At 245K miles on my BPY there was around 13mm (1/2" SAE) of space on each valve of the 8 of the intake. The cold winter starts were almost not possible in Maine USA.

Surprised you don't have a catch can setup. Especially with the amount of crap that these D.I. engines build up and recirculate. They make a substantial difference. I.E. makes a nice one. Good call on the cam follower replacement. One of the only things that I used to see on these cars when I was at the stealership was varying degrees of carnage inside the chain cover. Smashed follower, flat spotted cam lobe, chewed up/ grinding marks inside the cover, etc. Some people hear the noise and just let it go... 😒🙄 The only other things that were notorious to replace at the stealer we're the PCV, manifold as a complete unit, and the purge solenoid.

We replace the Teflon with graphite versions. We also replace the filter baskets and top seals also.

[@c4lho888]

No all it does is release the pressure when it gets high - when the injectors stop firing on over run / throttle closed

Good tips for the high pressure pump and injection sensor... 👀👍 Another situation, I am currently changing to take the catch can and avoid this problem but I also have the EVAP pipe/connection (system canister blablablá) here....

No, if you are doing a RFD , then also remove the divider plates in the head. They are only used in conjunction with the flaps.

I'd always suggest sticking with Bosch electronic devices on Bosch engine management. Any deviation generally causes issues.

[@jonathanpinlac2030]

Nice video, I have a question though, what did you do to the Intake flap connector since you removed the entire intake flap module? Did you just leave the cable dangling? During ignition it'll need that to reset the flaps etc. Even if you did the Flap delete, when starting the car, did you manage to bypass that?

Hi pal, I leave the connector in the bay, just tucked away and I then code out all of the runner flap strategy and pcodes.

@@DecimalTenths I left mine on connected eventhough I did the RFD on mine. Reason is I think in VAGCOM, you cannot disable this feature as it is related to emissions.

There is a potential for a lack of airflow, and therefore a small amount of additional fuel, however the fuel trims will take car of this and show so a logging session would most probably identify the cause.

I Hope you have to fully fill your Highpressure Pump before start it !!!!

We find that we are changing so much of the characteristics of the engine, and increasing torque over the full rpm range, that the flaps then become redundant.

[@RacingLew]

Would you recommend doing them all at once and then getting car mapped or would it be possible to do them individually and then get it mapped after they all done ?

The carbon cleaning? You'll want to do them all at once given that most of the effort is removing the manifold. Wouldnt want to waste your time doing that multiple times.
