Has anyone ever removed the oil filler cap with the engine running? took mine off tonight and got the shock of my life . Loud clattering noise, didn't sound at all well but with the cap on all quiet again!!

Has anyone else heard this??

I wouldn't be surprised since I should be a pretty straight run into the bowels of the engine. Ed

oh yes, straight onto timing chain. Just a bit alarming to hear it

Why did you take it off?

(PS a Scimitar GTE is my joint second favorite car of all time - jointly with the GTC)  405 AB exec seats Baltic and Cirrus
93 RR Classic efi

Remember it's easier to get forgiveness than permission!

Gone in order:
4.4 TDV8 SE - gone to a good home
93 Classic hard dash Plymouth Blue
03 L322 Oslo Blue
2000 Disco TD5 ES Epsom Green
98 P38 Rioja Red
89 Classic Cairngorm Brown

What did you think you would find or hear ?

It's a massive 4.4 V8 diesel engine with 2 Turbo's, timing chain and 16 valves going up and down thousands of times every minute - right inside the valve cover - it's not a euro box with a tiny 1.1 engine You were lucky you didn't get covered in oil. relax the racket is normal - even a small amount of smoke from a tiny bit of blowback coming out of the oil filler is also normal.

You should hear a large tractor or truck engine close up  2021 L405 Vogue SE 4.4 V8 DIESEL ~ #17

Need to update my sig line, the GTE went a couple of years ago, to be replaced with a TVR chimaera, then a sierra cosworth, then a porsche 911, then an Audi RS6

Needless to say i get bored quickly

PS Vogue, i worked on trucks for over 15 years but have never heard such a well insulated oil filler cap as on the 4.4 tdv8  Paul
