I need some insight from the "experts"!
I have an 05 which I just purchased. It had a blown oil cooler, so I took it to my guy and had it fixed.
In the process, I added an EGR delete, new cooler, Coolant filter, and head studs. Figured while it was apart, it'd be best to make it right.
The system was flushed 4 times and the new coolant looks awesome, with no more signs of the infamous grey goop.
My issue is, twice (after repair) the degas bottle has blown over. At first I thought it may have been slightly over full, and just overflowed, but on my way to work today, it happened again. I just purchased a new Napa 16psi cap to eliminate that...No tuner, didn't overheat...
Any suggestion, other that a bad HG? The degas was holding a steady 5-6 psi on the test drive last week. Just wanted to ask, as my mechanic is 1.5 hours south of my home.
