help for v belt to serpentine 90 v8

[ANTOINE]

Hi, I would like put this front cover on my V belt engine

but a lot of question and advice

my car is a 90 so I need to know

-what is the good hose for serpentine pump to my 90 radiator ??

-I will keep the admission pipe of the engine's picture , so for the heater, on hose start by the plenium, but after , the return pass by a rigid hose behind the tensiometre belt, and after , where it go ????

-to, I want put my oil gauge on the cover, but on this serpentine cover, there is on out just for the oil signal, how found a second out ?

-can I keep my trigger whell for the new dumper ?

-if you can tell me if the out of oil radiator hose on the v belt pump are the same the serpentine cover ?

thanks, I hope be in the good section

and for the moment I wash all the parts ...........don't be affraid, my engine is on this post for another info

I don't think that you can put a serpentine front cover on a non-serpentine engine if that is what you're trying to do, because the surpentine engine has a longer crankshaft due to the oil pump being integrated into the serpentine front cover.

are you changing the whole engine or just the front cover?

Je ne pense pas que vous pouvez mettre une couverture serpentine sur un moteur non - serpentine si c'est ce que vous essayez de faire , parce que le moteur de surpentine a un vilebrequin plus en raison de la pompe à huile étant intégré dans le couvercle serpentine avant .

changez-vous l'ensemble du moteur ou tout simplement la couverture ?

( appoligies si ce doen't traduire correctement , mais il est un peu difficile de déterminer ce que vous essayez de faire , Google Translate)

[ANTOINE]

don't appologies, you give me a respone ; ) but I think you don't know my engine, this is a 4.6 l , so the crankshat can receive this cover, after this is my théorie from a poor frog eater .........

my problem is for the connection water circuit and oil ( for the gauge what I will keep)

I am agrre , my english is poor, but I try here because, in my country (french, francia, frog guy) , I have not response, so, I try to found an answer in your island ; ) and this your country who buil the LOTUS 7, my dreammmmmmmmmm, if I drive a plate on day, but now, I drive a LR, (and not a Dacia or renault scenic of sheat)

I have done this in "reverse", i.e. put a v-belt cover onto a serpentine motor and it all lined up perfectly. There was no issue with crank length. However, I am not so sure about the 4.6 because that has a completely different ignition system.

The reason I had to do the cover swap, though, is because the serpentine front end on the Discovery motor I was using sat the fan too low in my Stage One (which is fairly similar to a 90 at this point in the chassis) and it just didn't work. I'd check that was not an issue before I got too carried away, if I was you!

[robertspark]

Ahh, yes, with a 4.6 you can directly bolt on the serpentine cover from a 3.9L I think it is (with a distributor port on it).

what is the good hose for serpentine pump to my 90 radiator ??

I think that you could probably (not 100% certain) use a radiator hose from a 3.9L discovery ( I don't think that an efi 3.5 or 3.9L rover was ever factory fitted to the 90 or 110) or else you could use a a mixture of the two ( presume you are changing a 3.5 to 4.6L? so you should have the old 3.5 hose available.

-I will keep the admission pipe of the engine's picture , so for the heater, on hose start by the plenium, but after , the return pass by a rigid hose behind the tensiometre belt, and after , where it go ????

It joins onto the bottom radiator hose. (I'm sorry I cannot find the right part number, but it will look similar to the one in the picture below)

-to, I want put my oil gauge on the cover, but on this serpentine cover, there is on out just for the oil signal, how found a second out ?

Use a "T" piece (just measure your connection sizes and choose the right size)

-can I keep my trigger whell for the new dumper ?

I think you mean "damper"

If you are using a trigger wheel, you are best waiting for Hybrid from Hell (Nige) to advise if you can swap it directly across (I would have thought so).

-if you can tell me if the out of oil radiator hose on the v belt pump are the same the serpentine cover ?

sorry I do not understand what the "out of oil radiator hose" is, are you asking about the oil cooler connections

[robertspark]

Actually, I forgot about the NAS (north american specification) defenders, which did have the 3.9, so there should be a part number available for the hoses to do a direct conversion

[ANTOINE]

thanks a lot Robertspark

I don't think the NAS on your picture have the same cover, but the idea is good I will try to found some thing, I will prefer found the good parts, or jut a picture discovery front cover with this water hose

for the T oil, I have listen, this parts is not very good in aluminium, but like your parts must be iron, I perfer, now, just know if I can put it on the serpentine cover ( little space on this cover), somebody do it ??

for the oil radiator hose, I would like to know if this is the same "plug" on a serpentine cover and Vbelt cover

I hope I am more clear in my sentence

[Hybrid_From_Hell]

You can't swap a V belt front end for a Serpentine front end - period.

