Alex, that might not be a good idea.:thx i used 14 the amount that made them open but i will re fasten them @ 13 lb ft thanks for the big help
Dear sir i bought AC DELCO plugs and they dont have washers i am confused of fastning i know vortic is alomnium and i afraid of making a bad move and destroy the machine plz help me professional ingine guys any body help thanks.Alex, that might not be a good idea.
The "crush" washer (on the plug) might leak if you reset to 13. The washer was "crushed" to 14 and might be loose at 13.
That's just my opinion, I could be wrong.
No i did not use any thing on the plugs just checking gap @0.040 inches and they were set to the same but what to say the plug is made in japan! Do you belive that and its AC DELCO.Alex, sorry, I may be confusing you. This "crush" washer is a gasket for the plug. It is a loose washer on some plugs and part of the plug body on others. You are correct, the 4.2 plugs have it as part of the plug.
However, my observation still applies. At 14 lbs, the gasket may be compressed too much to properly seal at only 13 lbs.
If it was me, I'd leave them alone.
But, someone with more plug knowledge may read this and help us out.
By the way, did you use any anti-seize paste on the plugs?
OK, good.No i did not use any thing on the plugs just checking gap @0.040 inches and they were set to the same but what to say the plug is made in japan! Do you belive that and its AC DELCO.
