help! Corroded valve caps on real car

[Timee80]

ive got 2 corroded valve caps on my real car. 2 have come off no problem but the other 2 are really stuck. I used some grease when they were put on but they are going nowhere now. Ive tried using 2 pair of pliers but still not shifting. What do i do?

WD40 soak and gently apply a little heat

[bodgit]

If the wd40 does not work soak some cotton wool or some tissue paper in vinagar and put it round the cap with a plastic bag and tape it tight. Leave for an hour and see if the vinigar loosens it.

Mole grips, or a small set of Stilsons.

cheers folks, ill give the ideas a try

Grab a can of shock n unlock from Halfords... works a treat for releasing stuck things.

Are they metal or plastic, a set of grips should get it off no probs.

If its plastic and there still not budging, boiling water to warm the valve cap up, then try the grips.

Do you think someone may have glued the caps on, little "shine a lights" have been known to do similar ... Might have to get a stanley on the scene. Just watch your pinkies and the wheel and tyre psssstttt noises are not good.

if theyre metal Plus-gas from any good car bar will move them.

failing that, dremel and cutting disc.
