Re: WBXOily
Thanks I use this which is far easier because it's illustrated and more trustworthy because it's a VW publication.
I haven't checked valve diameters, just the play page 15.18

Re: WBXOily
Yep just tried this on an old head, gently heat combustion chamber with blow lamp to expand the bore squirt wd 40 through the tube onto the fire ring to shrink and out it will pop, well mine did and it was stuck before, good luck.

Re: WBXOily
That should work - you can also try a feeler gauge instead of a screwdriver.

Thanks weimarbus heat worked but I didn't need to spray it.
I heated the ring by going round in circles with the torch, the ring expanded and buckled lifting in one place than easy to lift out
Not a scratch in sight.

Everything is easy when you know how, it wasn't immediately obvious to me and I have done quite a few head seals in the past.
Its why I try to share what I have learned, I bet others have strugged with this too.

Re: WBXOily
There's not much point in getting older if you don't hopefully get a little wiser. The last time I thought 'it's only a little scratch' it led to pressurising the coolant around 10,000 miles later and scrapped heads.

Re: WBXOily
Cleaned up head 1&2 today and ground valves, inlet for No2 would not grind it's had it, burnt by the looks, maybe lean the deposits were rock hard, found a good valve from a scrap head and swapped it over.
so that explains low compression on No2
No1 10 bar ( leaking oil out of plug hole)
No2 8,75 bar ( worn inlet valve)
No3 9 bar ( broken rings)
No4 11 bar

Re: WBXOily
Have you any pics of the worn valve and seat?
Why would the glass be anything other than half full?

Re: WBXOily
I decided to swap both inlet valves as I wasn't happy with the other either.
Valves refitted.
P1090033 by Paul_Barr, on Flickr
The inlet valves on the other are just as bad so I didin't even bother trying to grind them, I just swapped them with some from another head.

Re: WBXOily
I really want this out of the shed before the camping season starts so need to crack on.
I need a parts list as it's not my engine so I want all the bits ordered
End float is way too much so removed the flywheel to see whats happening
P1090517 by Paul_Barr, on Flickr
quite oily not helped by the usual groove in the flywheel
P1090518 by Paul_Barr, on Flickr
I like to cut the lip off the seal so I can see what I'm doing
P1090519 by Paul_Barr, on Flickr
punch the seal in a few places taking care not to slip off, it releases it
P1090521 by Paul_Barr, on Flickr
lever it out
P1090523 by Paul_Barr, on Flickr
looks reasonable, no disasters
P1090524 by Paul_Barr, on Flickr
large shim should be 0.4mm this is where most of the wear is
P1090526 by Paul_Barr, on Flickr
other two are both 0.37mm
I had a new 0.4 'in stock' so tried it
o ring out first
P1090525 by Paul_Barr, on Flickr
gone too far 0.02mm ( want 0.07 to 0.1mm ideally, lower end of the range)
P1090529 by Paul_Barr, on Flickr
swapped a 0.37 with a 0.32 I had 'in stock'
thats good
