oil is leacking/sphewing externally... in the engine(pics)

[sportinct26]

well i attack a pic to help me better decribe. when i drive it normal nothing happens but when i step on it the oil starts spewing but i dont know where its comming from... FROM the picture the arrow is where the oil seems to hit cause when i would open the hood that part of it is ALWAYS SOAK with oil. the circle is where im guesing its comming from. what do you think it could be? oh btw the leack/sphew seems to have a force up since it hits the hood.

i have a T78 turbo. wiht stainless oil lines.

im thinking its.
1. the turbo? but does the turbo leack outside with a force?
2. the oil lines to the top of the turbo?

also this isnt related to that problem but my car also STUDDER IN NORMAL ECCELERATION... NOT under boost?

NOTE that i have VPC so its not afm

is that
1. coil pack?
2. spark plug wires?


thx for your help

The only thing in that circle that could be shooting oil up into that part indicated by the arrow is the oil dipstick.

check your oil pressure, make sure its still in spec durring boost, and pre boost

I can't tell from the pic, but is your PCV system still intact? When I bought my car it just had breathers on the valve covers and when you step on it lots of oil vapor shoots out of those things and makes a big mess.

its not from the valve cover... since the breather i redirected down under the car so thats not possible.


and curious what would cause the oil pressure to rise so high that it would shoot out of the dipstick?

and i dont have an oil pressure installed i guess i better invest in one.

 

[steve_mk3]

it could be a rise in oil pressure, but I think what were getting to with that thought is that the system is gettting pressurized. If the PCV system isn't working right your could have abuildup of gasses forcing oil to blow out of the system. Check that your venting is correct. The other thing is that you may have excessive blow-by of the rings that would prussureize the crankcase system..

yeah ill check the pcv vents today and i hope dats the problem.


one question about studder. what could cause my car to studder when i accelerate when NOT in boost and IN boost?

The dreaded blow-by is my guess. Is it was just oil pressure from somewhere it would do it when you rev the engine in neutral.
The studdering could be low compression on the bad cylinder/s. Do a leak down and compression test. The dipstick hole is the easiest place for pressure to escape so it shoots out from there.

i check the PCV breather today and it was almost clogged. :3d_frown: i shoulda known/check b4.


and the studdering is caused by a oil leacky cylinder 2 and 5 i check today.(well i think its whats causing it)

what do i need to fix a leacky 2 and 5 cylinder?
1. valve seal? or is it something way worse busted intenals?

Rings and probably cylinder hone and possibly need new pistons. . If you didn't have any blow by then it could be valve seals, but I doubt it.

what do you mean by blow by?

and will a compresion test show if i need internals or just a valve seal?

blow by is the combustion gas that gets past your piston rings and therefore winds up pressurizing the crankcase when the piston moves back down. The main release for this pressure are the oil passages which lead to the valve cover pcv vents. If you do a compression test and adding a bit of oil into the cylinder improves the results considerably, it's a sign of worn piston rings. If the oil does not help much then the problem is valve related.

Would the results of this test be more obvious with the engine warmed up, or cold?
