Cheers Derek, Dad & I had about come to the decision today to replace all but the large one behind the flywheel that you mention.
Need to get some 'wellseal' now!!

If one has corroded the others probably aren't much better.
Take 'em all out and then clean the sludge out of the block, you'll probably find plenty of brown sludge around the bottom of the bores. Getting rid of that will help with cooling.
Leave the big one behind the clutch - it's the cover over the end of the camshaft - it can be left unless it is leaking oil.
In the factory workshop manual they seem to use "Wellseal" for most things - so this might be a good bet.

I think for peace of mind i would renew all of them as they corrode from the inside but i guess it depends on how tough they are to remove.At least those on the side of the block can be done with the engine in the car if youn don't do them now.
You're making some nice progress there Jason - looking forward to seeing her back on the road |

Thanks Steve, I think Dad found something similar, maybe even the same article.
It was the smaller of the 2 behind the clutch that had a hole in it, Dad took it out today but apparently it took quite a while as it was well stuck!
I'm undecided whether or not to change all of them whilst the block is out. It would be nice to know they are all new and by removing them allows the block to be well flushed. On the other hand if they are good then should I leave be? Decisions, decisions!!

Hi Jason,
from memory, and it'a along time ago, i didn't use any sealer when i replaced the core plugs on my old H120 - just drove them in.Didn't have any problems after replacing them.
Don't forget the one behind the bellhousing as it's inaccessable when the gearbox is mated up.
This one was leaking on my old car so whipped the engine out and replaced them all. |

Hi JPSH.
I renewed my core plugs and used a little jointing compound in the hole before fitting the plugs, the trick is to use a neat fitting socket to drive them in square. Not sure what compounds you guys use there, but it has to last a long time so use a good one.
Some say it is not nescessary to use any sealant or compound.
I am sure I don't have to say you must use quality anti freeze in the coolant system.I have seen many corroded heads , water pumps elbows and core plugs.
regards
Jan. |

Is it recommended to use some form of sealant/glue etc when fitting new core plugs?
