Let’s Disassemble this Subaru Boxer Engine with Basic Hand Tools! | Subaru head gasket repair

Today we are continuing the work on our 2010 Subaru Impreza. As expected, this Subaru has leaking head gaskets. In the previous video we removed the engine from the vehicle using basic hand tools. Now it's time to tear down the engine and remove the cylinder heads from the engine block. Cheers.

Well organized and well presented as always. The boxer design may excel at promoting a low center of gravity, helpful in racing or rallying (far less useful in a street car), but it is a complete PITA when working on the engine, including something as simple as changing spark plugs nevermind headgasket replacement which, in an inline 4 is a relatively straightforward engine- in-car task. Then again, since coolant and oil drain down in an inline 4 design rather than having to be continuously separated by the head gasket in a boxer design, head gasket replacement is less likely or would be necessary after greater mileage. Anyway, the video is a credit to your ability and resilience!

Man thanks ! I've been looking almost everyday on you channel if that video had come out since you published how to remove the engine.

[@niefrank5510]

Perfet. I just have one question about the cylinder head bolts. Did you change all of them?

[@espnocho7904]

Great video love your channel is the bottom single bearing idler on the timing supposed to rust like that. I have the same thing going on and I changed my timing components late 2018 with a Aisin kit. Wondering if it’s a cause for concern.

[@CarsNToys]

Good question. No, it shouldn't rust. In my case the timing cover had a small hole and condensation was entering the area.

[@JonathanVaucher]

I wonder if the weathering on the timing bell bearing is because it's an aftermarket non-OEM TB kit. When I did my TB change at subaru, they wanted to install an aftermarket kit. I figured it out when checking the part numbers on the bill estimate. I told subaru NO NO. I only want OEM Genuine subaru parts. They ordered all the OEM part then and installed them. I don't mind paying 300$ more for quality parts if it means I won't have a busted engine. Gates TB kit have been cheeping out, with many of their japan part now being cheaper chinese parts. Bearing that rust so easily is certainly not a good sign. They also cheaped out on the TB tensionner. As for the waterpump, the OEM subaru one lasts forever, whereas the aftermarket ones have a reputation of going tits up quite fast.

How screwed am I? I moved the cam sprocket while trying to take it off. Where do I go from here?

[@steveo782812]

If you had to remove that cam gear without the impact could you put rope in a cylinder so that a valve pushes against it? Is it really doable without the impact. I agree impact makes it so much easier. Secondly you mention keeping track of the fasteners for the cylinder head, but are you going to use new fasteners?

[@CarsNToys]

Thank you. Yes, I reused the fasteners.
