Default sources of high-pressure oil lines/possible leaks on the pass side of the engine bay

CN: huge plume of gray smoke. oil spattered all over the bottom of the car, concentrated on the passenger side of the car (cradle is coated, as well as the pass side of the oil pan, RF wheel well, wheel, strut, brakes, LCA,).

oil feed line for the turbo appears to be intact (as well as not being coated in oil). the oil drain line on the bottom of the turbo also appears to be intact.

half moon gaskets are also intact.

nothing above the turbo itself has any oil on it.

lost a LOT of oil in ~ 1mile of desperately trying to get to my exit (and off the highway), watching my oil pressure drop from ~80psi down to ~ 23-24psi before i shut the motor off and coasted, fearing spinning a rod bearing


i KNOW something let go, but its not internal. theres no oil crud anywhere inside the exhaust tip, so it wasnt burning it.

it has to be something under a decent amount of pressure to lose that much oil that fast. and unfortunately, refilling the oil and starting the motor to try to find the leak is out of the question. i live in a townhouse, and though we own it, as well as our garage and driveway, my neighbors would have a field day with me if i let oil pour down the street. that, and i really dont wanna crawl under the car if its gonna be spraying everywhere.

any ideas?



UPDATE!!! FOUND THE LEAK

ProSport oil temp sender disintegrated.

you have any gauges or other mods to the oil system? Any oil on the top of the block?

Fill it, Lay down a tarp or newspapers, have someone crank it while you're underneath, make them turn it off when you notice where the leak is.

First thing I'd suspect is the oil filter/oil cooler.

if you have a oil pressure gauge, check the spot that is taps into the block. I had two pressure senders fail on me and it did the same thing, but not as bad. check it, that may be your problem.

Jasper, not sure where to get them but my GF's father has these mats that are made for soaking up oil which would work well in your situation. They are actually made of chicken feathers, which after Exxon Valdez, we know suck up oil...

I am having a similar problem, however with much less oil loss. I would check the oil pan/drain plug area, as my symptoms are similar and my leak is coming from my oil temp. sandwich adapter. It literaly has coated everything 2ft. back from the oil filter with oil(mostly on the passanger side), which I can smell burn when I stop. It only happens when the car is warm though and the oil pressure is high...

there's residual oil from a previous leak i had (i attempted to recirculate the breather in the center of the block on the 207. ALWAYS leaked. Ron @ Axis said it'd be fine to just plug it, so thats what i did, and low and behold, no more oil leak (at least for the last ~ 2 days. seems as soon as i fixed one leak, i gained another)

i'll check it, but the area around the filter is, surprisingly enough, dry.

that was my first guess. i figured the stock hardline to the turbo failed (it's been reused at least half a dozen times, probably more, and has been tweaked at least a dozen times, but, once again, oddly enough, the banjo on the head was almost totally bone dry, and theres no cracks in the hardline that ive been able to feel thus far.

already checked it. i have a brass t-fitting on the rear galley, and the oil pressure sender is remotely located via stainless line and -AN fittings. and, once again, bone dry.

this happened on the highway. 1/2mile cloud of gray smoke behind me, so the engine was already up to temperature, and the oil (10w40 dino) was up to temp. (oil temp @ the time of failure was approaching 220*F)

update: yea this leak is freakin massive

took 4.5qt's to top it off

oil POURS right off the center of the cradle, so i was thinking, rear main seal went? but the teeth on the flywheel (looking @ it from under the car) appear dry.


what the hell can dump a 1/2qt of oil onto the ground in ~ 8-10seconds of idling.

You didn't blow one or both(if you have the AVCS heads) of the breather hoses off of the passenger head, did you? With the center breather tube plugged, you're going to have a lot more crankacse pressure trying to get out. You already know how much oil the center breather pumps out.

Otherwise - check valve covers & AVCS oil line (if present). I've had the oil return hose push off of the return line to the engine as well.

my first guess would have been the banjo feed, or return, but if they're both fine, could something be blocking the return in the drain tube itself and be spraying it?

I've screwed up the banjo bolt myself more than once, but never had oil spray like you describe all over. Just a leak to the oil feed or return would dump out, but not spray.

i think the spray was moreso related to the fact that i was going ~ 80mph down the highway when it let go. oil just POURS now. i talked with Ron @ Axis, and he seemed rather sure it was the oil return from the turbo, so i'll be hose-clamping that today, and seeing if that fixes my leak.

hi, yesterday i had the same problem (oil leak), i was thinking the oil hardline is broken, because the 2 washers are good,actually i have a vf 22(wrx 04), so if i install a different oil line(adapter and hose), is most better than the stock oil hardline??????????

gracias

wont know until you clean it all off, climb under there, and start the car.

i still havent found mine. its somewhere right above the steering rack, making it VERY difficult to see/find.

im *hoping* the dipstick perhaps popped out of the oil pan?

you aint kiddin!

it looks like once the actual thermocouple broke loose of the metal barrel, the oil pressure alone broke through the barrel part of the sender. yes, a chunk is missing, but its pushed OUTWARDS from the motor. that piece probably got shot onto the top of the block somewhere, or more likely, right out of the engine bay and somewhere on I-95 north.

thats the only thing I was worried about...a piece of the sender going in, but thats highly doubtful considering the pressure.

I'm glad I am not the only one who'd lose sleep over something that hard to find. I have, myself, a very small leak in that same area, and Im wondering if its my newly installed greddy sender, I RTV'ed it and used teflon tape, and I think there was loc-tite on the threads but I can't imagine where else it would come from.

Of course, I forgot one of the copper washers when I put my braided oil feed line, just like last swap, and spilt oil just like you described, except in a much more demeaning fashion.
