K03 wastegate actuator - where to purchase?

[vwnut84]

Looking for the o-ring that seals the inlet housing to the turbocharger for a K03.  Does anyone have a good source or part number for these?  Mine is leaking oil out the bottom and I'm getting tired of it haha.  Thanks!!!

Actually, I was just under the hood farting around with some things and found out that my wastegate actuator is the culprit of the oil leak. 

So, to change topic, where is the best place to purchase the wastegate actuator for a K03?

There is no oil flowing to the wastegate actuator so it is pretty unlikely that it is the source of your oil leak.  Some KKK turbos do vent some boost pressure through the actuator to keep it cool but generally only ones that are bolted directly to the exhaust turbine, like the K24.  If there is a fair bit of oil in the intake then some can leak out the vent on the wastegate actuator in that particular case.  However I'm not sure that the K03 uses that style of actuator given that the actuator is mounted to the compressor side and actuates the wastegate with a rod, keeping it away from heat...

What are your boost levels at?  If they are normal then replacing the wastegate actuator is only going to cost you some money with no actual benefit.

The k03 does have a rod to actuate the WG keeping the diaphragm away from heat.

When I say oil leak, I mean a light spray that builds up on the firewall after a few thousand miles. I am almost certain this is just residual oil in the intake tract making its way to the actuator. I am running anywhere from 10-15 psi of boost, as
I'm still in the stages of playing with the tuning.

The diaphragm is definitely torn though.  Tested with a small bit of air and its leaking pretty good.

If you have ANY oil in your intake I recommend an oil catch can, as it can and will take all of the oil out of your intake tract from blow-by.

Having blow-by is not a bad thing either, I have three 400k+ diesels in my driveway that all have tons of blow-by but all start down to -20c so far this year.. so compression is obviously still up and what not.
