Head gasket OEM Honda or OEM Subaru
Reviews
Use the MLS headgaskets... subaru part number 11044AA770. I never use the single layer gaskets when I do NA motors. Also stick with OEM parts. Especially when doing head gaskets.
Pros: OEM quality, reliable
Part number: 11044AA770
replace them with the head gasket from the EJ255 or 257. They’re made of MLS and most shops do that in order to make it last longer since they rarely blow.
Pros: last longer, rarely blow
Vehicle:
Subaru
642 head gaskets from a similar year wrx. Don’t use the same 633 or you will have the same problem again.
Pros: solves recurring problem
Vehicle:
Subaru
Part number: 642
If it's the typical 2.5 SOHC H4, that is the year and same mileage where my head gaskets failed on my Legacy of that generation. The failures are external leaks almost all the time so if you see drops of oil on your driveway, it's a good chance they are weeping.
Cons: external leaks, oil drops
Vehicle:
Subaru Legacy
My 2020 Accord 1.5t has 80K miles and already had to do valve cover gasket and now head gasket is blown. Then there’s also the issue of the front radar sensor that is constantly getting stolen because some genius at Honda decided to put this $700 part in the front of the car with nothing protecting it; looks like Honda just decided to give absolutely no f*cks when building this masterpiece. Oops almost forgot, had to replace the full head unit for the radio because it just decided to stop working at 50K miles.
Cons: head gasket blown, radar sensor stolen
Vehicle:
Honda Accord
Mileage: 80000 km
My 2015 Crosstrek blew a head gasket at 141k, only once ever let the oil change get past 5000 miles. Been disappointed with this car so far, needing a new engine, it'll probably be the end of my Subaru ownership.
Cons: head gasket failure, engine replacement
Vehicle:
Subaru
Mileage: 141000 km
Keep in mind I got rid of a 2013 Forester that had the infamous Subaru head gasket issue. Not an issue I want to ever deal with again.
Cons: infamous issue, unreliable
Vehicle:
Subaru Forester
I drove my 2003 Honda CRV with a blown head gasket for over 6 months. Drove it everywhere knowing it was on its last leg. The engine would go into “safe” mode often to protect the engine. That means i can’t accelerate past 60mph. Had to change the spark plugs once a month. Had to add oil and coolant every single time i drove it. Oil showed up in the radiator AND over filling the over flow. Finally gave out three weeks ago.
Cons: safe mode, frequent maintenance
Vehicle:
Honda
The Japanese car that's let me down has been Subaru. Two blown head gaskets resulted in the engine overheating and basically turning into scrap.
Cons: blown head gaskets, overheating
Vehicle:
Subaru
Unfortunately subaru only realized that the late 90s Subarus had an unreliable gasket material. They started switching to multi-layered metal gaskets around 99-ish. This is a really common issues with the NA 2.5.
Pros: multi-layered metal gaskets improved
Cons: unreliable gasket material
Vehicle:
Subaru
