How To: Restoration of Ford M8 armoured car US Ordnance number 7373

Hi David

Thanks for the reply. You might be right that it is air rather than mechanical. I'm pretty sure it has been there since day one and it seems to be more toward the co-driver side corner. It did sound a little like the sound you get from the top of the vacuum fuel pump before I plugged the output that would be for the window wipers. A sort of 'phit,phit....'

I've uploaded a short video clip. Not sure if that will help but you will probably get the idea:

Here's another longer video. I'll have a closer look in the other side of the engine bay when I get some time:

Hi Darryl, Have you checked your fanbelts for a hard/soft spot. Looking at your video the noise is in-time with a section of your fanbelt as it goes around. Cheers Rick.

Hi Tim,

That’s not what I wanted to hear! Haha.

How’s your restoration going?

Hi Rick

That’s actually a very good suggestion. I hadn’t even considered that. I will check that out ASAP.

I’m hoping to get the wheels off today as I get ready to replace all the wheel cylinder cups on the drivers side.

I looked at everything else first in the hope it wasnt. Can you do a compression test easily on your cylinders? Hopefully a fan issue as suggested by someone else.

The Firefly restoration is coming along nicely - thanks.

I expect to have it on the road for the 30 corps event in the Netherlands in September... though there is still a lot to do between now and then.

I had a similar sound on my white scout car... turned out to be a head gasket issue.
