This is great! Subaru wanted $144 to replace my oil sending unit. Just picked one up for $12 and will do it myself. This video was a great help.

+Billy Eickholt Great! glad I could help. $12 is way better than $144!

Thanks for the help! seems we had the same leak from the oil pressure sender and I had no clue where to find it.

This is a common and mercifully cheap oil leak point on the old Subarus. Glad I could help.

Interesting on my 95 Impreza 2.2 I have an oil leak and when I look at my intake manifold its covered in oil and it drips down to the exhaust and smokes at times. Wonder if my oil pressure sending unit is causing it to leak oil

I'm not sure if the oil getting on your intake manifold and exhaust would be from the sending unit but it's so simple to check that you might as well check it. The leak you describe sounds more like valve cover gasket or head gasket leak to me. Maybe try cleaning the area well with some carb cleaner type stuff and seeing where 'new' oil comes from. good luck with it!

I changed mine today..The stock one was 24mm, the new 27mm..I didn't have one but 1 and1/16 socket worked.

2007 Subaru Impreza Knocking/rattle sound

Help! My 2007 Subaru Impreza has had this annoying knocking noise for about a year. Recently it broke down on me and i couldn't get it started back up.

@beqa16v The EJ engines suck if they are not looked after with quality fully synthetic oil, if the owner doesn't look after their engine by having it serviced regularly then problems like this are bound to occur. I get my MY00 WRX serviced every 10,000km and I change the engine oil half way between each service, so every 5,000km the engine oil is getting changed. My WRX has done 170,000km and has no issues whatsoever and has a tuned ECU along with 3" TBE and an upgraded fuel pump.

That is a very expensive noise. Sounds like you've spun a shell very common with EJ25 and EJ20 engines Had it on my P1 total engine rebuild cost £5,000 for 450BHP. If you stay standard you may get it down to about £2,500 Not sure where your from but API Subaru in Warrickshire do a bloody good engine Good luck.

So its kind of funny to say that I worked for LQK / yamato PW for about a year and we remanufactured Subaru engines for that specific problem.. its called death defying piston slap from a lopsided cylinder.. that engine is well known for it.. I could definitely be wrong but it definitely sounds like so.

Alright mate we had the same noise with my Subaru I found behind the flywheel is a oil glary but the 6 screws one fell out picking it up making a really bad noise but on idle (tick over) sounds perfect but 1400rpm is when it really rattles hope it helped

these boxer engines absolutely suck! so overly complicated for 4 cylinders and without any real advantages. Plus the turbocharged ones can take so few miles that it is disgusting
