Engine Cooling problem
1997 BMW 318 4 cyl Two Wheel Drive Automatic 165000 miles
----------------------------------------------------------------
Hi, While driving my temperature gage hit the roof, vehicle started making metal on metal sounds and steaming heavily from behind the rocket cover looks like a burst pipe.
Vechicle runs fine once cooled but only until it heats up then same happens again.

Oil is fine and water in radiator is fine. Radiator pipe when squeezed expels steam from rear of rocket cover.

Unsure how major it is, i am not driving it at the moment until i get it fixed, but am worried how much it may cost.

Any ideas

You may have cracked the cylinder head. This could be expensive.
