Default Throttle Body Won't Come Off

Bought a TBI rebuild kit on Rock Auto since the TBI is leaking between the gaskets. Can't get it off since it's stuck. Anyone know any tricks to get it off without damaging it. Tried a rubber mallet and the mofo won't come out. Don't want to wack it and end up destroying something!

I've never come across this problem before and I've taken off my TBI many times including one time to rebuild mine.

Maybe warm the engine up and then put a 2x4 piece of wood and tap the TBI and see if it comes loose.

Verify that a bolt is not hiding.


Then start taping on it...as mentioned.

TBI Allen head bolts are 6mm. A socket head Allen tool with an extension and ratchet is the best way to remove the bolts. Remove the 4 bolts and tap it loose(hopefully!).

I removed the 4 bolts that keep the TBI in place. That's the only thing holding it down. I'm verifying with the FSM and even watched a YouTube video to make sure I'm not missing anything.

Managed to get it off. Had to pry on one side with a screwdriver and lightly tap. After a few taps it came off. Damn gaskets are crusty!

Glad you got it off!

Just be careful not to drop any of the gasket material into the intake tunnels. Maybe tape off the opening for prevention and also be careful if you're scraping off the material as not to gouge the surface(s) and create uneven spots. Otherwise, vacuum leaks will occur.

I use Loc Tite Chisel to dissolve the gasket material on my Sea Doo's when I rebuild the motors. No gouging. No air leaks.
