Head gasket or possible egr cooler?
« on: July 05, 2021, 03:24:32 am »
Got a 2007 2L tdi single cam PD lump. Been having issue with the pressure pushing coolant out the cap. Tonight I was able to get a pressure tester hooked up and went for a spin. As soon as I hit a big hill and gave it plenty of right foot the pressure rose, eventually went over 20psi!

Now my thinking is the head might be lifting a touch under boost but someone suggested it could be the egr cooler which I'm reluctant to think possible. Only coolant I seem to lose is from the cap itself.

My experience of a cracked head caused constant pressure and that was without a turbo in a petrol car with less compression so I'm kinda ruling that out.

Anyone have any other input?
