Tips Requested: Remove Fuel Injection

der Mond · 07-03-2006, 11:31 AM

I have a new set of engine compartment flexible fuel lines and fuel injection manifold gaskets to install, and have not been able to find posts regarding any tips on removing/reinstalling the fuel injection manifold system as simply and painlesslessly as possible. Tips would be appreciated. Also, after reeassembly, since I'm 400 miles from the nearest dealer, can I have any shop that does emissions inspections check my CO? What are the allowable limits?

Don't know the answer, but to help you get one I'm bumping your question back to the top.

I've haven't done this task on your exact engine but a few suggestions (warnings): (1) account for every fastener element (nuts, washers, etc.) and have them off the engine before lifting the induction manifold- no dropping a fastener and finding it later (find it immediately - a magnet on a stick is your friend) as you risk having it fall into the engine, (2) immediately plug the openings into the heads as soon as you lift the manifold. A set of 1/4" drive sockets with integral universal joints and an assortment of drive extensions is very helpful in accessing fasteners on the top of the engine. A partial engine drop may be helpful/required to improve access. Hopefully you will get better more specific input from others.

Thanks for the replies thus far.
Thanks for bumping the thread!
I visited friends in Everett back in the 80's and used to ride a bike down to Mukilteo and watch the cars unload for Whidbey Island. It was then a quiet, pretty place. Wanted one of those license plate rings - "My favorite place: Mukilteo by the Sea."
Saw it a few years back - it will never be the same. But that's how it is these days - by the time the gasoline formulation developments go, my Porsche may never run the same also. But I hope to have a couple more great years with it.

I did this job a little bit ago to replace intake gaskets. It's basically 'just keep taking things off until you can remove the intakes'. Fairly time-consuming, but fairly straightforward as well.

Start with the passenger side as that is fairly easy to remove; once you get it off you'll have more room to work on the driver's side.

Jim is right (as usual) on the fasteners thing. I carefully put every nut and bolt back where I removed it from as I took pieces off the engine. That way there's no question about what goes where during reassembly.

Good luck,

This is not too tough, but it will take you some time. Get a good u-joint for your ratchet to get a the barrel nuts that hold the intake manifold on. You do not want to strip one of those.....

I would suggest you replace the insulator blocks between the two gaskets, it has been my experience that this is where a majority of the intake leaks occur.....

I also am sending you a PM....

If you are removing the fuel injection to gain access to the fuel line in the rear, drop the engine.

I removed my f.i. to replace gaskets and oil sender and it would have been faster just to drop the engine.

I secons what Jim said, have a tool to retrieve washers and nuts, plug your intake holes, and make sure it is not windy.
