So my car has been having a little white smoke coming from the exhaust and water in the tail pipe for a while now and I only have 800 miles on the motor. It's not coolant b/c it has no smell and it can't be condensation b/c it doesn't stop unless I go on the interestate or something and it comes back. It have a slight misfire at idle and I was thinking I had moisture/water in the fuel tank b/c the car probably sat for a long time with the previous owner. And it also sat for a little while while I was building the motor. I did a compression test and I am 177-180 across the board. I have no coolant loss or mixing of any kind between oil and coolant.

The problem is that I put 16oz. of seafoam in a half full gas tank (roughly 5 gallons of fuel) so the consentration is over poweringI took it for a drive and didn't make it to far before the car stalled out on me. I put 5 more gallons of gas in the car to see if I can even the ratio out (1oz./ 1 gallon of fuel. I still can't get the car to start up. I checked the plugs and they are saturated and I think they might be fouled out now.

What are my options now? Do I need to drain the tank? I have an extra 5 gallons of gas I can add. Should I just try and syphon 5 gallons out and put fresh gas in or should I just drain the tank and drop it to inspect? Would starter fluid be a good option right now?

Like I said, fuel is reaching the combustion chamber. So I know it's not clogged up. I think the treatment to gasoline ratio is way off. Any help is appreciated. Im getting the car towed home in a few.

So today I started working on the car again so far I did the following

drained 3/4 of the gas out of the tank
changed the spark plugs
drained the fuel rail
changed the igniter with a spare
changed the cap with a spare

Still can't get the car to fire up. The car stared up every single time since I rebuilt the motor with no hesitation and now nothing. I should have enough gas : treatment ratio in the fuel tank for it to start up. Mechanical timing still looks correct.

All I did was add the seafoam to the tank and the car started right up and I let it warm up before driving it. Everything seemed fine. I went down Tchop to the chevron and turned around and it started missing and then it eventually stalled out so I pulled over and got it towed home. So I assume it's the fuel treatment but after draining about 8 gallons of it out and putting 5 gallons of clean gas in I can't see it being the seafoam. Im not sure what to check now.

Just went out and tried to mess with it again. I had to use jumper cables in order to keep cranking the car over to see what I could find. It seems like the car wants to start up but won't. I pulled the plugs again to take a look and I found that the new plugs are as followed.

cylinders 1 and 4 are clean and smell like fuel
cylinders 2 and 3 are black and a little wet

I wasn't getting this result until today.

I can hear 2 pops coming out of the exhaust but wont fire up. I checked to make sure I was getting spark to all plugs by removing the plug and attaching it to the wire and resting on the valve cover while turning over. I could see fuel being pushed out of the cylinder as I turned it over. Could the poping be valve related? Tomorrow I am going to do another compression test.

I have 63 views and no suggestions. Any ideas and theories are welcome at this point lol.
