OK my car is off the road at the mo as I am doing some extensive mods on the body. I start it more or less 3 times a week and let it run for around 20-30 mins. The car has always had a slight tapping deffo from the top end for about 2-3 seconds on starting ever since I have had it. now though it seems to keep tapping until I rev it and then it stops. BUT! after letting it rest on tick over it starts to tap again. the noise isnt very loud and as I said as soon as I rev it to anything above tick over it stops? I know this could be one of many things but what do the experts think? PLEASE. ( the noise could also be described as a loud tick or quiet tap. :D or somewhere in between???)

 

There are no other noises and the engine still runs very nicely. Its only done 54,000 Km's.

 

Thanks vince

sounds like a sticky lifter matey.

Mine does this vinny after its been stood for a while. Let it warm up, take it out on a road and give it a good thrashing. :D

 

Usually goes away when used on the road.

Yeah, a sticky lifter, you could try an oil change with a good quality oil. I had a similar problem with mine although not as bad as yours and now its quiet from start up! Do a search for recommended oils theres quite a few threads.

Thanks chaps.

 

The chance would be a fine thing Pete. Its lacking a rear bumper and the front is held on by only two bolts at the mo. Its on SORN and has no MOT. so I will have to wait. :D

I wouldnt worry until you get it back onto the road. I do exactly what you are doing over winter and its still tappy when i start it. as soon as i start using it on the road again it disappears.

Once its ready for the road I will get the oil changed it had new oil in it last year and only done about 700 miles but I will change it when Its road worthy. Thanks mate.

Sticking lifter - if your just starting the engine and letting it idle then your not getting full oil pressure up to the lifters - it needs a good drive to get oil back up

oil pressure is at its highest when cold,and a brief tap is fine,as its just the oil working its way around the lifters,best bit of advice is get a quality exhaust systym,with wide straight through pipes,you wont hear a tap again :D

Oil pressure is higest becuase oil is thicker but do'snt penetrate Lifter oilways as it would when hot, you also get a build up of crud in there as well over a period of time which can cause a sticking lifter, usually cleared with a good flush and change of oil.

Good Idea Greg mate. the only thing is I would have to get a louder wireless as well???? :rofl: the old ones are best.

can anyone tell what is normal oil pressure when idle? thank you

when hot between 10 and 20psi
