sorry to hear man. maybe it happened so you can build something even better Gluck Dave

I can't believe all the damage due to a TB plate screw, sorry to hear that DB. Like it has already been said, scary to see all the other similar stories popping up....Good luck with the new build and looking forward to results!!

 

Ouch, man id be ****ing pissed too!

 

This is only the second time I've heard of this...the first was on a MIL Spec but I thought they helped the owner out. It's an old thread, really old I think. Ugh, that totally sucks David *sigh*

 

It seems so common based on this thread, the thread on High Boost and comments from talking to others, it would be a non-warranty issue if it happened to a customer......so check those throttle bodies!

 

At certain areas of exhaust stroke and at overlap, anything downstream can go back up.

 

I haven't looked closely inside my TB. If you pull the upper pipe are these screws easily accessed? Do you need to remove the TB if you want to reloctite them with red? I assume the BR 65mm TBs were assembled with blue in the past?

Thanks.

 

Yes, easy to access and yes, you can take one out at a time or just check that they are snug would be fine.

I think I posted this but my actual throttle body had failed before the screw incident and I never caught it. I'd bet money the screw was an after effect. The more I thought about it the more I should have caught this long ago, I've had a mess of idle hassles for close to a year and I'm sure it was from the shaft snap ring failure and then it just led to this.

 

this was a bad luck david but you make all the forum to check the tb this is best thing i hope the new motor make the same and even higher numbers

 

So, when something like this happens, what exactly has to be replaced? I'm guessing the block, head, oil pump, ALL oil lines, oil cooler, turbo? Everything that has oil in it or is connected to the engine flow?

 

i had 2 Evos in the shop over the years with that type of damage.
always the front side screw were went into the engine and destroyed 2-3-4 in one engine and 1-2 in the other.

2 out of 120 isnt much, but it hurts....

one advise for loctite:
the blue and the regular green ( bearing seat secure ) will became weak over time due to heat and fuel fumes.
also, any type "super glues" doenst hold for long. ( maybe due to the small diameter of the threads.

On high boost cars ( 30PSI and up ) check them regularly and re-loctite them.
Do one by one to not missallign the throttle blade.

i am using an fuel and temperature resistant type of thread secure.
its used for airplane engines, but i did not have any company name, nor product numbers. I know that Airbus uses this, also Boeing and the mayor Engine builders for Airplanes.

this actually happened to my friends supra.. screw backed out of the throttle body but the velocity stacks inside the intake manifold wouldnt allow it to get sucked into the motor.. heard a terrible noise and pulled the head to find zero damage to anything

 

that's a stand up guy right there to make that post.... I respect that a lot in a shop/vendor. Good luck with the rebuild!!!

 

Reading this story just gave me a stomach ache. Seriously!
