selling or trading the avant-logs problem still exists

[1fstavant]

hey guys just figured id let you all know im selling my avant in order to move onto something more stock- if anybody is interested let me know-845 236 4380

[bassed]

You told me not to sell and now you are <sticks tongue out>. Good luck it's a tough market. I've had my 04' Jetta up for 2 weeks, it's certified and I'm letting it go for 11k and I've yet to have one person contact me. It's a 2.0L FWD, Automatic Wagon that's ideal for people trying to get good mpg etc... I'm saying this because it will take a while to make the sale I think. Talking with my dad I found out a friend of a friend is selling a 34' Parker with 1k nautical miles on it that he bought last year for 55k and is now selling for 28k<ish is effin crazy right now. Almost half price with practically no miles for one of the best fishing/diving boats made.

Look how bad resale is on Toureg's. It's f-in ridiculous. $50K+ SUV's selling for $16K and <50k miles.

Good luck on the sale.

Great time to sell, right after a rebuild.

[zerb]

terrible bardunezzzz, terrible.

at the very least, part it out....cause youll make some money back instead of slumping over and selling the car as a whole. then buy a beater pos hoopdie, and put a vr in the avant. <done>

[njm23]

this is happening because you can't figure out your problem?

[20vpower]

part it! i want some of your parts

[1fstavant]

Yea i know it terrible...yes a majority of it is because of the problem but also because im tired or dumping every last penny into this car only for something else to hapen...and i havea hooptie but no motor in it and no time to get it in not to mention the kid i bough a new motor for the passat dicked me on it and im putting back in the 280k original motor so zerb if u wanna help me get that motor in ill keep the avant its just too much at this point and it sucks not being able to go wot

[1fstavant]

got an offer to trade plus cash on their end for a 97 prelude with 50k and a guy in wisconson wants to trade his ginster yellow 98 gti 125k plu 2500 so idk i need the problem solved so i can go back to not wanting to sell this pos

[zerb]

whats the problem still here? the 12.X a/f under wot?

[1fstavant]

yes sir, thinking its a vac leak from the shitty driversport welds under full boost since it seems to run fine when im half or part or 3/4 throttle, im assuming air is being sucked through and adding air to my mixture, like i assume since with a 4bar its running just about where it should be wot, isnt that saying that its adding 10% or so more fuel to my tune and since the computer thinks its at 3bars of pressure its flowing more than it would normally, so the extra fuel is compensating for the extra air coming in right or am i just plain dumb

[njm23]

this is why I think i have chosen to get my car custom tuned locally, eliminate headaches like this when the tuner is nowhere near ur car.. Also how do you expect air to get "sucked in" under boost? Not really possible...would be getting pushed out.

not logical................

What are your long term fuel trims?

[1fstavant]

-10.8 at idle and .8 at part throttle- from what ive read dont know if its true or not but the tip is under vacuum when under load as opposed to the rest of the motor which is pressurized (since the turbo is pulling the air i guess)-my opinon, the welds have broke on the wastegate so i can see them coming apart on the tip especially with the heat and cold and rain that was occuring at the time,

but don cna you go further into detail as to why its not logical- just curious still new and trying to learn

[biketsai]

man, dont sell it, youve put too much time and effort to back out now.

[njm23]

oo, your TIP. Well def. has the possibility to bring in unmetered air if it is after the maf, assuming you run one..May be completely wrong here but I can see it starting to lean out the mixture when you start building more boost if that is the case, like you said.. and a simple pressure test would give you the answer.

[aaronamerica]

man, dont sell it, youve put too much time and effort to back out now.

thats what I was thinking, but I know what he means by spending your every dollar on the car for something else to go wrong....but hey thats the game we play if you want to go fast

[zerb]

well first, air would not be sucked through anything under boost....it'd be leaking out.
second, boost leaks make rich conditions.

