I'm going to tackle tearing my K46 apart tonight. I'm going to replace the oil with synthetic 5w50 and if I can find a place for it, I'm going to install a temperature sensor. (I picked up a cheap water temp gauge from Princess Auto that starts at 130F - I wish it went lower but it was cheap)
Anyways, here's my question: What kind of sealant should I use to re-assemble my transaxle with? I see people ordering the stuff in, but I have time to do it today and that's rare so I'd like to get it done. Can I use normal Hi-temp engine stuff used on oil pans etc?
