Cayman S 2006 Oil Usage

[prestonchris]

Hi

Just had my cayman in for Major service and and full once over from the porsche specialist , up to this point it was using a litre of oil every 700 miles so i was dreading the results of the once over

BUT

Did the IMS check - Fine
Bore Check all bores - Fine

Replaced Air / Oil separator

I've since drove 450 miles and its used 2 bars on the oil level

has anyone any ideas on what could be causing this ??

Cheers

Chris

Apologies my mistakle the IMS wasn't inspected have just cleared this up with the specialist

A full bore scope inspection of the cylinders was undertaken though with the result of - No sign of bore scoring on the cylinders

The specialist I took it to is Cath Burrows in Standish , she's well respected and has been working on porsche for 15 years

Thanks for all the replies , this is my thoughts as well

The specialist has checked the 3 main things for oil usage , bore scoring , air / oil seperator and RMS leak ,

obviously its an iterative process but I'm loathed to keep just "trying" things, for instance replacing the air oil seperator cost me 120 quid including labour and it obviosuly wasn't that

I was just hoping for some "other ideas"

In your position and having tried the obvious causes, I would be looking to have a leak down and compression test done next. If there are no signs of burning oil (blue smoke) and no obvious leaks, it has to be going somewhere and that can only really be past the rings and out of the exhaust.

Thanks mate , going to ask for that done next

If this is the case then whats the issue with the engine ?? Am i looking at a big bill :-(

Yes I am very aware of Hartech and their expertise but Cath worked at Hartech before starting on her own , she's rebuilt 4 cayman engines this year due to bore scoring , for this amount of oil usage to be down to bore scoring I would think the scoring would be fairly obvious , I can't get the car to Cath for a while so was just trying to extract some knowledge before I saw her , maybe someone had been through my same experience on this forum - its not like its anything I can fix anyway


i do feel that Hartech are looked upon as some kind of demigods on this forum sometimes
