the car is smokin from the exhaust alot with no codes coming on. smells rich and smells like oil. my brother is going to do a compression test and some other stuff . im just wanting to no what else we should check for ?
i guess it can be a regulator or something he says or maybe a ring since the problem happened after i used some juice.

------------LT1-------------


dumping fuel out exhaust not normal even smoky when i get on it it will dump fuel, smell like fuel and have a light tannish color
now its even a bluish/white color????? suspect
no oil is the bumper or on the ground just fuel.

fuel psi is at 40 when at oper. temp
with vac line disconnected it stays at 40psi even ?
psi regulator isnt leaking fuel out the vac line
nor do i smell gas at that line
no leaks found anywhere from the rail/injectors
pulled out cyl # 1 and 3 no fuel on plugs at all and checked compression on those cylinders
175 at cyl 1
180 at cyl 3 with 6 cranks
havent got to testing other cylinders

UPDATE TODAY I SCANNED THE CAR.

iac motor is at 62 while cruising but at 128 koeo
fuel trim 1 % -4.7 122 idle
fuel trim 2 % 4.7 133 idle
ect 196* idle
maf (gr/s) 12.52 and volts at 2.58 while idling 4.8v koeo
tps is at .647 koeo

both front o2 sensors while cruising at 35 are between 180-900mv
both front o2 sensors are reading 800-900mv at idle completely warmed up
at idle while at stop o2's go between 62-500mv

fuel psi at 43 while cruising which is good

no codes

i was going to run some1 with the juice to seal it and make some quick cash and hope after i let off the juice the motor wouldn't blow. then i decided not to since i dont want to f*ck **** up and make it worse over a couple bucks. im hoping a bad injector or something little.

how much are you spaying? What color smoke?

Sounds like you have some blowby issues...more than likely fried the rings if it's a sudden thing like you say.

well the car doesnt feel weaker ;\ but the smoke normal looking white u can say...i sprayed it tons of time and had the car tuned for juice.

Yea, if it's white smoke I agree...sounds like you hurt a headgasket.

If the smoke is gray ish its oil. if its black its fuel if its sweat smelling and bright white water/coolant.

pulled out cyl # 1 and 3 no fuel on plugs at all and checked compression on those 2 cyl.
175 at cyl 1
180 at cyl 2 with 6 cranks

there are no codes at all.


what can this be.

That fuel pressure is low, you should be around 58 PSI.

SPEEDYTRANSAM1996

iTrader: (37)

so would that make it smoke then for being low????????

koolrayz

iTrader: (26)

It would throw your fuel trims off and make it run like ****. Fix what you know FIRST. Low fuel pressure= replace pump, filter. Your sure the regulator is good?

Jon5212

iTrader: (2)

What I'm thinking is worst case scenario... you went low on fuel pressure which means you could have went lean and toasted the rings in the motor, or hurt the head gasket as others have said and you are burning coolant now.

koolrayz

iTrader: (26)

has the coolant level changed in the overflow?
Are you low on coolant in the radiator or overflow?

when i chipped my number 7 i was burning coolant/oil.

pull out your back plugs and see what they look like, my number 7 was smashed closed.

but since you say its running fine you probably didnt smash your plug.

Just for the hell of it, pull the dipstick and see what the oil looks like. See if there are any signs of water in the oil.

thanks alot
anyone else lol
