The oil filter housing? How's this? Except he thinks the N55 is a twin-turbo; which it is not...

Yea I just uploaded some pictures. Is that the problem I'm looking at ?

[ezaircon4jc]

Looks like it to me. When I had that issue I also had oil pooling in the depressions by the cap. Yours looks like a more serious leak and I would take care of that before the oil contaminates the serpentine belt.


Taking a closer look at the pictures, it looks like the belt already has oil on it and is contaminated. While you're there, I would change that also and do a through clean-up of all the oil.

Yep exactly what I was thinking, I had oil on whole front of engine. Even on the charge pipe connector, the belt will fling the oil everywhere. Take off the engine cover and check around the oil cap it will drain straight down. I ordered a oil cap off ecstuning. It seems a different design.

Extremely common leak from the oil filter housing and oil cooler housing gaskets. Upper radiator hose, belt and tensioner should also be replaced.

Potentially the thermostat hose as well "mickey mouse" but that isn't clearly seen in your pictures. It also usually gets wasted from the oil contamination.

Then why's it say twin turbo

His title says "twin turbo", the engine cover says "twin POWER." The N55 utilizes a single "dual-stage" turbo.

Serpentine belt shredded.... was this because of the leak. Now what will need to be checked and replaced any input? I will Upload pics when I get home

I actually did check that , I can see oil residue all over
I put a napkin under to see if it's still leaking under nothing.

100% your failure to correct the issue in a timely manner just got a lot more expensive. The belt breaking is the normal failure that brings severely neglected leaking cars into the shop.

The correction now (beyond what I posted earlier) is pull the harmonic balancer and inspect/replace the crank seal. Drop the engine oil pan and remove belt material from the sump. Pick belt material out of the timing chain. Remove the oil pump pickup and flush belt debris from it.

Sorry to hear man. I was coming here to say "fix it before your belt snaps". Sounds like I'm too late, best of luck OP.

[F10535]

This what was left

[F10535]

honestly if it shredded and you have the capability of pulling the pan I would. you dont want your oil pickup getting clogged or any material getting into places it shouldn't

I do have the capability of removing it the pan but what are the steps to it ? Do I have to replace the bolts to the pan ? but might as well do oil change also
