[DML] Troubles-updated/flames from exhaust



Yea?flames?but I'll get to that later-I'll start by
mentioning the 
work I did. I removing the intake to find that the #4 O-ring was 
leaking (oily substance dripping down from the ring), so I cleaned 
all grooves with a Q-tip and rotor cleaner and smeared a light coat 
of hi-temp silicone over the rings. I also did a vacuum test, 
plugging in my gauge left side intake barb. My gauge jumped madly 
between 16~17 and 19 in HG, and stayed like this even while revving 
up, increased over 20 when I let off the throttle-which is normal. 
But is the vacuum reading at idle something I should be concerned 
about or is this good? Leaving the vacuum lines hooked up or 
stopping them did not impact the reading. Also while dealing with 
the intake rings- I cleaned the contacts of all sensors in the water 
pipe and put it all back together again. Playing with the FV today-
Just for kicks I took out the jumper wire I installed in the full 
throttle switch and after adjusting the CO once again, Bingo-the FV 
runs constant! I still have a warm-up and hard start problem though, 
but I know the starting is from a leak in the system somewhere 
because every time I go to start the car, even a half an hour after 
shutting it down; the accumulator needs to fill. I can tell because 
I can hear the spring in the accumulator kinking under compression. 
There is a strong odor of fuel outside the car and sometimes inside, 
so I'd doubt my accumulator decided to quit; its only 4 years old
at 
best. Odor is coming from??? Not sure, not from the engine bay and 
the trunk always has light smell of gas but I checked the pump and 
the boot isn't leaking. This leaves the lines and everything
under 
the car. I'm going through gas quicker then normal so leak is my 
guess. Now for the flames thing, I was still tinkering with the car 
in the dark and figured while I had the car running I'd try the 
flashlight to see exhaust smoke like others recommended. Well I did 
this both at idle and while revving the car and noticed a 
whitish/bluish puff of smoke when I hit the spool to rev the car and 
sharply let off. I shut the light off and turns out this wasn't 
smoke at all, but flames! When I sharply rev and let off, the 
muffler cracks while blowing small flames from both pipes. I have no 
catalytics installed yet. I also have a loud knocking valve on the 
left [4-6] bank I'm investigating. Could this be from bad valve 
timing? I checked all valve lash on this bank and they're all
fine? 
If anyone has any suggestions or comments on any of this, I'd 
appreciate it. Thank you all for your help and KEEP YOUR DELO DRY 
down south! Hope everyone affected is okay and stays safe! -----Dani
