Head gasket OEM Toyota or OEM Subaru

The Tig won't need head gaskets at ~150k like every other subi does. The TSI pretty much has reliability nailed down now, IMHO. Change the oil and drive.

Mine went at 180k and took the engine with it due to loss of oil pressure.

My 2006 head gaskets were leaking prior to 130k. Ticking time bomb in my opinion.

Mine went at 160K so it’s coming soon. The single layered graphite that is on there now will always wear out quicker with time. It’s a “design flaw” and will always go out quickly.

Mine went at 220k, 2015 Prius V. Fixed it myself but I had the tools/time/interest. If you’ve overheated already it’s probably warped the head, cheaper to get a new (used) engine, have them put a new head gasket on that engine before it goes it to ward off future trouble.

the EJ25D, famous for blowing its head gasket and mixing oil and coolant inside the motor (in-laws had that happen, twice).
