i didn't think i run out ideas i like to add, install, or upgrades to make on my 2014 base trim. yes there's plenty more things or customization out there but the truth is that my ct was never intended to a dream show car that i baby it. But it has so far exceeded my expectations. it was all bout how much $$ cost to own/operate, reliability , practical use daily car. The Lexus quality & design in the ct Hybrid made it my dream car on a budget. (fancy prius) lol And now that it almost 85k. got some major maintenance work up ahead that needs service to keep it running til idk forever? i think the EGR system cleaning will be my biggest work. spring/summer 2021. i looking at parts diagram and layout and noticed each connections has gaskets. already ordered the intake manifold & throttle body gaskets, need one from pipe to egr cooler both sides, one for pipe to manifold. more? the tutorials videos on youtube didn't replace or mention much about replacing or reusing gaskets. i was able find some of them but some maybe lexus dealer? my question seem like no brainer, should all gaskets be replaced? i ordered one of them on ebay from lexus parts dealer, gasket was metal. i'm still trying locate remaining ones. probably need dealership parts.

 

All 3 gaskets are metal. They've held up well the last 3 or 4 times I've had the EGR apart and clean up well with a little brake cleaner and rag

 

Since they're so cheap, it's cheap insurance (at least time wise) to use new gaskets whenever performing a big job. So yeah a no brainer
