Thread: VE throttle body screws coming loose.

It seems there are more and more instances lately of this happening and it seems to be all ve throttle bodies whether the stock one or n1 throttle body. Does anyone know whether this was a recall in japan for the ve motors.

Might be good to put a sticky up in this forum to let everyone with ve's know to remove the screws, apply red loctite and reinstall to avoid this happening more often.

I dont know why nissan screwed up around those years by not loctiting the screws, same issue on the Spec V's the first 2-3 years they were produced with the butterfly screws coming lose and being injested by the motor causing severe damage.

Id like to see how many people this has happened to as well. Post up and what type of throttle body it happened on. Its good info for people looking to get into the ve scene and those already in that might not know better.

I know 2 persons with 2.0 ve that had this happened. I loctite mine already :-)

im thinking the throttle cables not adjusted properly causing the shaft to flex an spit the screws out. atleast thats a possibility.. even though i switched to a highport tb i still made sure my cable was perfectly adjusted.

That doesnt really make sense. The thottle body linkage comes against stops. Its not stopped by the shaft or plate hitting anything that would cause the shaft to flex and spit the screws out.

i guess your right, but ya never know.. its been pretty common knowledge to take the ve tb off right way (or at minimum locktite it). atleast it was when i did my swap 3 years ago

i think this is the main problem. when everything isn't adjusted correctly you will be pulling on the cable when the throttle plate is allready at the stop. which puts extreme tension on the plate itself, twisting the shaft in the middle.

but with that said i have a lowport throttle body and it happened to me! no valve damage but i did have to take the head off to get the piece out. Replaced the valve seals (supertech! ftw) and installled a ve-t metal headgasket on installation.

I believe I read somewhere that it was due to the shaft being composite and not 100% metal. The stop screw jamming against the mechanical stop being we are pushing this motor in our sporty cars not in the auto EcoBoxs that they were intended for I'm guessing it doesn't happen in the car they belong in because no body is hitting WOT everyday. I loctited mine before the motor even went in my car.

^There should be no flex as you can see and this should be the first thing you do to a VE.

P.S. It wouldn't hurt to double check them from time to time. I'll be checking again this weekend since I've taken a few test runs.

It has happed here in Greece to at least 5-7 motors to my knowledge until someone figuered it out and now we locktite every tb we have in VEs. It happend to someone a month ago and preety much distroed the motor as it bent the valve and the the piece got held above the first compression ring so it scrtched bad the cylinder wall along the piston.

I couldn't even get mine loose they were on so tight. I'll check them again this weekend.
