Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

How often do you change your plugs? How about the ignition coils?

POST 2Original post

Quotes source post: 640812

Your going to get a ton of different opinions on both those Items. I don't change coils unless there is an issue with them. Such as misfires or cracks in the housing or other defects. Something that affects their ability to work as they should. Plugs more or less the same: Modern day plugs last many miles. You can pull them and check them on what ever schedule you think is effective. But something to keep in mind: If you pull your plugs and replace them you want to replace the "crush washer" on them. That washer is designed to seal the plug to the head. They are a "one time use" washer. If you reuse them over several plug changes you risk minor compression leaks that in most cases you cannot detect. I don't know about other people but I have a very hard time finding those crush washers. So if my engine is running right I leave things like plugs and coils alone. I hook up my vacuum gauge, and scanner once or twice a year. I also watch things like fuel mileage and just the way the car performs and feels. By doing those things I know if I need to look at my plugs and or coils.

POST 3Original post

….the owner’s manual. Written by the folks who built your car.

POST 4Original post

Ignition coils either work or don’t, so I won’t replace them unless they fail, throw codes, etc. I do check plugs and replace them just about every 10K miles. When you take time to remove them, why not put new ones in, they are cheap enough.

POST 5 / ORIGINAL POSTEROriginal post

Quotes source post: 640818

That's a very good point. However, aren't most of us follow more frequent maintenance schedule? Like oil change?

POST 6Original post

Never replace mine....usually dont have them long enough to put 10k miles on them. Only do about 5k miles per year anyway

POST 7 / ORIGINAL POSTEROriginal post

Hi blue62, Don't you get one crush washer with a new plug?

POST 9Original post

My 98' (5 speed w/91,000 miles) runs very well. I drive about 4,000 to 5,000 SUMMER miles a year and typically get about 27-28 mpg in mostly city and some expressway driving. In the 16 years I've owned the car I've never had a "tune-up" done. Even though the car appears to run great, my "indi" recommends that i should have a tune up done....he suggests ALL plugs, ALL coils, replace Serpentine belt, Fuel filter and Air filter (I did change the air filter 2 years (8.000 miles ago).....$1,300. Since the car is running "great" (in my opinion) and there are no thrown codes should I go ahead and get a tune-up or just continue to have fun and drive it and monitor it?

POST 11Original post

or drive down to St. Louis and I'll do it for half that savings and be done in a couple of hours.

Stl-986, Is that offer valid for NJ residences too?

POST 14Original post

Quotes source post: 640835

Yes that is correct. It is on the plug. What I was referring to is: If you pull the plugs to check them as part of your maintenance schedule. Then replace them (because they look fine). You need a new crush washer. In days gone-by: You pulled your plugs, cleaned and gaped them every time you dressed and gaped your points and set your dwell. (about every 30000-35000 miles) So you replaced the crush washers every time you cleaned gaped and reused your plugs. Back then the washers were very easy to come by. I would have 20-30 in the tool box. Not easy to find them now days. I have a schedule for all maintenance items on my cars. But I also let the car tell me what it needs. Example: I have oil changes on a 5000 mile schedule. But if the oil is discolored or dirty when I check it with only 2000 miles on it I change it.

POST 16 / ORIGINAL POSTEROriginal post

Quotes source post: 640843

Perhaps there is a business opportunity there - sell crush washers on Amazon. How are you checking the oil discoloration? There is not much oil on the dip stick. From the filter housing maybe?

Yup so is 6 Flags and the Zoo (largest free zoo and one of the best in the country)

POST 19Original post

Quotes source post: 640849

From the dipstick. The Porsche is a little difficult to see on the dipstick. So just look at it or wipe it on a whiter paper towel. Several dips and wipes if I need to. My Honda CRV and Ford truck. No problem to see the oil on the dipstick.
