Ta Charles, Tappet chest breather pipe is clear I think. I can blow down it with no resistance. In view of your comments re removal of tappet chest covers, I'm going to leave well alone for now. Probably going to do an unleaded conversion later this year, so I can investigate the covers then. Still ...

Thanks again Vic. My standard breather setup which I have replaced with with an extension to a catch tank from the side plate pipe and joined the 2 stubs on the carbs was as you describe, except I used my own pipework and y piece. I've had a check round the front carb as far as I can without taking ...

Thanks Vic. I've just done a 15 mile run after connecting the carbs breather tubes together, and run a pipe from the side plate pipe to a catch tank. Result no smoke even after 10 minutes ticking over. Nothing in the catch tank. Very little breathings from either the filler cap or the side plate tub...

Car is a standard 1978 GT. I put the car back on the road on 1st April after a winter lay up. During the lay up I returned the engine breathing back to standard from the system that a preious owner had put in - open pipe from the side plate with a cloth filter, and the breather pipes on the hifs joi...

Just checking valve clearances, and I notice that some of the rocker pads do not line up with the vale stem ends. The out of alignment is 20 - 30 thou sideways. All the washers on the rocker shaft appear to be present. Question, are all the rockers identical, or should they have specific places on t...

Charles you wicked man. Finding me more problems to solve!! When you think about it you are correct - the pressure should push the coolant back from whence it came when it cools. My pressure cap is 15lb - not sure if this is correct. So, any more thoughts on this? Charles Farran wrote: > Dave, > > I...

Ta for the replies. No obvious leaking ploints. Tank cap holding good pressure overnight. A couple of weeks ago I spent a long time tuning the carbs, half an hour with the engine running and the electric fan coming on intermittently. It's possible that I may have lost some water then. Anyway I will ...

Did all the checks mentioned above. Turned out to be low coolant level. Expansion tank nearly empty, and level slightly down in the thermostat housing. Topped up less than half a pint in thermostat housing, and a bit more than that in the tank, and temp gauge back to normal. I'm surprised that such ...
