Thanks to your post Del I finally looked up in the owners manual what the factory tyre pressures should be and it is 2.5 bar (36 psi). So oops I have added to my tyre wear because I was running 34 psi as that is what the wheel alignment sticker on the windscreen said. I've also being running 4 people up a fair bit and as my kids are pretty much adults that is really 4 up, so running 2 psi low would have increased the rear tyre temp a lot.
So 36 psi all around from now on. I've removed that wheel alignment sticker!
I can also see now why many bang on about 156's being FWD and how that is a shame. When you drive the car it is not an issue at all and it is an awesome mile eater (in fact since it's oil & filter change yesterday I've already slapped another 150km's on her running my daughter around
) but the limited tyre mileage is all caused by setting up a FWD chassis to handle as an Alfa Romeo should. I'm sure, and hope, the 75/Milano chassis gets considerably better tyre mileage and running that running gear under the FAR better looking 156 body would have been awesome with all independent (FIAT?) suspension, especially if some extra attention was given to the gear change.
Anyway it is what it is and I still enjoy the car.
It does have a couple of minor oil leaks; one from the power steering pump (not long ago I resealed our Honda one and that was easy so should just do this!), and also from the rear of the engine. I'm currently assuming a slight rear crank seal leak ... Thanks to the under tray it never drips on the garage floor
One day when I refresh this engine in say 10 years time, I will be looking for solid cam followers as I do have a couple of lazy hydraulic followers that clack away until warm. This will be better now there is fresh oil in her, but these overhead cam hydraulic followers are really an unnecessary item that give considerably trouble on ALL marques. My father has commented on this being a common Audi issue, etc. And yes I am aware they are cheap to buy but they will give trouble again ...
In the end the designers of these modern engines are over thinking and should have stuck to solid cam followers because with modern valve gear and materials the valve clearances simply don't alter and very, very rarely do they need to be adjusted. I had a Toyota Tarago that we checked all valve clearances at the 100,000 mile mark as per the service manual and every single one was perfect and they are twin overhead cam 4 valves per cylinder with solid followers. Plus how often do Nord engines need adjustment here ... again rarely and my Sud race engine also never needed adjustment even after a full race season with 9,000 rpm occasionally being used.
