LONDON, Sept 15 (Reuters) - Oil fell for a second day on Wednesday as pipeline operator Enbridge prepared to reopen the biggest Canada-U.S. crude line, which analysts said could limit the drainage of high inventories.
The yen slipped against the U.S. dollar and the euro as Japan's central bank intervened to sell its currency for the first time in six years. But analysts said immediate impact on oil prices would be limited. [
]By 1219 GMT, U.S. crude for October <CLc1> fell $1.15 to $75.65 a barrel, dropping more steeply than the 51 cent dip in the price of European marker Brent <LCOc1> to $78.65.
Canada's Enbridge <ENB.TO>, which has been hit by three pipeline outages since July, said on Tuesday it was near to completing repairs on its U.S.-bound 6A oil pipeline. Enbridge said it might also be able to restart the line without submitting to a lengthy approval process from U.S. regulators.
A report signalled the restart may come by the end of the week. [
] [ ]"The market driver today is the expectation that Enbrige (pipeline) will come back online sooner rather than later," Olivier Jakob, consultant with Petromatrix, said.
Discounts on U.S. crude to Brent crude steepened to about $2.75 a barrel after narrowing to less than $1.40 earlier this week. They were wider than $3.50 a week ago, before the line halted flows. <CL-LCO1=R> <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Graphic on Brent/U.S. crude spread:

The U.S. dollar extended its gains against the yen <JPY=> after an official at Japan's Ministry of Finance said intervention was not over. It climbed more than 3 percent on the day above 85 yen and above a 15-year low. [

"A weaker yen means stronger dollar, which should mean lower oil prices. However, the U.S. dollar and the Japanese yen have generally moved together as they are both considered as safe havens," Tony Nunan with Mitsubishi Corp in Tokyo said.
"So most people were looking at the U.S. dollar versus the euro, or a basket. Japanese oil demand growth is so bad and I am not too sure how much effect the yen will have."
Later in the day, oil market focus will shift to the U.S. official weekly oil data for the week to Sept. 10 from the Energy Information Administration at 1430 GMT.
Analysts in a Reuters poll forecast a 2.2 million barrel drop in U.S. crude oil inventories due mainly to the Enbridge shutdown. [
]But separate data from industry group American Petroleum Institute (API) showed late on Tuesday that inventories rose by 3.3 million barrels last week. [
