V8david Posted May 22, 2008 Share Posted May 22, 2008 Really sorry about this everyone, stupid question time... I took my cylinder heads to be skimmed, while they had them they took the valves out and seated them. Beautiful job, but.. I've got all the valves in two boxes, numbered for the right places/head etc. Now cos I didn't take them apart I don't know where the inlet valve stem oil seals go (told you it was a stupid question). Where do they fit in relation to the collets for example? Basically where the bloody hell on the valve stem do they fit?! Worded instruction would be nice but a picture would be excellent! I've checked the LR parts pictures and I can see the buggers but not where they go! Cheers Quote Link to comment Share on other sites More sharing options...
Bull Bar Cowboy Posted May 23, 2008 Share Posted May 23, 2008 Which Type ? The early type (up to 94) just slide onto the valve stem of the inlet valves only. They have no actual position and usually end up sitting just under the the spring cap. They are just like a rubber washer about the same diameter as a 10p piece. The later hooded type are fitted over the top of the valve guide and are fitted on both inlet & exhaust valves. These were used after about 1994 ........ You cannot use the later type seals on early heads unless you have the tops of the guides machined to accept the 'hood'. Ian Quote Link to comment Share on other sites More sharing options...
V8david Posted May 23, 2008 Author Share Posted May 23, 2008 Thanks Ian, much appreciated. They're the early type. I've got 8 new ones as the old ones are either cracked or broken, or both. When you say they "end up" sitting just below the spring cap, do you mean that anywhere on the valve stem below that is acceptable? As eventually they will all end up moving up anyway. I've read in my V8 book about the later hooded type, very interesting read. The whole book that is, not just about the valve seals...

Bull Bar Cowboy Posted May 25, 2008 Share Posted May 25, 2008 Yes, just slide it onto the stem of the inlet valve ................ it was find its own resting place........... Ian Quote Link to comment Share on other sites More sharing options...
alfredenewman Posted May 30, 2008 Share Posted May 30, 2008 slide them down as far as you can when the valve opens it will slide up to it best position directly above the guide. Quote Link to comment Share on other sites More sharing options...
