I finally fixed an electrical problem I had with my CAS yesterday, so it was my goal today to get the motor to start. I already setup all of the timing stuff to the Hitman's specs, so I was ready to give it a go.
For those of you who don't know about my setup: 13b Cosmo, T04R turbo, Haltech E6X, custom exhaust manifold/downpipe, Tial 44m V-band WG, NGK plugs, TII coils, NGK plug wires.
I tweaked the trigger angle just a few degrees as the engine didn't want to start at the initial settings. I settled with a trigger angle of 63 and at 50% throttle she would stay alive for a few seconds (I have no idle speed motor). I should say that I'm running one of the Hitman's maps for a T04 turbo with 1680 secondaries. I tried multiple times at different throttle positions to get it to run for more than a few seconds but unsuccessfully.
I let my dad try his luck out while I took a look at stuff in the engine bay to make sure I didn't have any leaks. The first thing I noticed was the leak between my manifold and the motor, which can hopefully be fixed easily with a gasket, but I also noticed a bunch of oil accumulating under my wastegate. After taking several minutes to determine if it was the oil pan that was leaking or the motor itself, I believe the oil is coming out of my exhaust ports, into the manifold, and then out of the wastegate and downpipe.
There were a couple times that the engine did experience fuel and oxygen combusting without the aid of ignition. My question is, are my oil seals blown? Could something as simple as attempting to start the motor with less than perfect timing cause something like this to happen? Or did I have a bum motor to begin with?
I am not an expert on anything here, so if you read this and think "this guy is a ******* moron" please educate me in a constructive manner.
Here are the gruesome pics:

Help? 
I guess I could take the turbo off and check for oil in the turbine...that might narrow it down to the turbo getting too much pressure...
It's really not smoking, or that I can tell (it's in a garage), but the oil is dripping out of the DP.

[quote name='j9fd3s' date='Jun 28 2005, 09:28 AM']i would get it running better, and run it more. it could just be junk leftover from trying to get it running.
so you've zeroed the timing?

Yes the timing has been zeroed.
If I was at home I'd check the vents by the oil neck...I'm told they exist anyway...LOL.
It's just weird that it's dripping, which makes me hope that it's not the oil seals.
As far as the exhaust leak between the manifold and the motor, can a gasket be purchased to fit there? Or do I really need to mill the manifold flange?

theres supposed to be a gasket between the engine and manifold. use a t2 one

****, Mazdatrix's gasket is $69! Seriously...I'm gonna keep searching.
As far as the ventilation issue, is this adjustable or something?

yeah you basically wanna set it up like the factory had it, or make sure you have a slight vacuum on the crankcase

Hopefully it will make sense when I can look at my motor again. I'm praying that's my problem.

get the haltech running better and then worry about it.
