    I think Mick Papworth was still doing this until fairly recently

    This was done on my rebuild, by Mike about 8 years ago, though I read the engineer who actually bored and sleeved the laygear was not doing it anymore. I assume Mike can longer offer this service?, What a shame these old school skills dying out!.

    Plugs are dry so no fuel getting through

    I had a starting problem on Vitesse. Even after lot's of cranking with choke, the plugs were dry. Assumed it was a lack of fuel issue. Turned out, it was dirty/oil fouled points contacts.

    I still don't understand, why the plugs were completely dry?

  7. Real world acceptability of crankshaft end float

    in Engine

    Posted · Edited by daverclasper

    Hi. This is related to my Vitesse. I know the WS manual tolerances for end float, that would have been for cars, maybe clocking high mileage in the day.

    I'm aware this is a "how long is a piece of string?", type of question, though as my car does low/gently driven mileage, can I assume that a few thou, higher than factory spec, is probably ok?.

    Cheers, Dave

  10. Vitesse 2 Litre Mk1, oil leak from rocker cover area I assume, but where?

    in Engine

    Posted

    Hi. Not a big issue, as such, I assume? (though leaks in this area, can also affect fuel mixture?).

    So, no obvious traces of oil from rocker cover filler cap, 3 top fasteners, PCV stub to valve hose. I cant see any fractures/oil deposits on actual cover.

    Even though I wipe it clean often, there is always oil that collects within the rearmost area (as engine slopes down at the rear) of the recessed lip, which part of the gasket pressing  section of cover.

    I can't think how it gets there? .

    Ta, Dave 

     

     

     

     

  12. Hello from Paula and her Vitesse

    in I thought I'd introduce myself

    Hi Pete. I know this is the 1600, so maybe different volumes, than the 2 Litre?. By coincidence, I recently asked about the oil volume between upper and lower marks on the dipstick for the 2 Litre and the reply was that is was about a 3rd of a litre, which seems a big difference?.

    Related to part of this post below

    Thanks

    next time you do an oil change check whats on the dip stick 

    add 3.5 ltrs should give you the low oil level mark, add the last 1 ltr  should give you the full mark 

     

  16. Checking valve guide wear

    in Engine

    Posted · Edited by daverclasper

    Thanks guys.

    John, I did a comp test about 3 years ago (before I noticed the oily plug issue developing) just for general interest. Looking at the figures I wrote down, no2 was at the higher end of figures that were within 10% of each other. An average of 190 (though I guess the gauge reading high).

    Of course some engine wear/damage could have occurred since then.

    I will do another comp test, when have a some time.

    Could it be possible that just the oil ring on no 2 has failed/or carbon stuck, therefore burning oil, though compression rings/bore ok?

    It has always used some oil (since 25,000 miles ago when I bought car) and has sometimes/often, smoked a bit at idle and when revved up a bit.   Never appears to smoke noticeably, when started from cold, even after a couple of weeks..

    No big deal for me, I don't think. Just interested and enjoy learning.

  17. Checking valve guide wear

    in Engine

    Hi. I have had on Vitesse, no2 cylinder spark plug oiling, up for a while now, after slow city driving (burns off on faster runs).

    Without removing the head and dismantling the collets etc to free the valve, Is it possible to get some idea of possible excessive wear, by rocking a valve side to side, or will the spring tension not allow this?.

    I will probably live with this anyway, as still runs fine (burns a bit of oil), though interested if it can be checked to some extent, next time rocker cover is off

    Thanks, Dave 

  19. Strom 150cd carb balancing with straws

    in Fuel System

    Posted · Edited by daverclasper

    Hi. Pete once mentioned this technique as very accurate I seem to remember?.  It involved (I think ?), removing the damping pistons and replacing with a straw in each tube. When the straws are at the same height with engine running, then the height of the jet needle pistons are also equal and therefore the airflow into each carb is accurately synchronised.

    Can anyone confirm I have remembered this correctly?, please, as would like to give it a go sometime.

    Thanks, Dave

    There's a guy on E bay "Spitfirespares", I think, besed in Tavistock, seems to have a lot of used parts, at reasonable prices.

    Which are the places you've tried so far?

  21. GT6 Mk3 only runs well with VERY advanced timing. Any ideas why?

    Theres two issues here Dave. One, lower octanes than our cars were designed for which as you say can be counteracted by retarding ignition. Then two, the increasing percentage of ethanol being added which is much more of an unknown.

    For the latter we're postulating that advancing the ignition might produce more efficient combustion because the ethanol burn is slower and so possibly not completing until too late...

    Thanks for simplifying/summarising the thread Johny.

    As a layman with a standard car, in general use, I guess, I'll just keep with the "Retard, until it stops pinking" ,technique.
