I was going for a flight in a helicopter in the States. I asked the owners wife if she flew a helicopter. She said son, I can't walk down the street and chew gum at the same time!

It’s derived from Romani Gypsy, “murdered”. East London used to be home to many a Romani Gypsy, quite a few interesting words. I like knackered as well, derived from “knacker” a person who used to slaughter horses. “Mullered” beats “Knackered”for severity, although they do mean different things really.

@@HuntsChris thank you very much for the reply and the information. I appreciate your time and effort.

@@HuntsChris knackered means ready for the knackerman, basically worn out, broken.

@@HuntsChrisvalid explanation definately- but recall from my linguistic anthropology days the words were also argued to originate slightly differently. ‘Mullered’ was thought to hail from the East Counties of England - primarily flour producing regions. To ‘mull’ something was to pulverise by grinding ie the flour mill stone. ‘Mullered’ being the complete destruction of something. ‘Knackered’ is by way of agreement, related to the equine industry. But some believe the regional origin of it to come from the Northern Counties of England. A knacker was traditionally employed to remove the danglies from unruly or aggressive Stallions. Hence some people referring to testicles as ‘knackers’ - again a more commonly used term in the North of England than South. But both are valid origins of the words - not disagreeing with you just a different viewpoint lol.

There are different types of silicone. Maybe this one they used the wrong type?

You may not have but its not to say it isn't happening.

I use Dirko HT silicone made by Elring on engines, gearboxes and transmissions that i repair and re build, it never comes off inside an engine unlike bathroom silicone which i have seen used by clowns in engine rebuilds.

Good shout that is, but I think he gave the head a lick, so they should all need something off

Have to agree John

Seems to be a good 50% of their work! Good reputation for doing cosworth!

Lee has featured Triumph Twins before. The man is an ex-Superbike racing mechanic.

The camshafts are no different from a 2 valve per cylinder cam shaft except they have extra cam lobes, a 20 valve four cylinder with rocker arm set up is a bit more complex looking but its still simple except it is crammed into a smaller space

@@madeljacky I understand.Thanks.

Yamaha launched a bike with 5 valves per cylinder in about 1984. Aprilia launched an engine with a radial 5 valve head in the early 1990s - 4 valves opened directly with skew ground cams a one by a rocker.

Buckets are used on many overhead cam engines - e.g. VW, Alfa, etc. The bucket accommodates the valve stem and springs and provides a 'constrained' surface for the cam lobe to contact in order to push down (i.e. open) the valve.

Probably most of the classic twin cam engines, e.g. Alfa Romeo and Jaguar from the 1950s used bucket tappets, Fiat and Lotus in the 1960s, the Toyota 4A-GE twin cam in the 1980s and others. Quite a lot of SOHC engines used them, from the little Hillman Imp engine from the 1960s to the Jaguar XJS V12. Depending on where you are from, you might hear the phrase 'cam follower' or 'lifter' instead of 'tappet'.

@@georgebettiol8338 The Repco V8 GP engines (1966-68) used Alfa buckets.

It's a recall from bearing supplier. Probably waiting for replacements.

I couldn't hear it.
