Camshafts


Tapping, ticking noise from top of engine? Signs of an oil leak resulting in excessive usage?

This could be your vehicles camshaft worn or camshaft oil seal leaking. Pentagon Motorist Centre Chatham in the centre of Medway can diagnose and repair these types of faults

What is a Camshaft?

A camshaft is a part of an internal combustion engine. It is a cylindrical rod running the length of the cylinder head which has a number of oblong lobes protruding from it. The camshaft is used to operate poppet valves; there is one cam lobe for each valve. The cam lobes force the valves open by pressing on the valve as the camshaft rotates.

Timing:

The relationship between the rotation of the camshaft and the rotation of the crankshaft is of critical importance. The valves must be opened and closed at the appropriate time during the stroke of the piston. This opening and closing of the valves, if not synchronised exactly, can cause a ticking or tapping noise from the top of the engine. The engine will not run efficiently and there could be a lack of power. In extreme circumstances a badly timed camshaft may cause irreparable damage.

The camshaft is retained into the cylinder head and is lubricated with the engine oil so that it does not become worn. Each valve has its own individual oil seal as well as the camshaft at the pulley end. Over time these oil seals can become worn and eventually leak and cause excessive oil loss.

Why Choose Pentagon?

On many occasions when carrying out a diagnosis a partial strip down is necessary. Should you agree to have any necessary work completed at this time, this initial diagnosis becomes free due to the fact that your vehicle has been partially stripped down already.
We at Pentagon Motorist Centre in Medway have established a superb reputation for high quality vehicle repair services, refer to our testimonials from our customers from Chatham, Gillingham and Rochester on our testimonial page.

If your car has regular oil loss then regular checks should be carried out at least on a weekly basis. Low oil level will cause your cars engine to become even more worn. It could even begin to make a tapping or ticking noise from the top of the engine. If your engine is leaking oil then book your car in with Pentagon Motorist Centre in Chatham we are close to both Gillingham and Rochester in Medway.
