why is that?it is on the topic title,I've searched a lot things on the car already,my last hope before opening the engine again is here,if someone has any idea.

without opening the expansion tank cap,and from inside the car,with switched off engine I can hear noise like air in the system.if I open the cap for at least one minute air bubbles coming out like hell.

Because you said, " I thought compression was in the coolant but no coolant missing,no overheating,no coolant in the oil."  That indicated everything is working fine.

The coolant system works under pressure, by opening the cap while engine is HOT , you release that pressure and coolant/water comes out immediately. When you put water back in and close the cap, there is air in the system which will self bleed if you don't constantly opening a hot coolant system.

Did you use 50% coolant/50% water? Sounds there is nothing to be concern.

I read it three times and I still have on idea what you're trying to say.

Shouldn't you wash the car after the road trip instead of before?

Sorry to hear about that junkyard engine. Hope it has a warranty.

Nice!

Loose pressure plate bolt is really no excuse.
