HI
i have 2001 Celica gt. 200k. changed clutch and transmission recently.
1. celice is burning engine oil (~2 litre in a month). back bumper of the car get black near muffler. oil burn happens mostly when driven on higway speed. when i check the oil gauge, the oil color is black. on street speed everything is perfect. even on highway there is no lack in power or speed. great pickup and can reach 190 km/h. can it be related to timing belt? becuase some mechanic had a look at engine and suggested to change timing belt.
2. other problem is that when on highway speeds. engine jerks sometimes. lets say 3 or 4 times in 200 kms. and sometimes no jerk at all for 120 kms. it seems like engine missed the blast and skips but then runs smoothly again. i have changed spark plugs, oil filter and tried flue injector cleaners.
can it a problem relted to oil/air mixture?
any help will be greatly appreciated
Thanks!
I love my Celica
