Update:
- New thermostat assembly fitted.
- New water pump fitted.
- X6 sparks plugs fitted.
- Piper 270 cams fitted (with issues).
So, the Piper cams. All fitted and torqued as per the book. Went to fit the main cam belt then the primary locking tools. I can’t fit the tool to the front bank. After much checking and questioning my sanity it appears I have a duff camshaft in such that they have machined the sprocket notch in the wrong place, about 90 degrees out. I offered my original camshaft up against the new one and it is different. So I have some thinking to do to get around this.
One thing I have learned from this strip down, the cam covers mesh filters are located where the breather push fittings are, one fitting is a large hole, the other looks like a solid wall, no it is not! There is a diameter 1.5mm hole there! Mine were blocked, couldn’t see it. Could cause an issue with crankcase pressures apparently.
