300 tdi auto 97 with trickery,
right then this motor as a tap/knock from fek nows were had lots of o ya thats the fuel lift pump nope not that /no its the vac/pump not that ever.
tappets etc etc ..this is from local garages please note not from this forum have had these things suggested on here but as said these garages were listening to the engine running but they all said they would book it in to do. price how longs a bit of

so rebuild or
second hand unit
price to rebuild ?
price to get s/hand engine and fit
have got most tools but no engine lift

stick a long handled screwdriver to the engine and rest yer ear on the handle. It will act like a stethescope.

If it's more of a loud metalic clack my bet is it's coming from number 4 cylinder.

has the vehicle been overheated or run low on oil? how long have you owned it?

pete@her · Feb 14, 2010

i have tried this,and many others but no one seems to find were its coming from,
you did reply on last post and i did try it then.
i have done over 1000 miles with this tapping but am now losing power and a bitch to start.
f/prop fell off last week so now's the time to do all the jobs in one go.
anyway no over heating / no lose of oil.
but it was run on bio for 18mts before i got it.
some one suggested inj pump /piston slap/cam-followers/ends/vac-pump/fuel-pump/w-pump/piston hitting head
so i think trip it and see wile iv got other transport

any blue/grey smoke on start up and for the first couple of minutes of driving?

GRATCH · Feb 14, 2010

test yer injectors.

pete@her · Feb 15, 2010

yes plenty off smoke blue black and turns over for ever before fireing but if i use e-start it fires up with no smoke at all and first turn of key.
injectors? will that make it tap , i have undone inj with engine running this made no difference to tapping.
dont want to strip engine for nowt.

sounds like your glowplugs ain't working,to start it

pete@her · Feb 15, 2010

your right about glow plugs they dont even get warm.

so the injectors do they just pull out once you undo the nut and keeper plate?
and if there ****ed would this make a tapping noise.

Sean · Feb 15, 2010

hard to diagnose sounds over the web, but if you've been thinking tappets (and it wasn't) you might care to change the injector sealing washers
