wow, what an eye opener. Got the intake pulled to do the complete valley service with the kit bought at 928 Specialists....no wonder the car ran poorly, smelled of gas, was a hard start, etc. Two of the larger black hoses under the intake next to the idle stabilizer valve were comp;letely shot...you could put your finger through them.....vacume lines off, fuel regulators leaking...if you didn't pull the intake off you'd never see this. Also doing T/belt, W/P, motor mounts, Nology wires, chip set and re-doing finish on the intake and valve covers but of all that, fixing the vacume problems will probably be the most noticible fix.

Did the same thing on my '88 last year. Major improvment for the engine, felt new again. While your at it, send the injectors out to get cleaned.

 

I haven't used them (yet), but if you're going that route, I have this site bookmarked http://www.cruzinperformance.com/fuelinj.html

 

thanks for the heads up guys....i know the valley 'kit' comes with a fuel injector seal kit...would cleaning the injectors be a necessary proceedure while installing the kit, or do you specifically have to ask that the injectors be cleaned while in there?

What else is in this "Kit" they've got? I've already got my 16V intake pulled and going through the lists of parts from the big 3 to find all the replacements I'm going to need is getting tedious.

 

I sent mine to Marrens ( http://www.injector.com ) The Kit is only the o-ring kit and is nothing to do with actually taking the injector part and cleaning it and replacing the screens. Most places will require that you sent them the kits along with the injectors or they will charge you an additional 4.95 or so.

Just as an FYI, my injectors where flowing at 46cc and had a 10% variance over all 8. After cleaning they flowed at 54cc and all within 1% of each other..

Get them done while they are out... Not worth not doing them..
