Hi all, my landy has been running so good after fitting new turbo and de egr valve mod and then ast week i noticed ive been using or loosing water/antifreeze. Been topping up all week on short journeys to work, but today had a good look over only to find a weep from a core plug on the block. Well there seems to be three of these plugs on the drivers side and the two that you can see easily look fine, but the one behind the engine mount fitting is bleeding bad!! ,especially when engine is running. Typical . So this weekend is set aside to do plug. i have ordered from dealer and got an extra one just in case. A stagerring £10 for two. Any tips, or has anyone done one of these or heard of them going. The landy is a 1999 t5 discovery. Seems to be mixed veiws weather to put back with sealant. Anyway look forward for your thought Regards all , Mark
I had the same one go on me a few weeks ago. I replaced them all on that side whilst I was at it, paid 69 pence each from a local factors!
The worst part of the job is removing the inlet manifold as you lose some skin on your hands doing it! The other pain in the ass is removing the engine mount as one of the bolts is fairly hard to get at and you run the risk of rounding the bolt head. The alternator is also in the way and will need to be removed.
I found the best way of removing the core plugs was to centre punch the middle of the core plug (which deforms the plug) and hammered one side repeatedly with a small cold chisel or old screwdriver (using a hammer), until the core plug twisted in its hole, after which I pulled it out with a small pair of mole grips.
To replace them, make sure the hole is clean and then smear a bit of sealant around the new core plug, and hammer in using a socket to ensure that it goes in even. Be careful not to hammer it in too far.
Whilst you have that side of the engine exposed, you may as well replace all of them just in case another is ready to go!
Good luck - hope it goes well
