Who has a smoker for exhaust leaks
I have a real bad split BLM issue. I need to check if I have any exhaust of vacuum leaks. Does anyone know of a place with a smoker that can be used to find leaks?

Just dump a little seafoam in your motor, that'll find a leak! Use at your own risk
But not sure who has a smoker or anything to check that. Check this out - http://www.camaroz28.com/forums/arch...p/t-23102.html

any sponsors do this? i don't think the neighbors would be too pleased at all the smoke i've been reaidng about. however the motor was freshly rebuilt and i doesn't even have 1K miles on it os it can't be that bad. i read the sticky about seafoaming the car. should i go through all three steps or should i just focus on one?

i would feel bad for whoever is back there the car has an ORY, !evap, !egr, and !a.i.r. a respirator would be necessary
i think i'm going with the seafoam seems like it would be the most obvious way to find a leak.

Just tighten all the clamps up and the header bolts and see if it goes away. If you have about 1000 miles on it since it was put together chances are something worked it's way loose from the heat cycles. Tightening everthing will probably fix it.
What makes you think there's a leak anyway? Noise?

if i set the car to run in open loop the O2s wont provide any correction so that is like turning them off. i have a wideband. however i dont think my wideband cable is long enough to be able to do put them in the headers. i would have to borrow somoenes lc2 or go to a shop with a dyno and have them hook their wideband up to the car. i'll have to try that if the seafoam doesn't clear this mess up.

couldn't that hurt the car though kind of similar to sticking a potato in the tail pipe lol. or are they only supposed to lightly cover the tail pipes?

i bought the seafoam. i'll be doing it to the car this week. i put it off for a little bit because i sent my injectors to get flow tested and cleaned after getting some weird header temps on two cylinders (1 & 7). i got the injectors back and they are all flow matched. once i put them back on i'll seafoam the car.

okay so i got my injectors back on the car and i took it out to log it. the left side is now in the 140-139 range at idle and the right side is pegged at 115-116. so there was an improvement the left is less lean and the right side is less rich. this is for the long term fuel trims. they are split across the board not just idle. the short terms are looking pretty good within +/-5 of 128.
im not sure if it was the injector cleaning that helped out the long term trims or if it was the change in whether as it is in the 60s now compared to the 30 and 40s. i rune in SD mode.
next step is to seafoam the car and see if i can find any leaks.

so i was able to get my hands on an hvac smoke machine. turns out i don't have any leaks at all vacuum or intake. looks like my split BLMs may be due to something else. maybe bad plug/wire or something else. all i know is that at WOT my left side is reading really lean causing the car to dump fuel into that bank and screwing up my track times. the car is supposed to be in the 11s and its running high 12s

i thought that the 02's switch off at wot. i thought that fueling was done out of the pe/ve tables at that point. i'm no tuner just what i heard. my tuner said my car was dumping fuel into the drivers bank. no matter how much he added it still wanted more. he said a leak just like your looking for. i couldn't find one though. it's still like this a year and a half later. good luck and keep us posted if you figure it out
