Yes, me again with a soliloquy about my troublesome 175 Turismo's thirst for oil. Following tobydmv's advice I've stripped down the upper engine and discovered a surprising amount of wear in the cylinder bore - a very pronounced ridge is visible mostly on the rear of the bore which, I imagine, cause...

Thanks tobydmv for your opinion and advice on both my recent(ish) appeals for help. I 'll follow your suggestion on checking ex. valve guide wear. I discovered that the oil filter cover screws are M6 thread and these types of fasteners are commonly used in automotive application for holding the brak...

My (indelible ?) marking system has failed on the pushrods : I assume I'm correct in thinking that the exhaust pushrod i...

I have in the past been a member of it and found it helpful but my interest in Morinis today is only for the old single cylinder models and a few years back everyone in the Club seemed...

Hi everyone I've just joined the group and am looking for some help & advice ! I'm just starting work on restoring to running order a 175 Turismo that I bought in northern Italy a couple of years ago. According to the insurance document it wears it's not been in road use since 1972 so I might be...
