997.2 Turbo 9A1 engine

[65368]

I Have been warned that the 997.2 9A1 engine has a potential problem with a 'Sleeve' mounted inside the Inlet camshaft moving and cutting off the oil supply [the camshaft is hollow]. apparently this can be fixed by 'pinning' the sleeve. does anyone know about this?

I've spoken to the Warranty manager at my local Porsche Centre and this is a new one on him. ( and you can't say that very often!) Where is your source for this?

I was warned and then Googled it [dangerous I know!] but found a few on YouTube; https://www.youtube.com/watch?v=K9CjfwEXPAA

The Reason for the question was my 997.2 Turbo S with 60,000 miles has had an oil seal go on the LH Turbo so the engine has to come out to change the oil feed pipe and if this was an 'upcoming issue' now is the time to get it looked at!

Isn't the 6speedonline thread about a 2007 turbo? My Google searches seem to throw up references to 997.1 "spun" camshafts not 997.2? The famous "bulletproof" Mezger not the DFI gen 2 lump. Must confess to being a little confused. Do you have any links to 997.2 specific threads/articles?

I have to admit I had not looked closely as to whether the engine was Metzger or 9A1 but I was told the Camshaft design was the same and could suffer the same problem. I now suspect I over-reacted but Having had the RH turbo push oil into the intercooler due to a partially blocked breather, and now the LH Turbo oil seals failed [and I was told many times that the Turbos 'never fail'] I am now rather more paranoid than before [:-]
