I was tasked with getting this thing back up and running this morning, so for those that find mechanical things interesting I snapped a couple of pictures. First a couple of things to make the pictures make sense.
These engines have neither timing marks or keyways, the cam and crank sprockets spin freely when the securing bolts are loosened. Service tools are used to lock the crank and cams in position to set the timing, once set the bolts are torqued. This allows the timing to be continuously reset as the chain wears.
There is no removable timing chain cover, the sprocket, chain and guide/tensioner rails are lowered in from the top and the rail assembly is secured using shouldered through bolts from the front.
This is the remains of the offending top chain guide
and wedged down in between the chain runs are the remains
A pin is used through the bell housing into the flex plate to lock the crank with the pistons half way down the bores. Then two locking plates are used to hold the cams in position. These should fit against the surface of the head and bolt together.
You can see here just how far out the exhaust cam is, impressive that I drove this car into the workshop after a spirited road test.
Out with the old bits
In with the new, timed up and ready to go
The plugs are suffering from some fuel fouling but a quick road test confirmed the repair and the fault codes cleared.
