Lot of blue smoke on first start

[sohelahmed]

aoa guys, my mehran 2006 model is used aas 4th or 5th car, mostly standing....

for last few months car is giving a lot of blue smoke on first start, its a lot and then after 15 mins its almost normal.....

car is 55k run and it has been 20w 50 being used in it...i dont know why..i think i should use 10w 40 or lower...

but now need your suggestion if it is due to oil grade or engine valve issue....

thanks,

Shot Valve seals

1st try to replace oil from 20W50 to 10W40 sometime blue smoke can also be observed due to use of wrong grading of oil and make sure you buy oil from some good shop as i have experienced. If it solves your issue then wellngood but if not then you might be have an issue of ring piston or valve

Engine seales are gone.

You have to replace the engine seals. An expense of around 10 thousand is waiting for you

Bro my cultus also gives blue smoke along with 1 liter oil consumption after 600 to 700 km what should i do?

[mohsan87]

Bad engine valvea and seals.

Depends from where you are getting it done from valve seals roughly costs 300-350rs/ seal you need 6 seals although valve seals can be changed without taking head off but no one will be willing to do it for you without talking head off

This much oil Consumption indicates pretty worn engine still you can try checking if pcv valve is bad it might reduce oil consumption

Your engine oil and Fuel are mixing.

I changed the pcv valve 6 month ago it costed me 900rs
Car pick is quite good but after 90 on 4th gear it starts missing gives jerks about 2 3 in 10 seconds
When i open the radiator cap its full of brownish type soft paste all around it and some on the top of the radiator it also floats on the reserver bottle of radiator!
This consumption is almost same on 10 40 shell also
Should i go for half overhaul (not willing to spend more than 20k) or assembly swap?

[sayedgulhassan]

Bad gasket?

[ch.daniyal3341]

Blown gasket, your oil and coolant are mixing causing that muck in the radiator. Your oil and fuel might also be mixing causinf blue smoke. Get thia fixed asap or you would need a new engine.

[saboor73]

Seems like gasket blown get it replaced also.chop of excessive metal from exhaust manifold that is usual.reason for below head gasket on carby cultus

[sayedgulhassan]

Im worried that this much oil consumption indicates fully worn out engine which will require complete overhaul which i am against...
