CORE PLUGS Range Rover V8

[sb-1]

Probably a silly question but,

My Range Rover has weeping CORE PLUGS,can you just bung some Bars Leaks into the Rad to stop it,or are they likely to blowout at any time?

Its a 1990 car and done 112000 Miles.

Cheers

Depends why they are leaking.

if they are corroding, then its a no win situation. They will get worse.

If for some reason they are solid, but leaking around the edges a bit, then perhaps something like Bars leak might cure it for a while.
It wont last forever though.

i wouldnt use bars leaks personally. it probably wont do what you want to, if it does, it wont last and as soon as you put it in you can start to have probs with it blocking what its not supposed to.
im not saying its instant death for an engine, but i know no one who has used it with any degree of success.
why not just change the plugs? theyre about a quid each arent they?

If you can gain access to them, replace them; as Paolow says the cost is trivial.

If you fit new core plugs, try using a smear of 'Wellseal' on them as you fit them (available from specialist engine component suppliers like QED or Burton, if you have difficulty finding it at your local motor factors).

If access is difficult, a 'bodge' solution I've used sucessfully on corroded core plugs is simply to degrease them then fill with chemical metal from the outside. Obviously makes them difficult to remove in the event of an engine rebuild (can be done - just a bit trickier), and means that they may not pop out if the coolant freezes, but then you always use plenty of antifreeze/corrosion inhibitor in your alloy engine, don't you?

Wire brush on a flexi drive and body filler. Used this on an XJ6 and was still sound when sold 4 years later.
