When I first joined the forum Gippsland warned me of the delights of changing spark plugs on a lumped Jag (or any small block chev with headers I guess). I enjoyed this character building experience today.

Pictured below is a handy tool that made the work easier. There is just one plug that is a nightmare and one really awkward, the rest are routine. The pass through socket helps squeeze into tight areas and lets you get a open end or ring spanner on from the side. I ground down an old generic spanner to get clearance from exhaust pipes.

If you had better metal working facilities and skill than I have you could probably knock one up from a standard socket. Its a Snapon Tools item therefore expensive, but in this case worth it.

Much respect and thanks to the last person who did the plugs on this car. They were just snugged up nicely and not tightened by a mongolian arm wrestler.

The right tool makes all the difference. Changing plugs on an aircooled 911 is damn near impossible with out the factory toolkit.

 

They should never have named the type of washer used on spark plugs as a 'crush' washer - too many people take this literally.

Hi Steve and all,

Many years ago, my daughter had a Suzuki Across m/bike . . . 4 banger DOHC for a total of 250cc. Wicked; and she reveled in making it scream. Thankfully, gave bikes a miss before graduating to the Hyabusa.

You guessed it . . . getting to those plugs on the Across was really nasty . . . removing/replacing one of the four was downright impossible without the precise tool you have shown, and which we quickly purchased. A job to be avoided suddenly became doable with this pass-through socket.

I am changing the spark plugs on my 2005 Jaguar XJR. I have done all but the Driver side rear plug. There is insufficient clearance to get the coil pack out as far as I can make out.
There is padding on the body in the way but even if I remove that it still does not seem to give adequate clearance.
Anyone know how to get this particular coil pack out without breaking it?

 

Ok when I moved the padding I found the access panel. Problem solved. Next its the super charger belt and the utility belt while I am at it.
