BEEDZ Posted September 12, 2020 Share Posted September 12, 2020 (edited) Is the core plug next to the starter motor 27mm? 2.0s Cih As mine’s leaking and no one seems to stock them locally anymore Tia Edited September 12, 2020 by BEEDZ More info Quote Link to comment Share on other sites More sharing options...
Jessopia74 Posted September 12, 2020 Share Posted September 12, 2020 How about a full set? Of one has gone, chances are other are close to need replacement anyway. £12 delivered is reasonable https://www.ebay.ie/itm/Bedford-CF-Vauxhall-Carlton-Cavalier-Opel-Manta-2-0-8v-OHC-CIH-Core-plug-set-/263893157822 Quote Link to comment Share on other sites More sharing options...

cam.in.head Posted September 13, 2020 Share Posted September 13, 2020 Yes sounds like it just leaking.shouldnt rust away that quickly. You Probably won't be able to get it out and reuse it so a new one is needed. A good clean of the hole and a splash of red hermetite is all that's needed. It should be a nice tight tap in fit. 1 1 Quote Link to comment Share on other sites More sharing options...
®evo03 Posted September 13, 2020 Share Posted September 13, 2020 Is there anything else that can be used besides red herm! Quote Link to comment Share on other sites More sharing options...
GTEPETE Posted September 14, 2020 Share Posted September 14, 2020 Practical Classics team use silicone when replacing core plugs.... and large socket to drive them in... 1 Quote Link to comment Share on other sites More sharing options...
®evo03 Posted September 14, 2020 Share Posted September 14, 2020 Silicone, as in cheap, nasty, bathroom sealant, i was thinking more of a heat resistant, water resistant resin or something, so it doesnt leak. Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted September 14, 2020 Share Posted September 14, 2020 it shouldnt leak even if you use nothing ,ive always used red herm and never had issues. you can also use blue herm or the liquid sealer as used on later oil pump covers that dont have a gasket. personally wouldnt use silicone but then never tried as never needed to ! 1 Quote Link to comment Share on other sites More sharing options...

You need automotive silicone.....comes in smaller toothpaste type tubes... eg https://coreplugs.co.uk/hylosil-instant-gasket-40ml-hig40# 1 Quote Link to comment Share on other sites More sharing options...

Absolutely, Red herm or equiv semi setting is best stuff for doing core plugs 1 Quote Link to comment Share on other sites More sharing options...
