Have you checked timing? Do you have a colourtune? Have you/are you able to complete a compression check on the cylinders?

What is the WD40 test you did for a leaky inlet manifold?
Might have to try it on mine.

Could be head gasket because i have mayo in the rocker cover. But water is clear and the coolant level has not gone down.

I think that is total tosh.Hi. If you spray WD40 all around the inlet manifold and the engine revs increase at all then you have a leaky inlet manifold. It works because it is highly flammable and if it gets in the engine it raises the revs for a few seconds.

is this a regular constant missfire or an irregular one

If it was the head gasket between 2 and 3 as Dave has said you wouldn't necessarily get oil in the water or loss of water.Could be head gasket because i have mayo in the rocker cover. But water is clear and the coolant level has not gone down.
These are common symptoms of a gasket failure yes, but your syptoms are the misfire due to the pistons loosing compression to each other (this is common on the A series).
You would only lose water or get oil and water mixing if the gasket had blown between a waterway and a cylinder or between a waterway and oilway.
As for the WD40, it generally aint a good idea to do that as a test.
Have you tried a compression test on all four cylinders yet? :wink:

this will cause the revs to drop off..!
As for the WD40 I have saw this mentioned a couple times here.... don't use it.... being so flammable and spraying it around a hot engine, especially one that is mis-firing (could be an electrical short and you could have stray sparks about)
Safety first folks...!
But I agree with above, timing check then compression check...

Let us know what it was when you get it sorted!

Any idea whether these are normal figures.

no 1 is nearest the rad end.
firing order is 1342
dizzy leads should be like that (1342) starting from the top right as you look at it.
