So I'm changing the plugs on my 01 Disco, and notice one of them is in
crooked. When I take it off, it's super tight. Seems the dealer cross
threaded the plug and now it wont go in all the way or straight.
Unfortunatley, I moved away from the dealer who did it and I can't remember
when it was in for anything that they would need to take the plugs out.
Possibly the service before 60k? Is this an easy fix? She runs fine, but I
know it can't be healthy. I appreciate any ideas. Also, what is the groups
take on BOSCH +4 spark plugs in a rover?

Thanks!!

Jamie,

if you're anywhere near chatham, i've got the helicoil kit, you're more than
welcome to make use of it.

I had the same problem, but it was a recovery service (not mentioning which
one but they cant sing) chap that did it.

Before you go the helicoil route I would try putting a thread chaser/ tap
down it , I used to have a sykes pickavant one but some scrote nicked it. A
really usefull bit of kit and it has got me out of the pooh a few times,
remember to spin engine over a few times after without s/plug in to fire out
any swarf.

On the occasion I had to helicoil in situ I brought the piston to just
before tdc and pumped grease down the plug hole to fill the combustion
chamber. Then I tapped and inserted the helicoil. Turning the engine
over slowly expels the plug of grease, followed by a brisk spinning
with the starter to eject the rest.

BTW I would leave well enough alone until the plug really needs
changing unless you feel it could work loose.

I have a kit you may borrow if near NW Surrey.

You might be able to use an old spark plug to re tap the thread if you
can't lay your hand on a tap and die set, On an old spark plug you
simply hacksaw a slot through the thread from the base (or electrode) to
make a groove almost the length of the plug thread, then insert the plug
back into the head and tighten it in and out a few times, it should cut
a clean thread by following the old existing thread but only if it is
not too badly damaged.

it is, of course, critical that it goes in straight... which might be a
problem.

I'm not too proud to say I did this myself UNDOING the plugs on my first
Rangie V8... Unless you have thin walled spark plug sockets then it's just
the way these things can go... It was a steep learning curve but never made
the same mistake twice.

The problem with the wider sockets is they brush up against the
block/manifolds (I forget) forcing the plug in to a rather nasty angle as it
come out and buggering up the thread in the process.

I know I'm not the only one to fall foul of this peril in this group.
