Well done - very neat.

I'm jealous of your work space.

I've just discovered I need to fit a new back box, all my exhaust system is still original after 8 years.

However I'm stuck in a LandRover parts wilderness here - nearest exhaust supplier is some 300 miles away - so I've just wrapped it up in some asbestos-type tape until I can find a new one.

Being on relief standby at work is very boring - so the Freelander has been washed and even polished, and I've adjusted, tweaked, torqued, and tested everything that can be t, t & t - ready for the run home at the end of the month.

Singvogel.
 
Thanks SV ;)

it is my place of work, they very kindly let me work on my car (outside my hours)

the rear box is easy to replace, just allow plenty of time to part it from the rest of the system though. I had to warm mine up considerably:eek:
 
I dropped the underbelly protection, drained the oil, removed the bottom of the sump and repaired the hairline crack in it that was letting oil weep through

the repair is setting now - back on the car in 2 hours or so

couldn't get a new gasket so going to take a risk on the old one :)

what fun these freelanders !!!!!!
 
.. to your Freelander today
thinking about it ..

~~~

visited an outfit that makes one-off stainless exhaust systems ..
i fancy a de-catted version with straight-thru silencers ..
nice-man-who-wants-lots-of-dosh said he introduces some back-pressure
.. so as to prevent the turbo from having an overspoolin' stress breakdown ..
( he has previously done td4 exhausts .. 'n does ecu remapping as well ..
( so guess i'll listen to his advice


giving thought to mounting a temp. sensor on the ird-pinion-output-bearing-casing
with an in-cab monitor .. in theory it might warn of impending vcu doom ..
( 3-in-1 Digital Probe Clock Thermometer from maplin ..
( if temp-monitor idea proves useless .. there's still the clock
( which can replace the non-existent lr version in my ve'hicle

.. a covered hippo workshop surely be on my wishlist :)
meanwhile looking for some ramps for 225 tyre width
Car Ramps - Car Display Ramps, Custom Built Extra Long for sports cars and 4x4's, Low entry car ramp for lowered cars
Restoration Car Ramps, UK
or d.i.y. a set made from :
Railway Sleepers Yorkshire - New & Used Railway Sleepers

to do list:
remove undertray screws/bolts .. smear some anti seize grease on 'em
( possibly replace the lot with stainless steel versions .. )
get under car 'n hammerite surface rust

You don't want back pressure!! Turbo or not !! It ain't going to over spool as it's makin 14+ psi ;) It will come onto boost at a lower rpm with zero back pressure system though!! Unfortunately if you de-cat it may fail the Mot!!
 
Today's job is remove the Ird and fit a new set of cam belts to the replacement engine so I can swap it over this weekend!!

mmm .. that's what i thought .. ( but didn't say anything when speaking to the fabricator )
'n figured ecu would cut the fuel in an over-boost scenerio anywayz .. not that it sounds like fun ..
have run hgv diesels with straight-thru-minus-silencer exhausts ( long time ago .. u.s.a. )
non vnt turbos
had no problem .. although redline was only 2200 rpm ..
and any 'potential problem' was turbo temperature related .. not turbo speed ..

Unfortunately if you de-cat it may fail the Mot!!
only if it's visualy inspected .. which isn't done .. a.f.a.i.k.
.. could fabricate a 'false-cat' lookalike .. added expense though ..
the cat sure does smell awful when hot ..
( having said that .. motor runs fine as-is .. exhaust system aint fallin' apart yet
( 'n really was looking at stainless steel for anti-rusting potential
will have to research options i guess :)

.. to the replacement engine so I can swap it over this weekend
hope all goes well .. sounds like a big job ..

I agree about the back pressure.

However it can not fail any MOT due to having no cat as it's a diesel.

When is this myth of MOT failure going to die? :fish:

Singvogel. :cool:

You will be fine fitting a strait through system and will pick up a few Ftlb for the trouble but it will come onto boost earlier which is a good thing. Good luck with it ;)

Alas my V6 is mixing water with the oil again so rather than doing the HG's again i'v got a low miles replacement as a temporary measure which will give me time get the original engine on the stand and do a full strip down to diagnose and hopefully repair it for good??
What we do for our cars!!

I did say "may" ;) it's up to the tester and his interpretation of the rules!!

Sorry - but it's not up to the tester - there is no 'may' about it - the rules are very clear.

So was the memo issued by the VOSA as so many folks were phoning up to check.

Only a spark-ignition engined vehicle has a full emissions test.

Only then does the tester have to check for the presence of a Cat.

If you have no back pressure you can draw oil thru the turbo seals! Which will eventually bugger the turbo! So some is needed but you can have a lot less than normal. Diesels at the mo do not need a catalyst for an mot it's a smoke test not a cat test. No saying the eu won't interfere in the future tho:(

In reality it's pretty impossible to get zero back pressure in an exhaust. A turbo will have more pressure in the manifold up stream from the turbo than there is in the inlet manifold!! This pressure in the turbine housing should be enough to seals from leaking just as it does in the compressor housing.

As for the EU. have you seen this?
