We'll got it all put back together ntk? 02 sensor installed cause it's was missing and was getting heavy fuel also from a vacuum leak I had all fixed now but now I'm getting heavy white smoke on acceleration never did it before so don't know it it's heavy fuel again or if I messed up the intake gaskets on install it was a tight fit also if any of my injectors were bad I got newer injectors on the way along with a 50 mm throttle body also I managed to dig up my msd 6al box I bought 5 years ago and never used along with a blaster ss coil but before that install I wanna get my distributer replaced it snapped the screw hole completly off after I taped it so it's zip tied down again lol

Ok here's what I found out I did a coolant pressure test again and cold don't lose pressure from what iv seen but when I did the running test I couldn't get a raise in the coolant so I got curious and put pressure I the system and it lowered a hair so I checked the exhaust and it smelt a bit sweet and I was getting sprayed in the face with wetness spatter I don't believe I have bad heads I didn't have this problem before do you think I could of put the intake bad I did have a problem with the back thicker gasket on the intake manifold kept falling off or moving and maybe in moving it back off and on I could of messed up the side metal gaskets I hope that's it :/ thanks in advanced to hey you you've been a lot of help hope I can get a bit more

Need the gauge set to do leak down test. Probably can rent one from any major parts store....
Basically, leakdown test tells you how well the cylinder seals, and where the leaks are. Screw the gauge in, apply air pressure, read the gauges. (I use 100PSI input pressure, to make the math easy.) If you get 80 PSI on a cylinder, then you have 20% leakdown. If you listen carefully, you can even hear where the air is escaping.
According to the manuals, up to 25% leakdown is 'acceptable'..... (which seems excessive to me.....) and all cylinders should be fairly close. (within 5 points or so) Lets ya know where your problem areas are. Best done on a fully warmed engine. (and test cylinders while they are in firing position, just like compression test.)
