Not according to my mechanics stethoscope, but who knows at this point. It is the updated style, but I guess that may not mean much…
I drove it again today from cold. So the first cold and low speed drive since I had redone the DVs. In urban locations where there are structures on both sides to hear sound bouncing off, it sounds excactly the same as before. At idle it’s arguably quieter. But from just off idle to about 1500 it sounds like rocks in a box rattling around. After that it’s smooth and quiet.
It also seems smokier or smellier than before but that’s not necessarily true.
All injectors were redone by greazzer a few thousand miles ago, so I know they’re good, and all lifters are new INA.
