Bit of an odd problem.


I had some work done recently and this resulted in having to refill the coolant system and bleed it, I did this without too much hassle making sure the car was level, filled it slowly making sure that the clear pipes connected at the from of the car were both full of fluid.



Once bled I closed all the taps and all seemed well.



After driving for a short distance I could hear air/rushing water throughout heater matrix




I have checked for leaks as best as I can round he heater matrix, no wet carpets etc, and also pressure tested the system up to 1.4bar and it holds quite nicely, I cannot see any leaks either but every time I bleed the system in no time at all it's blowing bubbles and if left for long enough it stops blowing hot air thought the vents so the level is going down.



Could I be looking at a cracked block? I have checked and there is no muck in the oil filler cap and it never runs any hotter than just below the half way mark, is it drawing air in from somewhere?


Any advice would be appreciated, before I make a trip to a specialist.

Will
