latte coloured oil

[andym]

And about the same consitency from what I noticed. That's what I get for starting the bike while frozen

Silly question though, would 3/4 - 1 mile at absolute maximum 3k rpm be enough to churn up all the oil, as there isn't even a streak of dark that I noticed.

Anyway, I've decided that I can't have 2 bikes with fucked up engines, so I've decided I'm going to scrap the gpz.... just not sure what the value is selling it to a bike breaker (I know I got £150 for my mondeo to a car breaker, so I'm guessing about £50 if I'm lucky?)

Temperature is unlikely to change your oil colour, though it will of course make it thicker.

Creamier coloured oil usually means the head gasket has gone. If it a water cooled bike?

Break it yourself until you get the money you want, then weigh the rest in?

Obviously didn't pay attention at the back....

Oil can emulsify if you just do short runs in damp weather. My car used to do it as it only did 3 miles to work and back, but after a longer run at the weekend, it would be back to normal.

I pulled some oil out of the engine today.... and tried heating some of it for a few minutes:

No it isn't baileys and kahlua:

Now would I be right in thinking that the oil would be warmed up naturally by the engine to boil off the water (in a sense), and if so would I not be able to just do that on the cooker (since both engines need flushed out anyway and would mean only buying 10 litres of oil rather than 20 (well 16 really)

[goodlifefarm]

First of all, you need to establish the cause of the emulsified oil. Has it used any water from the radiator or expansion bottle? If not, Just change the oil and then take it for a long run to vaporise any water which may still be in the crankcase & sump. If it has used some water, fix that before changing the oil.

Heads can become porous over time. Could be many causes, but if it hasn't used any water, I wouldn't worry too much.

[jimspeed]

could even be the water pump seal letting water into the sump too, I would start by checking the coolant level first and go from there.
possibly a core plug as Pete says if it has been frozen up.

It froze and cracked the 'stat housing?

Ill guess its a core plug. Its what they are there for.

Damn... thought I might have got away with the oil as a flush.... oh well. The thing I'm wondering about with the core plug is they are screwed in, so not sure they would go that easily.

Oil cooler is a seperate rad. I'll get the valve cover off tomorrow and see what it's like in there, then I'll start looking elsewhere for the problem.

I should be getting the shims for the zxr tomorrow, so hopefully that can go back together, even though I've managed to shave the shims down to .01mm of the recommended sizes... so I might just send the new ones back.

Hopefully it won't be too cold (supposed to be sunny and 8-9 degrees), so I'll get a good few hours on both hopefully
