Ok thanks for that Chris.
Dunk my car has done just over 60k miles, but as you say it's 16 years old now, so they could probaly do with changing.I'll change these stem seals when i fit my new cams.Any idea on a price for a full set of these stem seals from MR T??
Regarding my turbo.My mate recommended CR Turbo Engineering, as he as just informed me that they overhauled his (Signature Series) HKS T51R KAI, with no issues.
I have phoned and they told me they can change the seals no problem.They said they will strip the turbo down for inspection, and providing the main componets are ok, they can fit upgraded step gap oil seals, perform a mod to improve oil flow and rebalance the turbo for £395 + vat + carrige.Also they will include a 1mm oil feed restrictor adapter, as recommended by Garrett.
So going off my mates experience, i will give them a go with my T04Z.
I will post an update on the progress when i know more.
Thanks guys
Steve
