dieseldoc Posted June 28, 2007 Share Posted June 28, 2007 Working on a 94 DIT 7.3, the pick-up has 250,000 mi.on it. Has a leaking intake valve. I Have a machine shop that will do the head work for me(dont have the tooling to do it myself in my shop). I have a couple questions though. Can you plane the heads, if they need it? Should I put new injector sleeves in now as preventive maintenance? The bottom end of this engine doesnt show any signs of wear really. I think it will run many more miles once the heads have been gone through. Any input is greatly appreciated, thanks in advance guys. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted June 28, 2007 Share Posted June 28, 2007 According to the manual Quote: Using a straightedge and a 0.15mm (0.006-inch) feeler gauge, check cylinder head gasket surface for warpage horizontally, diagonally and transversely. Check cylinder block deck for flatness in the same manner. Cylinder heads cannot be resurfaced. Replace cylinder head if it is cracked or warped. As for the injector cups, ABSOLUTELY!

DwayneGorniak Posted June 28, 2007 Share Posted June 28, 2007 they say you can't machine the heads because there is only .006" to play with and you may touch the valves if the heads are machined to much. But a buddy of mine that owns a machine shop says he can machine the heads. He just has to recess the valves deaper into the heads. Just what I've been told.

Bruce Amacker Posted June 28, 2007 Share Posted June 28, 2007 Too bad you're not closer to me. I have two brand new '94-95 PSD heads (never run) without valves that I could let go cheap.... Quote Link to comment Share on other sites More sharing options...
dieseldoc Posted June 29, 2007 Author Share Posted June 29, 2007 Thanks guys I knew I read that somewhere before. I havent had a chance to check them for straightness yet. So it may not be an issue, but I had a customer of mine ask me also. Say bruce what do you mean by cheap? Do they have guides and seats, so they just need valves? I would be willing to pay shipping if the price was right. Thanks again for the info guys. Quote Link to comment Share on other sites More sharing options...

I would be willing to pay shipping if the price was right. Thanks again for the info guys. Yes, I believe they have guides and seats. I bought a brand new PSD with a broken block years ago that was ravaged for parts, so someone had taken everything off the heads that could unbolt. $100 for the pair sound too high? They weigh a ton, I don't know how to ship then cheaply. If you can deal with the time, call me at 440-846-3885 and I'll look them over and shoot some pics tomorrow. I still have the block, too, and the only thing wrong with it is the bolt holes are screwed up where the FP mounts from someone running too long of a bolt into the bosses. The side of the boss is blown out on 1 or both, I don't remember. I just scrapped the brand new CS a few weeks ago 'cause I thought I'd never need it.
