oil would just let the belt slide off. it won't snap.
how long...eh nobody can give you a definite answer cause well its impossible to predict.

even if your belt comes off your motor won't blow up....non interference motor.

just have someone fix ur seal

oil will expand the rubber and cause it to jump timing most likely, but COULD weaken the belt and cause it to snap. have you ever seen a serpentine belt from an oil soaked engine after a year or 2? its not pretty. i know a serp belt is not the same composition as a timing belt so its not a direct comparison, but rubber and oil is generally bad.

yep...like i said earlier, oil will cause the belt to snap earlier than its normal life. I say that cause it happened to me twice under 7k with new belts.

I had a pretty bad crank seal leak on a prior ride that leaked oil within my timing belt cover and soaked up the belt pretty good. Problem was I couldn't figure out where the leak was cause oil was everywhere and when I cleaned the area, the oil wouldn't leak out unless I was driving the car so it was hard to pinpoint.

was wondering more about the dmaaged crank or scrtach that the belt breaking..

the damage crank should be "taken out" and turned and then if it's out you should go ahead and get it balanced and polished...that's a great upgrade for the crank. At least get it turned...it's the best way to fix your problem, gaurantee long life, and stop the future headaches that are sure to come with a quick fix.

Hold on here.

From my understanding the scratch is where the front main seal goes. If it's not, and is where a bearing sits, disregard.

Turning the crank means you machine down the area where the bearings reside, NOT the area where the main seals sit.
So turning it would do nothing for you problem, and just waste your money.

I would suggest
1-see if it's leaking from there. Yes you have to tear the belt back off, but you have to anyways, unless you're going to ignore it.
2-if it is [or even if it's not] I would try to polish it out with crocus cloth, depending on how badly it's damaged.
3-If it's not damaged badly, potentially you might be alright with just that. It might need to be filled as well, as bitter described.
You also have a little bit of leeway as to exactly where the seal is positioned on the crank. You can push it in or out a slight bit. This MIGHT be enough to clear the scratch.

If none of the above works, the crank is junk.

A long time,

I think you need a new mechanic, I suspect he was getting ready to rip you off big time, there is nothing he could see to indicate a scratch in a critical area without removing the oil pan and rod/main caps, Only area he could possibly see just changing the timing belt is the front seal area on the crankshaft IF he popped out the seal and looked, either way, if it's damaged or worn, you should be able to get a stainless steel repair sleeve like these:

thin sleeves that you coat the inside with loctite and drive on over the damaged areas, gives the seal a new smooth place to ride search for balancer repair sleeve or crankshaft repair sleeves

he did remove the oil pan before telling me what was wrong and did smooth out the crank i have put about 400 mies on the car since and no overheating or problems so am i out of the woods?
