Hello...Newbie here...basic elementary question....replacing spark plugs that have been in the engine 16 years, with 85 k miles.... My question is....Is there a high probability of stripping the cyl head threads in spark plug removal after this amount of time & mileage??? I have no knowledge that the plugs in the engine have been neverseized..... Responses greatly appreciated......Thanks....

 

Nope. There is only one way to find out.

 

Well.....Looks like by the lack of responses, I don't see an overwhelming issue of threads being stripped out of the head....Not really a driveway job for January in NY, in the event of an issue....will take the dive in April......
