Coolant in exhaust? what makes you think this?
As for the missing of the cylinder, did you replace the spark plugs & spark plug wires?.
You need to be more specific. Is the coolant inside the exhaust? or is it on the outside?
No turbo seals will not do that. If you're burning coolant or have any coolant coming from the exhaust its most likely a bug due to improper rebuild.
Sorry, it has brand new ngk spark plugs, wires are good. I also tried pulling the fuel infector plugs to see which cylinder is dead. 4,5, and 6 all caused the engine to bog down more. 1,2, and 3 did not affect the way it is running, in other words it did not cause the engine to bog down. Also i the wall of my garage behind the exhaust is getting splattered with coolant.
Something wrong happened during rebuild, or you got a bad gasket.. sounds like 1, 2, 3 are dead or dying... that's where you're coolant is coming from I bet...
Compression test may tell you better than we can

Read what Im typing. If you did the rebuild in a home garage, unless you have proper engine shop & lathe tooling, you didn't do it correctly. The bhg never really Bhg'd, it just re-bhg'd.
Pull each of the plug wires from 1, 2 & 3 at the coil pack while running and see if you're getting spark. Do it with a pair of pliers so you don't get zapped doing so.
Any visible coolant seeping outside the block?
Did you have the block decked, and if so did you do it with timing cover plate on at the same time? If you didn't your head will not seat properly and coolant can be leaking into the first three cylinders? Look at your plugs.
Go to autozone and rent one of these. http://www.autozone.com/autozone/ac.../_/N-263r?counter=0&itemIdentifier=84330_0_0_
Easy to use, and see where the coolant is coming out of. Put #1 cylinder to TDC, take the plug out and see if it is filling up. Also monitor your oil for any milkshake. Check your coolant of any mixing of oil too.

My supra rolled in my garage with a rod knock & bhg & rolled out running with a "Not BHG." lol & now has about 3500 miles in 5 months & no problemos yet.
Yes the block was decked with timing cover on. It should seal good since I did not use a metal head gasket. I am going to test the compression in all the cylinders when I get a chance this week. Also so far there does not appear to be any coolant in the oil or oil in the coolant yet. And I am getting spark on every cylinder
What was the cause for the engine rebuild? Overheated & BHG? Rod knock? High milage with very low compression?
Is it possible you have a cracked head? Just grabbing at straws here. How did your compression, or cooling system pressure test go?
Well yesterday I swapped out the injectors with different oem ones. After putting it all back together I checked for codes before starting it. It is throwing one code, 51. Which after some searching, it deals with the tps. I checked and I did have it hooked up correctly. I tried resetting the ecu but after every attempt, it still shows the code. Any ideas? The tps is less than a year old.
if you said u changed the head gasket, maybe you have the wrong vacuum set up wrong, mixed with the coolant and air vacuum

Have you set the TPS properly? Make sure the climate control is off, and that the accelerator is returning all the way to the closed position as well.
Ok, now we're really confused.
So, those should be functioning correctly.cfurlan;1694541 said:
So, why are you pulling the plugs from the cylinders that are working? You need to check 1, 2, and 3 according to your earlier post.cfurlan;1696686 said:
Maybe its just me.
Are you sure coolant is coming out the exhaust?
Youll have condensation in exhaust and it will blow out. And youll notice it since your exhaust up against the wall.
One thing Ive learned from troubleshooting. Check the obvious first.
Since motor was disassembled, go back and make sure plug wires are seated both ends and in right location, make sure inj plugs are in correct order, you get the idea.
Double and triple check.
Eliminate the obvious first.
If you have a plug soaked in gas, its probably not firing. Plug wires, coils and coil wiring check. Make sure your coil wiring harness isnt fubar. They are usually brittle and bare wires showing. And if you dont have factory plug wires, make sure they "snap" on a plug. Use a spare plug to tell.
Just my two cents
