I am awaiting delivery of an MT 2017 718 Cayman S (used) which will be the most technologically advanced vehicle I've ever owned.

Concerned the ...

Wednesday 10/14/2026 | 2006 | 911 Carrera | Engine
I watched a video on this site advising that if you were looking to buy a Cayman bore scoring was less common in the base models in the pre 9A1 engines. I am looking at a base 2006 carrera. Does this apply to the carrera cars too?

READ ANSWERWhat oil pressure sending unit do in need to hook to a VDO guage
Friday 10/02/2026 | 1999 | Boxster | Engine
I have replaced my stock oil pressure sending unit with a 1999 911 one so I have a pressure gauge. I connected a sending wire to a VDO International II gauge. At start up the oil pressure is fine at about 5 bar. When the engine warms up, the pressure maxes out at about 40 psi at around 3000 to 6000 rpms. It idles about 4 or 5 psi. Do I need a different sending unit? The gauge is 10 to 180 ohms. a direct reading on the sender shows 44 ohms at idle warmed up. There is no resistance in t ...

Hello,I recently purchased a 2005 911 Carrera with 77,000 and I noticed that sometimes at idle seems to have misfires. Vehicle stored misfires faults on different cylinders.

READ ANSWERHow do you vacuum fill the coolant fluid on my 981 Cayman, Specifically how do you get a seal
Monday 09/14/2026 | 2014 | Cayman | Engine
I have been working with Pelican Parts and ECS Tuning to find out how to use their tool vacuum fill tool to change the coolant in my Porsche 981 Cayman. The attached file was sent to Pelican and ECS weeks ago and asks the question of how to connect the tool to the coolant tank and get a seal. I think a lot of PCA readers would like to know the "trick" on how to get a seal, and why Porsche makes that tab on the filler neck that prevents the seal with any normal plug. Please can you help. ...
