I had another check today and I felt the core plugs again and one of them is raised, I could only feel 3 - is there 3 or 4 on the Golf? Two are recessed by about 3mm and the one nearest cyl. 4 is just above flush.
What should I do exactly, remove the core plug and refit a new one, or can I just try to tap it back into place (albeit extemely tight), or could I just leave it as long as its not leaking?
Also, when removing the metal cooling pipe I managed to damage a wire. I've resoldered the wire today, but the car won't start, there appears to be no fuel pressure. I was having trouble with this a few weeks ago, but after replacing some grounds for the fuel pumps - all was well. The car has been stationary for 4 weeks without being started, so this has probably had some knock on effect.
If my wire fix is not up to scratch - what is the implication of it being broken - could this cause my fuel pressure issue? Then one in question is the one which connects to the fuel regulator (?) on the block itself, featured just above the oil cooler in the photo below...
