Oh wow no mine is the one on the right, and after some more research and measurements I'm sure it's a 160. Thanks for the pics though that's interesting to know
I'm planning on shaving the head today, I'm just gonna get the belt sander out I think. I know it bodgy but I have heaps of 1.8 mm gasket paper and I'm not paying for thinner stuff when I've got over a square metre of the 1.8, besides I figure if the head is a bit out of square the 1.8mm paper will squash down a bit and keep it sealed anyway.
Does anyone know how much I should be taking of, I was think of filling the decompressor port with weld and taking 3-3.5mm off the head. the 1.8 gasket paper should add about 1.2mm anyway, if guess is correct.
Does anyone know the standard compression of these engines and how much each mm changes it.
Also I've pulled the piston out and I'm thinking of getting new rings but there's a few things I'm unsure of.
1: does the block need to be honed
2: do I need a piston or just rings
3: how do I know how far oversize the rings should be, it looks as if it's had a fair bit of use and one side of the piston was black from what I assume to be combustion slipping past the rings
3: also the entire engine block is covered in a mix of rust, dirt and general filth what the best way to clean this. Plan on having the head shiny and the block painted red, yellow or blue
