Is it just me... or is that a laundry list of throwing parts at a car?

Best wishes on a less costly outcome.

Looks like they used "new" parts to test with, as they refitted all of his original parts.
Testing with known good parts is one way to go, if you have that resource.

Thanks for all the comments, very useful tips.

I spoke with another boxster specialist who said it could be the variocam shaft? Which parts cost 375 plus VAT from porsche plus some seals etc, incl labour it's about 1k pounds total. If they diagnose and it's what they suspect they will just take the diagnosis cost off the fixing cost. That's reasonable right?

Is there anything else worth doing whilst they are there? They said it will cost more on the pre 2000 model it's more difficult to access?

That invoice was from the previous owner. Is it just me but it look like the garage was taking him for a ride? I don't think all that takes 20 hours labour? Surely 1-2 hours max!

I'm not a trained mechanic but think I could do it for all that for less than 20hrs .

Maybe it`s just me, but I`m not sure what the specialist is referring to as a variocam "shaft". The variocam unit does not have rotating parts. Looking at the price perhaps he meant the solenoid, the price seems reasonable. To replace that you need to pull the head cover, so if it tops at 1k I think that`s pretty cheap.

Thanks for your response. Yeah I think I must have misheard it it's the variocam solenoid. Would that affect 1 bank or both sides? Are there 2 solenoids?

There`s one at each bank.
