sensors, the ECU closes the second butterfly to reduce engine power. Unless you have the JDM ECU, I wouldn't use the TCS manifold.

From my understanding so far, the TRC system is rare even in Japan for a 7M engine. right now I just want some info on it. I would like to use it for the oddity factor and just disable the second butterfly.



I'm still trying to identify this strange intake and I started a post over on Supra Forums directly related to it. So I thought I would post a link to that thread. Hopefully the guys over there can figure it out. I've also called a Toyota Parts Guy and he is working on it for me also.

Heres the serial number on the block - anybody got a reference sheet by serial numbers??

7M 0381113

And here are some part numbers off the odd parts.

Thorttle Body
22030-42020

TPS's (both of them have the same numbers)
89452-14050
198500-0241

TRC device (I have no idea whats it really called)
89632-30020

Can anyone look up those numbers in some master toyota parts list???

I got the head back from the machine shop yesterday from Motor #3.









This motor didn't look like it had very many miles so I didn't have a "complete" head job done with grinding the valves and all of that.

What I did have them do is:
* Dis-assemble the head
* Hot tank it to clean it all up
* Remove the broken exhaust stud
* Surface the head (took .012" off to clean it up)
* Install new valve and cam seals
* Re-assemble the head.

That cost $95 so it wasn't too bad. But atleast now I know its all in good working order and nice & clean.

That was a good price for what was done. I paid more than that and still ended up doing the valve stem seals myself.

Well I worked on the 4runner all weekend long!

Friday night:
I basically got everything removed from the front of the engine bay. (grill, winch, fan, radiator, power steering, alternator, water pump, distrubitor, charcoal canister, coil, afm, etc...)

Saturday morning:
I finished preping Motor #1 to get it pulled out of the 4runner.

Saturday afternoon:
I got motor #1 pulled and set onto a motor crate in the garage. I also got the garage organized so I could transfer everything from motor #1 onto motor #3, which was a BARE short block on a engine stand.

Saturday evening:
I started assembling Motor #3 and I wasted a lot of time trying to adapter that Import motor Y-intake and plenum to use my US model Cressida Throttle Body. In the end I decided it was more work that I wanted to get involved with and just decided to install all the US model cressida intake, plenum and TB onto the new motor #3. Except I did remove the EGR system because the head on the import motor was not set up for the EGR. And as a bonus, I now don't have to worry about my EGR hitting the firewall because it was REALLY close before.

Sunday morning:
I finished assembling motor #3 and got it on the cherry picker.

Sunday Afternoon:
I got motor #3 dropped back into the 4runner. Then I started hooking back up the wiring harness and putting the assesories back onto the new motor while it was in the 4runner. Basically the less you have on the engine, the easier it is to pull and install. Pulling the engine was pretty easy because I removed the water pump. But on the reinstall I accidently already had the water pump installed and I really had to fight it to get it back into the engine bay. But I got it!

Sunday evening:
I worked on getting my 210 York mounted to the 7MGE. That really went pretty fast because I had most of the mounting brackets already made from the first time I installed the motor and mocked up the brackets. but then I got to the point where I needed a belt before I could go any farther and the auto stores where already closed. So that pretty much ended the work for the evening because I need to finalize the York before I start putting the radiator back in the vehicle. Just for the fact that the engine bay is really tight and with teh radiator out, its much easy to mock up the york brackets.

I'm hopping to have it up and running by this next weekends club fun run......
