Thread: 1954 Royal Review 47160049

I thought the bracket should be tig welded on to the plate first . I think he is going to screan print the crown on not do a contact sticker I'll try to find out more about how he is going to do it. I was just thinking about doing umbrella seals on Landy inlets also. Wayne

My inlet valve guides have been sleeved thus covering the o ring groove. I have bought a tool to cut the OD of the guide back to .530" to enable me to fit a cup type seal that fits over the guide. A more modern system and allows seals to be renewed without taking off the head.

Just thought , doesn't the valve stem seals go inside the valve caps . It's been over 20 years since i did mine , i'll check when i strip the head today Wayne

Yes the early ones went inside the caps then they changed to the o ring inside the guide which was better but you have to remove the valve to change them and be careful the valve does not cut the o ring when you insert it.
Those early ones with the seal at the top were next to useless so they say. I have never seen one.

When this tool and seal arrives I will give a demo on here and see how it goes. I hope they are not too efficient and starve the stems of oil

I will work the bracket out. Perhaps use epoxy.

I stand corrected , mine has the "O" rings in the guides , too long since I overhauled the motor . My "O" rings had turned to carbon & broken up into about 20 pieces each. BMC used "O" rings in the valve caps , they worked well , you compressed the valve spring then fitted the "O" ring on the stem then fitted the collets & released the spring compressor. This prevented the oil from runing down the center of the valve cap & it ran over the side & there was enough oil vapor around to lube the valve stem. When we did valve grinds the "O" rings were always in one piece . I think my back & ribs are broken after leaning over the guard all afternoon lapping in exhaust valves. Just have to refit exhaust collets on Monday when i.am fresh , not a good job to do when tired & saw back & refit the head . Doing a couple of other jobs while the heads off & there is a bit more room, like getting the choke light working. Yes some good epoxy glue should do the trick. I'll get the L/R going first then start on the crowns.

Well here it is, came this morning. After fixing the brakes on the 6x6 I got into this.

Was it the booster? Those seals look good do they fit inside the inner valve springs. Wayne

No not the booster. I started with the back wheels and on the last one found both bonded linings had parted from the shoes

Yes seals fit inside the springs.
