Odd one this..
The old V8 has a coolant leak, it is dripping off of the bottom of the bellhousing i've removed the bell housing inspection plate and had a root around and oddly the inside of the bellhousing looks dry even the bottom feels dry if i root around with my finger, it just seems to leak coolant down the joint between the engine and the bellhousing.
The odd thing is she builds pressure in the system just fine, however if I remove the expansion tank cap and relieve all the pressure the leak stops immediately..
refit the cap and let it pressurise again and the leak returns.
My head is saying its got a headgasket leak from the coolant gallery and its weeping out when she's building pressure??
Another issue "or is it" is the coolant has a fair few big bubbles in it when shes running with the cap off, could be paranoia or is that indicative of a headgasket?
Any advice appreciated.
