Welcome to the forum and 986 ownership
I am not a certified IMS expert, but here's my advice.
- Don't Panic.
- If you find that you are are panicking, have the car flat-bedded to the nearest independent Porsche professional for an LN IMS pro or Solution. Seriously, these are great 'driver's cars' and if you are scared to drive it, fix it now.
- Take an oil sample and send it for an oil analysis. After receiving the results, refer to #1 or #2 as needed.
- Change the oil and filter, check your tires for wear and age
- If you have not had a pre-purchase inspection done (PPI), consider a post purchase inspection. There is a lot to learn about these cars if you plan to DIY maintenance.
- Drive it hard, have fun, consider joining the PCA,
Post a picture. We all love pictures of Boxsters.
