Heading to Japan on Vacation

I am packing up the family and heading to Japan for the next two weeks (through August 12th 2017) .   Sadly we are leaving Princess Piddles (my DB9) behind to fend for herself while we are gone.

A considerable number of readers of this blog are from Japan.  If you are interested in touching base while I am in Japan please leave a comment on this article, would be neat to visit and check out your Aston.   I know Japan is a big place and its not likely we’ll be that close, but you never know.  I’ll be in Tokyo, Aikita and Kyoto during the trip.

While on the plane, I plan on starting to write the next group of articles on the interior headliner sagging issue, plus the removal of all the dash panels, etc.   Should be lots of good stuff in the coming weeks.  Stay tuned!


Removing the PCV Valve Assembly Harness from an Aston Martin DB9

Oil build up in the intake manifold

I’ve already explained why you might need to change the Positive Crankcase Ventilation (PCV) Valves in an Aston Martin DB9 in a previous article (usually because engine oil is showing up in your intake manifolds), and what parts you might need (check out this article).  In this article I will explain the process of how to remove the existing PCV Valves along with their harness assemblies.

Parts Needed to Change the PCV Valves on an Aston Martin DB9

If your DB9 needs it’s Positive Crankcase Ventilation (PCV) Valves replaced due to oil buildup in the Intake Manifolds (see my full article on this) then you need to track down the right parts to get it serviced – and that’s what this article is all about.

My enthusiasm for the task led me into trouble (and I can save you from the same mistake if you read through this article).  I wasn’t sure what parts a dealer would normally replace to deal with the oil build up, so I asked the parts manager Rob Sims at HMV England whom I was dealing with.   He promptly sent me the parts diagram, and a list of bits he said they typically serviced.  What I failed to consider was ‘context’, the dealer may be rebuilding an engine and PCV system outside the car, and I was just a newbie trying to do this under the hood on a weekend.

The Positive Crankcase Ventilation (PCV) System in an Aston Martin DB9 – and what Sucks about it!

This is a weak spot in the DB9 engine.  If you’ve ever removed your throttle body and found a puddle of engine oil laying in the intake manifold chamber, the PCV system is to blame.   In this article I am going to give a short background of the ‘what’s going wrong’, and then in the next articles I will lay out which parts you need and how to replace them.
