    Have some black smoke and 20% loss of power, but only after the 1.9dci espace warms up a good bit. When cold all seems fine. So have spent the past week checking all the fuel lines and taking live data for each injector and all various parameters like fuel temps etc. After about 10 trips I...

  3. General tuning
    Hi Has anyone tried a boost / bleed valve on a dci motor? I used one to great effect on a big turbo'd petrol engine, so I wondered if one would give a result on the 1.5 derv? Would the standard 2 port valve do the job or I've seen some 3 way ones and I'm not sure what they do differently...

    Hi All I posted a few weeks back about a busted aux belt killing my cam belt. Anyways long story short, cam pulley had sheared. I've stripped the head and got new valves etc as I didn't want to take the chance of a dinked valve. Can anyone tell me the suggested grinding/lapping time to seat the...

    Renault Energy 1.4 EJ6 Engine. Its low on compression on one cylinder, If I had the specs for cutting valves/seats I probably can fix this for next to nothing. I know the torque procedure for the head, everything else is accounted for except the cutting angle etc for the valves. I...

    I believe I am due to replace my accessory belts, pulleys and bolts at 5 or 6 years of age, despite the low mileage of 26,000. The mileage-based limit for this service is 72,000. If the valves clear the pistons on the 1.5 dCi diesel, and the belts pass a visual check, I am considering...

    ok so to cut a long story short i bought a megane with a failed head gasket. anyway ive now got as far as having the head skimmed, when i picked the head up earlier the guy said the valves had to be lapped in as the exhaust valves looked a bit naughty so I went and bought the valve spring...

Since then it has bent valves twice when all timing marks are perfect "timing has not moved at all" . It has bent the valves both...
