Spark plug clearance on a Chevy Optra 1.6? Hi guys,
Yesterday i had my spark plugs changed to bosch super. the preset air gap is 0.9mm and my manual says that i need 1.0~1.1mm. now my mechanic says that due to heat the preset air gap increases and it willl be 1.0mm once i start the car! is it true?
Also when he was changing the plugs we noticed that a little amount of engine oil was in number 3 chamber of the plug (not where the plugs ignite the inside combustion chamber, but where the cables go to reach the plug) he said that the TAPET COVER SEAL needs to be replaced and its not a big job and can be done later also. i would like to put it very precisely that very little amount of engine oil(around 1-2 ml) was found in it and he cleaned it and installed the plugs.
One more thing i would like to add is i have got my injectors cleaned at 17000kms(15 months back) and engine decabonised at 20000kms(12months back) now i'm at 30000kms do i have to get my throttle body cleaned and adjusted by removing it? i've also done engine flushing with changing the spark plugs.
by the way i'm having a chevy optra 1.6 .
please help me guys |
