I'm guessing you'll be needing a sealant that's flexible and actually sticks things together (not like the usual silicon gasket stuff, which doesn't really glue anything together, just fills holes).

Genuine Ford and Vauxhall sealant are good, and reasonably cheap (Ford stuff comes in a handy little dispenser tube, whereas Vauxhall comes in a short mastic tube and needs a mastic gun). Failing that, Tigerseal is always good, but may make future dismantling a bit more challenging!

Tigerseal is just a brand name for PU (Polyurethane) adhesive, and is used in the motor industry for sealing/sticking car panels on. It relies on moisture to set, and once set nothing other than physically cutting it of will shift it. Just make sure you wear gloves when dealing with it, as if you let it set on your skin, it takes a good few days for it to eventually fall off.

And no tat's here, only stubble!

I don't have a problem with dismantling it! I have all the tools needed to split them.

I genuinely couldn't get the cylinder off though.

on my 2nd day of riding the bike, I went to my metal shop to price up some alu for my cnc, went there today and said it was broken. he genuinely looked sad and gave me some steel and bolts for free.

he just told me to get the bike running!

I drilled holes for the cylinder studds in the metal and drilled a central hole. I had a 100mm bolt to push down on the piston and pull up the cylinder.

marked the piston badly but it was scrap anyway.

thinking about it, i should have picked up some alu at the same time and started to build my CNC on the cheap!

Sticky is ok, It has to be strong mainly. it needs to withstand oil, coolant and high pressures from the bottom end.
