Sparkplug woes...



When I pulled this spark plug it was intact, and had a TON of loose deposits around the threads.

The deposits are light brown and almost the consistency of powder/flour.



I tried to get a photo of it..

I replaced the spark plug, with a random old one, that looked in fine condition. I cleaned it up and placed it in and the truck is running at about 90%.

Still doesn't have the 'umph' it use to have. The torque seems to be pretty low.

Photos were taken on my phone, and NO I did not spray the spark plug area with anything prior to the photo.

Valve Gasket replacement time?

Could I do that with simple tools and equipment at home?

Say...is that spark plug ceramic broken of in the first pic?? Those would cause hesitation and missing. My new 1,000 mile motor had a cracked plug ceramic and it ran like dog shiz under load...

The "flour" powdery stuff....you sure it's just not dirt dust? Little tipsky.....pull the boot off the plug and before removing the plug, get a can of compressed air or take a compressor air nozzel and blow out the area the plug sits in. This'll get rid of any of the dust/dirt/junk that accumulates in the plug area so it don't fall in the cylinder.



Do you have a full set of NEW plugs in the truck???



Yes it does appear to be a valve cover gasket up top and possibly a steering reservoir leak or another leak of some sort soaking the block. Unless it is the valve cover gasket seeping that low and covering the block.

I've yet to get a complete new set of plugs, I plan on doing it 'today'.

The ceramic wasn't cracked, first thing I looked for. But the insulation, fell out after a few light raps to get the dust off, onto the bag.

I've got ZERO cash.

And I'm trying to sell some extra gear/junk to make a few repairs.

These sparkplugs are only 2k miles old.. :(
