So, finally after about 3 months of waiting, I finished my head gasket, 60k maintenance, and Timing Belt job (All new OEM timing components).
*Also did a vacuum delete (kept ALL solenoids plugged in* and kept FPS vacuum line) [Re-routed my Boost Gauge Vacuum to the "P" port on the Throttle Body, and capped the end on the old vacuum "T" that I put on the FPR Vacuum line] installed a NXS Motorsports MBC, replaced the OEM radiator w/ the CX Racing one, and upgraded my Fisher Price 2g BOV to the 1g :)*

It was my first major tear down, as I am 21, and just started working on the GSX when I got it back in May. It took a bit longer then I had hoped, but I learned an invaluable about of information about my car, and when things finally "hit" me so to speak, progress went by A LOT faster.

(Here's my "big award speech" LOL- Thanks everyone that helped me with the questions I had in my related threads (http://www.dsmtuners.com/forums/newbie-forum/442349-vacuum-delete-clarification.html , http://www.dsmtuners.com/forums/new...60k-maintenance-how-does-everything-look.html , http://www.dsmtuners.com/forums/new...-balance-shaft-belt-sorry-another-thread.html) Without you guys I would have probably still be working on it, and REALLY, REALLY, REALLY PARANOID I was doing something wrong. Also another BIG thanks to just DSM Tuners in general.)

When I first started it up everything seemed fine, well minus a slightly high idle. I adjusted it, and was able to get it down to 800-900 ish range.

While it was idling I was checking pretty much EVERYTHING in the bay, and under as well. I didn't see any leaks, and when I felt comfortable, I took it for a short drive around the block.

I pretty much babied it during the whole trip. Boost hit about 12 psi as a high, but was mostly around the 5-8 range. It sounded if the crushed 1g bov I put on was "fluttering" at low boost. When I hit 10-12 psi, it sounded normal -at least to me. Anyways, both the stock, and my aftermarket Afterglow Digital Oil Press/Boost gauges checked out fine during the 5-10 minute trip.

I did have some smoke coming from the bay when I parked it, and let it idle after the trip. I pulled the header heatshield off, and noticed that the new engine spray paint was completely burned off my header :( and I had to retorque the nuts/studs of the header. I attributed the smoke to the Seafoam, and engine spray paint. It has since been fine.

After I turned it off, I found a huge puddle of coolant under the ground. I finally sourced that, and fixed that as well. I also had an oil drip leak coming from the bottom of the lower timing cover where it sits against the oil pan. <Installed a whole new timing cover gasket - lower, middle, upper>

It's a pretty decent leak, but it's not major. I was able to drive it about 30 miles round trip without any troubles, but I am finding myself constantly having to check the oil levels, and add some almost every trip.

I have changed the oil/filter 3 times this week just to get make sure there isn't any of the shavings still floating around (Did Bogus' method of sanding the block -but didnt block any ports on the head/block)

But anyways, I took the car to the shop, and the leak was narrowed down to the Timing Cover, and not the Oil Pan gasket itself. I wish I took a video of it, but didn't. So, I will try my best to describe it.

-Also the mechanic had asked me if I had greased the ending of the timing cover gasket/seal that connects to the block, and told him no. He said that was most likely the cause of my leak, but he also said that he is mostly a muscle car guy, and not an import specialist. -Really knowledgeable guy though-

It seems like the leak is coming from the red square that I put in picture 4. If you were to look up the little passage way it seems to connect to the very bottom of the furthest left part of the lower timing cover -atleast to me this appears to wear it connects to. I put up some more pictures as well.

When I took the lower timing cover off yesterday after coming back from the Shootout, I noticed that the new gasket still looked fine, but almost all the new timing components had a thin layer of oil all over them. Does any of these bolts have an oil galley? I am not sure where to go from here, so I need your guys advice. I was thinking maybe I didnt torque something down tight enough if it passes through a galley, or I didn't tighten the timing cover tight enough.

*The red box on the timing belt cover is where the crack is located, but oil doesn't seem to be coming from that area.*
-Also what seems to be going on w/ my Balance Shaft Belt? Is this normal?

Hopefully you guys can help out. If you need anymore pictures, or information just let me know.

Well you gotta know that the timing cover is there to protect the timing belt from dust, water etc. Not to prevent oil coming out from timing belt housing. So, having oil in there is not normal. I don't know why would that guy tell you that not putting grease in there is the reason. I wouldn't trust him again.

To me your oil leak is caused from the seals (crankshaft's or balancer shaft's) or front case cover gasket. Can't really see it good on your pictures.
What you can do is try to clean the oil in there, then take a spin and after that try to locate where the oil is coming from. That would be your leaking seal.

@drive-maniac- I didn't think oil should be in there. I thought maybe a bolt passed through an oil galley, and it wasn't torque correctly causing the oil to come out.

If that wasn't the case, I was going to look into replacing the seals. I have to find a good write-up on here as I am still learning about the engine, and how-to's.

Like you said, I was thinking of putting the accessory belts on, and starting it w/ out the Lower Timing Cover to see if I can pin point it. I just wasn't sure if that was ideal, or not.

Thanks for the advice, much appreciated!
 
For some reason I didn't even think to use any... shiiiiiiiiiiiiiit. Well atleast I know the problem, and will redo it this weekend. Thanks for the advice though!

I seem to be having this same problem... except mine is on a 90 talon....
By auto tensikner bolts do you mean the ones for the timing belt or does the 2g use a serpentine?
 
Turbo Virgin - I was referring to the two bolts thay hold the Auto Tensioner to the block itself (Picture #7 *left side*) All I know is that part various between mine, and yours, and that's all. Hopefully someone more experienced can chime in.
 
Those two timing tensioner bolts shouldnt be your problem, as they dont block any port or come into contacy with oil. Your problem is a seal that blocks off oil seepage

Oh ya dont use that mechanic again
