Subaru engine cleaner on an Inline four.
Sup guise.
Just read the can for the "subaru upper engine" cleaner and yea, that method suggested would probably lock an inline four, lol.
What's the best way to use this stuff? I presume;
1) Warm car up
**TURN CAR OFF**
2) remove Intake pipe off the Throttle body, spray a decent amount on the butterfly, open the butterfly, coat all around the inside of the intake manifold decently (Give or take 1/2 a can)
3) Let it sit for 5 odd minutes
4) Start her up, obviously it'll take a while to start. Give it a bootful for a few seconds, let all the shit vent its way out.
5) Rip off the Vac line for the PCV ON the intake manifold, and spray into there keeping the revs high and not letting the car stall. Also being careful not to flood the engine with the shit (AKA Be moderate and take time to use the other half of the can)
6) let it run until the smoke stops
7) Drive it, see how it goes, then do a usual service.
