I broke the engine with totally new internals and now its working fine .i had some problems regarding turbo all is fixed car performance is much better than it was before , it has elevate software elevate dp and exaughst.

I have a problem coolant water after i go for a trip like 40 km goes down and i get a warning in red regarding coolant , i check radiator hoses and im 100% sure there is no leaks as all the hoses and clams all are new , new thermostate assembly and new water bump .

I belive its a problem with my cylinder head , cause yesterday i see oil level is higher than normal which indicates water gets to OIL!!!,!,!,!, Now i am deassembling the cyl head , should i change the cyl head to new one or , give to workshop to fix cylinder head . If i fix my cyl head with workshop , will that affect the car performance as my mechanic said ??

my guesses are 1) head gasket, or 2) cracked sleeve, neither are good news for you

Is your oil a milky color?

My guess is that if you had all that stuff taken apart, the head gasket is most likely. I don't know what happened that you had to rebuild the engine though. Did your machinist do anything to the cylinders? He might have been too aggressive with re-honing the sleeves, and that could have caused a failure there. If not, the head gasket probably didn't seat properly & you're leaking there.

Actually , i did the rebuild because of coolant leak that leaded to exccessive heat before . I changed all the internals and fixed two cylinder sleves and installed new pistons, con rods, big end bearings , main bearings , water bump, thermostate assembly , new cam shaft seas , ew cranck shaft seals front and rare + used cylinder head

But for the setup i bought a used cylinder head , even gasket where new genuine .
