Ok thanks

I’ll record it (try) and upload.

Just for clarity - i am get positive pressure from the small airbox connection that the crank case hose pushes on to

See image …. Red arrow is where positive air pressure is coming from with the PCV hose off

One slight update

Went to a diesel specialist today

His opinion is that denso injectors cant really be refurbished. Just tested and calibrated - he will do this later today.

Also the slight positive pressure on the airbox connector - well this is still true at idle but when i rev, it reverses and starts drawing in.

Anyone with a 2.4 would you mind verifying this is correct by pulling of the PCV hose and seeing if you can feel positive air coming from the airbox side? I would really appreciate it.

I still smell a rat with the cheap turbo. 2010 90 LHD soft top
