Over past year the FJ40 has developed a pretty good header/intake leak. I was 1st tipped off by the typical header exhaust tick. I re torqued the studs/bolts and that only helped for a couple of months. This time the leak got worse. I could smell exhaust real bad while driving down the road with the windows rolled up. I did some reading and Remflex REMFLEX Exhaust Gaskets: Home Page came highly recommended. So I ordered one. BY the time it arrived I had already removed all of the old and fried gasket material from the intake, header, and head. Installation is very easy, however you need to make sure you do not break the gasket as it is kind of brittle. After everything was buttoned up, I fired the 2F and WOW what a difference. No more exhaust noise or smell. Best of all no leaks for the intake and I had a noticeably smoothing running engine.
These gaskets are awesome and I highly recommend them. However, they are pricey.
Only the best for my 40.
