Knock Knock

[stroller]

hey, my ute has developed a knock.

its only worse at start up but it can still be heard all the time. doesnt change with revs much and doesnt change putting into reverse or drive. my old man whos a mechanic reckons cracked piston or bottom end gone, but im seriously hoping not.

any ideas?

If it does NOT change with rpm u USUALLY can rule out the rotating assembly etc etc

Video/Audio of knock ?

Here is a video. I'm pretty confident it's the flex plate come loose

A bit short, but could be the flexplate.

Speaking from my recent experience, it doesn't sound like the flex plate.

When my flex plate went the other week, it rattled like a *beep* at idle but went quiet at any revs over that or while there was load on it.

Cost you a bit under $1000 supply and fit at XFT for a Nizpro one.

Fairly quick job if they have one there.

But it was a tinny matallic type of rattle, that vid doesnt sound like it.

Sorry :(

Are the starter motor mounting bolts tight?

[stroller]

yeah starter motor is solid.

a friend of mine said it sounds exactly the same as his when his flex plate came loose.

it goes into ford on tuesday anyway, see what they make of it

[Boganspeed]

Good luck mate, hopefully that's what it is.

Not cheap, but not serious either.

You should consider an upgraded one with good bolts and loctite if it is.

This is what mine looked like, you can see the egged holes, and I caught this quickly.

There was no retightening this one and fitting another stock one would probably have led to the same failure again.
