Things I want to Buy / JP2 injector pipes

I'm looking for replacement injector pipes for a JP2.  Anyone know of a source for these?
Many thanks.

Engines / JP2 big end bolts
« on: March 08, 2022, 05:35:21 PM »
I'm rebuilding an early (32/33) JP2 and hope someone can advise on big end bolt tightness.  Having tightened according to the book and loosened the two bolts by one half turn they are now loose!  This surely cannot be right?  All other engines I have worked on all bolts are torqued equally.

Another query - the piston scraper ring is narrow and unslotted but tapered on one side. Is it taper up or down?
Many thanks

Original Lister Cs Engines / Early JP2 loco engine
« on: March 10, 2017, 12:27:39 PM »
Any info please on an early (1931?) JP2 engine.  The cylinder heads are machined with an annular ring which locates over the liner rim.
They are sealed with plain copper rings and shims to adjust bumping clearance.  Water jacket sealed with rubber gromets.
Will the bumping clearance be the same as for later flat head types?
This engine is fitted into a Ruston narrowgauge loco but is definately Lister and not Ruston.
Any info would be welcome!
