Stamford’s ZS180

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.

Have you got an idea of location (picture or whatnot) of those breather holes? When I have got T16 on the road, its on to FE54 to ger her back running again!

I’ll check which ones and let you know Sam.

Well the last two days were very productive. With the cam issues I decided to remove the cam covers as was not convinced by the problems encountered. To cut a long story short I was either tired or I failed to check the contents of each box but I had the cams in the wrong position on the front bank. After checking each set and happy with layout I rebuilt the cam carriers. I can honestly say that the cam belt service is probably the worst I have done. Not user friendly, the secondary set-up is a right pita. I would go to say it would be easier with the engine out. It is now slowly going back together. Cranked it over by hand, no dramas and everything lined up again. Just a case of trying to torque the crank pulley bolt up with no flywheel locking pin. Even in gear and wheels chocked I can still move the car! Guess it’ll have to wait until the brakes have been bled then get a helper to stand on them. Now to get the fuel filter changed, tidy up the loom then rebuild the manifolds and plenum.
