cylinder head smog injector problem
 

we have a 912 e with a stripped smog injector. Does anyone have a simple (okay- patch job- the client can't afford to take the heads off) solution? The threads are really down in there and the oe air injector just spins around in the hole now
Thanks!

Air pressurize cylinder with piston at tdc (both valves closed). Drill for helicoil (air pressure will blow cuttings back in your face) - use heavy grease on tap to capture "shards". Aluminum shavings will probably vaporize at combustion temps anyway (1400-1600 degrees).

OR

JB Weld it in.

we'll see if we can get a tap in there- long ways under the sheetmetal
thanks

TRE Cup,

That sounds like John's car (silver-blue E).

Ron,

That is what I like about the board, smart folks giving great advice...http://www.pelicanparts.com/support/smileys/wat6.gif

Thanks Coldbass (ale - mmmmmmmmmmm)

Not smart, just years of fixing broken race cars at the track in the heat and dirt.

The car is a black E with electric windows, tan full leather, Carrera front suspension, polished 7 x15 fuchs all around, H4 euros, fogs, sunroof, dual power mirrors- yep some mods came to her over the years!
The JB weld has set in over the long weekend, and so far so good
thanks again
