Oil leak at the outer side of the cylinder-head

Hello Everybody! Because of a false valve-stem seal I had to disassemble the front cylinder-head, and send it to a service-men to replace the head. After re-installing the head, I went to the petrol-station and realized that the left side of the engine is covered with full of oil. I thought it was t...

Re: Poorly Veloce

Does the Morini Veloce cylinderhead get enough oil?

Presumably the wear on the camschaft, the fast worn valve-guides and the noisy head is caused by short oil. I think, if there is not enough oil, driving the camshaft require more power, and the result: broken camchain.....

Am I right?

Re: Veloce head work

Hello! For reliability issues do not forget to change the valve-guides to bronze. Renault 1.5 dci engine has almost the same guides made of bronze.

Re: Disasembly of Cylinder-head & replacing Valves and guide

Hi! After disassemly I measured 0.5-0.8 mm side dislocation of all valves. Some hours ago I got one of the cylinderheads with replaced valve-guides. Renaul 1.5 Dci engine has the same sized guide made from Bronze, only the end should have been machined by lathe, it was needed some mm to cut down. No...

Re: Disasembly of Cylinder-head & replacing Valves and guide

I have a small problem. Now I disassembled only the first cylinder. The back is untouched. I marked the cam-chain and the amid laying timing-gears with blue paint. I moved the engine to the OT by moving the back wheel with switched 6nd gear. After that I realized from he manual, that there is a smal...

Does anybody have any idea, which more widespread car or motorbike has the same or similar exhaust and inlet valves and valve-guide than the morini's?

Re: Disasembly of Cylinder-head & replacing Valves and guide

Thank you for the advice. Hitherto every stage of disassembly was easy. I am sure that the Assembly will be much heavier :shock:

Disasembly of Cylinder-head & replacing Valves and guides

Hello! Because of abnormal noise (rattling) coming from both cylinder-head - which is louder when the engine is warm -, I decided to take apart the cylinder-heads and - when too worn - change the valves and valve-guides as well. The exhaust valves are white coloured, and the inlet valves are a bit c...
