Best way I know of to find leaks is to hook your compressor hose up to the throttle body inlet (I used the type of rubber stopper that goes into carboys), pump it up with 5-15 PSI, leave the compressor running to maintain pressure, and squirt soapy water everywhere there could possibly be a leak. Engine off, of course. Works well on the exhaust too, only there you stick the stopper in the tailpipe. One surprising place I found leaks was the base of the "black column" breather tube, whatever it's called. Easy to fix. The butterfly valve shaft in the throttle body will also leak. Hard fix. JB Weld? Anyway, it's much easier to see the bubbles come out than try to guess where the air is going in. |
