Turbo Pipe

September 28, 2011

Hi,

I want to know that the pipe which goes from air filter to turbo, and fitted on turbo inlet pipe, how tight that should be?

When I tried to clean EGR valve, I had to take that pipe off, and I found that it was not really tight at the juction where it attaches to turbo pipe.

Also from this big pipe, a small pipe is going somewhere which is again not very tight. (when I removed this small pipe, these was a drop of oil).

Questions;

1) How tight should be hose which attached to turbo inlet? (please see number 1 in the photo)

2) How tight should be small pipe going from this hose to somewhere?

3) Should there be oil drop around small pipe where it attaches to hose? (see number 3 in the photo)

Thanks.

You must have been typing at the same time as me!

Can't say I know much about turbos, but I do know the air pipe shouldn't leak between the air filter (and MAF sensor) and the engine.

What I did with mine was to remove the hose, wrap some high temperature resistant rubber round the turbo tube until the hose just fitted back on and the clip could tighten it in place. I'll be putting a new hose on when I get to work on the turbo itself.

The small pipe is the engine breather, and I'd expect a drop or two of oil to make its way there, others may disagree. I think the small hose clips indicate it doesn't have to be a really tight fit. That hose will have low pressure inside which will tend to improve the seal.

Hope yours doesn't end up like mine.

hi mate

i suppose you talk about the pipe i am thinking about.

ok normally the engine must be saved from an internal explosion from an exhaust gases pushing thru piston rings in the crankase. for this reason a vacuum must be maintained in the engine both from sump and from rocker arms side. the meaning of this pipe is to pump possible pressure increasing inside the engine and forward them into the compression side of turbocharger that will compress both these gases and an air and deliver in the combustion chamber via inlet manifold.

It is understood this pipe must be tighted by means of hose bands. Cheers/Igor
