time for reman heads?
Think I have some bad valve guides which are allowing oil to leak into the cylinders when I'm shut down. I don't think all of them are bad just a couple. Is replacing the guides doable or should I just invest in some new heads. Looks like $350 per head plus head gaskets.

I'm pretty sure it is oil cause the smoke is white. It could be injector o-rings, but I have a feeling it is valve guides because depending on what valves close on shutdown, depends on if oil leaks into the cylinders. Enough blab, I want to replace the valve guides. I'm trying to see if I should get new heads, or just replace the valve guides in the heads I have. I wouldn't mind having new valve springs and valves.

White smoke can be unburnt fuel which normally happens on cold startups. White smoke can also be oil, just like a gasser. I'm loosing oil so I'm pretty sure about the oil leaking into the cylinders either through leaky valve guides or by the injector o-rings or injector cups. I don't want this to turn into a cold start thread. What I want to know is, has anyone replaced or rebuilt their cylinder heads and if so, is their a cost advantage either way.

Well.. not sure about what exactly the cause is with this one, but as for the heads issues with new valve guides, it can be done, and not overly expensive. I was in a machine shop not long ago, and got to see the work on a set of 7.3 heads getting new guides. So, I know that work can be completed. As for price, may have to check around!

I figured that I wasn't the only person wanting to have this done. Midwest, did you happen to ask why he was getting new valve guides. I'm wondering if it was cause of oil leaking into the cylinders. As far as the valve guides, I think I want to go with bronze guides. The only problem is determining whether to get thin walled or thick walled. Anyone have an opinion?

That's the thing. If I take the heads off to do the valve guides I might as well get new valve springs and get new valves. The only type of valve work I've done is on a 8hp Briggs and Stratton. We used valve grinding compound and blue check. I'm sure a good valve job would be better than that? My buddy is always talking about this 3 angle valve job

Ive often heard that the valve springs are the weakest link in the whole motor so if its within reason there are some pro comp springs with about 10psi more than OEM strength to them for about $80 on ebay.I believe the pn is a 910-60.

The ones you are talking are Comp Cam 910-16. And you are correct. If your doing springs, Might as well do it with those
