tried with the stick in a drill (dewalt forward n reverse) but couldnt keep the sucker in place
theres a grey band round the valve and seat now but it doesnt go from corner to corner, if you get my meaning (if you look at the valve side on there an edge at 90 degrees to the face, then theres about a 45deg angle then thats the bit that sits on the head)
the grey band doesnt go RIGHT to the 45 deg angle, just slightly below it
is that ok
and should i do them all again with the fine stuff now ?
ive been spinning them like almost 360 degrees when turning that stick
lifting them out puttin more paste on then doing it more
then ive cleaned all the paste off and took the valves out the head
theyre not supposed to be left 'in position' sort of thing are they ?
nowt wrong with turning them 360, thats what i do. the dull grey ring doesnt go right to the rim of the valve head, just aslong as its about 2mm wide, with a matching 2mm wide dull grey ring on the head, and both are perfectly cicle, the dull gray ring has a clean sharp edge, no little dings encrouching into it, no burnt bits or slighly wavey edge where lapping hasnt quite removed enough material
bloody hell lol
has took me all day (with smokebreaks off course) to do them all just with the rough paste
gonna do the rest with fine now and just clean the paste up when theyre all finished
took ages with the rough cos had to keep cleaning them until i got used to it - to see if they were done
think they looked lapped in well enuf and in ok condition ?
the picture with the 2 valves has a gasket and a washer that were in the gasket set - what are these for ?? cant remember either of them falling out when i took it to bits
yeah that lapping looks like a top job, did you do a quick go with the fine paste ?
those two gaskets - the rubber one is the thermostat housing to block seal, the copper one is a notorious head scratcher with 20XE gasket kits. not even d-ck at SBD knew what it is. thats if its the rounded one.
