Has anyone stripped or cross threaded a spark plug hole ? Can it be re- threaded without removing the head ? it can happen that you cross thread when re fitting a plug then when it's removed again the thread will no longer allow another spark plug to hold tight...

They can be re threaded without removing the head.
the spark plugs presented themselves easily as it's a vertical in line 4 ..Not so easy with a V4 or worse still flat 4. No mention of a vacuum cleaner to remove any metal particles

Yes and yes. Easy to cross thread. My garage did mine for me, thread cleaned and it was OK. He said he could replace the thread if necessary. In my case the cost was minimal.

Unplug the lead Unscrew the plug Screw the new ones in Torque up Plug the leads back on and drive off That's how it should go and often does Most of the problems are avoidable Don't change the plugs while it's raining Don't leave the plugs in past 100,000 miles Don't over torque Don't under...

you had yours re - threaded ? I've not changed one of my plugs for over three years as I'm sure it wont go back in.. I didn't see the guy hoover out the inside of the cylinder head
Don't overly worry about the metal swarf
Start the engine with the plug out, blows the majority out
The rest will either pass the exhaust valve or get burnt off
There not big enough or hard enough to cause any damage

Is yours actully damaged, or are you not confident they will come out okay

My guy said he used a mirror to view the thread and then set about clearing it and pulling the thread back before very carefully putting the plug back bit at a time. Mine was cross threaded by a previous owner and I replicated the mistake and by the sounds of it like you lacked the courage to really have a go. I have a back problem too which means that spending an hour bent over to do this was not a reality. He assured me it was not difficult to get the new plug back in correctly. Just very fiddly, but he is a very good mechanic and engineer so whats easy for himwould be more taxing for me. Its always best to start plugs by hand, especially when they go in at an angle and its difficult to judge it. With the Panda I feel its best to change one at a time so you can judge the correct angle of insertion by the second plug of each pair. My garage man said he could have managed to put a thread insert in the head if required without head removal but he was really glad he didnt need to. I feel that actually stripping the thread is unlikely and hope youwould be able to carefully get a plug to follow the correct thread. The problem then is to remember the weakness next time and be ultra careful. That is where I went wrong.
