Hey guys, um I brought this xr6 over a week ago and the day after I gor it I noticed the engine had a slight knock, obviously I checked the oil first and yeap, empty, So I put about 3L in it to bring it to ok on the stick, (I've checked the dipstick about 10 times since then, hot, cold when ever, and it's not dropping anymore.) I think the guy thrashed it big time but I'm looking after it, also it's an auto! Just wanting to know if there's any comon oil seal or somthing? Thanks guys!
