I recently changed the oil in my 1998 Honda CRV and overfilled it. I don’t know exactly how much volume, but it was perhaps 1/4inch above the full line on the dipstick. To make matters worse, I then made a two-thousand mile round trip from southern California to New Mexico and back. I know, dumb.
Some things I’ve noticed, which I fear resulted from my mistake:
- I have an oil leak, I believe at the cylinder head cover gasket on one side, near the distributor cap.
- The oil level is now between the two dots on the dipstick.
- While driving down the freeway at 70mph, I thought I saw the temp rise a little and then drop back to mid, a couple of times.
What I really want to know is if I have caused any permanent/serious damage to the engine? I read some terrifying accounts online about people blowing head gaskets and mixing coolant and oil or getting engine oil into the transmission. Some people even reported bending crankshafts! Fouling spark plugs etc etc.
One last thing, the car runs smoothly, perhaps not as powerful as I would like, but gets approx. 25mpg - which is good for this model/year.
Any help/suggestions as to how I can determine exactly what has happened and what I should do next would be greatly appreciated.
