Icon9 Crankshaft oil leak :(

So I'm not the most educated person with cars, but I do love my Lude and I want it to get fixed soon. I was hoping if anyone could give me instructions or tips on how I could fix my leak. It is leaking from the crankshaft(at least I think) the oil drips down the side of the oil pan to the ground. I'm leaking about 2 quarts a week and that's me only driving to school and back. Please help guys! Thanks in advance.

You have to take the timing belt cover off and look more. atleast the valve cover and see if there is oil on your timing belt. you may be lucky and have a bad balancer shaft seal or a leaky valve cover gasket dripping oil inside the timing belt cover.

Yeah, the guy whom I bought the car from was told by one mechanic that it could be the crankshaft and by another that it could be the balance shaft seal. I don't wanna pay $800 to get it done at a shop. I'll post pictures tomorrow and hopefully someone can determine where the leak is coming from.

Re: Crankshaft oil leak :(

Unfortunately this is one of those cases where your not gonna know EXACTLY where it's leaking from until you tear it down.
Take off the valve cover, and if you don't see alotta oil around the cam gears, that (unfortunately) means its coming from one of the seals on the oil pump; balancer seal, crank seal, etc. In order to change those seals, you need to remove the timing belt, and unless you know for a fact that the t-belt only has like 5K on it, you should almost always replace the timing and balancer belts, as well as the tensioners whenever you remove a timing belt. Also installing a timing belt isn't for a novice cuz you could ruin your entire motor if you do it wrong.

These oil seals are almost the hardest to change on the entire motor, tied with a rear main seal.

Re: Crankshaft oil leak :(

What you have circled is the connector for the Crank sensor and TDC sensor. it's hard to tell where it's coming from without the valve cover or timing belt cover off.

I'll remove both of them tomorrow, TGIF. School has been getting in the way of me getting this done. Sorry.

Re: Crankshaft oil leak :(

If it's leaking there from the top, there's a chance its a much easier job. Easiest would be a bad valve cover gasket, with the second easiest being front cam seals.

Turns out it's the cam seals. Mechanic is going to fix it next week for about $400

Re: Crankshaft oil leak :(

I'd have the timing belt and water pump replaces along with a manual tensioner retrofit while your changing out the cam seals.

Yeah, they're going to replace all of that at the mechanic.
