Unless you were tuned quite aggressively on 93 I wouldn’t expect a tank of 91 to cause much harm. Unless of course you did back to back longer pulls that generated a ton of heat. Hopefully you didn’t get sold a hurt car from the start and you can get it sorted out easily.
For real though, are you making boost? I need to have a ton of heat in my PS4s to not blow the tires off. Even rolling into WOT in 2nd, by the time I hit 5,500-6,000 rpm I am fighting traction.
All cars are different but my breathers are dry to the touch still. I’d imagine it’s going to take quite a while for a breather to become saturated to the point of making a mess. In theory though, the VTA can should be mess free.
Pshh you know I am on breathers! You told me the process to gut the factory PCV which I was certain I’d find a way to F up 😂. I don’t smell anything with my car but I also cruise with the windows down most of time and have like no stop and go traffic.
