A very happy New year to everyone.
Firstly, my apologies for some many questions. I still have much to learn about the Land Rover world.

Todays questions related to the terminating plugs that screw into the block to seal the Oil Gallery and the Bottom Rocker Tube on a Spread-bore 2 litre engine (1954-58).


The upper tube is referred to as the Oil Gallery Pipe (#09034) which is closed off at the front of the engine by Part# 03129 and at the rear by # 216933.

The bottom tube is the Bottom Rocker tube, (#239089) which is closed off at the front by #12455 and at the rear by #3088 (now believed to have been superseded by new part Number 536577)

It is the rear Bottom Rocker's rear plug bolt that O need to find, as mine appear to haver been misplaced during the strip down.
It would appear reasonable to assume that as these 4 bolts all screw into the block, for the same function, that their threads and diameters would logically be the same.

I would to locate both these plugs, but cannot get reliable results from those Part numbers.
Can anyone tell me with the thread on the 4 plugs are the same? Are they interchangeable? Where can I buy them?

Many thanks
Jeff
