HR motor mount bottoming out ....

[Jerryl]

So, basically, ........ from the markings, it is clear that the mounts are contacting/resting on the saddles on my set-up.
Anyone seen this before?

Yep, that's where it is supposed to touch.

Basically the only thing associated with the motor mounts that could cause the false knock is if the 2 long bolts are not tight enough. You REALLY need to clamp the side plates of the motor mount against the frame pad TIGHT! Getting a few people that don't want to over-torque the long bolts and/or crush or bend the side plates. They are made with one side bent out to start with so it goes into place easier. They are made to bend back in (and further) to match the frame pads. Make sure you got those long bolts SUPER tight (like 40-60 ft.lbs. with oil), and don't worry about how they look or distort. The side plates become attached to the frame, and the main base plate of the mm's is attached to the block, and the poly is between them to isolate and dampen the vibrations. If the sides are not tight against the frame pads, then it rattles like crazy & causes false knock VERY easily.

If that doesn't do it, then you should look for things touching like the downpipe to the frame & stuff like that. Could be just about anything else, but if the long bolts are super tight, it won't be the mounts doing it.
Hope that helps!
