what happens if you leave the engine to idle for 15 mins from cold with the rad cap off,, assuming its warmed up after 10 mins, does any water bubble out of the rad cap if its left to idle, is the rad filled to its max mark. who changed the HG.

Does the water level go down any, like are you loosing it? The bubbling rad sounds like you still have a head gasket prob. What was the block/head surfaces like?

A few questions:

Where did the head gasket blow (into a water cavity or between cylinders)? What is the noise that you hear, is it noisy lifters I take it? So is it backfiring through the carb you say?

Cutting out is a fuel/spark problem. Not starting afterwards sounds like fuel delivery probs and would make sense if you changed the fuel tank. Are you using the in tank fuel pump and are you sure it works fine? As you say check all plug leads but make sure you haven't nipped something between the head and block (I did that once!).

sure you have used the right clearances?

They do tap, maybe they're just set wider than they were before (i.e. correctly or incorrectly now) and with all the other problems you think it sounds a lot worse?

I know noises can appear after something else goes wrong, your always looking for stuff whereas before you just drive it!

does it run evenly?

Tappet clearances could be causing the effects you describe.

What happens if you set your valve clearance tighter than the manual says? Does it get any quieter? I'm not saying this is the solution but the rocker tips are worn on my car and they are noisy unless I set them a little tighter. Are you sure you didn't pull a lifter out of it's bore when you pulled the head? Maybe you can't do this with a 1275 but I did it once on my 998. Also are you sure your rockers aren't hitting the rocker cover, like is it quiet with the cover off?

If they are smaller than .012" they won't shut properly when the engine is hot.

Metro turbo weekend driver,Mini turbo in the making again!

Your right but at least it will show that all the lfters are in place and nothing serious is amis, I just mean to try it and not leave it like this. In reality when you set the clearances the feeler gauge goes between the valve stem and the part of the tip that doesn't wipe the valve stem. i.e the clearance might be text book at this part of the rocker but the the part of the tip that makes contact is worn and hollowed a bit there is more slack there. This sounds confusing!

The head gasket problems could be a warped head?

0.012" is to allow for the wear

jimmy hove you checked the compression ratio

also is the engine firing on all 4 spark plugs ?

by removing the leads one by one to see if the engine dies

is there anyone who lives near jimmy who could take a look ????
