What gap are the plugs at? And....do a boost leak test!!

[Pushit2.0]

It sounds like the intake manifold gasket is leaking. Or atleast thats the only time I have heard that kind of noise. I would gap the plugs to 28 on you car Brian.

They are all gapped to 28. I bought a new gapper at the same time I bought the spark plugs as my old one was in rough shape.

I just bought all the parts I need to do the boost leak test but now I have to go build it. (total cost was $10) The coupler was supposed to be $8 but I convinced the lady at the self check out that there was a price discrepancy and got it for $2.79 as it said on the shelf

[SlowWhite]

just tested out the leak detector and right off the bad I have 1 big one coming from the coupler that comes off the turbo. Tonight I'll jack the car up and really go to town. So far though that was the only area I am hearing a leak.

[SlowWhite]

Well just got done fixing boost leaks. And here's how things turned out.

Leaks:
1)coupler/IC pipe off turbo, the clamp wasn't even touching the pipe anymore. Only reason it stayed in the coupler was because of how tight it was in the FMIC side.

2) Boost Controler - is leaking big time. But I've heard that was normal so I didn't do anything about it

3) BOV line that goes into the intake. - wasn't tight around the fitting. (could just slide it on and off. Only reason that was staying on was because the line is a little short, so it put pressure on the side of the valve thing. I put a smaller clamp on it and it seems to be holding now as I no longer hear any leaks.

4) TB was leaking by the intake manifold. right under the Biss screw. Some more copper spray fixed that.

5)And last but not least: My brand new 1G Magnus SMI has a pin sized hole in the #4 runner right by the head (ie: the runner closest to the passengerside)

At first I couldn't tell if it was the bolt or not as it's so little air that all I was feeling was a cold draft. I came apon while trying to see if the intake manifold gasket was leaking. tok me quite awhile to see the hole. But it's visable, I tried taking a picture of it but due to the angle it never shows up.

The hole is on the weld from the runner to the Head Plate.

Otherwise the rest of the car checks out I didn't find anything else wrong. I did switch the #1 injector with the #2 injector to see if it's the injector that's failing. But I haven't gone for a drive yet. as I've been messing with this damn laptop for the past 45minutes to get the internet working on it. As Jenny is on the computer.

all right just got back from testing out the car. And have good and bad news.

To start off ON this site I put together all the high light logs starting with warm up of the engine, Wooping up on a C5 like no tomarrow, to once again blowing the I/C pipe.

http://www.scottbarton.net/Brian/Eclipse%20Test%20Page/logs/

Just look for the logs with todays Date:

I think I figured out the spark plug issue. When the I/C pipe is connected the car runs awesome, pulled straight to 8500rpms on 1 of my test runs with 55.8lbs/min

But what I think is the I/C pipe being blown off (to hot to pull right now) the EGT's go through the roof, and the car run's really lean, on one of the logs you can see where the pipe blew off, the 02 which were holding fine, then dropped to the floor during a pull, and the logs after that you can see the car sputters, the whistling sound came back, and no top end again. I stopped doing pulls right away so that hopefully I wouldn't ruin the color of the spark plugs. I swapped them and wanted to see if it changed anything on the #2 cylinder. But I have a feeling since I was about 4 miles from home when the pipe went, I might have blotched these testing runs.

[SlowWhite]

Well the I/C pipe came loose again. (NOt completely only enough so that the clamp doesn't make a seal around the pipe... I hopefully adjusted it so it won't happen again. But if it does I'm probably going to have to try to find a longer piece of coupler I need about another 1" and that should do it.

It's raining now so I can't test the car. But if I can get it up and running with out problems, then I might head out to Moroso tonight for there night drags.

spark plugs: #2 is still black and a little wet (not drowning) so I'm thinking the coil pack is bad since I swapped the #1 and #2 injectors and the problem didn't fallow, so I think the coilpack has to be the problem.

I have to get a new valve cover gasket along with the spark plug ones. when I took the VC off to re-Torque the head studs I noticed they were all cracking. which explains the minor oil I've been getting ontop the valve cover. If the spark plug issue continues when I go to pick up the gaskets I'll probably end up buying a coil pack. Unless you guys think there is a better route I should be going?

[Matt D.]

I just read through this and I think you're on the right track. #2 is definitely missing, which means a lack of spark. Considering your lack of CEL it's probably an intermittent problem. I'd swap out the coilpack next and hope for the best.

[Shane@DBPerformance]

#2 and #3 cylinders would be the same coil. If #3 doesn't look too bad, then it might not be the coil. You could try swapping the plug wires at the coil between #2 and #3 to try to check it the #2 post is bad. #2 and #3 always fire at the same time, so it is okay to have them on backwards.

[SlowWhite]

I swapped the #1 wire with the #2 - and no change.

But I'll try running the #3 coil into the #2 spark plug, and the #2 coil to the #3 spark plug. (correct shane that's what you're telling me to try?)

Anyrate other then the spark the cars running back to what it was, so I'm about to leave in the next 15minutes to go to Moroso for there night drags. It's says "No Times" on Friday, so I called to see if that actually ment they don't give times out on Fridays and the lady said it cost's a $1 for Times... hopefully she ment for the entire night, and not "Per Run" I just want to make 1 clean pass with no problems, hopefully see some high traps or a low ET... (really I'm hoping for an 11 sec run on 92 oct, and higher then my 115.78mph previous best on pump gas)

I think I adjusted the I/C pipe so that it'll stay but I'm going to bring my leak tester incase (they have air pumps by the go-kart building so it should be far enough away from the noise that I'll be able to hear it)

Also I'm hoping they'll have the scale open so I can finally know how much my car weighs.
