Stuck Sparkplugs #2 and 3

[Bo525i]

Can´t get sparkplugs #2 and 3 out..

Any good tricks available apart from WD40 etc. :)

Try when the motor is warm.

Be careful, if the plugs have rusted into the alloy, then they will gall and damage the threads.

Just crack them loose when warm, removing them even if not rusted WILL GALL the THREADS!!

If they are loosened and fighting try some PB Blaster in the plug holes.
Work them back and forth a little at a time, be patient.
I do not recommend attempting to remove plugs from a hot or warm aluminum head, usually a recipe for ruined treads.
Worst case ie rethreading the holes, not as scary as it sounds but stil a pain in the ass.

on the ford 4.6 and 5.4 and the bmw E39's with the 2.8 motor... The ford factory bulletins for the 5.4 which is famous for seizing plugs and destroying the threads in the head is to start with a head not cold and not hot, Room temperature or slightly above, in other words run if for a minute or less so the head is just warm to the touch,

Then you back the plug out 1/2 to 3/4 of a turn. Put 2 or 3 ounces of PB blaster down each plug hole up the level of the porcelain or so. I let the really seized ones on a ford sit all day and tried them the next morning , first i screwed them back in and then slowly started turning them out, if it got too hard i turned them back in a half or so and worked them out gradually. Previously i always did them dead cold and the results with this room temp was much better. I also tried BG penetrating oil and the PB blaster worked much better so it evidently does make a difference.

thats my recipe for getting out any stubborn threaded fixing

[Bo525i]

They´re deadstuck all the way down, no movement in either direction.. won´t budge at all.

Thanks guys, now I´ve got something to work with! :)

Gonna have to lean on 'em. Good luck

When mine got stuck, I went with the gently gently method... Otherwise known as a breaker bar. Haven't had any problem and I've took them out since. *Touches wood*

Don't think this is the recommended method though. :p

My sentiments exactly. Its just knowing how hard to lean
