Curious if folks have an opinion of what could be causing this (first pict)
discovered during turbo removal ...
just kept pulling parts out and struck oil!
background that may help:
- EGR was active during this sludge-fest
- it is more than 1/8" of sludge.
- the front of the engine (near the chain tensioner) is mostly dry (pict)
- the intake/exhaust manifolds were oily and wet
- the turbo housing was also oil covered
- the intake on the turbo had 1/2" of build-up in the 'valley' created by the compressed air outlet
- the wastegate was covered with sludge
- the turbo wastegate hose was very very loose on it's fitting into the turbo
- all turbo oil lines looked okay
- the valve cover gasket is a million years old and will be replaced
- the manifold bolts were quite loose (is there a torque spec? do they loosen over time? should they have threadlock?)
- there was also this nasty kink in the manifold gasket between E1 and I1. this will obviously get replaced
- the intake ports are horribly wet and sludgy ... as are the valves (from what i can see into them). Is there any way to clean them up?
- the exhaust ports are just 'sooty' and it doesn't really bother me.
Anyone have thoughts on the leak?
Any thoughts on cleaning it up (ports?)
Basically ... I want to eliminate all traces of this mess while i'm in here.
Thank you all!
