Puglet1 Posted October 1 Report Share Posted October 1 Hello All. An unusual engine noise started yesterday after driving the car for about five miles. It appears on idle and not when rpm is increased. It remains whether the clutch is dipped or not. I have removed the fan belt but it makes no difference. Its difficult to tell whether it’s from the front or rear of the engine but from the underside of the car it sounds more like it could be from the front. I have recorded the noise hoping that one of you experienced guys might be able to help. Hopefully, the video is attached.

johny Posted October 1 Report Share Posted October 1 really does sound like a rotating element noise but I cant think what! However as a separate issue is the exhaust blowing somewhere as I think I can also hear the phutt, phutt of a leak? Link to comment Share on other sites More sharing options...
johny Posted October 1 Report Share Posted October 1 Any vibration you can feel round the engine, without getting burnt, that matches the generation of the noise? Link to comment Share on other sites More sharing options...
Puglet1 Posted October 1 Author Report Share Posted October 1 Hi johny - you have good hearing, there is an exhaust blow from the manifold- which I plan to do when I replace the cylinder head. Can’t feel any vibration at the moment. Link to comment Share on other sites More sharing options...
dannyb Posted October 1 Report Share Posted October 1 I'd say timing chain and or tensioner. Sounded a bit like my spit a couple of weeks ago until I changed the worn chain. Danny Link to comment Share on other sites More sharing options...

johny Posted October 1 Report Share Posted October 1 Get the big ol screwdriver out and have a CAREFUL listen round the engine including cam chain box - probably need an assistant to rev it a little.... 1 Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 1 Report Share Posted October 1 if it had the belt fitted i would plump for water pump gland but its not that cant seehear any connection with timming chain . i would have alook inside the rocker cover zone and the smith s valve diaphragm Pete Link to comment Share on other sites More sharing options...
trigolf Posted October 1 Report Share Posted October 1 Have you tried to locate the noise with a DIY ' stethoscope' i.e. a long screwdriver held to your ear? A 'strikethro' screwdriver works even better at transmitting the noise. Link to comment Share on other sites More sharing options...

Pete Lewis Posted October 1 Report Share Posted October 1 do take care or you can end up in A &E to get it removed Pete Link to comment Share on other sites More sharing options...
trigolf Posted October 1 Report Share Posted October 1 Pete's caution is very valid! The sound does seem to sound like a rotating noise? Probably a very long shot - but could it be the crank pulley???🤔 1 Link to comment Share on other sites More sharing options...

Coincidentally, when I first start the engine it sounds like x1 tappet is noisy, I wonder if I have oil starvation somewhere? Link to comment Share on other sites More sharing options...

Iain T Posted October 1 Report Share Posted October 1 Take the rocker cover off, at tickover there should be a slow drip of oil from each rocker arm. Iain 1 Link to comment Share on other sites More sharing options...
