[scottyhops]

so i pressurized my system today, turbo'd, and its leaking right on the throttle body seal. there bearings but is there anyway to seal that so it doesn't leak?

Take the TB apart and put a rubber o-ring around the shaft on the outside of the bearing. do it on both side of the shaft . I think i have pics of mine if I can find them ill post

^^^ This. Car will run so much better after you seal the shaft up. I know you can buy the o-rings at local hardware stores for cheap.

His car is speed density so a pre map leak won't effect performance.

These pics just show where to place the o-rings on the 420a TB. You need an 0-ring that fits around the outside of the shaft and place on the outside of bearing.

i did place an oring on the outside of the tb shaft, it only leaks on the spring side though but i can't seal it for some reason

Try placing a very thin washer with the inside diameter the width of the shaft and put it over the o-ring then the spring/shaft over that. I forgot to mention I have a thin hard plastic washer on mine with the o-ring under it.
