The update is i went to the mechanic a day ago and he checked for the gasket leakage symptoms again and said that the gasket needs to be replaced he's the same mechanic who first said gasket is good to go after radiator was replaced.
Today he opened the head and after checking the gasket and head he said that the head is unusable because it is corroded from several places also he showed me two hairline cracks on it. Now the kabli head was going to cost me 12-15k and i didn't have that much budget plus i didn't wanted to spend this much on it plus he stated that it cannot be faced anymore as it has already been faced two times so he stated that he can do a jugar by applying magic depoxi steel and this would be good to go for about a year.
Also i got the Water body replaced the hose pipe with it (one of the main culprit behind all this because it was totally corroded and choked from inside with rust. Timing and generator belt and timing bearing.
After fitting the oil on the dipstick was a bit milkish which was 100% OK because i checked it in the morning it was totally in it's pure form and previously the oil and water was not mixing up at all just a small amount of water was burning, he said this happens after every gasket change and the oil will be cleaned after some running he also asked me to come again after two days he will tighten the head a bit more and some settings on carburetor.
