Ive done it a 1000 times on my bike, truck, mustang, and my camaro. Never had one problem. Its not that I didnt know, just never had any problems with it until I get this car.

Just finished the compression check and heres what I got:


1- 130psi
2- 130psi
3- 130psi
4- 130psi
5- 136psi
6- 134psi

Sound about right? Car was still hot from just getting back from driving it. 142psi should be perfect so 4 of them are getting close!

I also put my NGK's back in there and now it has a miss under load. So looks like tommorow ill be swapping the NGK's back out. Always something!

Those numbers are a little low, minimum cylinder pressure is 128psi on turbo models so you are pushing it to the limit.

Unfortunatly, I was right about the rod knock. Definately from running the engine with all the coolant in it. Not saying you did it. I'm sure the retard that you bought it from drove it like that for awhile.

Glad you got it running. I knew it was either the coil packs, MAF or igniter that got soaked and took a dump.

Keep us posted!

Yep! Thats why the rebuild is starting real soon.

That and it sat filled with antifreeze and oil mixed for a long time.

Still got replace the maf. Its still got that code. Im just glad the issue is resolved, I was about to go nuts.

Alright guys I know its been awhile since Ive been back here. Ive been fighting with this stupid car for the past week with no luck. Heres my issue now: Got rid of all the SES lights except for the 52 (knock sensor) I dont know whats up with this code, Ive rewired the sensors and it still does it. Guess next Ill swap them out. The MAF is new, and all the other codes are gone. Now, it will start up fine, run fine but when the boost kicks in it will fall on its face. You literly have to let out of the gas watch the boost gauge drop then get back in the throttle to get it to move. As long as you dont go WOT or under a load its fine. But once you hit boost it nose dives. Ive checked every clamp, every pipe and I cant find any leaks. Ive checked the BPV and you cant blow through it at all. Ive backed the timing way off and all it did then was black smoke. So I know its getting the gas then. Im all out of options. I have a uncle who is a head mechanic at a local toyota dealership and was going to take him the car friday but hes in the hospital now so that puts a damper on that. Im open to any suggestions to try, Im on my last nerve with this car.


Thanks!

Ok I know this is gonna sound a bit silly but when I first got into mark 3's I did it and I have worked on cars since I was about 12. The thing was back like 1999 I didnt have internet access and I was stuck in the military in South Dakota with no reference to anything 7MGE so when doing the timing belt I got it 180 out. Sad thing is it still runs fine at idle but when you push the gas it will die real fast. Sounds funny but it will run beleive me I have seen old fords and chevy's run 180 out and they sound like crap. I am just saying this since you did the head gasket maybe check it because it shouldnt throw black smoke if you retard the throttle the computer shouldnt let it. I know you are running out of options might as well a shot in the dark it is a none interferance motor or so the toyota techs tell me so you wont bend anything. And by 180 out the cam marks were pointing down instead of up and the crank mark was pointing at them at the zero mark. But it is worth a try with what you are describing.

Thats weird but at this point Im willing to try anything. Ill see if I cant do it this afternoon.

It also makes me begin to wonder if the timing is truly right. I set the crank pulley on 0 then aligned both cam marks with the marks on the backing plate. Now the thing is, does if matter if the the crank needs to be on 0 on the up stroke or the down stroke. Or is it the same either way?

[supradaddy0803]

With the 7mge you just take the distributor cap off and when it is pointing at number one then you got it a TDC. With the turbo and not having a distributor I am not sure. Take it and align it where you got it now and try turning it one more revolution and timing it at 0 for the second time. and see what it does. may save you on a rebuild and might explain the rod knock too if the timing is off. Look in your tsrm and see what the procedure is for doing it that is my best suggestion when I bought mine for my 86.5 I was supprised at what all I was doing wrong.

almost sounds like you got a leak.

as for the cps timing,

Update. Pulled the #1 plug and turned the crank to 0. Stuck a screwdriver in there and the piston was at the bottom. Spun the crank around till the piston was at the top and lined the crank up with 0. pulled the the timing cover and the cam sprocket marks were pointed down. I removed the belt, lined them up with the marks and reinstalled. Set the idle with the CPS to 800 or so and took it for a spin. Still does the same thing. Runs good with no boost then once the boost kicks in its a dog, it goes slow. Nose dive slow, then it starts jerking. I dont understand this stupid car.
