2005 outback losing power

10

Asked by Jun 18, 2017 at 03:35 PM about the 2005 Subaru Outback 2.5 XT Wagon

Question type: Maintenance & Repair

The vehicle began to lose power under load and up hills. Idle stayed smooth for a week or two. Also produces a loud metalic ratcheting sound at around 4700 RPM. Is not fuel filter, MAS. Mechanics have had it for two full days and don't have a clue.

Have them inspect the timing belt if they have not already.

XT - is the turbo working properly?

You'll have to find wrenches familiar with the turbo iteration. Loss of power at speed often points to an old MAF sensor, but your high rpm chatter suggests rod knock from prior abuse. Too tough without eyes on it....

The problem was the timing. A timing cog on the cam was failing. The sound was the timing belt tensioner trying to restore the timing to the proper settings. Pricey fix, but glad to know what is was. Thanks to all for your advice and suggestions.

So it was timing belt related. Glad you found the problem.

Subie's tensioners use a small internal hydraulic shock that keep the t-belt at tension. Occasionally the shock's oil seal will leak, bleeding out the oil and resulting in flop. What you're hearing is the loose t- belt whacking its outer case...NEVER a good situation. Good that you didn't bend a valve!

Guru9VBMQ-. How many miles are on this car? And, when and at what mileage did you last change your timing belt out?

Hop away, Grasshopper...you're off-base on this one again....
