    I blew my head gasket at 186K. I did some bad things such as using sealant so that sealed a lot of things.

    Fast forward, I replaced with Jap Engine and have about 204K now . Once I went long distance for 100 miles and at about 100 mph, seems the car could go faster. For few months since if I push the gas hard for long, I'd get the engine heating icon on the dashboard. It would disappear intermittently.

    Its been a good year , since I have been using the car and the engine heating icon never appears , I make sure I dont push it too hard for way to long like 80 mph for 50 miles straight and its been running great. Should I stil get the EGR valves cleaned or should I worry about it coming back.

    Were the intake manifold (has EGR passages) and EGR components cleaned in the course of the engine replacement? If not, they’ll be more-or-less completely carbon-blocked by now, should definitely be cleaned, and recleaned at least every 50k miles.

    My 2 cents: neglected EGR cleaning is why you’re on a second engine.
