QUOTE(dwRK @ Jul 11 2024, 01:02 PM) engine top cover leak is normal after few years... and is not related to overfill... no, bro. if we are talking about >20 year old engines you might be ok to overfill the EO.overfill by 1-2cm is not a problem and doesnt cause damage... max line just tells ppl got enough oil liao, its not a "danger do not fill over this line or your engine will explode"... chill la bro don't sweat it...  modern engines are designed to tight tolerances and overfilling can cause pressure build-up and damage the seals and gaskets. there is no easy way to know how much EO is too much so the best policy is to just follow the indicators. |

If overfill 4mm-5mm, still ok?if your car has a long dip stick... you have a wet sump... if you badly over fill and cause crank counter weight to "churn" the eo, you will lose power and vibrate more at high speed... of course excessive over fill is problematic, a bit over the dip stick dot is ok... engine designs have built in tolerance for such things... |
