Hi all just wondering what sort of thing you'd expect when you see smoke coming out of the rear bank just underneath the intake manifold.
Definitely not exhaust as there is a strong burning smell and nothing is dripping onto the exhaust downpipe. Engine is still relatively cold and smoke starts only after having the engine on for about 4 mins. Engine is idling fine otherwise.
Have removed the thermostat as I thought it may have coolant circulating issues but water is circulating fine. Temperature gauge reads normal. I'm guessing potentially an oil circulation issue. Where is the oil pump located? In the sump? Or worst case scenario oil entering pistons.
Any thoughts?
You never get a second chance to make a first impression.
Burning coolant... hate to say it, but blown head gasket. Check the coolant level, depending on the blow, it can be chewed up really quicky or really slowly. Compression test will confirm.

normal or chocolate milk shake?
True ^^ but sometimes the gasket can blow direct between the water gallery & the cylinder, just burning the coolant.... leaving the oil ok.... othertimes, it can go to porridge.

sry, just trying to learn
Yup sometimes the blow can be almost 'cosmetic' if you will. Simply pull the head, replace gasket & torque it all back up. Mind you I'd never recommend putting a head back on unless its been serviced. Ie checked for warps & bows etc, machined if need be then had valve guides etc changed.
If you have a head gasket blow between both a water gallery & an oil gallery, the water will mix with the oil - leaving the oil looking like brown porridge & smelling like sh*t
and if u leave the problem be for a while, since u r going to keep topping up the water and the water mixes with the oil, u'll eventually end up with double or even tripple the amount "oil"/milk shake in your engine compared to what u are supposed to have.
which means u'll eventually blow other things up just because of the preasure... eventually u'll be able to track where you have been by the brown sluge trail u leave behind.
but probably not as much smoke.... until your pipes and what not start cracking under preasure.
moral of the story... if your oil looks brown, then fix it asap, and dont use a wire brush to clean the head

Is there a sure fire way to test yourself whether it's the head gasket? The car is unregistered and not yet drivable so professional compression test might be out of the question.
I just heard that if I pull the head off there's no turning back as in the head has to go to the workshop so it goes back in properly.

to be sure.... through a handful of chalk dust into your engine bay (well... more complecated than that lol, but u get the pic), and turn the car on for a while and see where the leak is coming from
