Gentlepeople,
Here is the tale.
When I got Rene ,1976 TL 875cc, the head gasket was gone due to a very knackered water pump and a stuck thermostat. I duly replaced the head gasket etc, car ran great, still used a tiny bit of water but didn't stop us from driving down to Normandy from Edinburgh and touring around in 2008. Now after laying up last year I've done all the bits and bobs for his MOT to find tonight the head gasket away again. I checked the oil, a bit above the level and very cloudy, topped up the water and checked the overflow bottle, sure enough, a bubble every few seconds, and looking at the centre head bolt ( the one outside the rocker cover with the throttle cable clamp under it) water and bubbles coming from that.
Just removed the head and the gasket doesn't have an obvious track/leak.
Now, for reasons lost in the mists of time, I didn't have the head skimmed when I relaced the gasket the first time, but I will this time!.
What's bothering me is, what are the chances of it being the bottom liner seals that are leaking?. They weren't disturbed when doing the job this time or the first time. It really seems to be a warped head that's causing the problem, but I though it would be prudent to ask your collective opinions?.
Thanks,
Alan.
PS, off to Normandy for some R4 touring again in June!!!
