Purchased 8.17. Service history unknown. Car looks, operates, runs, and drives like a 9. No noises, creaks, groans, oil consumption, overheating... zero.

In an effort to establish a new "starting point", engine maintenance-wise, I'm preparing to do some preventative maintenance within the next month or so and am reaching out for some insight and direction. In no particular order, yet, I will:

Replace AOS
Replace water pump
Replace spark plugs and tubes
Replace thermostat (low temp)
Replace engine mount
Install under drive pulley

I've read enough on these boards, and viewed enough videos, to be comfortable with these maintenance tasks. Thus, alone I'm confident in pulling it off. Hopefully the same day or over a couple of days. That said...

Is there any particular order in which I should undertake this project? What should I start with... and with what should I end?

Are there any maintenance projects I'm missing to which I should attend "... while I'm in there"? I may have to order more parts.

Aside from the requisite gaskets and seals, is there anything else I should purchase, and associated with those projects, for ..." while I'm in there"? For instance... replace hoses and lines... connections... etc. I may need to order more parts.

Any fluids and filters I should consider while I'm in there? In which order?

Likely I'll be doing this alone, unless otherwise advised.

Any assistance and/or opinion is appreciated. I will be taking notes. Thank you.

Step one to be done during the PPI is remove the oil filter housing & inspect the filter for anything that should not be there.Next remove the oil sump cover & inspect all you can there. If it passes install a LN Engineering full flow spin-on oil filter adapter then change the oil with new oil you have chosen after reading all you can on this forum & Rennlist 996 forum. Do not change the AOS until it shows signs of failing, the new one may be worse than what is on it now.

Thank you, Radium King. Next time I'm under there I'll inspect.

Thank you, BYprodriver... yes... I've read about the AOS. Mine is the original, horizontal top... so that caused me little concern. I believe I'll hold off on that... keeping an eye out for signs of failure or, at the very least, recognizing smoke from the pipe as not good... pulling over... and off. Maybe testing for vacuum on occasion.

Thank you.

I never seen the 1st design in person, I'd buy that from you when you do change it.
