ok so i been searching the boards and various others and best i could come up with is a stuck lifter or flexplate.
let me explain what happened. I was driving normally and all was fine. i needed to get over to make a turn and had to floor it to get around a slow poke. when it downshifted and the rpms went up it instantly started knocking. it is a good healthy metal on metal knock. doesn't sound like the low end but its hard to tell. i checked and tightened the flexplate bolts. i started the xj while i was under it and you can clearly hear the knock is above. sounds like the back of the head. I took the VC off and all pushrods were tight and everything, although quite sludgy but typical 180,000mi, looked and felt fine. even had a mechanic friend come over while i had it off and he said he thought it was the flex plate. i don't know what to do next and it suck cuz this is my only car. i took the last couple days off work to try to fix it and nothing is working.
any insight or anything would be greatly appreciated
