I have a major oil burning issue...help!!

[ywgbandit]

So I went out today to do a new Datalog after finding that the nuts that came with the S280 turbo had backed off and the subsequent manifold to turbo leak may have caused a false knock. I replaced the nuts and studs with OEM and torqued everything down and went to do a Datalog. When I backed off the throttle after hitting the 7k limiter I got a huge cloud of burnt oil smoke out the tail pipe. By the time I got home the car would not idle and blue/grey smoke is pouring out the exhaust as I drive. I emptied my new catch can and I got about 2 oz of oil out of it. Any ideas as to what damage I may have done? No codes showed up on the AP???? It's burning a lot of oil!

Check your charge pipes and see if they are full of oil.

You could start by pulling the plugs to see if oil is in any of the cylinders.
If not or in all of them, then suspect the turbo.

I'm pretty sure they are, but why? Where is the oil coming from?

I'm going to do a compression check at the same time.

If your charge pipes are full of oil it is coming from the turbo.

If oil is in no cylinders, oil may be going out the exhaust side of the turbo.
If oil is in all cylinders, oil may be getting by the intake side seal of the turbo.
If oil is in only one cylinder, you are in deep doodoo.

@Ford ST , you are very correct.
I just like killing two stones with one bird. LOL

Besides, you don't need to get under the car to pull the plugs.

 

[ywgbandit]

I hope not, it's a brand new S280! The smoke didn't show up until I backed off the throttle, it wasn't burning any while at WOT.

@ywgbandit,
BTW; Very sorry to here this has happened.
However, now that you have peaked our curiosity, please report back and tell us what you find.

So it pretty much sounds like one way or the other it's a seal in my turbo?

Unless of course, oil is in only one cylinder, then it could be a cracked oil ring (or worse).

When I blew my motor this happened. Black smoke out the tail pipe couldn't even drive it home. You probably had the same thing happen as me, you chipped the top of the piston ring land off. Your gonna need new pistons.

Looks like I blowed her up real good!
Compression test by Cyl, cold engine:
#1: 145 psi
#2: 140 psi
#3: 145 psi
#4: 65 psi

Can't imagine anything but a blown piston causing the low compression and the excess oil smoke, unless someone has an idea?

Looks like I'll have to save up for a short block.
Looks like I'm done for the summer!

Sucks man. At least you seem to have a good attitude about it! Gotta pay to play.

 

[ywgbandit]

Can't change what happened, so I either sell her as is or fix her. I'm thinking a Mountune short block is the way to go, not sure I want to put the same shit back in that failed.
I was only running 24 psi peak boost with my S280 too....pretty conservative I thought. Oh well, nobody got hurt or died.....except my wallet!!!

I'll take deep doodoo for $4K Alex

Make sure you check the valves these engines are interference engines and there's no telling how that piece of piston fall off affected them.
