Thanks for the suggestion, I just didn't know if there was something special about them. Yeah, my dealership wants $150.00 for them and he would have to order them in. My truck is a 2001, but it only has 50K miles on it. I bought it in 2009, and have only put a few thousand miles on it myself. But the plug wires are still 13 years old, and one was rubbing on the exhaust manifold and would intermittently short out. So I decided it was time to replace them. Spark plugs only have 50K on them so they may still be good, I'll have to pull one and take a look. I bought a travel trailer last November, so the wife and I are starting to put some miles on the truck now. I replaced the battery this last trip too.
I saw those at Summit Racing, and I measured my stock ones, they're 7.5mm. So do I understand correctly that you're saying that 8.2mm won't fit in the plastic loom cover? Dang, a whole mm is less than .040"!!! Must be a tight fit. I'm not sure how attached I am to that loom cover...
I think those are standard plugs in there.... (not entirely sure on that....) I would definitely pull a couple, and have a look.
I have read a few threads that were horror stories about removing spark plugs from this engine. Sounds like they rust in place, the one I looked at tonight had rust on it. I was trying to see the brand and model of plug, guess I'll have to pull it to see what I'm up against. Are there good suggestions about pulling these plugs? Should I like spray WD-40 on them the night before, or what?
I pulled one of the plugs just to see if I was going to be in for a battle, and it came out easily. I'm thinking not even 20 foot pounds of torque. I remember now that I had the guy I bought it from have a compression test done on all cylinders. So the plugs have been out before. They are the factory recommended Champion QC9MC4. It looked like it was burning nicely, just a tan color. The gap was huge though, looked like .055" or .060", and I think it's supposed to be .045". There also seems to be some question about how much torque to apply to the plugs. I don't usually torque plugs, but they warn you not to over tighten them. Some sources say 17 foot pounds, and others say 26 to 30. That's a lot of difference. Is there a consensus of opinion about what torque to use on the plugs in a V10?
When I install plugs, I take a look at the sealing surface that goes against the head. If there is a 'gasket' there, I turn them in till they seat, then give another quarter turn. If it is just a tapered seat, screw them in by hand till they seat, and then turn them another 5 minutes. (look at a clock, it ain't real far.) Never had a problem with them stripping threads, or blowing out.
Same here. I do spread a bit of anti-seize on each plug's threads, then install the plug by hand to ensure it is not cross-threaded and tighten until good and snug - never had an issue with spark plug installation or having a plug backout. No torque wrench used for spark plug installations here..
