I was going to try and change the spark plugs in my motor, I think they're due. I know my engine specifications but I don't know where online to find the proper gap for my engine. Does anyone happen to know a good resource where I can look something like that up?
Generally if you're buying spark plugs for modern cars you're getting a pre-gapped plug that doesn't need adjustment. Otherwise, you can use the factory shop manual to find the proper gap - and you can usually find a downloadable PDF of that manual on the internet pretty easily. They're nice in a pinch even if having a physical manual you can make notes in and stuff is better.
Is that by sparkplug? I think they need to be gapped at 0.032 at least that's what I saw for my motor for Champion spark plugs. I am assuming the number is determined by motor. That's part of my issue in finding the number, because I have a '74 Jeep CJ6 3.8 liter inline 6 and I am not finding data on it anywhere.
Do you already have the Champion plugs or will any plug fit the bill? This NGK listing (my personal go-to plug brand) shows 0.035", while this Denso listing shows .044" for their plugs..
If you've already got the Champions I'd give something in the range of 0.032"-0.044" a try. I'm guessing you're not trying to put big power down, so close enough will do.
hi, thanks!! really appreciate your help. I have Ford Motorcraft sparkplugs. I live in a place where mechanic work is so backwards, they use old washers and things to gap plugs. I literally had mashed up banana in my differential when I first bought my jeep, it was used on a coffee plantation.
Wow, that's some ingenuity for sure! My knowledge isn't expansive or anything but I'm happy to help a comrade out :stalin-approval:
Fucking love wrenching, but I mostly do diesels, sorry.
Actually, when I look at Champion's website, and do a part search for plugs for a random car they pop up the correct gap as "additional fit criteria"
