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?

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.
