hi my i was out in the rs last week giving it a good ride out and just finished playing with a scooby and it started smoking like hell from the bonnet so i stopped and looked under the bonnet and it had blew the end cap off the end of my newley record rad.i was not happy so i took the rad back and the put it right.got home put it all back together bleed it all up again took it out and not even giving it any beans it blew a the pipe in half from the thermostat to the heater matrix yes the pipe was weak and soft but. have i got a blown head gasket thats pressurising the collant system??? theres no sighns of oil in the water or water in the oil????? help please

Hi there. Any type of liquid mixing together isn't a good sign. Is the any history of the car having any previous work done to the engine.

hi there is no sighns of liqiuds mixing at all.and the car has had a engine rebuild with alot of work done but that was about 5k ago apart from that its always been a reliable car tbh im thinking do i just do the head gasket and full set of samcos and go from there?

Try taking your thermostat out for an inspection, mine kept doing this and then realise te stat had s**t itself inside the housing blocking the flow and this increasing the pressure . Defo worth a check, best thin to do for the head gasket is either have it conpression tested or a dip test. Easy DIY ways are checking oil for mixture check water for same and sniff the header tank for smell of petrol . If you get none of these the engine doesn't smoke and runs fine I highly doubt it will be the gasket to blame. A good inspection of all your water hoses for splits etc will be a good start too.

Agreed to Russ.Also,keep in mind that the hoses may be aged and perished.If you rev it at 2500-3000RPM does the water in the expansion tank rise?I mean it must be,but not too much.Also,check for bubbles in the expansion tank when you rev it.Bubbles are no good sign.Also something last.It is not necessary for the fluids to mix together.There are chances that the hg has blown between the cylinder and the water jacket,not between the oil gallery and water jacket.Although if it didn;t had the time to overheat,I doubt it will blow the hg.Wishing you not to had damage,and just be the aged hoses...
