Hi everyone.
So, it all started with a misfire. I checked things out and changed the wiring loom in the rocker cover area. Checked the plug for oil and also checked for oil in the wiring loom to ECU. Still had misfire. So sourced some injectors on ebay (£150, Bargin) I thought that at that price I could replace the lot of them and not have to mess on working out which one was causing me problems. I have heard that you can run engine with rocker cover off if you manufacture a guard to keep the oil in when sprayed everywhere from cam chain. (that might be my next step)
So, new copper washers fitted to new/second hand injectors and fitted back to engine. Cover back on and try to start. It did start after a bit of winding over, which I expected due to disturbing the system, And it ran perfect on all five, then coughed and petered out. Suspect that there was still air in system. Tried it again and it was like it had locked up. Repeated tries eventually turned it over where it just wound and wound with white smoke from exhaust and a metalic tink from engine.
I haven't dared take the lid off again yet. Something sounds expensive though.
To say I'm a bit ****ed off is an understatement. I was told that there wouldn't be any adjustment required by a main dealer when I got the new copper washers but now I think that I might have buggered something by not checking clearances. Any idea's as to what I'm going to find when the lid comes off?

You are supposed to check the pushrod clearance on full depression of each EUI.Its a bit late now,but either taking it apart without doing a cylinder balance test on Testbook or reading the book has probably cost you a load.How do you know if the injectors you bought were any good,the right ones - plus they are supposed to be coded into the ECU before you use them.

If one or more injector pushrods has bottomed-out because it was run up with no clearance ...... OMiGod ..... and the end result may have been a flood of fuel into a cylinder, hydraulic locking ..... disaster ......

take it to bits again, fit five injectors, new copper washers, SET THE INJECTOR ROCKER CLEARANCES and try again.

Learn the fuel system air-purge procedures before you try starting it next time.

Okay, I'm stupid. Taken the injectors out again and found no signs of any problem. Re-fitted and checked clearance. No real issues there all were within the correct setting, one full turn out after bottoming. re-fitted lid and tried to purge system as per the book. Noises from fuel tank sender pump, made a few enquiries and then checked fuel pressure, found next to nothing. So, suspect fuel tank sender unit pump arrangement to be at fault. And here still hoping that no damage was done. Can't do anything now for four months as heading back to nasty grey shippy thing. Damn the job....
Thanks for input, I guess the guy who told me I could just throw them in was giving me a duff steer. (main dealer dude, need I say more??)
