Here are the spark plugs, oil on them but no signs of being steam cleaned.

If there is that much ‘air’ getting in then the sniff test would surely react if the gases were exhaust.

Thanks for the replys. When you say sniff test is that the same as the chemical block tester? Tube in the expansion tank cap hole, filled with the special liquid that you suck air into? |

Just ran a compression test on all cylinders but the 1 with the stripped coil bolt. Only thing is I did the test with the engine cold. Being I removed all the plugs last night.

Yes a basic sniff test is using the chemical like the attached which i think you have already done, this isn't a definitive answer as your head gasket or block may only be leaking under pressure or high revs. I think garages have more sophisticated gas analysers. Compression test is good for the 7 you can check.

What do you think about putting compressed air striaght into the cylinders, piston top dead center on its compression stroke. If there's a head leak it should make bubbles in the expansion tank. |

Regarding the engine you could google M62TUB44 and see if your engine looks like it, I know a bit about the BMW and nothing about the Jag.
