 Posted: Mon Jul 08, 2019 12:30 pm Post subject: Are these plugs oily? And what about gapping? |
 |
|
My first voyage into servicing my own engine. My 85 vanagen. usually starts without any gas and bops around town so nice. But a few times it hasn't wanted to start then I put some gas and perhaps flood it (once it started easy 20 min later once I had to wait overnight) the over night time it backfired on start up. I pulled the plugs. Here is a picture of one they all look the same. I am not sure if this matches an oil laden plug or if its just black. Also the gapping was off between the 4 plugs one as tight at .25 one as wide as .37. Would this cause starting problems?
yes there is some dirt on the threads I will wipe it off.

Definitely will cause start problems - get some new plugs and replace, then practice cleaning and gapping on the old.

and should I expect new plugs to oil up fast? Im not sure if you ment these are oily
WELCOME TO THE VANAMADNESS!! |
happy to hear and good idea with the practice. What do you recommend for best plugs. I am not a perfectionist but am scared to death to drop another 1,500 on this van later.
And yes I have recently gone van mad. I just bought a 71 bayview to drive from CA to Cleveland next week so I can sell it. Never done anything like that before so yes I am Vanmad right now.

NGK Spark Plugs - BP6ET are what I used and are favored by many.
Here is one handy source:

Harbor freight makes a decent plug cleaner if you have compressed air available. |

That sounds a bit small - sure you're not thinking of the old trick of using a matchbook/match to set points? |

No I guess I made that up in my mind while I was typing . The rest of the world calls it a bay window.

plug gap is .026"+/-.002" 
NGKs, hands down.
BP6ET--which you wont need to gap--is my best choice.
BP6ES--which you also won't need to gap--if you like the older style.
il like the P ones with the Projected electrode
spark plugs and have the injectors cleaned/flow tested. change the injector seals while you're there and you've got a good starting point.
good luck with that epic bay window journey, OP

mils are sometimes thou's so i guess technically you could say 3 10 thousandths of an inch ,or you could say 3 milimeters, but three mil can also mean 3 thousandths. or 1/40 th of a millimeter.

Long used those, too, and just put a set of these in. All were above the recommended gap, one was sloppy enough I'd guess .036" or better.
Closing a gap is never as nice as opening one.
And Yes, your plug looks quite rich. Are they all like that?

yeah I did everything carefully and this morning it started up . Then I drove it 20 feet and stopped it cause I forgot something in the house. When I tried to start it a minute later It coughed instead of starting. 20 minutes later it started.
I will follow through with your next steps after my epic bay window journey . Is there a map of recommended dub mechanics for fools like me? I will drive from shop to shop till I get to Cleveland.

The thickness of your finger nail, is close, most think plugs come prepared gapped, yes they do, but NOT for a vanagon, they are pretty gapped for the car the manufacturers think will use the most, modern ignition systems are more powerful, and can jump a big spark across a bigger gap, with a less powerful ignition system jumping a bigger gap, will weaken the spark.
Use NGK BP6ET plugs
