The most elusive leak yet .. at the bottom of spfi unit where it mates to the intake manifold. There was a little rubber horseshoe looking gasket that let coolant leak as well as vacuum. there was crud that needed a paint remover wheel grinder to get off as if it made tiny wormholes to perfectly leak- it looked like a yellow chalk and burnt stubborn stuff.All while SPFI was tight to intake. Not trusting the original gasket I used silicone good to 400 deg F lightly on base of SPFI as well as gasket.

 

Anyone have better solution? I did clean until surfaces were shiny.I am curious to know if anyone made a gasket out of material worthy. Subaru didn't use silicone there for a reason...:-\

Or better yet for my pursuit of cold air intake.. has anyone blocked off the two ports on intake underneath SPFI and left the coolant line open at back of spfi (to air), and lastly blocked line on heater hose it goes to?

Some allen head screws flush fit and sealed to intake would work, and according to manual, it is just a mini-route riding the bigger one...not necessary for engine's main coolant flow. As for needing heat riser, if this little ea82 got anymore up top end I could fry an egg on spfi unit(All while temperatures read normal- no fluid consumption, etc etc.). I am missing my old carbed DL more than ever.... I could drive for days @ hot outside and casually touch anyhwere on intake for luke warm. The SPFI is insanely too much heat for performance of any realistic kind (I really NEED it). I will post my results if no reply... The cfm gained in cooler compressed air allowed to pass through SPFI (i am guessing) will be a decent surprise.It will be my worst hack yet against an EA82's function (almost sadly)

Ok. All done talkin to myself. As an experiment I put mini-visegrips on rubber coolant line coming out of spfi to pinch it off. Incredible. I tried it out on highway on ramp full throttle, and it never "committed suicide"! 3rd gear 65mph, at about 5000 rpm, letting out a bellow I never thought that little engine would ever have and still pulling rapidly up towards redline. I'm just gonna plug it at back of spfi unit and leave coolant stagnant. It really worked. I am willing to bet I'm pushing 90.1 hp

3rd reply to myself...

Keeping track of what I do to my old loyale (I "strangely" believe it is a classic to be). here is a quick web page of what fixed my prob. I bet it is lurking on many spfi loyales out there......
