Quick update.
That it ran good the other day for a minute or two on cold start up might have been a conincedence, as starting it up yesterday the symptoms started right away. Car does not have a problem starting, starts first time, everytime.
In case it is a headgasket problem I drove it up to my grandads last light with my mum behind me, at dusk so she could tell me how excessive the smoke is. During the whole journey around 8 miles, she said 0 smoke, nothing at all.
Driving up was not a pleasure, as before lack of power, stepping on the throttle more than 1/4 down the car would start shaking aaround, engine sound changing to the more tractory sound, tock....tock...tock..tock,tocktock. Keeping the speed constant (30ish mph) 2k rev it was drivable without the vibrations and noise, going up hill sounds come back.
Does somehow seem like a lack of fuel, or mixture issues. CHecked the timing again that is ok, as is the ignition timing which is spot on at 2.5k, on the diamond, blkue snsor disconnected.
Will be up my grandads on wednesday to check things like maf, injector seating, fuel delivery. Fuel pump primes like normal and the pump in the boot hums, so pumps seem to be working fine. FUel filter was changed around 2 years ago.
Can somebody say, that this could still be a headgasket or head issue? No smoke on the whole journey last night, but I find there is a lot of white smoke pouring out when I am idling after turning it on, for at least 20-30 minutes later, like on the video. Compression results on the other hand were amazing, but I have read that that doesn't rule it out. Cant see any water in oil, no oil in water, no bummbles in expansion tank either.
Will write again wednesday If I find anything.
Thanks again guys.
