Oil leaks - Mystery

[Pimpin Dsmstyle]

91 talon TSI awd turbo.
Stock rebuilt motor
BS removed

We used the wrong RTV on the oil pan the first time around ( recently changed back to the correct shit, black RTV, oil resistant).

The Timing belt is being "soaked" by oil. At first we thought it was the oil pan because we had the wrong RTV on it but we fixed that, let it cure, put in oil.. ran it and blah, leaks probably more than before.

We built this along time ago. We might have used RTV somewhere else that is causing this problem. The oil is all over on the front case side of the motor.

My question is, where have people have this issue come from? I know Nash had some sort of leak from the front case, maybe it's a similar issue?

The oil is everywhere so I really am having a hard time figuring this out. It seems as if all of the shops around here are out of town at the shootout so some ideas / pointers would be great. Thanks.

It really seems like it has to do with the balance shaft. It SEEMS to be originating at the balance shaft closest to the fire wall, then dripping towards the crank pulley where it makes a puddle getting onto the timing belt.

Im still open up for ideas but I really wanna figure out what could cause a leak from the balance shaft.

Go to vfaq and look at the balance shaft elimination page. It is critical to put rtv on the one bolt hole or it will leak. I dont remember specifically because I was a little boozed up when I last looked.:D

I bet that it is your problem though.

When reinstalling the oilpump cover, make sure to either get a new shorter bolt, or install the old pulley and bolt. Put some RTV on the bolt threads before tightening it down. If you do not seal this hole, you will have a massive oil leak.

There ya go. Straight from vfaq.

If that is the hole, then it's not a HUGE deal. I have a feeling it's coming from the other shaft, on the far right side of that picture =/ Ideas ? I'm not really sure why it would leak. Yes I used red loctite on the nut for the oil pump.

More info. If the car is cool, you start it, run it for awhile... it will not leak. You almost have to get it up to operating temp before it will even start to leak. I'm about >< this far from pulling off the front case. We have ok oil pressure until it gets warm, then it goes down the shitter. It starts off solid ( for a used engine) at the bottom line that shows it's ok, but after running it for about 5 minutes, the pressure starts to drop towards the 20% range. I really have no idea what could cause this.

The oil APPEARS to be coming from the crankshaft pulley and/or the oil pump gear area. We all know how oil works and how it can be decieving so if anyone has any last minute info, please let me know

You did rotate the balance shaft bearings when you took out the balance shafts right? Sorry if that is too obvious of a question.

Yea lol.

I'm sure I did because it was a bitch but where would it leak if you forgot that? I thought you just wouldn't get any oil pressure.

Check the oil pump gear and make sure it is tight. If it is loose, it can leak from behind there.

It seems like the crank seal wasn't completely pressed in and there wasn't RTV around that seal or the oil pump gear seal. We didn't even look at the shit until we pulled the motor out. We figured we might as well just take it out and check out some shit and make sure it's a done deal this time. We also put it back in last night. We have to finish putting in a few things, but hopefully the problem is fixed.
