tapping noise!!

Check your exhuast manifold gaskets.

One blown gasket sounds awfully metallic for some reason.

I once, not on a LR, had a blown gasket at the head-to-manifold joint on one pot of an engine, I was convinced it was a broken rocker.

Not cylinder liner is it ?

Hope not!! - it's in tomorrow - specialist says he thinks it could be the cats, will know better tomorrow!! I've had a price or £300 for the replacements, delivered inc VAT - does anyone know of any cheaper ?

It's the cat that rattling, don't know if that's good news - but it could have been worse.

And it looks bloody great after having the suspension lift! there were shims under the original springs so he's left them on as well so it's closer to 2". Now for some nice BFG tyres to fill the gap!!

so, you gonna come on an expedition to Pontardawe with it?

Off-road place is reopening this month, hooray. Gonna take the TDi disco down there, we think. Provided the auxiliary belt tensioner turns up. Playing in the mud with a known dodgy tensioner bearing sounds like tempting fate. In order to get the order over 50 quid and thereby get free carriage, I ordered an new pair of elcheapo front dampers for mine. It's taken to being a bit flighty on bumpy high-speed corners of late.

S' four hours down there and that's with the A470 open - it's closed due to the road being washed down the mountain at Dolgellau - off-road centre in Corwen will be visited though.

Ordering the cats tomorrow, after that all should be well !! for a week or two probably.

Oh I've got to find why the drivers seat has about 1/2" backlash witch is bloody annoying - leccy seat so I don't know if it operates on a worm drive, if it does it might be worn.

Sounds like the cats. I took mine off and gutted them. Now I have a better sounding exhaust.

How did you "gut them" aren't they wider in section to the rest of the exhaust pipe they are attached to ?

Please let me know how so I can do the same- I will worry about emissions when it's MOT time.

By smashing the ceramic innards with a long chisel/pinch bar and shaking all the debris out! That's the common method. I did that on a rover 600 I had after converting it to LPG, gave it a lot more mid-range pull. You don't need cats to pass the MOT emissions test if the vehicle is presented running on LPG as the emissions levels and testing method is different. Construction and use infringements are another matter though, but how's anyone going to kinow if they look underneath and see what looks like 2 cats??? Badger.

So Badger was, like

Aye, that would fool anyone. Gluing a hamster to the propshaft has the same effect.

Yes it's on LPG do I just need to tell then to test emissions for LPG at the testing station ?

Yes it's on LPG do I just need to tell then to test emissions for LPG at the testing station ?

Will there be any effect on the engine running if the lambda sensors are bust ? they are in the cat's aren't they ?

Yes - the mot rules at this time state that the vehicle emissions test will be carried out in accordance with the mot testers manual (Bloody big A4 binder!!), in the case of dual fuel vehicles the vehicle shall be tested on the fuel that it is running on at the time it is presented for test. If you book it in for a test and tell the garage it is running on LPG (with direction on how to switchover to LPG when starting, of course) then they MUST carry out the emissions test for LPG, not petrol. If they try and tell you that they either must or will test on both fuels, BULL - that's not what their manual tells them to do, refer them to the testers manual. How do I know all this? I work part time in a garage that does a lot of MOT testing, I've read the manual from cover to cover more than once as I'm about to go and do the mot testers exams and course. Please note, these are the rules as they stand, the government has a nasty habit of continuously changing rules and there's nothing to say that they won't introduce testing on both fuels for dual fuel vehicles at some point in the future. This was banded around the trade recently, but the general concensus is that there aren't enough dual fuel vehicles on the roads to warrant another change in the regulations - at present.

If you've read the book, that is the course When I did mine we spent two days going through the book and asking questions bored the pants off me, third day morning doing the book afternoon in the garage then a one hour exam that a dead hampster can do in ten minutes all multiple choice and they leave you the books to use

the worst bit for me was when the man comes to test you at work he asks you a few questions then gets you to do a test he's not bothered what you find just your routine so remember the afternoon in the garage part of the course

good luck

Yep, I'd heard that said by more than one person before now. But because all my engineering qualifications are within the aerospace industry (Aircraft Propulsion and Airframes systems technician) and VOSA wear blinkers, I have to do the NTTA exam! Go have a look-see at the example questions, there's 2 dodgy ones that even the books by Hillier (Motor vehicle engineering) don't fully cover!

Yep, and the local guy has a reputation for being an absolute by-the-book stickler, what makes it worse is that I know him, and I know he'll be even harsher because of it!

Ta. Badger.
