996 injector replacement

Post by Einsteiger » Sun Apr 21, 2019 9:05 am

As the Bhagwan once said: "Paranoia is compleat awareness" :mrgreen:

One item on my SPEEDiagnostics report keeps haunting me: A RED for "fuel dilution" - outside normal limits. Based upon the recent bore scoring videos, the most logical cause is a sloppy injector or two. There are NO symptoms of rough running, missing, etc. I thought about running through a bottle of Techron, like I used to do with my '87 5.6L Benz V8, but the conventional wisdom is that there really is not a consumer-available, add-to-the-fuel tank injector cleaner that works well. Anything strong enough to clean the injectors should probably not be run through the fuel pump.

In typical knee-jerk fashion, I intend to replace the current injectors with new, Porsche OEM's.

There is a great DIY on Pelican for replacing injectors: https://www.pelicanparts.com/techarticl ... cement.htm

The question is: has anyone here actually DONE a DIY injector job? The whole lowering-the-motor aspect has me debating the wisdom of a DIY. The alternative is a $90/hr shop rate, but then it would be done quicker, correctly, etc.

Any constructive feedback is appreciated. Thanks for your time.

Right now I'm going to take my own version of a Sunday Drive and probably dilute the DT-40 a little. :) Side note: I noticed a difference between the new DT-40 and the old Mobil 1.

For some reason I’m just reading this. How did the injector replacement work out? Did your fuel numbers steady out? I also found the Pelican primer right on.

No action to date. Injectors will wait until the next oil sample. Fuel dilution can happen just from moving the car in an out of the garage...without a drive in between...so I’ve decided to set the paranoia on the shelf and drive
