could,it be that the sealant is really insulatin the plug too much and causing it to produce less spark.
I wonder.
anyway i did speak to few mechanics and i dont trust em but they are telling me i may have damaged the cylinder and may have to have it machined.
i mean they wanna do a whole new valve job on my car.
what do u think.I mean my car had 200,000 plus miles but it ran darn good.

I was also wondering, do u think i n my car will ever run the same after this, and do u think i shud get a valve job anyway.

Thanks
help.
