Hello guys, well today my truck started stumbling real bad on idle.. I took a look at the spark plugs, which I replace maybe about 7 months ago, they are NASTY! look at the pics! Oh yea and its consuming 1qt of oil in less than 500 miles!! Valve Stem Guides is the first thing that came to mind...what do yall think?, I just want to be sure of what the problem is.. 4 of them looked like these, the other 2 looked perfect. Sorry bout the pic quality, there from phone cam.

valve stems could be the problem, but they leak oil when its not running or when you shift. It could be worn rings, or both if your unlucky. How many miles you got on it?

I would lean more towards piston rings

Need to pull the head off and look at the cylinder's that those plugs were on

Looks like it burning coolant.

It has aprox 90k on it.. I replaced head gaskets not too long ago, I dont have coolant loss or overheating problems at all.. It consumes oil like crazy! And saw a little cloud of smoke on start up and when reving the engine.. Im thinking of running it till it cant no more and just replace engine. Damit...

With no over heating or coolant loss your rings are going or gone

If 3 plugs are like that shouldn't be to long before it goes. Especially if you ride it hard

damn... I guess start saving for replacement engine! This sux

definitely oil, most likely past the piston rings. Its obvious by the oil and calcium deposits on the spark plugs.

Does anybody know how much will piston rings and valve stems will cost?? Not including labor. I will ask mechanic for labor price.

Also what parts do I need to get it fixed?.. thnx

Piston rings will set ya back $100.00 - $125.00. You could do this your self

Valve Stem Seal is roughly $25.00 for a set

New valves will probably be about $10.00 a piece

This is all depending on if your cylinder walls are not scored also. If the cylinder walls are scored and depending on how bad. Your looking at getting the block machined or if they cant replace the whole block.

you could do all the work if you had an engine stand and some tools. You could really save money that way.

Well I know the basics, i mean the deepest ive gone in an engine is to replace injector seals, beyond there ive never removed or seen anything.

There are vids on youtube and instructions on the internet, it doesnt have to be the same motor, you just need to know the basics becuase motors are all somewhat similar on the inside. The videos from BoxWrench are pretty good.
