What is this? (New info added please help)

[775TSI]

Below are some pictures of the random screw with fluid around it i have been talking about. Its behind my alternator under that very large aluminum line right below the head. You can see the screw clearly in the 1st picture right above the top of the alternator. Its a phillips DISCUSS!

if im not mistaking that thing is for a bracket of some sort like maybe the stock oil feed lines that bolts to the block.

Looks like a wrong timing belt cover bolt to me.

 

[2GJeremy]

a bolt that doesn't look like it needs to be observed, the liquid around it looks like lubricant for the tranny or bottom engine.

 

[775TSI]

what do you mean doesn't need to be observed? Its a random bolt bolted into my block with fluid around it. The closet thing to this is my head (above) and timing cover (right). Transmission is on the other side of the engine bay. There are 4 colors in this picture you cant really see. One is brown, other is black, third is lime green, 4th looks like soldering very shinny almost smooth looking aluminum material.

I don't know about wrong, but I'm also going with a timing belt cover bolt. Particularly number 15 in this picture:

Post a farther away pic than draw a arrow to where it is cause im a little lost on the exact positon we are looking at.

brown is rust, black is sledge, green is antifreeze and the last one is non lubricated metal. that bolt is one of many to a cover in your engine. whatever the hell made you pick THAT one out of the other hundred in there is beyond me. it doesn't look stripped, crossed, wedged, broken or anything. leave it alone especially if it's that close to your head and you don't know what it is .

I picked this one because its the ONLY wet spot on my entire engine. My car has zero leaks but now this comes up and i am on the verge of a rebuild. I have googled several hundred pictures and have yet to find this 10mm phillips screw on any other 1g or 2g

 

[19Eclipse90]

Whoops. I was mistaken on which bolt you were talking about.

That little Phillips bolt is a plug for the hole used to drill through the balance shaft bearing bore into the main oil gallery.

 

[775TSI]

Oh p.s. Could that fluid be coming from a blown head gasket? Oil and coolant in the same path is never a good sign seeing i have nothing over there part wise.

 

[WES_393]

That's just a plug. They are put in to block oil or coolant passages after manufacturing. I would try tightening it a bit as it looks pretty far out

Oh thank god. I was thinking someone got creative and tried to patch something with a screw. Moving on to where the fluid is coming from now.

that's where the fluid is coming from I imagine.

 

[775TSI]

well that would explain my low oil pressure and all but the fluid if you look closer it appears to be coming from more north and of course heading south.

3 months ago when i did a comp test 4-3-2-1 i got 152 156 153 141 <-- thats the bummer. I got a fluttering vacuum idle my boost hits 15 drops to 14 and carries all the way through RPM range but with a nasty and i mean nasty missing. Check the plugs they seem fine but i ordered BPR6ES which should be here tomorrow. Keep getting a CEL for fuel trims, just replaced o2, ecu temp, gauge temp, thermostat, TB, IACV, TPS, MAS, Injectors with OEM 450, intake manifold gasket, added a Apex'i SAFC, plug wires, fuel filter, oh and the coolant cap. Maybe more not to sure at the moment but this is all within 3 months.

Someone DID get creative and mickey moused that.
A philip screw for an engine plug?
Really?
Slowly remove it and if oil goozes out then tighten it all the way in, if not take it out and throw that shit away.

 

[2GJeremy]

like wes said, tighten that bad boy or go get a new one from the toolbox.

Beleive it or not it's stock. My 4g64 sitting on the engine stand has about 5 of those in it at various places. I took them all out and resealed them with liquid teflon. Just goes to show no manufacturer is without cut corners. Take a look at your ECU wiring sometime and tell me the brown packing tape around the O2 sensor wires doesn't look like a grade A hack job.

IT is obviously leaking from a higher point. The balance shaft bearing blocks that hole off anyway so nothing would come out it.

 

[i27457]

Yeah maybe the leak comes from one of the water lines around try and check that, did you just bought it?, I think I saw that talon on craigslist not too long ago.

 

[775TSI]

Long ass story on that part, and yes all my fluid passages check out except my head, cant see around that point.

 

[Mach1TaloN]

Yeah, i know when i done the timing belt on my 6bolt, there was a similar bolt on the rear balance shaft housing, you had to remove it and make sure a screwdriver could fit past the shaft in the hole while all the timing marks were aligned. Because if you done it backward, it causes crazy vibration. Anyways, to the point, i imagine that bolt hole has the same purpose. Probably replace that before it becomes a bigger problem. An ounce of prevention is worth a pound of cure.

 

[ed1380]

It's from when they drilled the hole from the balance shaft bearing to the oil galley

The plug in the back of the block with the Phillips head is NOT the plug you remove to check the phase of the rear balance shaft. That is just to block off the hole that was drilled when they drilled the oil holes. There is no oil pressure behind it, just the back of the balance shaft bearing. There is no reason to replace a random plug that isn't leaking. The leak is at a higher level than the plug which has been mentioned a few times in this thread already.

 

[Mach1TaloN]

My bad, thought it was only suggested that it was leaking from above. Also, about the rear balance shaft, its been a while! Lol, cant remember exactly what it looked like.
Well then, given the new info, not worth the hassle to disturb that plug.
