P'raps he thinks its coming from there,but its really coming from a dodgy core plug?

[skates]

ok now im worried. wots a core plug?

[zakboy]

if you look at terrys picture the round thing slightly below the hole i think is a core plug they tap in to the holes they occupy

[dobber]

core plugs a steel friction fit plate which fills a hole left from the casting process [i think]  used to pop out when the engine froze or start leaking when they rusted through from the inside out. easy to replace though. hardest part used to be access when engine was in car or it was one between engine and gearbox.  can anyone confirm?

[zakboy]

yes Dobber there purely to protect the block from cracking in freezing conditions when antifreeze is not present in the coolant

ok now im worried. wots a core plug?

this is a photo of a reliant cylinder head. as you can see i wrote on there to show you whats what
the small one is oil
the large one is water



now you post a photo showing us where the problem is and you might get the correct info to sort it out

[zakboy]

there is a small hole at the back of the engine on the block. i think its where the thermostat is

The thermostat as stated is at the front of the engine .
The core plug is round but is not flat to start with .
It is dished outwards { bulges outwards } and is a neat fit into the recess in the head .
The hole needs to be thoroughly cleaned out before attempting to insert the core plug .
When it is inserted into the hole in the head and hammered in the centre of the dished out part it spreads to touch the side and forces against it to seal .
The maximum sealing point would be when it was flat
Lots of folk go too far and hammer it too much thinking that the more they hammer it the tighter it will get . Unfortunately it has the reverse effect because the core plug becomes dished inwards with the result it pulls it away from the side .

Question for Fifer.....Is it still possible to use the sliding type points ,even though I have cut the post off to fit the module?

The early Red points unfortunately do not fit the Blue point baseplate .
I will upload piccies of baseplates for both types and point out why one does not fit the other

The Blue points have a locating peg on the back of the points which sits in a hole in the base plate and the adjusting peg is down at the bottom of the points .
The Red points have a locating peg on base plate and the points pivot is hollow and fits over that peg
The adjusting peg is down at the top of the points .
