Well guys, I just pulled all eight sparkplugs and they are all fouled beyond belief - black as can be... I'm not sure why. Several of them were only finger tight as well.

Also, I changed the oil and decided to empty the oil in the catch-can which is connected to the driver side valve cover...guess what came out? Radiator fluid. Greeeeeeaaaaaatttttt.....

Its strange. There was zero radiator fluid in the pan. The oil was not milky at all. But there is definately a leak into the motor somewhere because the catch can was full of green fluid:dontknow: headgasket?

Sounds like the plug issue is just needing to tweak the tune a bit. Plugs can and do work themselves loose. The more power you make the more the head will flex the more likely it is to have a plug get loose.

Been reading on cometics which is what I thought you said was in there. Very prone to weeping coolant. The other possiability is Intake manifold gasket or lack of headstud TQ.

That's what I was gonna say. I would retorque the head studs.

Dan,
did you use the correct ARP thread sealer for studs in the coolant passages?

Oh yeah. I forgot about that stuff. It's gray and ARP makes it.

My oil catch can gets a little bit of water too but I don't know if it's from water condensing inside the reservoir or if it's getting in the bad way...I can't really tell the color because I run straight water + water-wetter and it barely has a tint if at all.

You might be fine...I emptied some water outta mine at the beginning of the season but haven't had any issues with the car making power or going down the track at all.

Im not sure. Sean had the load cranked up on both of our cars. Important thing is the 02's are commanded for a safe a/f and thats what counts. Sean is going to help me with some track tuning.

Thats cool, I just dont see the "TRACK TUNING" lasting that long without any type of safety equipment.
 
I had a coolant leak. It was coming from the back of the engine somewhere. I checked the oil and found nothing so I just used some bars leak and it sealed whatever was leaking.

Sweet, glad to see the tracks have lightened up on their rules. I was worried I was going to have to spend more money this winter, lol.

Sean,

I'm still mystified as to how so much green water ended up in the catch can. But still, there was ZERO water in the pan. Weird, huh?

I've heard the same thing about the cometics. Only thing is I didn't have this problem at all last year and the year before with Cometics on my old combo. Anyways, I'm going to relash the Rockers this weekend and will definately double check the headstuds as far as the torque issue is concerned.

I put new plugs in it and it seems to run smoother now, but it still seems to be running a bit rich on the bottom end. I just think that the injectors might be a tad too big...:dontknow:

I want to bring the car back up to fix a few small issues that I'm having such as - line lock doesn't work and a few other items like that.

Thanks for your help.

Dan
