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 past month.

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 problem.

Answer : 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 Britain.

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.
