Argh The prince of darkness strikes again !!!

I ended up going through the electrics and cleaning every connector then reseating and replacing all the bullet joiners, after experiencing one failure after another

These Lucas connectors especially the bullets seem to corrode after many years and hence are ticking time bombs

Don't you mean these Ripaults connectors? Once again Lucas being unfairly blamed.

Yes those darn things !!

i always thought they to were lucas mfr'd , clearly not,

Ive learnt something new

The relay was definitely Lucas.

Not really moaning as 46 years use isn’t bad

Can’t see a modern ECU lasting that long !

After replacing the chrome air filter for the original and fitting

Petronix coil & electronic points I headed back to the rolling road @

Rawspeed , Plymouth.

Last year we had around 205bhp at the wheels and it left yesterday fhe same.

Interestingly I arrived with 185bhp. The original filter is 10bhp down on chrome one.

The timing ended up around 12deg TDC with 24deg of advance.

Curve is a lot smoother on fhe Dyno at higher revs.

Also had a chance to paint the carport.

Ditto Gary's comment, all that hard work is now showing it was worth it.

John that’s fantastic, great effort. You must be well chuffed

I've had a weep on at least one of the gearbox cooler pipes for some time and after recently painting the driveway it was obviously getting worse.

After talking to Mark Rivron I realised he had a spare remote cooler so yesterday it was fitted.

I believe the same was used by Mark on CEA 1J & VRL563H.

Pleased with the install and no more topping up the ATF...

After around 8 1/2 years ownership I had my first 'fail to proceed' a few weeks back.

Heading to Torquay for a jolly with another Jensenite when 1 mile from his home I had the sight

of steam/smoke oozing out of my semi-louvred bonnet!

Managed to get to his home and promptly pull the bonnet catch.

A small jet of water was squirting out the back of the thermostat housing onto the engine block.

Dissapointingly the housing & gasket were less than two years old. After cooling down and heading back

home , a journey of 7 miles I headed to my mechanic.

The housing wasn't at all flat and the 'slack' had been taken up by the gasket. What was really bad was the

replacement was no better! It seems many parts are obviously made in the far east and it shows.

Both housings rock on their low points which is where the two bolts go through.

Thanks to DBC Garage as usual for sorting the issue out and getting plenty of water and antifreeze in

the block before the weather turns real cold.

I'm not a fan of these chromed thermostat housings.
My original had very badly corroded (see here: https://www.joc.org.uk/forum/viewtopic.php?f=4&t=23344" onclick="window.open(this.href);return false;) so I fitted a new one which was one of these chromed ones just before going to Italy in 2016 and just about 120 miles into the trip it started leaking. Some silicone sealant cured the problem but after getting back I replaced it with a NOS original that I found on ebay in the US and it hasn't leaked since. Interesting to see the last comment on my thread though!

I had a similar experience with a leaking joint on a new Summit chrome housing on my recent journey to the Swiss weekend which was cured by fitting a rubber o ring type gasket around the thermostat itself rather than a gasket between the two uneven surfaces.
