Hi Guys,
I'm Gary from Victoria Australia. It's my first post here so here goes....
a few weeks ago while driving home from work my 06 JK's engine suddenly died. It gave a faint knock before I shut it off and rolled to a stop, suspecting a broken timing chain, I then had it towed home.
I've finally got around to pulling the valve covers today and too my surprise I found 3 rockers were loose in the head, 2 on the right and 1 on the left.
What would cause this? It was I very hot afternoon (40°c or 104°f) but it wasn't running hot.
The oil was down a bit but nothing concerning.
Would a sudden lack of oil pressure let the lifter thingys pump down and give the arms enough slack to pop out?
Thanks for any advice in advance.
Cheers.
