Name that noise!

OK! i've asked about this before. i've had lots of possibilities. and i'm getting annoyed! please please PLEASE! someone help! here is the story:

looks like a bloody menu ... maybe a video with the noise on would be a good idea

Have you checked servo pump, can make knock but not connected to water prob.

Are you sure its coming from the engine and not a wheel (cv joint etc)?? as its in time with road speed.

its the engine. its there when the engine fires up. on idle it clunks at idle speed.
the sound is coming from the engine block. cant pin it down to a location as its so bloody loud my ears cant handle it!

think massey furguson tractor loud!

Big End Bearing??

the head gasket is proably blowing between cylinders and only just to a water way

well, im hoping it is the head gasket! as odd as that sounds! ive not done many miles since it started (3 at the most, and over 6week period) so shouldnt be any damage other than the gasket. ive just ordered a new gasket and head bolts...etc. but need more suggestions..... is it completly FUBAR?

anything like this? [nomedia="http://www.youtube.com/watch?v=sgtV9H18EwE"]YouTube - TDi Problems - Feb 08[/nomedia]

YES! YES! YES! thats exactly it! PLEASE tell me its good?

well according to that article it was a broken crankshaft bearing which means a bottom end overhaul i guess. Also according to them you should have low pressure on one of the cylinders which will tell you what one is broken

OUCH! well. thank's very much. it's been such a pain. so many possibilities. glad i know what to check next.

could be worse could sound like mine lol.

Sounds the same, to me, plus a bit of exhaust manifold leak

that is cam speed,could be push rod bent or pushed thru follower broken tappet ,or valve stem cap ,take rocker box cover of and turn over and check

sounds like one a saw with broken valve spring, from there you dont want to know. Worth lifting rocker cover to have a look.

mine was a result of a screwdriver bit ending up in no.3 piston lol. All sorted now thou. Replacement engine, as it worked out cheaper. The vid of mine that i posted, was after i removed the bit. Was running with a bent no.3 inlet vavle, and a slight exhaust manifold leak.

DORA. she live's. it's been a while, but i've moved home, fixed the mysterious noise and for those who are interested. it was a simple fix. INJECTOR WASHER/SEALS. over looked many times. now she's purrs like a 2.25tonne kitten!

Hi ibought a disco with with that noise and the guy knocked £500 off the asking price so i could buy a new engine. Well its still running 3 years later with the same engine ...all i do is give it a oil and filter change every six months ......
