Hi,
We've got an old Coltri believed to be an MCH8 that from a previous thread on here I see it's really and MCH11 with a slower motor on it potentially?
Had an issue with too much oil the filter stack and taking off the 1st head revealed a fair bit of oil on top of the piston enough to coat your finger, I realise there will be some oil but seems excessive.
Removing the cylinder revealed no gasket in place between the block and the cylinder is this normal? we notice some potential oil leak around there too.
Not sure when or if the piston rings have ever been changed but on this age of compressor around 1986 not having much luck.
Any help especially UK based.
Coltri have said they'd like the compressor for their museum and will offer a discount on a new one but ideally need to get this one working for under £500
Thanks.
