Week 22 - The Build

 Finished getting the cam timing job done. All I needed was a new bolt to hold the crankshaft pullies on. That arrived the next day so spent a few hours checking I'd got everything lined up then tightened the bolt. By tight, the book says 100Nm then 90 degrees more then 15 degrees after that. That is very tight, in fact about as far as I could tighten it with a long breaker bar on the 18mm socket.

After removing the flywheel locking tool I checked the cam timing againa couple of times and that the engine freely rotated 360 degrees. All good so fitted all the covers, water pump pulley, alternator and stretchy belt. 

Next job is to get the engine back in the hull. After quite a lot of practice over the last few weeks it went in quite easily. Connected up the drive shafts, fuel line, engine earth, and the two electronic plugs and ... 

it still wont start! The OBD reports the camshaft position sensors are open circuit. Hard to believe that both have failed. I'm convinced it's the extension to the wiring loom that I did back in December 2019. On examining the 80 or so electrical connections I saw that some didnt seem that great and others seemed quite poor. I remade all those with solder and heat shrink. Plugged everything back in and ,,,,

it still wont start! The OBD still reports the cam sensors open circuit and so for a tenner each I replaced them with new ones. You can guess what happened next.

Still convinced its my wiring I decide to remove the cables in their conduit from the channel in the hull and remove the split conduit and just check the cables over. Straight away I could see there were a number of cables joined along their length. One of these had come adrift and another looking pooly. Without hesitation I quickly rejoined with solder the one that had come apart. Connected everything back up and ...

 

 

Very pleasing. A significant milestone here. I can now progress with pretty much any other part of the build.

In light of this I shall set about resoldering a lot more connections! A new soldering iron is enroute that should deal with the thicker wires required.
