The V8 Porn Rebuild Thread

[landroversforever]

Quality will live on for a lot longer than the hole in the wallet .

Nige, we need pictures ... even if its a small part you've cleaned up

Oi Ross!! this is a family Forum !! Keep it clean please!!

[landroversforever]

Surely the 'porn' part will keep them out and that's from a mod too

[will_warne]

We've built 4 [Edit: about 10 since you started] or so, does that count?

Smart arse

£1100 isn't bad. It certainly isn't cheap but you are getting quality.....

[ThreeSheds]

We need more pics Nige

My thoughts exactly! When I see the words 'V8 porn' I expect pictures! (ok ok - I realise it's early days yet - I can wait )

Also looking forward the day when this thread has a link to a YouTube "First Start" clip..

Can't wait

Nige, Any upgrades going in the firing line between engine and Simex? How about a nice set of 10 spline axles?

Righty Ho then - mini update

Today saw me 'cleaning' some of the parts up for the start of the rebuild.

Targets for today was the Trumpet Unit, and the Inlet Manifold and Pistons.

When I say 'Clean' I mean clean, not a 'wipe with a Rag' and the "Thattado" stylee

so many seem to think is clean, building an engine of any description, and / or espcially

one in this state of tune is only as good as the condition and cleanliness of the parts used

and similarly the cleanliness of the build itself.

So My standard of "Clean is prob not what many would expect, nor indeed do,

but it makes a HUGE Difference to the finished result and long life / performance of

the rebuilt lump

Also bear in mind the filtration on this engine had failed, and had drawn in dust - and highly

abrasive dust too, this had coated itself to the Valves inlet trumpets etc in fact everywhere

and if 100% of it is not removed then the rebuild would be a waste of time.

My method is to 1st soak parts in the parts cleaner I have (been in their 2 weeks) then remove and

scrub - toothbrushes are good, bear in mind its ali so you must not use anything abrasive - it takes time

to soak into the stuck on carbon / dirt, and also you must not use things that ali doesn't like as you equally damage

the soft ali.

I then find that rags and Brake cleaner / diesel are good to get it off, plus a tin

of FORTE Engine flush shifts some of the really stubbon carbon, sometimes it will come clean easily, sometimes its do what

you can then resoak and do again, this what I have had to do with some of the pistons today - some will 'come up'

next time, some may need a further soak, it shouldn't be rushed.

This is the difference between DIYing it and having a so called garage do it fo you - no,

they will just wipe bits with an oily rag, because your not prepared / or they won't clean things properly L:)

As such the Trumpet base (which had to be fettled back into proper shapes as ding and dents and

prev owners knocking and dented trumpets etc had taken their toll, and 1 trumpet even now (have asked re a new post

in Int ) needs gluing back in - this trumpet alone was 2 hours work reshaping the trumpets etc and then ,

the inlet another 2.5 hrs to get proper proper clean at least I can get a 1.5 inch paint brush

in the ports they are so kin huge ... and the pistons ....I have done 3... so still some to go :

And thats this weekends worth of cleaning results

When I have the rest of the Pistons done, then there are the heads, every bolt washer bracket flange etc is sitting in a

5 litre new Gallon Container of Kerosense and FORTE Engine flush, which I simply pick up shake and place another way up

as I leave the workshoop each time I am in there, when I need to start the rebuild this just gets emptied and the

contents re fettled, but will be 95% mint

In the meantime block is away for liners check core plugs and cam bearings

More soon

Looking good Nige!! As the old saying goes "If a job's worth doing...........get Nige to do it"

Preparation is everything, whether it's your car or DIY on your house.

As you know I'm going to MS my 3.5 bog standard. Do you think it's worth shortening the trumpets at all?

I've heard that about 15mm off each one is about right, or do you think not worth the hastle on a bog standard engine.

By the way thanks for the package , just in the process of planning my angle of attack. Don't want to dive in with both feet just yet

So a quick steam clean and reassembly with an impact wrench is not good practice?

[Anderzander]

Looks gorgeous :-)

[landroversforever]

Looking lovely already!

Nige, can you take some nice hi-res fancy-arty-pants-stylee pictures for my desktop please? cheers

Can do

Like - With a selection of beers and a takeaway in the background

with some hob nobs strewn "Artistically" in the foreground ?

Nige

[landroversforever]

haha if you must

[Bowie69]

Don't forget the jaffa cakes!

[landroversforever]

Nige are you remembering to wash your hands after each cake/buscuit? and before handling anything to do with the engine?

[FridgeFreezer]

Do you think it's worth shortening the trumpets at all?

I'd vote no - lot of hassle, and unlikely to do anything noticable on a stock lump.

Sorry forget to reply

TUP

On a small bore V* (Less than 4.6) waste of time

Shortening the trumpets makes the power shift up the rev rnage

the 4.6cc has the grunt to mask the effects, do it on a 3.4 and things become very very revvy to

get it to got

Combo is shorter trumpets AN Bigger bores right through the manifold - but

then you into serious money, and again the CC size bigger benifit more except

I have seen a 3.4 Rover V8 (sleeved) with big bore trumpets shortened and it reved

like nothing I has ever seen being over square

Buit for the french events by JED

so, answerr is NON

Picking Reliner re Cam bearing'd Block up hopefully Friday, along with new Big Ends, Mains And Ring sets. Have all 8 pistion now cleaned, Can Crank repolished and heads going together, so its coming along in direct proprotion to the £s leaving my account

Pics and info coming soon(ish)

Still cleaning front cover, and triple plenum cover, bought new Genuine Mains Bolts and Cross bnolts, John E advised repalcement (and genuine) as standard best rebuild practise

Nige

[will_warne]

Nige, so you are not using ARP main and x-bolts??? Are OEM bolts really up to dealing with the increased loads of a longer stroke, higher revving bottom end?

[Hybrid_From_Hell]

Nope

A chat with Mr Eales has educated me that you shouldn't / can't fit ARP studs into a Cross Bolted block, the fact

the mains caps are a snap fitmentment to the block means they would be an absolute *** to get on or off.

JEs view is that new factory bolts set and torqued correctly are more than enough, its more the con rods

(These are arrow rods with whizzy bolts) and head studs as well, where he DOES recomend ARPs,

and so it will have them, wel actualy it does already

Nige

[Hybrid_From_Hell]

Just to add I am now a 'tad broke'

Thats all,

Nige

PS But I do have a nice sorted block and other bits

[landroversforever]

Broke... couldnt afford the bandwidth to put up photos?
