After having acertained with Steve that the former problem was indeed a pushrod that had come out of its cup during adjustment of the tappet clearances, and that no damage had been done, the new head gasket is in place and the cylinder head re-installed.
Cylinder head being lowered back into place:
Rockers cleaned up (and pushrods carefully checked!):
A new front right spring was installed, from Paddock's, as previously the Land Rover was leaning towards the left-hand side, when using two equal front springs. By using what is normally (on right-hand-drive Land Rovers) a front left-hand spring in this right-hand side, the vehicle now sits perfectly level. Thanks go to Lars for that tip.
After having the cylinder head off three times in the past couple of weeks, everything is now back in place. I ran the engine for 20 minutes, re-torqued the cylinder head bolts (which will be done again after a long drive, when the engine had been at a higher operating temperature), adjusted the carb, and it now appears to be running well.
New non-resitor type spark plugs were installed, NGK B5ES (6410). Incidentally, I'd initially ordered Bosch W8CC plugs from Rovers North, but what arrived were WR8CC+ resistor plugs. A query to RN resulted in them saying that these resistor plugs had superceded the non-resistor, but the website does say W8CC (at time of writing), so if you're looking for non-resistor plugs from RN, call first to see what you'll get.
Just waiting for the hood/bonnet to go back on, and the Land Rover is ready for some more driving.
This is just a simple pictorial history of my restoration of an original Canadian-import 1960 Land Rover Series 2 88" (or SWB - Short Wheel Base), LHD (Left Hand Drive) which I purchased in August, 2010. Later posts include photos of some of the things I've done with the vehicle since its restoration was essentially completed, although repairs and other maintenance are obviously an ongoing process.
