the performance changed quite a bit after changing the battery and oil, so much so i thought it worth mentioniing it here. the grunt from 80-130 kmph was unbelievable, i felt i put a 500's engine instead of the 300's. gonna go to the mechanic tomorrow to check on that issue of the smell of exhaust that comes at highway speeds. hopefully he fixes it cause i get awesome headaches after drving for an hour. wish me luk

edit: found out that the oil cap has a worn out seal, and engine oil is coming out from it. found a trail of dried up oil all the way down to the engine bottom from the cap. how dangerous is that? can the smell issue be related to it?

Placibo affect. Replace the oil fill cap.

just came back from the mechanic...found out that oil was leaking from 3 places:
1. oil cap(apparently the ones we get here have some defect , something about the rubber seal being too hard, and hence it cracks)
2. somepoint right between engine and radiator, seals were worn out.
3. somepoint at the bottom of the engine , another seal gone.

also the people who changed the oil filters let oil drip down on the engine while fitting a new filter, which would reach the red hot exhaust pipes at speed and cause the oil to burn , causing the smell at high speeds.

also the piston rings need some restoration oil to stop the small amount of smoke that come outta the exhaust when you really push the car. is it true you have to add the restoration oil while the engine is running?


so the mechanic is gonna change all the seals. also found out that my dad hadnt changed the tranny oil for 57000 kms (wtf!) so changing that as well.

thats all there is to update.

Its an M103, if its smoking at idle I'd suspect the valve stem seals.

thanks for the info.. will try to mention that to the mechanic without sounding like im getting info on whats wrong with my car from God

just a joke...i didnt mean anything by...hey what are you gonna do with that chair... ahhhhhhhhhhhhhhhhh!

by the way the car only smoke when you really hit the gas.. other wise its clean, so take it easy on the car and it doesnt smoke.

just to repeat the question, do you add engine restoration oil while the enigne is running? you know the stuff that helps keep ur piston rings in shape and do their job of stopping oil of burning with the fule and air?

No oil can replace worn metal. Again snake oil. However valve stem seals can be helped with additives. Anything that is ment to swell seals, for example high mileage oils. I had an old Toyota with bad valve stem seals and after 20k miles on one of those oils the seals had softened up to the point that it didn't smoke anymore.
