My next project "La Petite Chanteuse"

3 minute(s) of a 82 minute read

Another day and another box ticked.

Less than three hours after the Post-man delivered the goods the Lagonda Rapier's exhaust headers are back in place with the new flange gaskets, BSF Studs and correct 5/16 BSF brass "manifold nuts"all in place. I will run the motor tomorrow to warm it all up then re torque the nuts. Hopefully this will put an end to the leaks from a couple of flanges.

BSF Studs and correct 5/16 BSF brass "manifold nuts"

Some of you may be questioning my sanity or wondering what is special or different about the nuts that are used to secure the exhaust manifold. Apart from being brass so that they will not "rust on" or become seized onto the thread due to the frequent heating and cooling, "manifold" nuts are approximately 50% longer than a standard nut. Again in the words of my favourite old song, "little things mean a lot". Being 5/16 diam, 22 tpi these are torqued up to 10-12 ft/lb.

A quick course in applied physics.

While I had the exhaust headers off the Lagonda I decided to give them a fresh coat of paint. The only 'high temp' paint I had handy was matt black so naturally I used this. On Sunday we were out in the car and got caught up in some heavy (stop-start) traffic. My wife Helen commented that the passenger (exhaust) side foot-well seemed much warmer than usual. So todays task is to remove the exhaust again and repaint it silver.

For all those people who have not looked at my previous posts and not have seen a Lagonda Rapier before and I know how much many others enjoy looking at photographs, below is a photograph taken as recently as Sunday morning at the Start of the VSCC of Aust "Inner Urban" Sunday morning run. A good chance to check out the cooling system as this is predominantly run through busy "Pre-christmas" traffic with long delays experienced getting from Point A to Point B across one of the city's popular bayside centres. For comparison purposes it is seen here in company with a SS 100. The event starts from one of Melbourne's many extensive & beautiful parks
