Aerodynamics is a weird thing. I replaced my mk2 Golf GTD with a Leon TDi.
"The Leon will be much more aerodynamic" thinks I.
The Golf has a CD of 0.34, the Leon I think was 0.33.
That a sideways wheeled brick is almost as aerodynamic as the Leon, suggests there must be room for improvement.
Get a ball pein hammer, and golf ball dimple the bodywork. :drive2:

I love the wool tufts.
The Americans spent millions on instrumentation, pressure sensors, data loggers etc. to unsuccessfully figure out the supersonic airflows on the B1 bomber.
The Concord designers painted soot mixed with castor oil onto the skin around the intakes to successfully map their airflows. Total cost ten quid.

Back to the car airflow, isn't there a nasty great vortex each side of the car? The one that pushes water up the middle of the side windows when it's a wet day.
Old cars always did this. Some subtle detail by the mirrors or "A" pillars perhaps.

I'm looking forward to the pictures.

Cd is a terrible measurement tbh, the Leon has a greater frontal area than a Mk2 Golf which raises Cd but the front is much smoother which brings it back down.

The side window thing is relatively small and it isn't something easily fixed as there's not much that can be changed that isn't structural.

I've already got plans for the front end so most of my focus is on the back end because... well...

Wasted about 2 hrs on mine today which could have been spent better laying on the sofa watching antiques road trip.

Tried to refit the pcv system back on the car. Replacing the silicone hoses (with more silicone hoses) a po had fitted to it. After loads of time fitting, removing, refitting and chopping pipes it was getting stupid. Hooked up the the catch tank again and shut the bonnet.
Going to order all genuine parts and try again another day.

Give Creation motorsport a ring. They sell silicone versions of the PCV pipes.

Does this help? Part of part 06a-103-247 which is the big fat pipe that goes from the elbow out of the crankcase to the 3 way pipe. Those small pipes are shown along with black valve thingy. check the part numbers on creations page for the part numbers they replace. You also need a PCV check valve. My head hurts now and I need to lay on a couch and look at old things.

Thanks👍
Ok, i built the pcv pipework together as i remember taking it out in 1 piece. But soon realised id have to refit it in 2 or 3 sections.
Nothing fitted well and i found myself having to trim the hose with the built in T piece. I trimmed it where the right angle section from the block goes in and where the little valve goes in. Fitted what i could and found some parts pressing up against the underside of the manifold. So trimmed some more. Finally got it all together to find the pipe that heads up to next to the rocker cover, A) resting on a coolant pipe B) at a crap angle at the top.
Pulled it all out and plugged the catch tank back in.
Im going to order the oe items when ive finnished typing this post.
Items i need are marked in red below. Then everything should fit as SEAT intended.

I had to retrace my steps plenty of times but got there in the end. Some pipes are easier to join outside the car, others you need to push together in situ.
Definitely a job that is best done in two halves with a night's sleep in the middle!

Either the exhaust wasnt hot enough at time of test or the cats knackered.
Is it standard or sport cat?

Those are the best kinds of jobs - when you go inside scratching your head, or struggling to get that bolt threaded, or that pipe reattached, then you wake up the next day and everything just works.

Girlfriend has the car at the moment, so I expect the handbrake ratchets to be worn and that the car's been stalled a few times.

Finger's been hovering over the 'buy' button for a Ryobi impact wrench for a few months now. As I'm thinking about changing the shock absorbers, I'm thinking now might be the time - only that'll be £150 for the impact wrench and £150 for the shocks... I might just stick with the shocks to be honest.

Must admit, for decades I never had an impact driver, thought about it but then most bolts turn with a breaker bar and lots of swearing.... and maybe a little strength.

Then I bought a Dewalt cordless (up to something like 900ish Nm) and I’m kicking myself for not having done it sooner. Think of it as an investment
