Re: Valve Guides or something more?
you have diagnosed correctly. However, the valve guides are cast intragal in the heads. If you don't want to remove the heads and have the guides knurled, you can purchase the "umbrella" type valve stem seals, and install them w/o removing the cylinder heads. You will need an air hold fitting, a valve spring compressor, and a lot of patience. If it isn't using a lot of oil, you might want to postpone this job and drive the truck for a while, it won't hurt the engine to have a little oil on top of the cylinders at start-up. I hope I have been helpful in this matter. As a side note, check the drainage on the cylinder heads to see if the heads are draining good. If oil is remaining puddled up on the cylinder heads, oil will leak down the guides. If this is the case, simply clean the drains on each head and you will have eliminated the greatest cause of the problem.
