Just got off the phone with the wrecking yard. Sounds like I have two main options.

A) They exchange my motor for another junkyard motor from a symiliar make and model of donor car. I'm not sure about the warrantee on this but I think I would just rebuilt the complete motor becasue its probably going to be high miles.

B) They give me a Jap import motor with a 9 month warrantee or 9,000 miles guarenteed to have 30-40K miles. And I remove all my asseccories, intake, exhaust, sensors, etc. from my 89 cressida motor and install then on the Jap motor. Then I return the Jap motor asseccories and the head and block from my motor back to the wrecking yard. doing this I would have to pay for all the gaskets required.

So I took option B basically because I will have an extended warranty. This will also get me back on the road in the least amount of time with the least about of funds. Then if this one goes (knock on wood), I would probably just rebuilt it. So by the end of this week I should have a Jap motor from a 89 Supra that I will have to start working on.....

Well I picked up the Jap import motor today. So onto the pictures...

Got to love that flesh colored duct tape!

So to me it looks like the motor fell in the ocean on the way over.... I just can't believe how much oxidation there is on it.

Here's the best part - instead of draing the oil thru the DRAIN plug they drilled a hole in the oil pan and then stuffed some cotton type fiber in it!

Well looking down the intake, it looks pretty clean in there!! No carbon oil soot buildup like my previous motor.....

Plus the recess in the head between the valve covers is not filled with chocolate pudding crap like my previous motor!

and looking down the down the oil fill cap, it also looks pretty clean inside.

Well thats all the pictures for now..... Hopefully the outside appearance doesn't refect the inside of the motor!

I forgot to mention that I pulled the Y- tube after the TB off the plenum and that 6 bolt retangular plate off the top of the plenum and it looks really clean inside. There is no oil carbon sludge buildup in the plenum that is typical of these motors. Its kinda odd looking inside with a center butterfly thingy inbetween the #3 & #4 intake runner which is also right next to the cold start injector. I also pulled the valve covers and there is very little build up in there. the cams look like they have very little wear on them also, better then my current ones. I also pulled the plugs and they all look a nice shade of coco brown with no carbon or oil on them. the plugs where pretty loose and the inside of the intake spells like fuel, so I'm guessing they compression tested the motor before they pulled it from original car. I also looked down in the cylinders through the spark plug holes and the tops of the pistons do have some carbon build up on them but they all look pretty much all the same. So this motor does appear NOT to have any major wrong with it so far, unlike the first one I got with its blown head gasket!

Well I tore into the import motor some more today.... found a very funny looking puddle of black sludge in the #5 efi runner....

And then I found this in crap in the water pump...... I hope this is just someone setting this inlet end in the mud or something because if I find this crap in the block, I'm taking it back..... As it is, I'm going to ask the wrecking yard about it! Its odd because the inlet has got this mud crap in there but the outlet of the water pump looks like its got gear oil or something in it.....VERY STRANGE

All the intake valves got lots of crap sitting on them so I'm now almost positive I'm going to pull the head and go have a valve job done if the issue above is not a problem

And the exhaust ports look okay.... but the soot that is in the ports feels gritting and not powdering like exhaust carbon would feel like. yet another reason to just pull the head so it can be hot tanked.

Here a picture of the intake valve train. and no I didn't clean the inside of the valve cover - it looked like that when I pulled it off!

And a picture of the exhaust side valve train....

And this is pretty much how it sits right now until I can talk to the wrecking yard about the mud in the water pump!

the inside looks so clean b/c the importers thoroughly clean them before delivery, i watched them do it to my motor. They look alot different when they come off the pallete compared to what they drop on your doorstep. The JDM motor i got also had that mud looking sludge buildiup in the cooling system. After one flush and some scrubbing it was all gone. No idea what its from. Could be when they wash the system all the buildup inside the cooling passages collects into the water pump assembly.

Well the Wrecking Yard gave me the OK for pulling the head to see what else I find. (I didn't want to void the warranty.) The head looks to be in pretty good condition except #1 cylinder is different in appearance.

Picture is HighRes - so please click on this link.....

And here is what the block looks like! UGH...

Picture is HighRes - so please click on this link.....

All the exhaust side water jackets are really deformed and were probably leaking or would have leaked in the very near future.

#1 cylinder metal comression ring has a small gap in it and two badly deformed sections. I would consider this a blown headgasket! So that makes two engines now with a BHG!!!! #6 also is starting to deform and is kinda egg shaped.

On top of most of the pistons is this weird red fluid. kinda looks like red anti freeze but has a flameable smell to it like its some type of cleaner solution or something.

Also on top of most of the pistons and the sides of the cylinder walls is this loose hard debris stuff. Could just be carbon build up but I never seen carbon on the walls before. and just turning the engine of by hand seems like this crap would get stuck in the rings to me and start scaring the cylinder walls.

There is also green corrosion on the water ports on the intake side of the block. looking down in the water ports in the block I can also see lots more of that dark brown muddy crap inside the block!

To me this looks like a Core motor that should only be used for a rebuild and no way would it last 12 months or 12,000 miles!

So anyways, I'm not happy with the condition of this motor at all! I'm going to try to get another one from the wrecking yard. I really don't think I'm asking for too much.... Just a motor that is in good working order with a warrantee! And hopefully a motor that can last through the warrantee and more....

Just got off the phone with the wrecking yard. They are getting me another import motor. So what I have to do is quickly bolt this one back together so its not in a pile of parts, so they can ship it back to their importer so they can get their money back. So as of right now, its looks like Friday or Monday I get drive back to the wrecking yard to trade this junk import motor for another import motor. Lets hope Motor #3 is in good working condition!!!

Tonight I spent about 1 hours putting the motor back together. I was surprised that it didn't take longer.

I also received in the mail today my full gasket rebuild kit from www.gasketpro.com for $132. looks to be in good condition and has silicon valve cover gaskets, a fel-pro graphite head gasket and several viton seals....

Rick, sorry man, I havn't been following your thread lately. New baby and all. Really havn't been able to spend much time on the forums.

Anyway, sorry to hear about your misfurtune. Bearings are pretty common on junkyard motors. Most have blown HG's and with that comes rod bearings. Personally, I would get a new set of bearings from the dealer, just the rod bearings. I have never seen a 7M with bad main bearings.

Also, about your oil pump. What was your oil pressure at idle? If it is low, you really need to get that pressure up. I did this by modifying the oil pump housing a little...more of just reconditioning it with several different grits of wet/dry sand paper and a corian cutting board(smooth surface). If at all possible, it is always a good idea to add depth to the oil pan and lower the oil pickup. The 7M seems to be a little higher off the bottom than many other engines.

I wouldn't recommend using that oil pan gasket you got in your kit. Just use FIPG, and really goop it on. I have to repair the oil pan everytime I remove it after I use FIPG...stuff is tuff and won't leak.

Whatever engine you get, REPLACE THE HG, if you don't you will later.

On your temp guage, are you watching a stock or aftermarket temp guage? I noticed the stock guage is much slower to respond than aftermarket guages.

Not really sure what to say about your poor gas mileage and poor low end power. With a turbo, I had no problem running low RPMS, so with a non-turbo, you should even be better. You sure you didn't have any vac leaks? I wonder by running shorter intake plumbing if that could cause problems? Make sure your O2 sensor is working properly and that you have your speed sensor hooked up. Those two things will really affect your MPG.

Good luck with the new motor. You thinking about keeping it and maybe just get the crank reground and put some cleavites in it? Total cost would be about $200 depending on local shop prices.

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.....

Good luck with this one. Remember the oil pump mod.
