This is gonna be long. Feedback is appreciated. Probably more of a rant than anything.

Monday: Decided to SeaFoam my car. Went to a big vacant lot. Made a big smoke show. Let the white smoke die down, then turned off and started the car a few times. Left to drive home.

On the way home, I hit a big bump and broke an exhaust bolt. My muffler/muffler pipe came loose from the midpipe and started resting against my driveshaft. I took it easy for the next five minutes until home.

Tuesday: Went to fix the exhaust, overtightened the bolts and ripped the flange off of the BBK off-road H-pipe. Ordered a new off-road H-pipe from Summit. Decided while the car was down to take off my 70mm throttle body and put the stock piece back on. Could NOT get the 70mm throttle body off! Had to pull the upper intake and beat the 70mm throttle body with a hammer to get it loose. Replaced it with the stocker. Reinstalled the upper intake and throttle body. Set my TPS to .94.

Today: Installed Summit H-pipe. Went to fire car up, it wouldn't fire. Hookedup batter charger, fired and stalled right away. Turned key with pedal to the floor, car fired, and stalled. Tried this a few more times, I could keep the car running only by keeping the gas about halfway down...and it runs VERY choppy, feels out of balance. Feels like a big vacuum leak. Lots of backfires in the intake. White smoke is coming from the tailpipes, can't tell if this is just the oil in the new H-pipe (same thing happened when I installed the BBK) or SeaFoam. Okay, must be a vacuum leak, so I pulled the upper intake again and made sure everything was connected. It was. I torgued it back down, and double checked that everything is hooked up. It is. Tried to start car, same symptoms. Decided to try bypassing the Tweecer by setting it to 5, same symptoms. Gave up, here I am.

Any ideas? I worry that perhaps all the SeaFoam didn't come out, and is causing some kind of problem.

I'm really ****ing bummed about this.

I had some similar problems with my car after i bought it. I thought i had a vacuum leak so i messed with hoses and what not then i went to fire it up and it wouldnt idle, it would die if i didnt give it gas. So i started looking around and realized that the egr gasket was hanging out and the top bolt was missing and the bottom bolt was very loose. I think the previous owner messed up the threads badly so it isnt fixed completely but i stuck it back together good enough that it runs ok. Pry try and fix it tomorrow night hopefully. So i would check and make sure the egr is tight

EGR is deleted on my car...capped off at the intake manifold and at the header.

Thanks though.

A couple of months ago I realized the torque wrench I had been using was out of spec and I'd been over torquing everything...

I probably gave it a hairline crack back then, which has been getting worse since, especially when I take it off and put it back on.

Over tightening bolts seems to be a recurring problem for me.

Man, that sux. Sorry to hear that. Hope you get her running again soon.



Lesson of the day .... DO NOT TAKE INTAKE OFF TO BEAT THROTTLE BODY OFF .... AND IF YOU HAVE TO, DON"T OVER TORQUE IT.

Well, technically...I HAD to take off the upper to get the throttle body off, and I didn't overtorque it when I put it back on (I overtorqued it months ago).

Not sure if I'm going to put the stock one back on or buy a replacement lower.

I did that too a couple years ago. this is what i learned. You dont "torque" the upper intake manifold. Only the lower. The upper you just tighten snuggly, doesnt have to be that tight.

GET OUT OF MY THREAD YOU ****IN' JINX!!

j/k

I should be able to get a new manifold on quickly...my only real fear at this point is that metal flakes got into the combustion chamber.

Cracked as in a big part is cracked right off...if you saw what the metal looks like where it's broken, you'd understand. It literally kind of flakes apart.

Overtightening is better than jimmying the threads.... . I strip anything i touch. Our poor 4wheeler had an oil plug installed at a 20 degree angle cuz of me.
