Why do the French use so much loctite on various engine nuts and bolts?

Was undoing this one yesterday on a 406 DW10 TD for a cambelt change and the ******* thing snapped!

Fortunately, we have a little jig/mandrel and cobalt drills to drill out the broken section and retap the thread, worked a treat but sure had me worried for a couple of hours.....

seen it done on a Rover many times, although not snapping the bolt but stripping the thread completely both on the bolt and the hole it came out of.

Rigid plastic John Guest Speedfit compressed air pipe - running at 150psi - it's good kit.

150 PSI!!!

At work we only run 80 PSI.

We use mainly Nylon at work, its pretty rigid, and a right git to work with coz it likes nothing more to coil off, then unravel properly.

For panel building we use a very flexible pipe, not really anygood if its unprotected, but in SS panels its excellent.

We are now beginning to start using pushfits a bit more, copper fittings are still preferred though, using proper olives, so they dont just cut through the pipe.

At the moment, a large air main is being run in our new workshop, using 25mm conduit with top facing outlets after every 3 meter length!!!

I should run a pressure regulator (I will get one, promise!) but I'm just using tank pressure......right out of the tank.


Got a speed/torque control on the gun, so it's no problem when I need to tone it down a little.

A regulator is the easiest/safest way to tone it down.

How do you get rid of moisture, is it all handled by the compressor??

did you try running that bolt out with an air gun straight away or did you start it with a ratcher/breaker bar?

Cheers

Polyethylene (PE) then. Good stuff, this is what Transco use for gas pipes. Fecking good stuff!

Nope....all the way out with a gun, done it hundreds of times before with no problems.

Next time I would do it with a HOT engine, I think this would loosen the loctite somewhat.

It's happened to others before, I'm sure it'll happen again one day!
