Re: Cheap plugs?

Question

: Has anyone had a mechanic tell them that Bosch Platinum plugs are "thecheap: ones"?  I've got a problem with 2 of my cylinders not firing and the plugs: are fried with white powdery residue on them.  They're changing the plugs: again (I just put the Bosch on last month) and checking the intake andhead: gaskets for leaks.  I ask because the warranty covers the gaskets, but not: the plugs.  And he tells me the warrany WON'T cover the gaskets unless he: changes the plugs.  Sound fishy or is this pretty much in order?: thxTell him that you want to see the plugs.  Sounds fishy to me.  Bosch are notcheap and they are typically pretty good.  I'd want to see the plugs.  Checkthe post for wear or damage.  Check for oily or greasy residue.  Check the"L" (spark receiver) for damage and make sure a piston isn't smacking it.If the mech. says they are fried, I wanna' see 'em being pulled in thatcondition.  Just me.I'm impressed with rapid fires and ACDelco parts in general.  (Do notpurchase split fires.  You only need one good spark, not two+ weak ones.)For the cost of plugs, I'd purchase them just to preserve the warranty.Stripping down to the head is a P.I.T.A.!

Don't know, but the white powdery stuff says "lean condition" to me. Or could be heat range of the plugs are too hot.

Update:El Lobo, you win the chocolate chip cookie.  Two cylinders were running VERYlean as the fuel injectors on these 2 cyl were not firing at all.  Two fuelinjectors which, by the way, are NOT covered by the warranty.  Tell meagain, why did I pay $1300 for that warranty?Thx, all.

el lobo · Answer

That sux them not being covered by warranty. I thought they covered stuff that are not consumable. You would think injectors would be covered. Does your policy specifically state the injectors are not covered?? I kinda figured no gas to the cylinders, but ya never about these cars today..... Now where is that glass of milk for them cookies ;)

I had the same on my 96 Z28. The injector was gone and not covered by theGMPP warranty. If you have that type of warranty it has to be specificlymentioned or its excluded. I paid $CAN 1800 for mine and as far as I amconcerned it's not worth the paper it is written on (or in this case theplastic card). By the way what year is you car. Thanks.
