With the scuttle on, you can't hear the noise  :-/

That made me concerned all the way home, as that was what I was going to be listening for.

Took it easy - 70-80mph - all the way, but the A43 got boring ::).  Didn't go mad, but it did cruise up to above 3k rpm.

Just put out the 2nd light on the LPG gauge as I pulled up.  40miles calibrating, and 140m home.

Sounds about right ;)

Did think it would sound much quieter with the scuttle on.

Any lag/hesitation on the LPG front?

[edit]Just seen your next post ::)

I think I'll be dropping the pressure on mine again and experimenting some more :-/[/edit]
Lag - impossible to tell, as I was being a good boy - for 130m, didn't go about 3k rpm, and at no point was it floored.

In all seriousness, it was one of those dreadful coincidences that would probably have been one of the first things checked if the LPG work hadn't been done :y :y

Definitely seems to be related to oil temperature (and thus pressure) :-/

Have you got an oil pressure tester Mr DTM?  :y

Fascinating thread.

Next suspect is oil pressure relief valve sticking? Or have I missed the point somewhere?

Yep... Could be other things too but definitely seems to be a pressure issue when the oil is hot (and thinner)

Fine under gentle driving conditions but not happy when driven hard for a sustained period ::)

[edit]Should add... Was suspect when the car was collected from MDTM :y[/edit]

Is there any other way?

The noise can't be heard in the car with scuttle on, but I'm sure I would have noticed it before with bonnet up, and Kevin Wood would have noticed when I drove into his garage.

I still don't believe in coincidence  :-/

I must confess, it's still hard to accept. But as we said, if you hadn't done any work you'd have looked at lifters much earlier in the diagnosis.

Just hope that it's fairly simple to put right.

I think checking the oil pressure is the next move - before it's driven hard, just in case.

To that end, if the thread's the same, you are welcome to borrow the pressure gauge off the Westfield for a while? Just thinking it can be chucked on top of the dash so you can keep an eye on it while driving.
