Mallory Posted February 6, 2019 Share Posted February 6, 2019 Can I replace the head gaskets on my '03 Forester without pulling the engine out of the car? Is there room enough inside the inner fenders to get the heads off? It's looking like that is the source of my oil and anti-freeze leak.

idosubaru Posted February 6, 2019 Share Posted February 6, 2019 confirm the leaks. yes it can be done but it's not ideal and need to be very careful to get a proper job that way. Quote Link to comment Share on other sites More sharing options...
3Pin Posted February 7, 2019 Share Posted February 7, 2019 Dang, it is a bitch to leave it in. If you have to do the HG, it is so much easier to wrench on with it out of the car. I would do the timing belt, water pump, all idlers, cam o rings etc while it is out as well. Send us pictures of your knuckles if you leave it in please. Just kidding.

GeneralDisorder Posted February 7, 2019 Share Posted February 7, 2019 We don't do them in-car. It's too difficult to ensure proper surface prep and bolt torque. The biggest issue is not being able to adequately clean out and lubricate the block threads. Just makes it a pain in the a$$. GD 1 Quote Link to comment Share on other sites More sharing options...
Mallory Posted February 7, 2019 Author Share Posted February 7, 2019 OK, you convinced me! If it turns out I need new head gaskets I'll pull the engine. Thanks for the advice! Quote Link to comment Share on other sites More sharing options...
