What's going on?

So, A couple months back my niece and her new husband from Korea (She was over there working for a few years) decided he needed a car but being of modest means and thinking I knew something about cars asked me to find him something. I showed him a few cars and when I mentioned there was this Subaru Outback that looked pretty good but was hit in the back, he said, hey, I really like Subaru's! So, I thought of all you guys and figured I should get this car for him and fix it up. It wasn't a project car like my XT6 but I got to know it a bit and have to say it was really assembled nicely. The parts I had to mess with were all well designed and fit nicely. I finished it up last month. Here are a few pictures of the finished product I took in my garage before I delivered it to him. I have to say however the engine's valves or lifters are crazy noisy. I read online that it's a common problem but whoa! I flushed the engine and changed the oil twice in an act of desperation for fear he'd think I found him something that's going to blow. The tapping really didn't improve very much. Anyway, it's a nice car. 2004 with only 104000 KM (61000 miles) and was well maintained.

Nice looking Outback. May want to check the valve lash adjustment.

Thanks John but best I can figure is that sounds like a lot of work for a car thst's not mine and I'm tired of working on. But I'll pass it on to my niece's new fella. Cheers

All rear EA82 and ER27 (XT6) disc pads are exactly the same. There is no variation or other option available.

All EA82 and ER27 rear struts are interchangeable although they differ in overall height (different mounting locations for FWD and 4WD, spring/dampening, and adjustable/nonadjustable.

If it lessens as the car warms up then it's just piston slap which is benign. Ignore it. Nothing you can do accept disassemble theblock and knurl the pistons of install updated pistons.

Timing tensioner should be checked. They can loose hydraulic tension and slap and sounds awfully similar to rod knock.
By age it's 7 years past due for a timing belt job.

Many thanks Gary always. I've come to appreciate that guys like me do things but don't know why we're doing them whereas others like you understand how things work and as a consequence, know what ought to be done and more importantly, why. I'll pass your observations on to my niece's significant other.

Well I don't know anything about other manufacturers, just Subarus. I've worked on tons of 95-05 Subarus over the years and studied and researched them to death.

Pardon the previous brake comment, working from my phone I saw a new post but it had opened to the first page and and I replied to hat. Duh.

As for the tapping...The 2.5 has manually adjusted valve clearance, I had to do it on my wife's Impreza....wasn't too bad, just have to pull the valve covers for access.
I had put it off forever, but once I did it, it really wasn't too bad, and the car sounded SSOOOOO much better.... :)

Thanks for that Huck. I'll pass that on to him as well. For whay it's worth, he picked it up Sunday from the in laws house where it's been sitting since I finished my work on it and drove it home to Waterloo (3 hr drive). He said the car drove great and the tapping noise was almost not noticeable. So it clearly diminishes as it warms and drives. Again, thanks to all for the kind tips and advise.

Yep sounds like classic piston slap.

Those valves get tighter over time so it's also wise to check them at least once around 10 years or so anyway so you don't end up with burnt valves (usually exhaust).

Since the valve covers often leak I just usually plan a valve cover reseal and check clearance at the same time party.

Greetings to everyone. Hope you're all well. I haven't gotten around to restoring my 87 turbo yet but I did take out my H6 after a year-and-a-half in storage. It drove well for a month or so then noticed a few things. 1. "Power" light in instrument cluster flickered often and more so when car was idling or stopped. Although it did also from time to time when driving at speed limit as well. 2. Car stalled a few times which was completely out of character. 3. Felt like transmission was slipping as it would jump in first gear and jerk occasionally in other gears periodically but more often so in first. 4. Noticable whinny/humming sound coming from rear trunk area while running and continues for about 3 minutes or so after car is shut off. Tested battery and alternator. Told battery fine but needed to replace alternator so I did that with a Bosch rebuild. I also removed and replaced the transmission filter and of course put in fresh fluid. As a consequence of those steps, the gear jump/slip is much improved but occassionally temperamental and the same holds true for the "Power" flashing light in the instrument cluster. It shows much less and more fleeting when slowing to idle or at idle. The whiny humming sound has me stumped. I can hear it when driving and as I say it continues when the car is shut off. I've put my head in the trunk and climbed underneath to listen after the car has been shut down. It's not the fuel pump, which I replaced when I replaced the fuel tank during the restoration. It sounds like it's coming from the tank itself. The only thing I know that's in there is the fuel guage sending unit and I doubt that would make the noise. I'm wondering if it could be a vapour purge solenoid but then again, I hear it in the back, so.. The car passed an emission test two months ago which I needed when I took it out. I don't have a check engine light, but then again it stalled a few times, but not since I replaced the alternator. As always, would appreciate the benefit of your learned advice?
