Thanks

Mr Haynes suggests the conrods can be reomoved with the engine in situ ...... :-/ :-/ :-/ :-/ never done or seen it done though. :-/
-
AFIAC the conrods can stay if - if the shells can be changed - if the noise is bottom end that is

That's what I meant, if you can remove conrods, they have to unbolted so that'd mean shells could be changed.
What makes you think the bearings are shot? :-/

Support engine from above, sumps off, baffle out, pickup off.....and away you go

You mean the main ally sump?

You were looking forward to doing that on mine - is that why you knew :P
-
Aghhhh!
Quiet all the way to work.
Stuck in R and it started.
Parked up still going.
Lifted the bonnet and the mechanics over the road had a listen under bonnet.
That sounds fine - no knocking noise ::) ::) ::) ::)
-

Maybe it's a transmission issue?
Kevin
-
If its a knocking in drive .. perhaps its the rubber bushes for the drive shaft allowing too much movement ??
-
Its not the iron vibrating on that ironing board someone has bolted to the boot is it?
-
Really doesn't sound like big ends to me if the noise is coming and going. Would expect big end noise to be based on load, and always there, or at least there once the oil is hot.
Worth checking the torque converter to driveplate bolts are tight, and all present?

Stop scaring me :o
-
It is hot when noisy and not under the bonnet, almost like something was hitting the body.
Does it when stationary as well.
Might record it later
-
Is the engine moving at all ?? could be a worn engine mount ??
Loose exhaust bracket/hanger ??
Engines tend to "rock" more at idle than at higher RPM ... if something is slightly loose it could cause contact ?????
-
Don't discount a knackered ancillary too. Does it do it with aux. belt removed?
Is the starter motor (and all other ancillaries) mounted securely and not working loose?
Kevin
-
I have recently changed the engine mounts and still I can feel the play with some lever (though not easy to position ) ..
check them..
-
getting back to the "exam question" - you also have to drop the front crossmember.
not actually all that difficult a job.

Why?
Subframe I can understand but, the front cross member?

might sound daft but ive had a knocing noise on mine turns out its the end of the aircon pump worth a look
-
I'm going to wait and see, if they need changing I am not sure what to do, as I go off on holiday before too long.

Mine is idle only when been running for at least 15 minutes and cannot hear under bonnet
-
I am going to just see what happens I might need a JV6 or DLK as I don't have long until I disappear, and I have to get the caravan sorted first.
It does sound really worrying though - I will record it tomorrow and upload.
Aux belt off engine needs to be hot and it is difficult to get the belt off with plenum on.
-
Aircon pump would not be too bad.
At traffic lights it did it up to about 2000 rpm when engine noise meant I couldn't hear it.
Under load, no noise, road noise covers it as well.
It first happened after trying to work out why the 0305 was happening, I drove at 6500rpm in first for about 20 seconds with little load, would that have caused any issues?

I got TheBoy's aux belt off and back on again with plenum and multirams in place. :y
It must be worth a try just to eliminate the ancillaries, surely?
No problem with it being hot. You only have to run it for 30 seconds and not under load. It'd almost cool by convection.

I recently managed to remove mine with everything in place. But had to admit defeat putting the new one on, I ended up with a cat's cradle of fan belt, & took the bag pipes off before I blew a gasket. ;D

Admittedly it's easier if you're putting the same one back on. ;D

Ah! That's easy ;D. I thought you meant removing to replace the belt. :y

we mean the same thing. The frame underneath that the engine mounts and the wishbones bolt to. The thing the Yanks call the K-member.
-
Piston slap due to overfuelling?

tis indeed easy, re greased my tensioner pulley, removed nothing bar the belt and pulley itself.
-
Not borewash, is intermittant, so not big ends, possibly a lifter

A lifter would be very obvious from under the bonnet though. :-/

Had a little just after startup then quiet, nothing else
Changed the tensioner pulley today, so will what happens on the way home

yep..mechanics use that one :y

Big ends have a noise of their own, you can tell, that low rumbling noise. In my experience they go just has you hit the red-line when in 4th gear with overdrive on, that was in a Humber Sceptre many years ago, easy to fix though..... :y
iirc Triumph Spitfires were an easy engine to knock them out on...... :D :D :D
I have never heard of a modern car needing the big ends doing... ::) ::) ::)
Hope you get it sorted before you need to tow your caravan..... :y

Was quiet on hte way home tonight :-? :-?
