Oil coming from CAC/aftercooler vent.volvo Tamd22

[Jamie W]

Hi everyone.

 

Just finished running in rebuilt engine, never trusted it tbf after cowboys had it.

 

 

And whilst out oil pressure dropped 20%, whilst at 90% throttle.

 

And theres oil coming out of the aftercooler/crankcase vent hole. About 1 litre, continues dripping.

 

I cant get my head around the routing, and how its ended up there. Was at high revs it happend.

 

Im guessing either turbo or head gasket.

Took turbo off. And theres oil in the large black hose.that goes to the CAC

 

I assume turbo gasses should exit here?

 

So prob the turbo seals?

Trusted the wrong monkeys :-(

 

Should name and shame really!

 

Just Spoke to a turbo specialist bout a rebuild.

 

But as theres hardly any play in the turbo.

 

 

I agreed that its more likely the crankcase pressure, stopping the the turbo oil draining at high revs.

 

Since they rebuilt it, blow by has been a choo choo. And it gets bad at high revs (blew oil cap off). So obv the new piston rings weren't done correctly.

 

Oh well. Engine out again.
