occasional clicking noise is the chain slapping or a sticking valve all the valves and guides

Hello Wayne, thanks for your answer. The engine was fitted with the 3.2 Carrera pressure tensioners about 80000 miles ago, they have been put back into the professionally rebuilt engine. We are not sure if the occasional clicking noise is the chain slapping or a sticking valve all the valves and guides were replaced at the rebuild The worry is that the noise only occurs during tick over when the oil pressure is low. I was told by the rebuilder that you had a oil flow restricter that could be placed in the oil pipe between the tensioner oil take-off pipe and the supply to the camshaft. These are only holes in the supply pipe supplying oil to the camshaft lobes, and may be the reason for the low oil pressure at tick-over. Do the restricters exist? and can you supply them? Robin.

If you are concerned about oil pressure, I would put a gauge on the engine and check that it is in spec. I am familiar with an oil tank breathe restrictor, but not the one you are describing.

I opened a post in our forums. A Pelican community member may be able to answer your question.

Robin,

Those chain tensioners shown in the picture are not the 'hydraulic fed type' tensioners. Look very closely and they seem to be similar to mechanical (adjustable) tensioners people use in race engines. Keep us posted.
