I'm back for the best advice I ever get. I love this website, it's helped me keep my van going and going. Right Turismolover22? Ok, question. I have a very small oil leak, either from the crankshaft or camshaft, can't tell exactly because of oil mess on undercarriage. But if I take off timing belt cover, I can see small leakage on side of engine. I've had a few people tell me to put some Lucas stop leak in motor. I'm really reluctant to do so. Because most of what I know about cars I learned from my Dad, who was old time truck mechanic. But was a great mechanic and he always told me never use additives to stop leaks. What's your opinion? How bad does it leak? Mainly when I'm working, which pretty much keeps car going for about 7 or 8 hours. So, if it's hot out and about 70 miles in 7-8 hrs. City driving back and forth. 1/4? of a quart, just depending how hot it is outside. Winter not so bad.
