    Anyone notice their spark plug tube seals leaking from the BOTTOM? My tube seal on cylinder #2 (middle cylinder) has a very slight oil seep.

    Does anyone know if our tube seals are threaded in, or pressed into the head??

    Sorry to thread jack.

    That is 100% correct and 100% wrong. Most spark plug brands do come pre gapped however they all have the same risk of rough handling during shipping. It's a long trip from Asia to the USA or wherever you happen to be.

    I just finished changing my plugs. I changed them once at 100k mikes and this change is at 200k miles. I check gap on all plugs before installing them. You would be surprised at the problems you find. Sometimes they are to close and sometimes to wide of a gap.

    Two of my new plugs were gapped perfect for my 200k mile change. One of them was 0.03. It costs no more than $2 for a cheap gapping tool and it takes about three seconds to check and correct each spark plug.

    If you are cautious enough to use grease on your plugs, but not cautious enough to check the plug gap, you might want to reconsider doing your own mechanic work.

    I'm a firm believer in NGK plugs. I run them in everything I own. I change them every 100k miles.

    On this change, the old plugs were. 050 across the board. I could have probably got another 100k miles out of them.
