well, after having my thorleys for 3 weeks, waitin 1 of em to get put in, i am way pissed off after install! there is a exhaust leak that makes my truck sound like a redneck 1970's pill o' sh!t rust bucket.

 

i can't even tell if there is a performance gain b/c the sound of my engine blows!

 

on top of that, the SES light came on! WTF

 

You guys have any tips for me now??? im $800 into this d**n thing and i want it running right!

 

the leak seems to be comin from the y-pipe ish area. or near the cats somewhere. i couldn't look tonight cuz its cold and dark.

 

also, it kinda smells like something is burning, but i looked all over, nothin looks burnt.

 

WHAT DO I DO!!!!!!!!!!

Thanks, Aj

Aj, new headers always give a burning smell for the first week or so, depending on what they were coated with. The painted ones are worse, and the HPC are the best.

Leaks are tough to find sometimes. You can't go sticking your hand around the pipes to feel for the leak. A trick i've used is to tape a flimsy piece of cloth on the end of a long screwdriver with about 2" hanging off the end. You can pass the cloth over all the joints and watch for it to flutter from the leak. Hopefully it's at one of the slip joints and not at one of the welded pipe joints! The first place to check is the gasket where it bolts to the head, the second is the flange where the Y pipe bolts to the header.

 

Good luck, hope they don't have to come off to fix the problem!

I feel your pain. I deal w/ this a lot. Im assumeing that you went back and re torqued the bolts? I would also upgrade to a good gasket if you did'nt. I would look in to some Fel-Pro or Flat Out makes a good Copper gaskett. just a thought.

yea, im going to go back to the shop and have them fix it! im pretty sure the leak is at the collector, not in the engine bay! the burning smell is definetly the headers gettin "burnt in"... no wires are touchin soo thats all good. and from what others have told me the SES light is on b/c of the leak...

 

all in all, performance seems better, i still can't drive it hard b/c its snowing here, soo we'll find out soon... i'll post up whats happening soon.

thanks for all the comments guys!

I bet you put the gasket on backwards. I did that on a header install once and it made the exact same sound and i was like wtf?? but i flipped it around and problem solved

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.

      OCI, not when but why?

      By Chuck FB · Posted

      The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".
