Hi, my 351 4V Clevo manages to blow the No. 1 spark Plug about once every 2 x weeks. No other plugs are blowing, just the No. 1
Ive tried to clean the plug & put it back in, but the plug seems dead.
Any ideas why this plug continues to die.
Plugs are hot NGK,s

Thanks,
Brendan

Have you checked the plug lead? If it's no good, the plug won't fire properly.
Also check the compression of No.1 cyl & check for vacuum leaks at No.1 also.
Cheers, from Mal.
