Anyone any ideas where this could have come from?  Never seen it before.  Suddenly shows up around the edge of the silicone hose that is clamped to the turbo.  I thought it was oil, but I touched it and its sticky like molasses..

Not knowing if you have a oil catch can fitted to filter the oily air from the crankcase and upper engine area and assuming you dont have one fitted my

initial feeling is that its a oil / air residue build up on the tube wall that has run down and has started leaking out. If it is oil the sticky feel could be as a result

of the intense heat generated in that area affecting the oils charactaristics.

 

Many years ago when I was an apprentice my Suzuki 2 stroke (20/1 petrol oil mix) m/bike would dribble what looked like tar out of the twin exhausts and id have to

pull out the baffles and clean them with caustic soda on a regular basis.

However in worse case (I hope not), the turbo seals have popped and the oil carried up, heated / and is leaking out.

 

Good Luck

Hi Silver Bullet,

 

Thanks for the reply.  I do not have an oil catch can.  I still have the factory piping so the oil is recirculated.  I will pull that intercooler pipe off tonight and have a good look inside.  Are there any other symptoms to know if the turbo seals are shot? 

 

Cheers,

Samuel

NP Samuel,

Okk, before i fitted my OCC I pulled off the black plastic "Hockey puck"  thats sits on the top of the fat turbo intake pipe, put my finger inside and felt a slight black oily residue on

the pipe walls. I did replace all the charge pipes (post turbo therefore pressurised) and a small dribble of oil came out of the intercooler outlet prior to the change, thats normal on a std set up,

a bit more on a higher mileage engine.

 

As regards symtoms:-

1/ Sudden Increase in engine oil consumption.

2/ Noticable loss of performance leading to eventual engine mis-firing as plug/s oil up as they try to burn off the excess oil in the fuel/air mix.

3/ Blue tinted exhaust gasses (White colour exhaust gasses are ok, this is normal and just condensation burning off in the cold weather, they all do it).

4/ Turbo eventually starts making new sounds, as bearings overheat and begin breaking down.

5/ Possibly a oily fleck residue starting to appear on car body around exhaust pipe.

 

The thing is, as this engine operates using a "closed air system" ie: crankcase / camshaft gasses are fed back to be burnt off,  hence the "oily stuff" goes back thru everything,

one way valves, intercooler, all sensor bodies (post turbo), and finally throttle body.

 

Good Luck

What does that Hockey Puck actually do?  Is it essential to this engine?

Ummm yes, the parts are there for a reason.

Its official title is:- "Crancase Ventilation Pressure Control Valve"

Part Number: 06A - 129 -101 D

Function:- As the name implies it allows excess crankcase / upper engine air pressure to be released back into the

engine intake for combustion in a controlled way. (Item 11 below).

 

NB: Try using the search function first thats where I found this useful diagram
