Overtightened spark plugs?

Hi guys recently changed out the spark plugs and with the feeling To crush the spark plug washer I had to go 1/2 to 3/4 of the turn after bottom out contact which I believe is over the 15 foot pounds toyota recommends will this have made my spark plugs too tight you think? Also used anti seeze on E3 plugs , if good or bad not sure


thanks for the feedback

 

I dont know why you would purposely knowingly over tighten spark plugs but since you only over did it a little I wouldnt worry about it. Theres nothing wrong with using anti seize if you want, but you dont have to if you dont want to, personally I dont bother with it on my own vehicles or any I do tune ups on at work.

 

Your motor will probably blow up within 1k miles. id pull the plugs and re-tighen.

 

but seriously.....don't sweat it. grab a beer and don't be so stressed.

 

Google -> NGK do not use anti-seize on spark plugs

Be it NGK or Denso - matters not - both have same type of metal finish

 

E3s are a gimmick. Use the OEM Denso or NGK. And use a torque wrench. Never take a chance with spark plugs. Others have said Denso and NGK specify no antiseize, which is true, but I still use a very small dab at the beginning of the threads only.

 

Use a torque wrench next time if you don't have the "feel" on how to install plugs. Especially if your gonna stress about it after. I put anti-sieze on all of my spark plugs, regardless of what the mfg says. I pulled the original plugs out of a friends Kia with 230k on them. NGK, and those suckers were TIGHT, like I thought I was gonna break a couple. A little anti sieze will ensure that if I ever do the job again, they come out easier.

Regarding brand, just read the manual. It has the recommended plug and gap written in it. Dunno why people get confused about this.

 

I guess you’ll find out in 30k if it mattered or not

 

I have the 4 cyl. Ordered OEM plugs from Rockauto delivered for $24.I used torque wrench .. No anti seize

 

Living anyplace where corrosion is common place ECK, or any type of anti seize, even a small amount would be exceptionally wise.

 

a little dab will do ya.......

sparingly.........
