My 4L pushrod Ex, makes a noise like high presure air leaking through a blown joint, this happens as the engine gets hot, say if standing in traffic, only at tick over, goes as you rev the engine. The AC leaks a little through the pump body, but filling once a year with a can and gauge its Ok so don't think its that.the belt does not appear to slip. I thought it may be the cooling fan viscous thinging but dowsing it in WD40 makes no difference. Any ideas

I had an "air noise" that I finally figured out was due to the air filter not being seated properly in the container. The oil change folks had pulled it to tell me I needed a new one. Took me a while to put the two issues together.
