Ran into a friend of mine at lunch who had previously quit working at the restaurant where we were eating. Asked her why she was back and the following conversation takes place:

Her "I'm having car issues"
Me "What's wrong with it?"
Her "I'm dumping oil.
Me "Uh oh. Have you checked your gaskets"
Her "Yep, sure have"
Me "Uh. I'm betting this is not good"
Her "Well we're going to replace the injectors next"
Me "Ok well that shouldn't be too bad. I'm sure you can get a full set for cheap"
Her "My injectors are $200 a piece"
Me "...what. Wait, what exactly are you driving"
Her "2006 pontiac GTO"
Me "There's no way your injectors are $200 a piece"
Her "It's supercharged'
(At this point I know where this is going)
Me "Hooboy. How much boost are you running on that motor?"
Her "I don't know"
Me "What do you mean you don't know?"
Her "I had them remove the extra gauges when I bought the car"

tl;dr there are giant scorch marks across her manifold and the car is dumping oil. Whee.
My diagnosis: Her pistons rings are toast

Any dissenting opinions?

Sometimes these forums are valuable. She asked me if gauges were necessary and I said I was told recently that AFR and Boost on a supercharged car are mandatory.

clearly gauges are superfluous anyway :rolleyes:

What kind of female drives a 2006 pontiac GTO anyway? I never knew those had a 6L V8 in them.

haha well we all start somewhere, but it's the moment you begin to flaunt it and actually have no clue what you're talking about. I refrain from calling people out too often because it's mean but sometimes it's called for!

faking the funk!

I hear what you are saying but to have gauges removed because you don't like them?? I'm an engineer so I guess I understand some of these things better than most but the point of any type of gauge is to relay information. One would think you would figure out what said gauge's information is depicting and then decide whether or not to pull the gauges based on the importance of the information. If someone felt it was important enough to install the gauges in the first part I would assume that the information was critical enough that you should probably leave them be. But that's just the engineer in me I guess.

Hit ya with the funk, its like, who cut the provolone?!?!

haha hey some older cars don't even come with tachometers haha. The car's ECU reads a bunch of things and if you really wanted you can have a buttload of gauges. Look at the guys who have like 3 running up the A-pillar, 2 by the gauge cluster, and like 9 more in the center console. On a relatively stock or stock car a boost gauge is just an add-on IMO, not necessary. Reminds me of my old MR2, the boost gauge literally just told you if you were in vacuum or in boost, no specific number or anything, sooo what's the point of that?! lol

My point was that it sounds to me like the car is running too much boost which probably led to engine failure. The gauge would be necessary to make that diagnosis prior to y'know..dumping oil all over the road.
It wasn't initially a boosted motor sooo...I'd say that the gauges would be pretty necessary.

Am I wrong here?

Also I wasn't calling her out. Were you calling me out? I don't understand. I was trying to help her troubleshoot because she has family coming over this week to help her work on the car.
I posted this here to ask for opinions, not make fun of her...?

Shoot, I want oil temp, oil pressure and trans temp on a mostly stock car just so I'm aware of what's going on with the vitals!

Those 6.0 LS motors can handle a decent amount of boost before going boom. Makes me wonder how much power it was making.

If she's running $200 (a piece) injectors...

my words added nothing to the subject, yes. No I was not calling you out. I was just saying it seemed silly to me to remove gauges.

What do you suppose this is:

My guess was some sort of mounting bracket for a tri-tip exhaust but apparently that's not correct.

I don't think superchargers can out of no where run more boost, unlike turbochargers which boost is controlled by the wastegate, there can be issues with boost creep or variations in boost levels depending on the climate

lol it's a merge collector for shorty headers

Somewhat reassuring.

Looks like Doran is going to start selling their own then. Trying to picture how that would fit and I'm not seeing it.

Its at the end of the header. It is what joins all the individual runners into one pipe that then goes to the cats/CBE

And Khoi is right. I don't see her issue being boost related at all. SC's are pretty static.

Ideas to why she might be dumping oil then?

Would I be hated for saying "because its a Pontiac?" lol because it is a Pontiac.

Just kidding :roflpuke2:
I LOVE the G8's.

But im not really sure. Not familiar with LS platforms. Not as familiar as I like to be because they are generally pretty BA.

Also just because the SC ran consistent boost, it could have been too high from the jump.

probably just a bad oil leak somewhere, her exhaust would shoot black smoke if it burnt that much oil lol

Or an oil line for the SC fell off or split? Oil cooler connection failed? Could be any number of things. Most LS motors can handle an easy 6psi or 140whp jump on a bone stock drivetrain.

That's pretty sturdy. Go figure

Nice Jay, Redline makes excellent products. Turned out great.
I have been thinking about installing a catch can too, Moroso makes a nice one for the ZL1. My concern is giving the dealer, GM rep, etc any reason to deny a warranty claim.

I think a catch can(s) are the most overlooked but important mod. Just my opinion ... but it keeps alot of nasty stuff out of there.

As far as warranty you are only messing with the vacuum lines ... but hard to tell with dealerships ... not many of them seem to dig anything aftermarket.

Yeah I definitely recognize the benefit of the catch can but I can see them possibly using that as an excuse. You would think manufacturers would see the benefit of the catch can to protect the engine and start including them as a standard part.

Anyone have leads on an R33 for sale?

o_O

:icon08:

You can always ask the dealership before you do anything. Try finding one that doesn't mind minor mods and they should be good to deal with. The guy at Sheehy Nissan in Glen Burnie told me they were cool with bolt-on mods as long as the aftermarket part wasn't directly causing a problem.

Where is this dealership at (address wise, not "In Glen Burnie, duh"), I need to get my SLU replaced under warranty, and my TPMS computer bit redone cause I've had the sensors synced about 30 times and the damn light still comes on. It must be a problem with the computer (4 new sensors are on the car).

I'd prefer to take it to a mod friendly dealer if I can... Unless there is a good one closer to Gaithersburg?

You could also try Nissan of Bowie, where we had a meet once.

I'll have to give those a look... Gotta find out if it's even possible to reprogram the TPMS system separate of a full ECU reprogram, and if that will affect my UpRev or not?

2004 GTO had the 5.7L LS1 (with many LS6 bits)
2005-2006 GTOs had the 6.0L LS2

You're right but nobody would put it in writing and then a new service manager comes in and has a different view. On top of that if it was something major you often have the regional rep come in and look at it. I picked up the extended warranty so definitely want to be careful. The catch can would more than likely be my only mod. Plenty of HP, no suspension upgrades and I love the dual mode exhaust. Definitely have some thinking to do. Will definitely have a talk with the service manager at Radley Chevrolet. Thanks Shahid.

$200 per injector is hilarious, even in a supercharged GTO. This leads me to wonder if she is even supercharged at all, and has any clue what she is talking about...

No problem. Good luck! :tup:

Yeah that didn't make any sense to me.
