Spark plug boot problem.

[JetspeedCamry]

Can't get the spark plug boot to fit all the way in on my rear bank. I took it out to see if there was any oil leaks in there. It was all good, so i tried putting back in and it soooo tight. The metal makes contact with the tip of the plug because I started the car to see if it wasnt connect..and it runs fine. But it won't 'clip' in...what can I do? Grease?? Or maybe warm the motor up and then try. I was thinking i may have 'moulded' into shape because of heat.
Thanks.

Sounds like the clip in your plug boot that connects to the tip of your spark plug is messed up. Try using a different cap from one of the other cylinder to see if it fits. Either that or you are running wires not meant for your engine.

There definetly the right ones for the car, coz the fit ok when i got them. Just seems quite hard to get on now, as if the rubber is stopping it from clicking in. Could it be that they have moulded to a shape from heat? Should i try warming the motor and then doing it?

I do not think warming it up will help but if you do not have good contacts with the sparkplug, you will have missing during running, as it arcs in the cap.
Are they stock or??????

there is a grease for plug wires, called silicone grease, or silicone grease for spark plugs. That along with anti-seize are essential for installing spark plugs, you should be using them. You might be able to find both chemicals at an autostore in like a little tearable package for less than 2 dollars.

It's actually called "Dielectric Grease". It is available at most auto parts stores. Just put a dab on the metal inside component of the spark plug boot and try to put it on the plug. If the metal portion is deep down inside the rubber boot try a q-tip.

Warming up the car and trying to install that wire again first is a good thought; many times this works as the rubber becomes more flexible when it is warmer.

anti-seize is also good, especially if you often change plugs. It can also reduce the risk of the dreaded stripped spark plug hole...

Cool. Thankyou guys for your replies.
