I forgot to ask the guy who works for a accident repair company to get black, cross fingers and hope it doesnt leak.
I did clean through the breather section on top with the four pipes connected, a lot of crap came out, also the y pipe, and the two spiggots at top back left, one wasnt to bad but the one with the pin whole seemed quite blocked, I cleaned it best I could.
I did notice that the original gaskets were quite hard and the little ring seals were breaking of as I took them out, had gone brittle.
Im not sure if I cleaned all breather sections but I did clean most of what I could get to.
As for the starting, the car did start straight away, about four times, but when I went to the shops it played up again, didnt start,waited then it did start. it didnt seem as bad but I oviously still have this problem.
I will have to find out just where the crank sensor is so if it needs changing I can do this.
I did notice also that under the fuel inlet section, the section you take off above the oil cooler head, the little push on electrical connection was loose, I tightened it,not sure what it does, the electrical lead slids onto this small roung disc.
Thanks for replying.
