I appear to be getting a reasonable amount of smelly gunk in my catch tank, the amount in the glass shown has been over the last few weeks and about 300 miles. My question is, Is this normal?

Good afternoon chaps

Doesn't look right to me, looks like it might have some coolant in with the oil to give it the milky appearance.
Might be worth checking what the plugs look like to see if the colour is what you'd expect it to be.
Mmmmmmm tasty 
Looks like emulsified oil to me (oil mixed with water)
Its quite possible that its just oil mixing with water in the breather system and ending up as mayo in the tank.
But the question is if that's the only place your finding it?
Is the loads of the same stuff inside the oil filler cap or on the dipstick?
Also what engine is it? Some breathe heavier than others... but it does look like quite alot to me

What temperature is the engine running at ?
Cheers for the replies guys.
Engine is a 2.0 silvertop unmodified running jenvey tb
No sign of emulsification on either the dipstick or oil filler cap
Engine temp is actually quite low, 80 while running about maybe 90 in traffic
Looks similar to mine to be honest. Condensation mixed with oil makes it Mayo like. I wouldn't worry about it.
Condensation is a possibility, but it does seem quite a bit to have "breathed" out of the engine over a short distance.
Some years ago now, but we used to find GTX would get condensation problems on Fords. However I would be worried about a head gasket problem here. Maybe a compression test and a coolant pressure test too. Also a friendly MoT man might use an exhaust probe to 'sniff' for combustion gases in your header tank.

and my crossflow, for the first couple of runs of the season, but it normally clears up with an oil change and use

80c at the cylinder head outlet is too cold, these engines were designed to run at around 100c, a properly working thermostat with enough by-pass circulation to keep the lower half of the engine in the high 80's.

Cheers for the replies lads. I did think it was running a bit cool to be honest so I'll check the stat.
