Installing Spark Plugs....

[Powerzen2002]

Ok.  I just installed my NGK V-power spark plugs.

I know this is really not a great idea, but I used a deep ratchet to put them in since hand screwing would take years!

I just was wondering, how would I know if I have over torqued or under torqued the plugs.  I dont wanna have tightened them to much that next time I gotta pop the valve cover becasue the plug broke off or what-not.

Thanks.

next time look for the torque specs and use a torque wrench

don't quote me on this, but I believe you're supposed to torque them down to 14-22 lb.ft. ... or whatever it's measured in here in the states. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sigh.gif" border="0" valign="absmiddle" alt=':rolleyes:'>

YOU HAVE A TURBO <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'> IF NOT WHY ARE YOU USING A COLDER PLUG?<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>

I actually called up NISSAN, they recommended NGK plugs.

That is why I put them in.

Ok. &nbsp;Im not a pro on the spark plugs, so heres &nbsp;question.
Running a colder plug on a non-turbo, what would be the side effects? &nbsp;Jumpy engine? &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt=':('>

There's nothing wrong with using a hand ratchet to install sparkplugs, that's the way it's normally done. Screw them in until you meet some significant resistance. Then, if the plug has a washer (which ours do), tighten it an additional 1/4 turn (90 degrees).

No, a plug that's too cold for the application will just have a tendency to develop carbon deposits over time, which might cause misfiring ("jumpy engine") when they get real bad. New plugs that are too cold won't make a difference.

Anyway, you're probably not using cold plugs. NGK plugs have two numbers in their model # thingie: the -xx at the end is the gap they were designed for (-11 means 1.1mm, or .044 inch) and the other number is the heat range (5 is stock, a higher number is colder).

Can you PLEASE NOT USE CAPS IN ALL YOUR POSTS.. IT"S BECOMING ANNOYING

thnx <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/cool.gif" border="0" valign="absmiddle" alt=':cool:'>

also.. &nbsp;Torque for the plugs is 12-14 I believe.

Becareful not to cross threads when you are screwing in your spark plugs. And make sure all the plugs are gapped the same distance. .044 (someone stated this earlier)

Just makesure not to use too much force.

RIF- Reading Is Fundamental

All your questions are specifically answered in the convieniently placed manual in front of the seat next to you (read: the gove compartment).

In there you will find the torque specs, procedure and even the proper plugs by model number including heat range and gap that are appropiate to your car.

Never specified what engine you were running but on my 93 KA, a gap of 1-1.1 mm is spec. &nbsp;Found out the plugs I just replaced were two heat ranges colder than stock, and so far I have not nocticed a difference running the normal range plug I installed.

Here's a very good webpage on
heat ranges (http://www.ngksparkplugs.com/techinfo/spark_plugs/overview.asp)
