2005 Valve Guide Seals

Has anyone heard of a problem with the valve guide seals on 2005 88" Twin Cams? I have almost 42,000 miles and lately the oil pressure won't come up right away and the oil light stays on till it does. If they take the top end off the bike will they automatically replace the rings, especially with that kind of mileage? It seems a no brainer to me but I'm not sure what to expect.:

Yes.

My buddy took the opportunity to go to a 95 kit because the valve stem seals were shot. Especially the back one and it was covered by his warranty. On his Ultra you can pop those plugs out and back in no time and he had to clean the back one every 100 miles or so. I'm not sure if it's a recall or not but it must be done. He only got 20,000 out of his. Good luck.

In 05 and early 06 HD used a thin valve seals. need to replace with thicker and better seals.

Correct me if I am wrong.
But, I don't think the valve seals should make a difference in oil pressure.:

No, valve stem seals should no impact oil pressure (i.e. they're in the top end). These are a known problem on 05 models. No need to replace the rings when taking off the heads. At 42K, might be a good idea. Personally, I would have the cylinder's bored to 95" and flat tops. Should be like $250-300 in parts.

I agree. I was referring to the original post.
(He is asking about oil pressure)

I have 2005 FLHT and it burns about a quart of oil every 700 to 800 miles. Have been told by numerous HD dealers that the valve guides in the 05 are bad but there is nothing HD will do. I have rode for 30 years and this is first HD and I love it but the HD company is one sorry bunch of people. I will keep this one and rebuild as I will never buy another HD. I guess that is why they now have to advertise to sell new bikes. You would think they would recall the valve guides and correct their mistake.

Take off your rocker box cover and see if the seals are black or orange.

The orange ones are much better. The black ones are the ones that fail.
