Post Subject: Problem Starting BMC 1.5 Diesel EngineHi Tony Many thanks for the quick response. With regards to your queries, please let me try to explain this more clearer. I was meaning the Injection Pump seems to have oil mixed in with the diesel inside it. The reason I found this out was due to it being recommended by Gee Diesel (The people who reconditioned the Injection Pump) it was recommended I take the Inspection Plate off to find the letter 'A' on the driveshaft inside to tell me which port on the pump was No. 1. Whilst doing this, I found what seems to be oil mixed with the diesel. After the Pump was fully reconditioned, a friend of a friend tried to fit this pump onto the engine. Whilst doing so, he didnt mesh the gears properly, proceeded to tighten the three nuts and snapped off the lug on the pump with the timing mark on it. I am wondering if he had pressed the shaft into the pump would he damage anything? i.e a seal behind the shaft that could let oil into the pump. To let you understand, diesels are not my forte but I have worked on motorcycles and cars for many years. You asked how I set the timing. By removing the timing case cover, cranking the engine until the valve timing marks line up with each other then fitting the Injection Pump Driving Spindle, locating it at 7 o'clock position, it then turns and ends up at 5 o' clock position. As I say it just so happens, the lug that is broken off the diesel pump, is the on with the timing mark on it so to remedy this, I have measured the slot on the opposite lug, scribed a centre line and also done the same on the flange. I have heard that you should do this procedure with a timing tool -18G629. I belive this is to take the slack up on the timing chain whilst refitting the drive spindle. You mentioned the small 8mm screw on the side of the top of the diesel pump - Yes I did think that was a bleed screw and I have been screwing the 8mm headed bolt in and out and I have maybe also turned the nut that this bolt this secures into. There is also two hexagon nuts on the top of the throttle body 3/8 in size with little head on top. These may also have been turned slightly. You mentioned a broken spring in the filter head - Is this on the retunr side of the head or is this on the opposite side where there is a banjo bolt? I hope I have explained as much as I can and your help and time is much appreciated on this Tony. Many thanks Rab
