OM606.962 Valve Float @ raised boost?
I think my valve float issue is exhaust pack pressure related from the turbo. I recently purchased a bigger VNT turbo but it will be a while before I can install it. My thought is that while the existing gt2056 is great and spools instantly, the exhaust side is too restrictive with full fueling and high revs on the 606. I now have a GT2359 to test and I'll be able to see what the exhaust back pressure difference is and if that cures the valve float.
The fuel problem cam be and must be repaired by using a series pump 250lts min at least.
All engines with superpumps need one.
The valve floating is another matter wich can only be solved with stronguer springs. Or running lower EBP.
There are ways to deal with it . Vnt generates a lot of EBP.
And gt 20 is just to smal for 606.
