Ablock of wood is no good, your measuring very fine tolerances and should be measured with an engineering/machined straight edge and feeler gauges.

sorry i havnt explained properly....Originally Posted by Tony Walker
Iv trial fitted the liners without seals, using a block of wood on top of them to not damge them iv taped them down, but if i tap them down fairly hard, i get no liner protrusion. I measure this with a metal rule, and feeler gauges. I only use the block of wood to lay over top of liners and tap on block to seast the liners
how low do they sit?
cleaned up where liner sits today and liners abit, put them all in where they came from without seals and tapped them all home and flat.
no1 nearest flywheel protrusion - 0.002/0.003
no2 - 0.004
no3 - 0.004
no4 - 0.002/0.003
Haynes manual says they should be stepped down so that the liner with the least protrusion is no4?
Well i have liner protrusion so im thinking im just going to order new bits and go for it. List i have so far is
have crank checked
new piston rings
hoon liners
thrust washers
big end shells
main shells
oil pump refurb kit/new oil pump? is the refurb kit ok to fit?
new gasket set bottom end and head, blue hg, high tensile bolts
and obviously coolant, oil, filter
head checked - done
anything iv missed?
when refurbing the oil pump you'll find the face that bolts to the housing and contains the pump internals will be worn with scoring marks, get this machined flat or, with some fine sandpaper a little oil and a machined flat surface hold the housing flat on to it and work it round keeping the housing flat.
FOUND PROBLEM
Well just out in garage cleaning bits and getting list together of seals i need etc, thought id have a closer look at corrosion on liners, wire brushed the outside on the corrosion marks, put some brake cleaner there and it leaked through to inside. BINGO!
you can just see the corrosion in this pic below
In put on liners please guys? 2 out of 4 look pretty corroded but im thinking just replace them all. The options available are 4 new liners from cgb, or i have a spare block here which had new liners in when it was built, its been sat so therel need a hone, but providing they clean up ok am i ok to use with my pistons (new rings will be fitted) and what do i do just arrange them in order like it says in haynes?? cheers
so glad iv found the actual problem, or would of rebuilt for it to still be leeking
ive got 4 liners here if ya interested they will need a slight hone out
Got a brand new set of 4 tarabusi liners sittin here.. give me a pm if interested. also liner seals brand new with them
