stuck tyre valve cap

[dieselnutjob]

The 607 has tyre pressure sensors, and normally I keep plastic caps on them, but I lost one and had one of the original metal ones in the door pocket so put that on.

 

Now the bloody thing has seized on.

 

If I rock it gently with a pair of pliers I can see that the whole valve is rocking in the rim, so if I just crank on it the valve will spin inside the rim and bust off the plastic sensor inside which would be bad.

 

One option is to take it to a a tyre place, they can push the bead in on their machine to get to the inside and I suppose undo the mounting nut so that it can be held properly or something.

 

Another option is to just cut the cap off.  I guess if I grind the end off so that only the threaded barrel is left I can get oil into the threads from the other end, or even try and split the side of it off.

 

Anyone got a better idea?

Some alloy valve caps I had did this - two pairs of pliers sorted it  - one on the cap one on the valve stem to stop it twisting.

I was just going to suggest the same method, i stupidly put some alloy caps on the mrs car, that's how I removed them

Chap at work had this, went to check his tyre pressures one night and they were seized. I told him to take it to the local tyre place as if they fucked it up, they could fix it there and then, rather than me having a go and him having a flat tyre in the work car park.

 

10 mins later, all off, new plastic ones on with a smear of grease, and he had to force £20 into their hands for doing it, they didn't want paying (I think they used the 2 pliers method)

12 hours and no suggestion of hammering a smaller cap on, this place isn't etc.

That newfangled tosh isn't worth the electricity for the computer it's designed with by a SEM in Bangalore.

[dieselnutjob]

well it was the cap that came with the sensor, I didn't particularly want metal caps

I had exactly the same problem at the weekend with the low slung sporting coupe of minor irritation. Got some nice smart valve caps, black metal (alooooominum?), put them on at xmas and now can't get two of them off. Tried boiling water, a bit of wd40, plus gas, sexual swearing and mole grips on the valve + pliers on the cap and still won't budge, just splits the rubber cover on the valve stem. 

Wish I'd stuck with the usual shite plastic ones. That will teach me to not make the car look nice, don't know why I bother. Tyre place Saturday morning I think.

Having to drive to a tyre place to adjust the air pressure.

Now that's what I call progress.

Oh, and before everybody again slags me off as being backwards, my 1990 Corvette ZR-1 had Eagle Gatorbacks with pressure monitoring.

Back then, those things worked, because engineers still knew what material combination is.

[dieselnutjob]

There really isn't room for pliers to grip the stem

 

 

fortunately a couple of doses of WD40 have allowed me to twist it off with some molegrips

Metal valve caps are the work of Beelzebub himself.

[Timewaster]

A little bit of heat perhaps?

 

Don't "cherry" it!

 

Or can you get some plus gas spray up the base of the cap by splashing it back off the rim?

 

Anyone lend you a dremel?

 

Finally as a last resort hammer a smaller etc etc
