Jacking front of car too high causes smoking?

[oasis]

This happened after doing some boost leak testing and I'm wondering if running the car with the front jacked up can cause the car to burn blue smoke when revved, due to turbos not being able to drain properly?

Def not.

Never happened to me but maybe you pushed some oil during the boost leak which is burning off. If it doesn’t go away you got something else going on.

Damn, ok. Not looking good.

The first few times pressurizing the system I forgot to cap the y at the pancake valve and didn't remove the oil cap - what could cause oil burning then? Only thing I can think of is turbo oil seals but can they get damaged this way? Btw I couldn't build more than 5psi (give or take a couple psi) due to boost leaks during this time.

Boost leak testing within your operating range is safe. I usually just do 15 cuz those things can pop off.
I'm not sure that I would even hear a boost leak at 5.

You pressurized your crank case by not disconnecting your pcv and leaving the cap on. Just drive it until you burn the off.
