Misfire problem solved: MACE intake manifold FAILURE - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

DarkneSS · 06-09-2013, 10:10 AM

So I've been complaining about a misfire for I think weeks now. I tried a lot of different things to fix it but none worked so I had to take my car back to the dealer. They reprogrammed my car and said I was good to go. It stopped misfiring after I took my mods off (vararam, elite catch can, mace stage 3 intake manifold + 25mm spacer), but I thought the mods were exacerbating a larger problem. Tracy from RX and I didn't see how the mods could have caused the misfires. The car ran fine for 400 miles too with th mods on.

So for those who don't know, MACE fills in this portion here on the bottom of the manifold right after the throttle body to allow better airflow.

You'll notice you can see the hole, well, thats because the filling they put in there became DISLODGED and was nearly SUCKED INTO my engine!!!!!!!

:confuse d0068:

IF YOU HAVE A MACE PORTED INTAKE MANIFOLD, I HIGHLY SUGGEST YOU REINFORCE THIS PIECE WITH SOME REALLY STRONG GLUE!

I'm extremely lucky that damn thing didn't break into pieces because that would have been the end of my engine, NO warranty coverage at all.

Fortunately I caught this. This manifold is sold but it is now very safe. I put a mass amount of strong glue and sealant so it won't get break off again.

I'm just incredibly thankful nothing serious happened...

Damn that's crazy! That's the first time I've heard of something like that happening. I know both RX and MACE fill in that portion. Good thing you caught it when you did!

LIM3 · 06-09-2013, 10:17 AM

That's crazy man. Glad you caught it in time beiges it completely destroyed your engine.
What are your plans now that the problem was fixed ?

GretchenGotGrowl · 06-09-2013, 10:18 AM

I'm in a great position now, I've got 14k and an engine that obviously is perfectly fine. I have a great deal on a SS lined up that will probably go through. If for some reason it doesn't I think I might go FI.

Holy crap! I need to check mine haha.

I think with the left over money you have from going FI you should give it to me jay kay

. Glad you figured out the problem!

V6owner · 06-09-2013, 10:37 AM

That's crazy

BaylorCamaro · 06-09-2013, 10:59 AM

Wow that sucks, glad I had mine ported and polished from a different company that didn't do that filler.

Ventmaster · 06-09-2013, 11:14 AM

Whoa! I had worried about the possibility of this with repeated heat cycles, etc... No matter what kind of adhesive used, I think you'd have to weld it in place (not just JB Weld). Which is what I thought Mace (Bmore) was using.

How long you had that IM and how many miles on it?

MACE_ENG · 06-09-2013, 11:40 AM

WOW! I'm shocked myself. This is the first we seen this happen out of hundreds we sold! I personally apologize that you had to experience this op. We try to make sure every IM that goes out is checked for trouble free operation but I guess there's always going to be at least one bad Apple out the bunch. The material we use is heat resistant capable to withstand everyday operation of your vehicle. Heat wasn't the issue I can assure you, and especially if you are also running a insulator. The problem was probably prepping before the material went on.

If for any reason anyone would like us to check this area and redo for assurance please drop me an email directly to velocityport410@gmail.com and we will sort this out for you

but please understand that this is the FIRST we heard of this. We have guys that put on thousands and thousands of miles with zero issues.

Again, I truly apologize this had to happen op.

Mine's been on for over 25000 miles so I have to agree that I don't think heat is the problem

KMPrenger · 06-09-2013, 11:56 AM

Holy cow! Thank goodness it held together!

Yeah I bet your car is running better now for sure.
