Idle Noise

[Fiddescs]

Hi,

I have recently noticed a noise upon idle and best way I can describe it is a sloshing sound!  It is not a grinding, scraping or alarming noise nor is it apparent in the engine bay…only when sitting in drivers seat.

I am thinking it might be the oil flowing from oil tank to oil cooler and back.

Would this be a potential explanation?

Anyone experienced anything similar?

thanks

Will hazard a guess at the oil filter.

My 86 car used to do the same, I never got to the bottom of it!

I think your right in saying it could be the oil flowing through the oil cooler pipes, I am sure I had the same noise on my 1981 SC.

I do remember a thread on here somewhere about a specific brand of oil filter being 'noisy'. May be worth a search if you haven't already.

Thanks for all the replies.

I will change the oil and oil filter as the latter is due a change anyway - see if it has been causing the noise.  I won’t open the debate on what oil to use/is recommended and will stick with my preferred brand and viscosity!  While it is relatively fresh oil (under 1,000 miles) I suspect it might be a cocktail of brands and viscosity which may not be helping matters.

I did notice that one of the oil pipes was slightly dented but is only ever so slight and not crushed.  I doubt the size of the dent could be culprit.  I will however do a comprehensive check along full length of pipe just incase.

I tried to take a video/sound clip but it is not noticeable.  I will try and again and see if I can capture the noise.

thanks again
