Blue Smoke After Ten Minutes Of Idleing

[Mr Camouflage]

Generally bad rings will smoke on acceleration or constantly, and bad valve seals will smoke after idling for a while, or on deceleration, but not all the time. Or so I'm lead to believe.

nah bro its blue it could only be one of two rings or valve seals given the situation i have more than likely its valve seals i hope than rings....

You still should take care of both while you're in there as mentioned above. If you just do valve seals, you'll be back in there doing rings sooner than you think. Check the compression. That will give you a better idea of the state of things.

Head gasket failure could cause oil to leak through into the cylinders not just water.

If your so sure it's rings and seals, why ask? Just replace both. The extra cost while your in there will be minimal. Replace the head gasket too while your in there just in case bro

Ya think??!

Haha ^. I had to throw it out there (just in case)

you guys got jokes of course i would replace the head gasket after taking the head of thats like trying to reuse used toilet paper it just wont work eeeeeew but yeah i talked to the guy i bought it from and he said that the head gasket was just replaced not to long ago so i guess im going to just get the head redone for the valve seals and go ahead and put new rings in aswell.

putting in new valve seals ain't rocket science unless you just like giving your money to the local mechanic shop. Read some of the posts on how it is done. 130 K on that engine isn't a lot of miles. Mine has 225k and doesnt' burn that much oil.

Valve seals are easy, guides are a little more work, and rings/bearings are even more work but I do all of the dissasembly and assembly myself. The only things I pay for are the parts and the machine work. From the time this discussion began to now, 6 days, I would have already run the tests to determine what's needed, tore it down, purchased the needed parts, sent the stuff to the machine shop that needed to go there, and either be finished or in the final assembly stages depending on how quickly I wanted it done. But that's just me, I've been doing it over 40 years.

And you may have slightly more free time on your hands than some of us...
