Hi all. I have just finished replacing the head gasket on my 98 V70 and have a wierd issue. Upon filling the radiator tank the coolant all leaked out within an hour or two. The car had not been started - so gravity pressure only. I thought it might be the pipe which attaches to the back of the head ...

Cheers for the suggestions guys (and gals...)

I will try these out and let you know.

OK - still no luck. I think I may have to take it to a mechanic - I hate it when I have to throw in the towel! Things I have now done: New Plugs New Rotor and Distributor New Cam Position sensor New fuel pump relay new injectors new PCV system - Vacuum pipes and tank new Inlet manifold gasket (part ...

Hi all... Just an update in case it helps. I still have the issue. Have replaced the plugs, rotor, distributor, leads, coil, MAF, Cam position sensor and fuel pump relay.

OK - Yes, I have since swapped a MAF in and no difference - although it did trigger a code with no maf connected. (Good...)

I will do a compression test as it seems a common thread.

Hi all. Have been reading the threads, but so far a case of not finding anything that matches exactly so want to run some thoughts past you all to see if I am on the right track. Symptoms: Car runs extremely rough sometimes. It really only started a few days ago. I mean not a little misfire, but rea...
