Tackling 'tappet' noise
Question : THE tappets on my 1980 Mark 2
Ford Escort 1.3GT have become
increasingly noisy even though I've
had them adjusted twice in the
I have tried adjusting the tappets, both when the engine is
warm and when cold, but to no
avail. The engine runs noisily even
after it has warmed up.
My mechanic says that a worn
camshaft is the cause but spares
are no longer available.
I would appreciate your advice
on what else I could do to solve my
YOUR mechanic is correct in saying
that a worn camshaft would result in
a "tappetty" engine. Then again,
worn cam followers, rocker shafts
and tappets (rockers) would also
result in similar noises, and consequently noisy engine operation.
The only way you can really tell which is the cause is by dismantling the
engine and examining each component for signs of wear.
Worn rocker shafts, cam followers and tappets must be replaced but camshafts
may be re-profiled by a camshaft specialist. Such specialists who will be familiar with your
car can be found in Australia or
A new camshaft may be purchased on an exchange basis or, alternatively, your current camshaft reground
to a new profile.
There is a good possibility that the
camshaft specialists may also be able
to supply the replacement valve train
components that you require.
