Emotional attachment to 18.5 year old RX8
I put the BHR Yukon coils and fuel pump in at 23k miles and Bilstein b12 kit at 35k miles while it's at 37k total mileage.
That was after track days found misfire which could kill engine and the stock weak shocks which had different height measurements
People said to weaker spring shocks but answer was better air shocks for 24 inch all around.
So I was able to fix car and use 1/2 ounce per gal premix oil to further save engine.
My yearly hold cost is approx $1000/year taxes and insurance all these years so it's a drag, but I could get what 8K maybe and besides Imma crippled and can store tools in it next to my daily 2014 BMW X1.
At 73, I coud go any year but might have 20 left.
I've never had to repair anything except the defective 6 speed auto trans I found 14 years ago at track day.
Yes, It's the dreaded 6sped auto which you'll tell me is ****, but I can connect battery after 3 months storage and drive on road for 10o+ miles and get 25 to 27 mpg if no AC on.
My dream of fixing this car from listening to RX8 club is priceless.
I'd rather give to some excited relative than someone come find my worth like at a garage sale.
Do you have cloth seats? It's usually static charge from your clothes rubbing on the synthetic fabric. Can happen in any car and it's worse if your clothes are also synthetics. You can grab the roof, A pillar or some other metal part of the car before stepping out to discharge

If done incorrectly, catastrophic-engine-failure-ly.
Not worth it for vast majority of owners, just something people chase because rumor mill and social media paints porting as a golden ticket to power when that's not really the case with the Rx8 engine.
I got a fun one, do we even need the sump oil vac line? I was questioning catch cans between the sump and the intake manifold......but then got thinking why not just put a filter on the oil fill neck or on a hose in a better location if it mists a lot.
The only thing I could think was maybe the oil seals get helped by vac to seal? I saw some cases where this was mentioned for piston engines, but I think in our case its mainly the springs doing the work since our piston rings don't exactly have play up and down. Vacuum cant necessarily pull the oil rings apart to seal better, they are a solid metal donut and cant stretch outwards by vacuum. If anything the rotational/frictional forces probably force the oil control rings to trail behind the rotor which is where the oring helps make up for the seal. I doubt vacuum would come close to overcoming those forces.
Maybe the oil mist could be flammable?

I won't touch on the other stuff like any combustibles coming up from the oil pan or any of that stuff, I'm just thinking of the biggest reason why I probably wouldn't want oil potentially just burping out of my motor and maybe onto the road surface.
There are instances where our cars burp oil. If your potentially dropping it directly into the bay it's going to get everywhere and could drip downsides of the motor, if you're dumping it under the car well then you're just putting yourself in a situation where you could burp oil, drive directly over it, and then put yourself in a predicament where you no longer have traction cuz you Mario kart banana peeled yourself and youre sliding. Containing the oil and disposing of it in whatever method you choose by capturing it in the catch can is the most advisable thing could probably do, and vent that can to atmosphere.
