I can work in it easily. i built a few engines. Tbh i just don't have the ambition anymore. my opinion is that the head has dropped a valve and that is why there is such a massive amount of blow by and the rattle sound. Without a leakdown and comp test it's all hearsay. Really i only posted it up to share my pain.

Hold up buddy! Not so fast. I've got a good running '91 Supra turbo hardtop 5spd i'd be intersted in trading you for something else nice you might have. Let me know whatcha got. :evildeal:
Rebuild?? Anything can be fixed, all it takes is a massive amount of $$$$$$$$. Gotta love the 7M or go 2JZGTE.
Oh dont give up bro, rebuild, swap, whatever you feel is best and get one back on the road, then use the other as a parts car 
I know, I really like the looks of the cars. I have wanted one since I was a teenager and now I have two! Unfortunate they are both blown up. Some guys are coming to pick them up Sunday. Letting them go for 2500 for the pair. Seems like a fair price as the red car has about 3k in parts alone.
So you sold your 2006 F150 for $2500... :nono:
($1500 if you allow a grand for the other Mk3)
Life is NOT going to be kind to you...

Actually, it seems like you have an affinity for getting bent over on any deal that involves buying or selling cars.austin;1833369 said:
Seriously, you went from having a running 06 F-150 and a non-running Supra, to 2 blown up Supras, to $2500. Before: o After: O
You can guess what that is...

Holy Shit! I've never seen blow by on a 7MGTE soo bad in my life!! I would definitiely be suspecting more major damage!
This is really sad. Less that a week and 10 post you're in and out. Like mentioned earlier I really hope the seller of that Supra was not a member on here, or SF. Chances are he probably was.

If you only knew the half of it.
Ok for shits and giggles I did a dry then wet comp test.
1= 80
2= 80
3= 130
4= 130
5= 60
6= 130
there was no change when oil was added. I was really hoping for maybe just messed up lifter the car has sat for 2 years prior to me getting it. and yes it was a member from here, also the moderator for the alberta supra club.

Agreed. How much boost did you run through that CT-26? There's probably some catastrophic internal damage in that motor.
I got the car and it wouldn't idle, it had a bov and a lexus maf installed. As soon as I got it back home ( it overheated on the previous owner while he was driving it to meet me and he pulled the thermostat) I put in a thermostat, stock MAF, and removed the BOV. It was running good so I went for a drive and checked out what kind of car I had. As soon as it would rev to 4-5k the boost would fall on it's face from 10psi to 4 or 5. I drove it back to my house and the next day I swapped the turbo's. The results is this thread.
The overheating on the way was probably due to an already blown head gasket. These cars generally don't overheat - they have an amazing cooling system.
There's your problem - a Lexus AFM (it's not a MAF, it's a Karmann-Vortex air flow meter - these cars don't have a MAF) will drop the air signal by 25% which is why that upgrade is almost always paired with 550cc injectors. (Stock are 440cc so the +25% fuel flow counteracts the -25% air flow).
Running it up to 4-5K at 10psi was probably what killed it. I'll guarantee it detonated badly and destroyed the pistons and/or valves.
You traded your vehicle for one that was having problems before it even got to your house. You should have walked away right there. You were sold a ticking timebomb.
