Re: Emissions retest another failure
i think ryan is right about the pvc system in connection with the plugs .daryll do you have a couple of leaking spark plug tubes ,leaking oil , i had this on my white car and found that when i used the tapered plugs those plugs in the leaking cylinders were darker .they also seemed to, not be tight when i went back and cked them . i went to the standard gasketed plug and this stopped some what. till i just bit the bullet and fixed the problem . my thoughts were that oil got into the combustion chamber everytime i pulled the plugs making them darker . now with the problem fixed they all look the same .hope this in some small way helps .

1st test $36.00 2nd re-test Free 3rd test $36.00 My advise to anyone else considering long tubes is to stay away from the metal substrate bullet cats and go with the bullet ceramic cats. I think they are too free flowing and will never meet a 1.00 HC standard. My factory cats when not damaged would pass without a problem. GC

Nick, right behind the collectors, I know heat was not an issue this time as the car was about at 80% band about 230. I held the car at 2000 RPMs with the AC on like FU said. I could see the heat thermals in the shadow my car was casting on the ground. Every states different I just dont think they can meet the 1.00 HC standard or the 2.5 NOX standard. Its possible its just too much motor for the cats. If I was to do it again I would go the ceramic route. I would not reccomend these to anyone, Jeffvette swears these are 100% identical to the RTs but who really knows. Its a non issue now. But I am leaving the cats in place as its the right thing to do. Thanks for all the ideas folks, at least you know these did not work for me so buy accordingly. Side note: The DRM Proms is back in and the car is happy so I am happy. I have never seen a car POWER through two exceedlingly fouled plugs and 2 suspect plugs that were loose. Its a testiment to the engine. This car is a beast that likes to be beat on. Try this with the girly cars. This is why I believe when its tuned right, it will run very very well.

Re: Emissions retest another failure
Has anyone ever tried or thought to try tying in to the PCV lines with an external electric vacuum pump? could tie in to help out the PCV system or eliminate the PCV set-up all together & just run the vacuum pump directly to the engine, would be a closed system. i'm talking about, rig it up for the test, PASS, then take it off again. i dropped off an engine at the dyno i use this evening & i took an electric vacuum pump i own to use on this enigne. not sure what the customer wants to do for sure regarding elec. or mech. vac. pump, so for now i'll just use the one i have around strickly for dynoing & he can make up his mind later. when i was dropping everything off i started thinking about this problem being discussed on here the last couple days. as i've stated, emission stuff is not my deal at all, but i use vacuum pumps, electric & mechanical, on 70% of the engines i do. it makes more power when done right, proper rings, ring lands cut accordingly etc., but it also helps clean things up a lot. i've never been a fan of the PCV deal, i understand why they did, just don't like it...

Re: Emissions retest another failure
GC, here are my results from January of 2008 (last time the car was tested). Car has:
Jeal headers RT metallic substrate cats Haibeck chip Stock injectors (at that time)  The numbers don't seem to correspond to those you are posting, unless you remove the decimals from your numbers (or add them to mine). I do not think the metallic substrate cats are the problem with your car. Best of luck! Last edited by Nick; 03-12-2009 at 12:34 PM. Reason: spelling error |
