I was having an issue with a CEL of p0117 which is bank 1 lean at idle. So I replaced my o2 sensor with no change so I checked the check valves and they were cracked with pin holes.
2:49 exhaust manifold is broken. A huge crack between the three bolts. That causes the leakage. Oxygen from the atmosphere comes through that crack and makes lambda thinking that there is non-burned oxygen. Computer puts extra fuel.
chris griner no there’s no vacuum pump for the brake booster. It Relies on intake manifold vacuum when the throttle is closed . There’s an electric air pump that comes on cold starts and pumps air into the exhaust to help heat up the catalyst for emissions
Thats not a good idea 💡! Now when you hit boost the pressure will go into the crank case and the brake booster ! Those check valves are there to allow vacuum to be pulled when throttle is closed and and to keep boost pressure from entering
Thats correct this is the stupid idiot young kids who dont know what they are doing and watch too many you tube videos and listen to their dum ass friends
omg thank you for simplifying the f@$k out of this. most definitely appreciated.
How will work fuel pressure sensor in fuel line when he take boost pressure from manifold?

Now that 6 years has gone by how'd that work out for yuh?
Nice video,some pic or diagram of finished vacum delete?Thanks and sorry for my english.
Vent hose on the bottom of the coolant bottle, where does that go?
Is there any video tutorial for 2003 audi a4 b6 1.8t SAI delete? Kinda not familiar basing on VW and older model of audi. Much appreciate it.
looking for that one too lol
Can you show the lines after you've done it? pleeeeaaase
Four year old thread, sorry, but wasn't there an electric vacuum pump for the brake booster?

It's the long fingernails guy, he just cut the nails..
Sounds logical to me so I won't be doing this.
what suposed you win without vacum?
Is your car a Quattro? If so then we have the same car.
Thank you!!
Is this the same as a 1.8t atw engine?
No, I believe AEB is drive by cable and has a different pcv system.
