Excessive sludge buildup in cuore engine

[nfssaad]

i am facing excessive sludge build up in cuores engine.. around 90k km driven.. cng and petrol.. use zic hiflo oil from metro..

can any one tell me the location of pcv valve in cuore? also how to get rid of this sludge... dont want to dismantle the engine to clean it..

[margallar]

there is a pipe which connects the tappet cover to air filter box, that pipe should be branching somewhere and going towards the engine block, that will probably end at the pcv

[nfssaad]

hmm i see something there... but no bolts for disassembly... can some one confirm if that pcv valve can be taken out and cleaned or something...

[aamirq]

use an engine flush to get rid of engine sludge! and most engine oils sold at places like metro are fake!

[aamirq]

and most probably ur using the wrong viscosity recommended for the engine thats why sludge is being formed!

yes that should be it, it is removeable, look around it.

Metro selling fake engine oils??

[nfssaad]

always used 20w50...

i have seen similar sludge in other cng vehicles...

however i have a civic 96, more than 170k driven.. engine is golden inside.. no trace of sludge...

ab metro pay bhi fake oil hai to banda khud apni refinery hi khol lay

ps the civic is totally on petrol from the start

metro can't be selling fake oil

[talhawaleed]

Metro sells guard oil with ratings such as 20w-50 which is a very think oil for most gasoline vehicles especially with engine size varying from 600 c.c to 1300 c.c.

only good thing of guard is their air filters... baqi sab is junk
