Title: TFSI Intake Valve Issue - I want an answer
Post by: 08micsta on July 13, 2009, 08:35:53 am

Hello guys

Please take a read below:

Now I want an answer... This Snapper dude is annoying me.

Is this really such an issue? How can a normal driver stop this from happening?

Teutonic_Tamer if you wouldnt mind getting involved? Maybe join that SEAT forum and kindly mention your thought on this?

Mike

He is right in that its direct injection that causes the build up and that its caused by oil vapour being recirculated back into the engine via the intake manifold.

On non DI cars this happens as well, but as fuel is injected through the intake manifold it has a cleaning effect and the build up never gets the chance to happen.

AFAIK there isn't a way to clean it other than manually strip it apart.  Although unsightly, I doubt its going to give anyone any concern for a long long time.  The technology has been used by Audi for quite some time with no significant issues.

A catch can would be the most effective way to stop it happening.
