Easiest way to check head gasket?

As above, have feeling the head gasket may be gone, she'll heat now and again, not too often. she not mixin oil and water and compression is grand? what'd be the easiest way to check?? thanks

get a sniffer test done on it, if ya know someone
with a sniffer kit?

i don't, i know that way but trying to find someone with it is another story, cheers anyway. ;)

yep as mark says, but you can also check ur thermostat to see is that working , its easy and dosent cost any money

Your rad prob blocked or dead fan...Both do lead to H.G failure...
Take car for a run...feel top rad pipe...If its solid and its pumping water into expansion bottle you H.G is shagged
