Default Turbo swap,oil feed line leak, won't start or turn over

So I swaped a VF52 on a 2008 wrx. I tired to use the forced performance oil feed line(bad idea) I went to prime the car and the turbo primed fine and has oil. I then started the car and walked to the engine bay to see oil pouring from the oil supply line bolt near the front passenger side(under the hose connecting the airbox to the inlet. I immediatly turned the car off. I then replaced the Forced performance oil feed line with the factory lilne(and added more oil). I then primed the car again....there was gas left in the lines so the car started for a second and then died(about 2 seconds then off.

I am assuming there could be a laundy list of things that could be the problem from what I have read.


Injectors fried?

Fuel Pump fried ? Likely not since I disconnected the plug

So what is happening?

The car has full power(lights accessory, ect) but will not crank over. I tested the starter and it works fine. I have also checked the starter fuse and fuel pump fuse.

Any ideas ? I will see what CEL's come up today when i read the ecu.

Thanks,

Rob

Reseat the connector for the engine bay wiring harness. You bumped it when changing the oil line out.

Probably/hopefully the issue. Turn to the on position and if you don't hear any of the typical electronic buzzing noises or such in the bay ill put my money on those plugs being loose. If you hear all that I would need to touch the car to know more.

Epic win, love when its something free. lol

Have any pictures of the leak? (I'm 99.99% sure I already know exactly what your referring too)
Also when you attached the oil lines did you use new washers? Those are not intended to be re-used. I had a leak in the same location and if it looks like mine ill bet its a washer that was used or damaged. I some how re-used one and took 5 min to swap it and boom no more leak.

Good to hear it was indeed the harness connection. I know all too well the "FML" moment you had.

You said you swapped out the oil line correct? If you're using the stock line still it's probably exactly what he said^
Even if you did use new washers you may have over torqued the banjo bolt destroying the washer.

Luckily you can get a replacement at most auto parts stores(unlike the power steering line crush washers ). Just bring a washer with you to verify size.

Could be under torqued as well..

If you're still running the FP line..good luck. I couldn't stop mine from leaking either. I did have their older version though.

(Opinion)The best off the shelf oil feed/avcs line kit is infamous performance's legacy gt kit - which can be made to work with a WRX.

Yes, I had a hell of a time for a day worrying I fried something in my car since it wouldn't even turn over....should have double checked the obvious

As for oil leak it is coming out from above the AVCS pump/actuator The problem is half of it was stripped out and now its pretty much done for. I need to re-thread it/fix...the problem has been which way...I have seen keenest/keysets, helicoils and then there is permatex. From what I have read the helicoils would probably be the easiest but I am worried about an even bigger leaking issue with drilling the hole.

I found one post on this, Anyone try the heli coil with success besides this one case ?

If you aren't 1000% confident bring it to a machine shop.
They wont charge much and it will be done propeely (provided the machine shop is competent)

If you try it that area will be a one shot deal, not a ton of wiggle room to re-try in that spot.

If it was mine I would take it to a machine shop just because a slip is not cheap in this particular situation.

I have decided to take off the valve cover and avcs solenoid and get in machined and clean what I can without pulling the motor. I will keep this post updated with what happens.

Thanks again for all who have helped this far, you have given me support and kept my mind at ease knowing this can be fixed.

Smart.

Glad to help, looking forward to seeing if this will be the last little issue before you can go enjoy that thing. Honestly for me the little issues ended up being half the fun because when all is said and done you learn a LOT about the car and can tell when anything is slightly off.

Exactly why I agreed about that being the issue, not my first rodeo.
