    Default Tick from motor at certain rpm

    Hey all,
    After an embarassing story, my oil filter ended up dropping all my oil, i stopped shortly after but the engine has generated a slight tick at only 1 certain rpm, at 1600rpm, this happens off load too. I wouldn't say its a rattle, but could a cam journal be damaged as a result?

    I only had spare oil at the moment so i am using 5-30 but the engine wasnt making this noise prior to dropping oil.

    Is there any chance lifters could be making this noise? It doesn't happen if i try take off from even lower rpm and goes away shortly after.

    I am doubting big end as wouldn't the motor usually rattle at all rpm? Not so much in one specific rpm.

    Could the choice of temporary oil be a possible cause? This has been the only oil i have been able to try so far.

    i vote big end..

    similar thing happened to me when i was younger with a 4age... oil light came on only to realise that after about 4 weeks of 'spirited' driving (it was my first 4age, and i was 19...) it seemed to use almost a full sump of oil... i limped to a servo to buy some oil.. topped up.. went home..

    the coming days saw a slight tick tick on idle... which would go away once any form of load would come on...

    the cure for this... was a 4agze half cut... and a few brushes of limiter love and the ticking noise lead to dead big end being ejected through the block and sump..
