Tapping metalic engine noise

Post by **iain** » 25 Jul 2006, 08:08

Engine 2.1 DF. Oil changed (and flushed 300 miles
ago)

I have read through the post previously on this but
would like to know some thoughts on my problem

Drove to cornwall 180 miles no problems. Next day
no problems on a short journey to beach. Second day
engine sounds like a bunch of spanners banging
around. Drove 1.5 miles to beach. My hearing may
not be the best but it sounds like it is coming from
near side of engine maybe cyclinder head, maybe
closer to crank case.The noise is very metalic. Have
taken the head covers off nil of note. The RAC have
just relayed me home.. with no advice and i need the
van very soon, inlaws need to be picked up from
airport. What do you r econ it is.. any advice on fault
finding. I have recorded the noise but have no clues
on how to post it.

Kindest reagrds

is it tappet noise?
are you familiar with the sound of tappets?
where are you?
fill in your profile, and maybe someone is close to you to come have a listen live?

i am not sure what the tappet noise sounds like

Dreadful, loud, like a metallic tapping, it'll probably go away after a few miles. Another description might be like a Mac trying to do a PC's work

What oil did you use?
Anything less than a 15w40 will make the tappets rattle.. a 1.5 mile drive wont help either..
A tappet that has bled a lot.. will make a hell of a racket!!

Oh 2.1 DF?? DJ more like, or its a 1.9... has it got Fi or a carb?

There's a tappety noise (1.9DG engine) in the wiki here.

Wasn't actually the tappet in the end, but it's the same noise!

I am sure it is a df (i presume that means digifant) it is a 2.1 whitestar, born feb 1990, import from germany. it has definatelly got injection rather than carb. I will ask the garage what oil they used to make sure its viscocity is correct.

If i do a trip will i ruin the engine, and how far should i drive?.. should i open up the clearence to try to purge the air?

Oh and shouldn't it be the noise a PC makes when trying to compete with a Mac... Mac's rule

Nope wont be a DF, it will either be a DJ or an MV (Could be an SS but not likely).. DF was a a low power 1.9.. MV/SS used digifant with lambda probe and cat.. IIRC. DJ used Digijet without lambda probe.

If it is the tappet then it will clear after a little run.. but it wont sound pleasant.. just dont thrash it.

if the engine is very healthy, then a 10w40 might be ok.. but VW always spec'd 15w40 as a min unless in cold climates, filling with a 20w50 will normally clear a rattly tappet on a tired engine!

Engine oil was 10/40 semi synthetic.
Is this an OK oil to use sorry i do not understand viscocities

the engine code is MV, sorry ithoughtDFrelated to the digifant system, which it has on it

10w 40 thinish
15w 40 thicker
20w 50 even thicker
that how the oil ratings work
