Hallo,
Graag heb ik hulp met het volgende probleem:
<img src="[www.mijnalbum.nl];
Voor degene die het (niet) herkennen. Dit is hoe de buis van mijn retourleiding van mijn V8 voor de uitlaatgassen eruit ziet. Niet zo lekker dus. Rijden gaat dus ook niet zo soepel op het moment.
Voordat dit probleem ontstond, was de retourleiding reeds afgedopt. Voor zover ik weet is deze retourleiding niet nodig om de V8 goed te laten lopen. Nu wil ik het huidige probleem compleet omzeilen door de hele buis met roest te verwijderen. Oftewel, ik wil de wartel verwijderen die op de kop zit geschroefd en vervangen door een passende bout. Hierover heb ik een aantal vragen:
* Kan dit zomaar? Alle wartels zijn deze week elke avond al ingespoten met kruipolie.
* Voor welke bout moet ik deze wartel verwijderen?
* Tips of andere suggesties hoe dit te verwijderen?
Graag heb ik advies voordat ik met deze actie begin.
Groeten,
Martin

Re: retourleiding uitlaatgassen V8
Afslijpen bij de bouten die in je cilinderkop zitten en deze dichtlassen. klaar. Klus scheelt als je het hele apparaat uit je kop kunt schroeven.

Re: retourleiding uitlaatgassen V8
Geen idee of ik ook zo'n ding op mijn blok heb, het afbouwen hiervan moet nog.
Maar als ik het tegenkom zal ik het dus zeker weghalen. Ik probeer zoveel mogelijk onzin onder de kap vandaan te krijgen.
afgezien van wat ik er zself weer onderbouw

Re: retourleiding uitlaatgassen V8
Als ik het goed heb, is dat het zogeheten "pulsair" systeem; dat googled wat makkelijker als je er meer over zoekt. Heb een artikel over het verwijderen voor je opgezocht dat ik maar even hieronder plak.

Pulsair on a V8 - How to remove A-Z Guide
Hello all,
This will definitely be of interest to any of you who have Rover V8s with the dreadful “Pulsair†System on it.
This ghastly system was a bodge “Extraordinaire†by Land Rover to gain a low emission rating on the V8 back in the mid eighties, it saps power massively, produces muck in the carbs, and makes the engine gutless and sound as though it has a series of exhaust leaks….
The really good news is that for very little money, and a bit of time you can remove all of this junk, and actually gain a large amount of BHP in the process and a more smooth engine too, …
The even better news is having just done exactly this I thought I would shove up an A-Z post how to do it…
Ok, before you start, you need apart from normal tools etc…
8 of ½ UNF x ½ Allen plugs
These are the plugs that will blank off the eight holes you will have when you remove the pipe work into the cylinder heads, you could even weld up the existing plugs once you have removed them, but I decided for the few quid it wasn’t worth the effort !
Something like Araldite “liquid metalâ€Â, as there will be some holes (2) that need blocking up in the carb elbows..
Right, 1st thing is to remove the carb elbows, and the pipework.
The elbows are easy, the pipes are not, as they have a union which fits into the head ½ inch spanner size, and this causes the 1st prob as the spanner can’t get a good amount of movement – get a pair of biggish and sharp side cutters, and just cut the tubes off as close as you can to the plug in the head, do this 4x and then remove the clamp holding the other end of it to the Carb “telephone†connector, this then removes the pipe and the carb elbow.
On the elbow there is a plug which now stands out proud i.e. where the hose connected to it, grip it with mole grips and he plug will come out, leaving a flush hole in the elbow, repeat exactly the same above on the other side of the V8.
Now using a deep socket you can easily remove all 8 of the cut off plugs to the heads, these come out quite easily, and then simply replace each of these with the Allen plug mentioned at the start of the post, when fitting them shove each in with a bit of thread lock, and do all 8 up tight…
Next are the elbows, I used the Araldite ‘Liquid Stee’l, a 2 pack mix up from 2 tubes, mix a load up, then having cleaning off the inside of the elbow with a bit of a petrol rag earlier I stuck some “tank†tape over the inside of the hole, and then in a vice filled up the outer part of the hole with the mixed compound until flush
Basically you are just looking for a airtight and water tight seal, I have used this Araldite stuff before, it goes off in about 10 mins, and is rock hard in a hour, after an hour remove the tape from the inside and you will see a smooth and airtight seal where the Araldite has gone off.
Do this to both elbows.
Ok, lastly the ‘Push Me Pull Me’ Vacuum. This can be junked, connect the pipe from the RH Carb top to the dissy vacuum, and block off the pipe from the bottom of the carbs, although I haven’t yet the unit in the photo is not needed anymore and can be removed from the manifold and binned.
Lastly the ignition timing, ….on these horrors the timing was ‘Before’ TDC, now with these mods run the timing ‘After’ TDC …..I have about 5 ish degrees, but really as high as you can without it pinking…..
Start it up, and drive it, …………………………..what a difference !
There you go, and not a waxoiled cat in sight !

That's very handy Nige, I think you got BTDC and ATDC mixed up though.

Precies, ik wil dus de bouten eruit schroeven. En, daar wil ik nu juist advies over hebben hoe dat het beste kan.

Re: retourleiding uitlaatgassen V8
Dit systeem is erop gezet omdat dit moest voor de amerikaanse markt. Je merkt geen verschil, wel effe je luchtfilter afdoppen. Ik zaag de buisjes boven de wartels af. Op deze manier kun je de wartels met een dop verwijderen ipv een steeksleutel. Ze zitten over het algemeen niet erg vast. Wartels even dichtlassen en terugdraaien en klaar is Kees (of Klara, als je een meisje bent)
