Blower got installed today, but it still has a bad miss. I am assuming that when it was spitting oil all inside of the piping, it must have fouled out the plugs. I hope I can take em out and clean em and they will be fine. I can't afford to keep buying those high priced plugs. I just can't seem to win with this truck no matter what I do.

 

Crash. All pulleys were replaced while truck was in the shop, but I will check all of them tomorrow when I pull the plugs. The Riechard Racing pulley is supposed to actually extend belt life if all pulleys are lined up correctly according to the owner who makes them. I just had this thing made into a D1, so if I can't get this one from slipping without extensive mods, I can only imagine what a F1 would do. I am assuming troyer knew what he was doing when tightening the belt. BTW, I was there when it was on the dyno, and at 5000 rpms, boost dropped off like a rock. I saw 14 lbs with the P1sc, but barely over 10 with the D1. Like I said I will check everything tomorrow and let you know what I find. I didn't think those Denso plugs would foul out so fast, although I reckon the oil did em in.

 

Just got through replacing plugs in truck. Half of the plugs had the electrodes almost completely burned off of them. What could of caused this to happen? I never noticed a miss untill supercharger went bad. After seeing this, I thought for sure they were causing the bad miss. Well it wasn't the plugs, cause the miss is still there. I just can't figure what the problem is. This has me completely baffled. The check engine light should be coming on as bad as it is running shouldn't it? Right now I hate this Damn truck.

 

Start data logging and send info to Mike or head back to his shop with the extra idler pulley for more belt wrap and have him work out the problem.

 

The electrodes melting off are what I don't understand. They still have be in there somewhere don't they?

 

Compression is 8:4:1. After searching around, I think it must have been running lean somehow. Why didn't the gauge show it, or the CEL come on? Something is bad wrong, I just don't know what it is right now. Remember new plugs didn't help at all, and 5 of the old ones were trash when I took them out.

 

Motor in truck is probably screwed up because of what it did to plugs. Troyer is supposed to call me, but I guess we will see if that happens. If the motor has been screwed up because of tuning or something that the supercharger did, the **** is gonna hit the fan. If anyone had any idea of how much money I just spent on this truck, they would freak the Hell out. I am so pissed, I can hardly control myself.

 

Denso IT22 plugs were used. Not sure what they were gallery at, cause ground strap or what I call the electrodes was burnt off.

 

Did a thorough examination of truck today. I found the main cause of the miss. The drivers side injector closest to the firewall had the plug hanging half of the way off. I could not see it, and that was the problem. While I had my hand back there trying to make sure the plug wires were connected, I just happened to feel it move. Once I got it plugged back up, the miss was gone. I slowly took it up the road for a test drive, and the CEL FINALLY came on. 2 codes popped up, P0171 and P0174. Why would it wait to be fixed before the codes came up? It still has a very slight miss, but hopefully that's the older plugs I put in there to test it. I am gonna put a few miles on these, and then put new ones in there. I am afraid to hammer it yet, cause something strange still caused the other plugs to burn up. I am going to take Crashes advice and try the ngk plugs. If something is still wrong, I will gladly replace plugs to save the motor.

 

Will definately take it easy on her. Gonna keep checking those plugs daily if truck is driven that day. I am keeping Xcallibrator in truck just in case codes POP up again.

 

Please save the engine! I want to see what this thing is going to do on the dyno! Put the new plugs in her, do the additional pulley for more belt wrap around the S/C pulley, get it dyno tuned for the lean codes, and then do a MAX power pull to see your new numbers! I am dying to find out what it will lay down! Good luck!

 

Thanks guys. Nobody wants to see what she will do on the dyno without belt slip more than me. I saw where she was heading on the dyno before the belt started slipping at just 5000 rpms, and it killed me that we had to stop tuning at that point. She can turn 7000 rpms without engine damage, so I have a long way to go if we can get her setup correctly.

 

you need to get that tune fixed. the only reason the electrodes burn off is from extreme heat and detonation. run NGK TR6 plugs they are 2.35 ea from autozone i think the NGK part number is 4166. change the plugs and i would gap them small like around 28-30 it will reduce fuel burn till you get your tune figured out and keep the mixture rich.

 

I now am hearing what sounds like a tweety bird coming from somewhere. Sorry for the crazy explanation, but thats just what comes to mind when I hear it. I am gonna take it to a local shop around here Monday morning to get some things diagnosed. He is gonna pull the plugs and see what they look like. I have put 100 miles on em since putting them in, so maby he can tell what is happening to em. I will have him go ahead and put a new set in while its there.

 

I highly recommend that you get the tune fixed! running around on a engine with lean codes both banks is playing Russian roulette but with your engine! If you do have to drive it don't do any WOT runs and keep the gas tank above 1/4. When you accelerate it will slosh around and you could potentially let air slip in the pump and then you would be REALLY lean for a few seconds until the fuel enters the fuel lines again. This is what all the lightning guys are telling me for when I do my L swap. Good luck with the plugs!
