I think I figured out what your talking about now on this. We've just never seen it get that bad. We've seen the valve stem stem pounding thru the cam follower. But that makes a lot of noise, I wonder how long you have to go with that thing clacking to get to where that shitbox is at.
It pisses me off that they built this special engine for Rover if they had juist used the already proven coyote this would have been a spectacular vintage of Rover
I was thinking about what you said about the keeper moving down the shaft of the valve. That kind of explains the whole thing. If the keeper was moving down the valve stem and the valve was sticking up higher than the spring retainer. it could explain the whole pushing the valve thru the cam follower. Like you said it doesn't happen often, but now I think I understand that whole failure a little better. Thanks for that.I think if the spacer in the bucket is pounding through the keeper has already started to move or the clearance was way off
This engine came out in 2010 model year. When did they make the coyote engine?If my engine ever blows up I'd coyote swap the truck. It'll probably bolt right in.

So the coyote does all that on regular old port injection? As apposed to direct injection?
For 2018, Ford made revisions to the Coyote equipped in the Mustang GT, most notably the addition of high-pressure direct injection (in addition to the existing port injection system), and an increase of the piston bore diameter from 92.2 to 93 mm (3.63 to 3.66 in). This increase in the bore size, resulting from the adoption of Plasma Wire Arc Transfer cylinder liner technology in place of the more traditional sleeve in the block, brings total displacement up from 4,951 to 5,035 cc (302 to 307 cu in). Other changes include Gen. 3 specific camshafts, enlarged intake and exhaust valves, an increased compression ratio of 12.0:1, a revised intake manifold, and 7500 RPM redline in the Mustang. With these changes the updated 5.0L Coyote is rated by Ford at 460 hp (343 kW) and 420 lb⋅ft (569 N⋅m).
It's also got an ECM for each bank. I wonder why they did that?
