Oil filter cap missing internal stem
2015 Lexus is250
How much damage could have been done from driving the car withthe oil filter cap missing the internal stem? I bought the car in June with 78k miles and changed the oil last week at 83k and noticed the oil filter cap didn’t have the stem. I haven’t driven the car since then since I’ve been out of town and while I was I bored and watched a video of the oil change and noticed mine was missing the stem, when I changed the oil I didn’t think much about it since the only other car I had didn’t have that stem. When I changed the filter last week the old one was not collapsed in on itself and looked fine and I haven’t noticed the engine knocking or anything abnormal in the time I drove it up until I changed it. Will me driving it up until I changed the oil and however long the person before drove it without this have caused any issues to the engine? I already bought a genuine oil cap with the stem and it should get here tomorrow so I’m hoping too much damage hasn’t been done.
