So the first part which is obvious is the OAS will be changed, I planned on changing out the Spark plugs and coils, installing a new fuel filter aswell.

I did notice that my rev counter sits at 500rpms or so when you switch off the car and reads around 500rpms to high whilst the car is running, any ideas on how to fix this as it seems to function correctly aside from being miscalculated from zero

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I work at a dealership and they took in a base 2002 Boxster 5 speed as a trade, I was able to grab it for a good price. It seems stock aside from a Fabspeed Catback Exhaust. After getting it the first thing I did (before even driving it) was do an oil change and got the AC working. Yesterday I was finally going to take it home and pretty much 2 miles into my drive the OAS went out and blinded everyone on the street lol.
Was planning on making this my project and get it running well and using it when weather permits but seeming as this happened I decide may as well remove the engine and do what I can whilst its out an accessible.
So the first part which is obvious is the OAS will be changed, I planned on changing out the Spark plugs and coils, installing a new fuel filter aswell. At the same time I will look around for any oil leaks and replace any bad gaskets.
The car had a seemingly high idle so will degunk the throttle
Just wondering what else I should do to the engine whilst its out? that is relatively cheap or may pop up at a later date?
The engine has approx 127k Miles
I would replace every vacumn line while you have the engine out , also consider replacing the starter . It's a LOT easier to change the starter with the engine out than when it is in the car .
Water pump... thermostat... motor mount... transmission mounts... that breather valve associated with the AOS, near the front of the engine... just some of the easy stuff.
connections between engine and oil and anti-freeze tanks. AOS. IMS and RMS. Motor mount, Belt. Coils, plugs. Clean throttle body. Clean MAF. Header bolts, studs. Air cleaner.
Where do you stop?
Thanks for all the suggestions, sorry for not updating this, unfortunately they didnt get a free lift and I got tired of waiting so figured it was already broken let me give it a shot. After watching multiple videos on youtube I jacked the car up and got working on it. Initially I couldnt quite see where the bottom below even was so thought let me yank on the AOS and it literally popped off with no effort.
Turns out maybe the clamp someone previously used was loose or not snug due to the amount of crud around it, I managed to get the new one on and was surprised to see no indentation on that bottom pipe for the clamp to grip to.
After I got everything put back together I cranked the car and left it running for a few mins and it was still smoking so removed the throttle and noticed there was alot of oil inside of here, the breather pipe, plenum and the intake mainfold so after cleaning out as much as I could took it for a drive and after about 25 miles it runs alot better with a steady idle
