P38A V8 De-Catting advice

Yes, same wording here: http://www.dcrobinson.co.uk/media/MOT Manual Complete - 201701.pdf

"7. Multi fuel vehicles Vehicles which run on more than one fuel(e.g. petrol and LPG) should be tested on the fuel they are running on when presented."

Im just repeating what the MOT tester told me.

If the vehicle is presented running on LPG it requires no emissions testing, no reading with the gas analyser.

The fact is that even with the cats removed it will still pass an emissions test on LPG.

What will happen if you take it in and 'your' tester has pulled a sickie ?

Will the other guy pass it ?

Incorrect. I doubt it will pass a cat test with cats removed, but it would pass a non cat test ( which it would be tested on if it were a pre cat classic )

Ok thanks guys seems I found a very unique place to take it for an MOT. Glad I posted this, apologies for being misinformed!

New plan now to keep the cats, chop them just after and attach with a couple of flexi pipes to this custom 2nd hand stainless system I’ve bought.

Does anyone know if the studs at the manifold to downpipe join are pressed in or reverse threaded? 2 of the 6 snapped and I need to get them out.

From memory they're just total f*ckers. Lots of Plusgas and heat.

They are threaded. Easiest way to sort is remove the manifold(s) and do it with manifold in bench vice. Lots of heat, lubricate, heat, lubricate, and eventually they will move with mole-grips. If they snapped flush with manifold then you're gonna be drilling, or finding replacement manifolds.

For next time ...
Use lots of GT85 or whatever penetrating fluid is your fav, drown the bastids everyday for a week .... then start the job ...

I've never snapped one yet !! .....

We did. Bloody nightmare.

I think mine are welded all of them. I hope there threaded though. Two are ruined it'll make drilling them easier.

Ok nice one big fan of plusgas, luckily it’s just one bank and 2 broken studs with some meat left on them, surprisingly similar to that image. Looks like I’ll have to take the manifold off then

Seem to remember the heat shield bolts being utter barstewards too.

Got that to look forward to as well! Does anyone know what socket I need to remove the manifold bolts, part no ERR4961.

They are a spline head pattern I’ve not seen before.

Cheers

a standard socket from my halfrauds set took mine out and adams when we stripped his heads off seriously that rear stud at the back will be the biggest issue oh and the heat sheilds bastard things

Put a pic up sounds like bi-hex ...

It is bi hex. Easier to remove the intermediate steering thingy after removing the wheelarch thingy. Of course neither of these are easy!

Yes, might need a second person to wriggle the steering wheel to get the intermediate steering thingy off.

You don't need to remove it, its 1 less thing to mess about with so leave it alone