[1fstavant]

but its not a boost leak its a vacuum leak and the turbos pulling air which means air wouldnt be escaping through the holes it would come in through them-boost leaks are after the turbo, vacuum is from the compressor wheel to the intake- so tomarrow im taking it off and caping off both sides and the two nipples and putting 15lbs through it to see if it will leak

thats what the guy at forieng auto in pk and arnold told me and i read it on some thing i think like vortex, so im gonna try it-and i know its not the tune because a week prior i was at 11.8 afr with a 3 bar ive checked all the grounds so unless my rail is clogged then its just a mystery and im definitly running lean so it needs to be fixed

[Toyotatech]

Anything after the turbo under boost will bleed off air causing richness, the only way to be lean under boost with a leak is if it is between the turbo and the maf or in the evap system from the intake to the n80 (the only pics I can find of under your hood it's still there) or a vac leak in the brake booster line or booster as these lines still have vacuum due to the flow by the port into the intake system. Also your maf should pull 80% of the crank rated horsepower in grams per second under a wide open throttle pull through a gear at about redline (third would be best and safest to test on).

The maf readings wont be the same depending on what MAF size he is running.

[JumboBlack1.8]

Also, just to clarify....he's not having a richness problem....it seems that he's running too lean under boost....ideally, he should be shootin for 11.5. So he's not pulling enough fuel under WOT

[Toyotatech]

I know, that is supposed to be a general rule of thumb.....but I suppose that could be based on an unmodified metering system.

Having a jacked maf would make it run lean.

[DSIguy]

John, all you have to do is call me and ask me for advice or to take a look at the car. You know i'll help you out like I do everytime you text me, call me 9 times a day about how to change oil or show up without an appt. and we still sneak you in (for hours). After all we've done I never expected to find you bad mouthing me on the web.

[zerb]

was the maf recently replaced? and youve gotta pressure test the system, that'll tell you if something is leaking. other then that, i think youve pretty much replaced everything.

[1fstavant]

so now if my evap system is leaking id be running lean i take it, only question is because i used to hear a hiss when i opend my gas tank and now i dont hear anything, seems as if its not holding pressure- but im pulling the tip off and pressurizing it to see if soapy water finds my problem

[1fstavant]

found the leak, it was one of the welds....very very tiny hole thats not even visible

[JumboBlack1.8]

How did you find the leak? I think I may have a small leak that makes my ages jump at idle, but I don't know how to isolate it

[zerb]

so get that weld fixed, reset the ecu with vag, and see what it does. little shit like that can cause tiny problems...

[1fstavant]

yea dude took off the tip and pressurized it to 30lbs and all i hear is a loud whistle sprayed some soapy water...bubles so i figure the turbo was just pulling in enough extra air at wot to lean me out

[njm23]

hopefully your car is running good after you fix that.

[1fstavant]

what i did was take a pvc cap tap it and threw a valve stem in it caped off all of the bunngs dv and n80 i guess it would be and the other side of the tip then hookd up a tire inflator and presurized it then sprayed soapy watr...ill write this better when im home and on a reg computer not a cell...but the tips at highland restoration getting re welded so well see tomarrow should have it bak running by 1pm

[Don Supreme]

Now that makes perfect sense -- A leak post maf, pre-turbo will definitely cause a lean condition.

[zerb]

Who's welding this for you bardoonz?

[1fstavant]

highland restoration...i figured hell they restore cars they beter kno how to weld....and don thats what i was talking about before lol u had me al confused

[zerb]

gabe? highland automotive? right off of 9w heading towards kingston? lol

[Toyotatech]

Glad to hear you figured it out.

I was incorrect, the check valves are in place to keep vaccum in the brake booster and line and in the evap lines, a leak in those lines would cause a rich condition also under boost and have positive pressure under boost. I was thinking because the vaccum assist for the brake booster still works under positive pressures flow by the port was still creating vaccum but I was wrong, those lines will only cause lean conditions at idle also.

[20vpower]

take a pic of the tip if you still have it out of the car

[B5A4Kevin]

if possible, can you run mafless? what do your a/f's look like then? stock dbw's can run mafless with an endtank ripped off the smic. now thats un-metered air!

[1fstavant]

yes i believe its gabe, idk its right by havspeed...whatever 60 bucks and its done, i didnt take any pics but should have, it was a very small pin hole on one of the various welds, on that tip-so tomarrow ill post some pics there probably going to re do all the welds-but if not ill have some compare contrast photos lol

and nah no dbw for me im dbc so i need that maf-but yea i think this was the problem we will see

haha i kinda feel like the coyote trying to kill the roadrunner everytme i think i solved the problem i end up having to start again from scratch
