Motorway speeds

Hey, nice inspection pit.

Lying on a cold concrete floor loses its attraction after the first twenty years...

Too right! That's why I have a creeper. It's very comfortable.

Hey, nice inspection pit.

It's o.k. but you need a good pump for when it rains

I wouldn't have needed a pump if the " builders" had followed my instructions with the visqueen , I later had to dig out a pump sump.....that's when the building inspector nearly closed the road and evacuated the street due to methane build-up.....that's when I had to install a gas scavenging system...

Just like working on a Lotus. One thing begets another.

So... I think it is definitely wind noise. I opened the window @ 70 MPH and the sound from the opening was exactly the same.

An update to an old thread.

This evening I finally took the car out with plastic sheet covering the intakes on the bonnet. There was still some wind noise at motorway speeds, but nothing out of the ordinary. So I have concluded that it is caused by the heater box after all and I should see some improvement when I finally overhaul it.

Of course, there are a whole raft of squeaks and rattles to be addressed, but those are another story.
