My plugs are gapped at .045

[traildog]

Seems wrong to me and I've been scanning the forum and finding all kinds of answers.....Autolite 103's what should the gap be?

as big as possible until you start blowing them out because of boost.

stock is .060", but i always ran .045" because i was lazy and i was running smaller pulleys (3.2).

however, since you're turbo .045" seems right...unless you're running a lot of boost, then .040" or .035" seem more appropriate. it's all trial and error.

As i get all of them pulled, I'm finding them from .050 to .039. I have one plug to go. Scottydogs told me to remove the dog bone bolts to pull the engine forward so I can get to the last one. I want to do a compression test while I have them out. Can I do it without disconnecting anything else?

leave all the plugs out, then screw the tester in each plug hole, crank the engine over. it wont start because its got no plugs installed. and will spin faster with no plugs as well.

I can't get the last plug out.....

 

[traildog]

the disconnected o2 sensor is in the way and I can't get it out either.....

 

[Scottydoggs]

what one? and why? i can get my gorilla hands back there with the engine rocked forward. and you should have a plog back there, not much to be in your way.

You can do it...
And after you do gap them plugs at 0.035

if your plug socket has a bolt head on the top of it, try sliding the socket on, then use a wrench to break it free. or a swivel may help.

dam local parts store only has 606 plugs. Wrong ones, right?

 

[jrb1027]

ya just go to another store and get 103s. 606 plugs are 3 heat ranges to hot

 

[traildog]

did ya ever have a tool in the box you didn't think you were ever gonna use? Dam weedeater spark plug wrench came in REAL handy tonight...I got it out!

 

[Scottydoggs]

yup, sometimes the odd tool gets it done.

 

[traildog]

Back with the plugs...checking compression now

I was gonna ask you for that again! I lost my copy. Thanks.

not to bad, at least they are all close. you dump some oil in each cylinder do it again, its should up the compression a bunch. theres a dry and wet testing.
