    Unhappy problem in mehran engine -- please help

    salam, i am having mehran 2001 model car. i was burning oil and generating blue smoke in morning, its valve seals and rings are changed in Feb 2010, after changing these items, i used the car carefully like changing gears properly, checking water level so that it does not overheat (infact using coolant) , does not overspeeding etc. BUT what i did wrong is that i used same engine oil which was put after replacing rings.
    Some days ago , i used to touch 80Km/h and 90Km/h speed but one day i reached at 100Km/h speed , engine oil was used about 2200Kms, from next day car again giving blue smokes. i told the mechanic , he told me to change engine oil, i did but smoke remains there for 2-3 days
    Now there is very minor blue smoke and its also not on regular basis (some day it appears and sometimes it does not), one mechanic is telling me that this will vanish in next oil change.
    i don't know whether valve seals or rings are blown again ?? what might be the issue as i checked the oil level after 1000Kms, its almost same
    My car's gear oil is leaking , is this smoke due to this ?

    Tunning karwao and next time you change you engine oil make sure that the oil chamber nut is opened for atleast 15 mins and also shake the car.

    bro if gear opil is leaking then ur some seal must be dameged or it might be leaking in other words.u can get it replaced and it'l be ok.

    2ndly after getting the motor build no1 ever uses burned oil again but dn know y u thought of using it over again.khair anyway.get oil change cz the oil ur using has already been burned,if u keep on using the same oil then u might face problems again,but to avoid that its better to change the oil and if ur using gas then just dont go for the gas one,go for simple/normal havoline plus use the car onpetrol a bit.v all know its pretty much expensive but still u have to keep ur new built motor in the best condition so,go for an oil change and use the car on petrol for some kiolmeters with cr beng tunned on the petrol if ur already running on petrol then its fine.and after this oil change try to maintain oil change at 2500-2600kms for optimum performance!

    Thanks for replies.

    yes, its my fault that i used the first oil for 2200Km after engine rings are changed.
    Now i changed engined oil and mechanic is suggesting that this oil should be changed early, its 1000Kms driven should i change it now ? or valve seals need to be changed as there are minor oil like patches / crystals in radiator

    just go for the oil change,it should be ur first priority,blue smoke would go away in 2 il changes approx.just change this oil first and then change again at 2000km after that u prob would be gone and u could take the milage to 2500-2700km,
    i dont think u need new valve seats cz as u mention that its happening off and on,so check with oil first InshAllah hope that ur prb would be cure!

    Sorry to say this buddy but you're going to keep wasting your money on new oil now which is primarily due to wishful thinking. Blue smoke= due to oil burning. Blue smoke at startup=valve seals being shot. Blue smoke under normal driving conditions=rings being shot. What brand of rings did you have installed on your Mehran? Unless you used the shittiest oil out in the market, get a compression test done to confirm.

    Btw... gear oil leaking on Mehran is a very common and chronic problem, also this is NOT the cause of your smoke issue.
