Reconnecting the Intake Manifold Ancillaries on an Aston Martin DB9

On By Steve McEvoyIn Advice, How To3 Comments

After you’ve gone through removing and installing your actual Intake Manifolds (like I just did as part of fixing a Lumpy Idle situation) you are in the home stretch of getting your DB9 back on the road.  In this post I will cover reconnecting all the ancillary connections that link up to the Intake Manifolds, things we disconnected along the way and certainly can’t be forgotten.   Some of the steps are just reversing the removal process, but a few have a some technique to them and I will share what I learned along the way with you here.

Installing the Fuel Injectors and Fuel Rails in an Aston Martin DB9

If you’ve had your fuel injectors out as part of a larger project (like me dealing with a Lumpy Idle situation) or maybe you are just changing one (or more) of them, you need to know how to properly prepare and install them.  Your tasks will include getting them properly mated up with the fuel rails again, plus making all the electrical and vacuum connections.   Needless to say – I have a few tips to share.

Installing the Intake Manifolds into an Aston Martin DB9

On By Steve McEvoyIn Advice, How To2 Comments

Without a doubt the most difficult part of changing my spark plugs and coils packs (I was dealing with a Lumpy Idle misfire) was removing the giant and beautiful Intake Manifolds.   Really it boiled down to the huge PITA it is to get to the rear most bolts, but at the end it was manageable.   When it’s time to reinstall the manifolds it would be easy to say “Installation is just the reversal of the steps to remove it”.   In many ways it is, but there are all sorts of tips I can share along the way to make the process go easier for you.

Installing the Spark Plug Covers on an Aston Martin DB9

On By Steve McEvoyIn Advice, How To1 Comment

The spark plugs and coil packs in a DB9 are snugly tucked away under a Spark Plug Cover.   If you’ve had the cover off to perhaps change your Coil Packs and Spark Plugs (as I have been doing as part of dealing with a Lumpy Idle issue), you’ll inevitably need to reinstall the cover.   Doing this isn’t hard, but there are a few tips I will share below to get it done just right.

You may be installing Coil Packs into your DB9 as part of a scheduled service or as part of some other service issue.  I am swapping mine out as part of solving a Lumpy Idle issue (check out my post on this).  Regardless of the reason, getting it done right is important.  In this post I will cover preparing the coil packs plus how to install them properly.

spark-plug-being-removed-from-an-aston-martin-db9You may need to remove the Spark Plugs from your DB9 to replace them at a scheduled service interval or as part of some other service procedure (like doing a compression test or removing the valve cover, etc.).  This is a fairly simple procedure once you have all the preliminaries out of the way, but there are a few  small tricks to it I will share with you below.

Removing the Coil Packs from an Aston Martin DB9

On By Steve McEvoyIn Advice, How To3 Comments

removing-the-coil-packs-from-an-aston-martin-db9Each cylinder in your DB9 V12 engine has its own individual coil pack installed on top of the spark plug right down in the valve cover area.   You might need to remove the coil packs to replace them, or service the spark plugs, or to remove the valve cover or something deeper in the engine.   I’m replacing mine since my car is suffering from a Lumpy Idle (see my post on this).  Removing them is pretty easy once you have the preliminary work necessary to access them out of the way.

Removing the Spark Plug Covers from an Aston Martin DB9

On By Steve McEvoyIn Advice, How To3 Comments

removing-the-spark-plug-covers-from-an-aston-martin-db9The Spark Plug Covers on a DB9 are used to shield both the Coil Packs and the Spark Plugs inside the valve cover.   All this is situated underneath the intake manifolds, so it’s a bit of a phaff to get to them.   You may need to remove the covers in order to change the Coil Packs or Spark plugs (like I am) or perhaps you are fixing a leaking valve cover gasket or something deeper in the engine.   Either way, it’s a pretty simple process.

Removing the Intake Manifolds from an Aston Martin DB9

On By Steve McEvoyIn Advice, How To26 Comments

intake-manifold-removed-from-an-aston-martin-db9The intake manifolds in a DB9 are big and beautiful, blanketing most of the engine bay, so access to anything underneath usually requires removing them.  Some of the reasons you’d need to remove them include changing your Coil Packs and Spark Plugs (as I am doing at the moment).    In this post I am covering the actual final steps of unbolting the manifolds (which is a bitch of a challenge), sharing some tips on how to finagle them out of the tight spaces without breaking off the sensors, and unhooking the unseen vacuum hoses.
