I have some new cylinders which have been sat with the pistons inside. They have been taken out, cleaned and then sat around, and as they don't have machine oil on them one of them has a slight staining (think rust where moisture has sat). It mostly wipes away, it is not rough but it is stained. Do I worry about this or do something about it? If so, what? A wipe over with emery paper?
can't you use one of those honeing things i thought that cleaned bores up but i have the reputation of talking Marmite so don't quote me.
i don't know. I've been reading up, there are equal measures of for and against for honing. These are 1800 barrels taken out to 1911, so they've already been bored out and therefore, one would assume, honed too. As this will be a fresh new engine build I have to ensure that the rings seat properly during break in - will this staining affect this?
sorry then i don't want to commit, landrovers are made of stronger stuff and people don't have a go for having an opinion on there..... (no offence)
The great mucky green (laurie petite )told me they need the cross hatch so the oil can lube the rings , He also said to remove any staining or slight rust put some 320 grit wet or dry over your fist and in a Fisting turning motion simulate sex with the barrell .
'Folklore tells us BMW M10 engine blocks were also reportedly weathered in the rain and urinated on by mechanics prior to becoming 1500 HP banshees'.
I got caught a few weeks back peeing on my neighbour but one's BMW on the way home from the pub!! that's what I told him,he still doesn't talk to me
ps yes hone thecylinders with a honing tool if you have one or as above, aslo helps the rings to bed in, the rusted area will polish up and caused leaky rings and possibly siezure
