pressurizing to test for leaks...?

sen2two · 08-27-2009, 06:30 PM

put the new grommets in. fixed the leaks there, and no more leaks on the throttlebody either. so i thought all was good. But there is still a major leak somewhere underneath the manifold...

I cannot see or feel anywhere under there. I was lucky enough to see the primary injector leak the 1st time. So, i removed the upper manifold for about the 30th time in about 3-4 weeks (not exagerating). i checked every single place air could escape. One oil injector was semi-loose. but i think it was still tight enough to seal. So, i have no idea where the air is escaping...

anyone have any ideas to check for leaks with the upper manifold off? I been adding the pressurized air at the throttle body. so with it removed, i will not be able to do that.