The crankshaft is longer on a serpentine, and although I know of a Eales engine where

the crankshaft was lengthened this was done by a specialist machine shop and is not either cheap or easy to do

Sorry, but its not a DIY conversion

[Bowie69]

You can go the other way fairly easily from memory, quite often done for kit cars etc.

[ANTOINE]

Hi guys, don't forget my engine is a 4.6l .................. ; )

and Nige, I will send you a pm for the bracket vr sensor, I think I can keep the treeger wheel on the dumper, but I think I must change vr bracket and edis support,

for info, I am the french guy who try to finish the MS tuning ...........and try to understand all your MS explain ........;but just try for the moment ; ) and I have not much time for the moment

[Hybrid_From_Hell]

Mr Bowie is right,

you can go from Serpentine to V belt - just need a spacer on the crank to make pulley tight

N

[Hybrid_From_Hell]

AH HA !

A penny may have dropped !

You say "Its a 4.6L block"

Well, if its a 4.6 genuine Block than that was NEVER EVER made as a V belt....and will have a 4.6 serpentine crank in it ??

So, is it that you have a serpentine with a V belt front end and want to recovert it to serpentine ??

???

Please advise....

Gents, it looks like he's trying to convert from a 4.6 to a 3.9 serpentine timing cover (with the distributor port on it as shown in the photo) so the changeover should be straight forward.

The questions that seem unanswered are:

1) will the 4.6 fit in a 90 (space for the timing cover, I would have thought so, but not done it myself).

2) can he reuse his trigger wheel on the new damper (now this one lost me a little, because it looks like he's changing from a 4.6 to a 3.9 timing cover with a distributor port on the top, so if he has a trigger wheel, why do you need a distributor? EDIS takes care of the timing

3) (I don't understand this one) : for the oil radiator hose, I would like to know if this is the same "plug" on a serpentine cover and Vbelt cover [what oil radiator hose? The oil cooler?, anyone with suggestions?)

[ANTOINE]

How explain you in the good english

I will try with short sentence ;

I have a 90 v8,

the engine bloc is a 4.6l crossbolted with T liner and his cranckshaft (so long nose)

now , the 90 run with this bloc, a Nigel's MS , and a 3.9l manifold

to, now, the engine have a v belt cover, with the spacer beetwin damper and crancshaft

I have to the tadpole and plug TA preformance for oil pressure

but, I would like try with serpentine cover, because I am a silly (every body understand this, I am sure)

the engine run all day, the car also of course

In the garage :

I have a 3.9l discovery front cover, the last MK1 , this is a serpentine cover and new oil pump, but like you have see, with the diZZY,

as I have the plug on my v belt cover (Nigel complete MS) i can keep it for the new serpentine cover

also my "onlys" questions is, are sorry :

how conected water heater hose, because no issu behind serpentine water pump

if the hose of the oil radiator have the same 'plug" (unf? metric? un ?) beetwin serpentine cover and v belt sandwich plate oil, (like RRC)

if i can keep my treeger wheel, because the crankshaft pulley beetwen discovery serpentine and mine must be the same, I hope

in MY BIG BANG THEORIE HEAD, I think after this I will need just a new bracket VR sensor, and a new bracket edis jumostatic

better explain ? or I am really on the moon ??

if you don't understand, I am sorry, I couldn't do better (or bad ) explain

[FridgeFreezer]

OK, so you've got a 4.6 with the standard (long nose) crank, so it would have the P38 serpentine front end originally.

I assume you have the earlier pressed steel sump, as there are differences with the P38 sumps & oil pickup drillings - you should use sump + oil pickup + front cover all from the same engine.

Nige knows more about the 3.5 / 3.9 setups so I'll leave him to explain those.

If it helps, I converted my 4.6 from 3.5 V-belt setup to 4.6 P38, some photos here: http://forums.lr4x4.com/index.php?showtopic=14579&page=7#entry686353

[ANTOINE]

yes, I will keep the same oil pickup (the early pickup same 3.5l) because on the serpentine front cover i have, this is the same, and the sump is the same to, not like 4.6l serpentine who have the sump not plane on the front

[ANTOINE]

as you can see MR FF, this cover (serpentine 3.9l disco 1) , I will can keep the sump and oil pickup, I hope picture is better my explain

on this one, the oil pickup stay on the middle of the block and not on the cover

we can see the difference with a 4.6 genuine front cover who are more fine and where the pickup is on the front cover

I think LR do this one for test oil pump ? or because they wait the gem's ecu ??? or they have too drink saturday evening ??????
