16v_paddy's bent Naples unbending & F7R rebuild

16v_paddy · Nov 16, 2008

Right it's long overdue because of general laziness & seive like memory

but it's about time I get this project thread up & running.
As you all know I was involved in a bit of a nasty smash on 5th Nov 08

and my valver got a busted rear quarter, B-pillar & creased roof :evil: only 2 months after achieving mintness

But this is what happens when chavved up corsas have a go at a Naples :nono::rasp:

But the naples is getting fixed

Here's the latest pics in her current state of bodged repair befor she goes off to the garage to get the brakes fixed then the bodywork sorted and back to mintyness

Now the interesting part........Megane F7R 710 engine to play with :evil: I can't decide between bodies or boost yet, but either way it's getting a forged bottom end 1st and some fancy shizzle with the crank & flywheel.
I'll make the decision when the time comes to buy pistons, but that's only going to happen when the compo cheque lands, and that could be a while yet

I've got a few questions, can anybody tell me what sensors these plugs are for?

I'm assuming this 1 is the oil level sender :S

And what are these 2 for?

Let the fun commence :evil:

f0xy · Nov 16, 2008

i have those two on my megane bottom end (last pic), both cut off the same too!

mini-valver · Nov 16, 2008

1st is knock sensor, last ones just look like earths!

JON13S · Nov 16, 2008

oil pressure switch i believe just has the one wire coming off of it and the piccy below will be the oil level sensor

Sym0n · Nov 17, 2008

Get some full pictures of your car up mate. Looked mint when I came and got that rad.

16v_paddy · Nov 17, 2008

Already up mate

Well I got on with stripping the engine last night

Pics to follow soon

Unfortunately a lack of a T55 bit stopped the fun just short of taking the head off :dapprove:

alex-avfc · Nov 19, 2008

SO glad u are repairing this mate. Absolutely love it

Though I must say, u seem to have no luck at all:dead: wat with the rear quarter before then getting rammed by the Corsa. Best of luck with getting it sorted Paddy

bmh.01 · Nov 19, 2008

As said first is a knock sensor, second the oil pressure switch and the third are just engine earths.

And i'll give my opinion of boost ftw!

B5 BDJ · Nov 19, 2008

boost FTW!!!

nice to see its getting repaired, it was a really nice car.

BOOST is winning me over atm :rasp:

dunlop · Nov 20, 2008

1.8 lump's are the best for boost.

itb's ftw!

Latest Update

Got the car to the garage to get the brakes checked, turns out that all the crap from the other lads car I ran over had somehow knocked loose the goodridge hose at the back & was leaking a tiny bit of fluid, hence the sponginess

So my mechanic nipped them tight again, then bled the system and left it on the pressure bleeder @ 2 Bar overnight. No more leaks, the brakes are s**t hot again

and best of all........He didn't charge me a penny

Wdenesday morning I took my m8 to pick up his V6 from my paint man and left my valver with him to fix :evil: just got to wait for the insurance cheque to land

and I'll have a minty mint valver again

As for the engine strippage, I dropped a bit of a bollock

came to take the sump off and apart from the 6 already chewed up torx bolts

I had the engine bolted to the stand wrong

I had it oriented wrong so could only get 3 bolts into it and 2 of them were into the sump

I managed to sort it out though, pissing around for ages with jacks & blocks of wood

But the fun has to stop for now as I'm back at work on 12 hour night shifts

Back to it on wed though, but I've just bought a 306 XLd with my m8 to fix & sell for some crimbo money so my work on the valver might have to wait but who knows.....

GarethM · Nov 22, 2008

coming along well fella

16v_paddy · Dec 13, 2008

Right, time for an update

not done anything for the past few weeks

had some money making projects on the go

But here's the pics from the stuff I done last time round

Engine in order of strippage

Can anyone tell me if I should be bothered about this rust on the cams, or whats caused it? :S

Cams out

The state of the head bolts, swimming in copper grease

Head off

The block in all its glory

Some not so good photos of the cylinders (piss poor photography skills to blame)

Any educated opinions of the state of the engine would be appreciated

Now the important part of the project so far, the unbending & respray. Just a few pics of the work in progress

dunlop · Dec 13, 2008

tbh you cant really tell from the pics. the bores *look* ok, have a feel around the edge where you can see where the rings have gone up to, and have a feel all around it to see if there is any lipping.

the hone marks look ok, but obviously get it rehoned!

mini-valver · Dec 13, 2008

The bowls on the head look very coked up, nothing a good clean wont sort but I'd check the AFR if you keep the standard flash on the ecu!

dunlop · Dec 13, 2008

tbh, i did think that, but as he was going to turbo it i decided to leave it out as he'll be running a remap.

16v_paddy · Dec 14, 2008

I did notice how coked up the head was & was quite surprised but not too bothered as the whole thing is being rebuilt with new parts & obviously a proper map

I'll be getting a rebore as well, I just need to measure the cylinders to see which pistons I need to get as I don't want to go too far with it unless it's necessary

Haven't got a clue of the history of the engine, hence I got it cheap, but the plan has always been a total rebuild/learning experience instead of just dropping it in straight away

dunlop · Dec 14, 2008

what i'd do mate is get the pistons then give the block and pistons to a machine shop and ask them to bore and hone it to suit them.

16v_paddy · Dec 15, 2008

I've had the bores measured today and the good news is that the block hasn't had a re-bore, it is a bit worn but not excessively, so I'll be ordering some 83mm pistons & getting the block re-bored to fit them

BenR · Dec 15, 2008

thats not rust on the cams, its a band of yellow pant used to indicate that they are indeed 2ltr cams.

16v_paddy · Dec 17, 2008

Update with a Few more pics 8)

Took a bit of persuading with a T50 bit, blowtorch, icecube and a hammer

and got the sump off

Couple of gratuitous oil pump pics, I don't think its very healthy as it doesn't turn very easily and clunks a little bit :S not too bothered as I'm getting a new 1 anyway

Oil pump gone and that gasket s**t is fuckin everywhere

I want a proper gasket for this not the liquid s**t renault say it should be :nono:

Next out was the rods & pistons

Next off was the end caps, I need some educating here

what are these shells/bearings called? I already know the crank big end bearings as they're with the rods, just after the name of each 1

Then it's out with the crank

Next to come off was the oil cooler

I intend to put a mocal cooler on, do I still need to keep the std one? Is it there to help get the oil up to temperature or can I bin it? :S

My nicely organised floor full of engine

I've had the crank and the block measured up and I'll be ordering the rods, pistons, gaskets & bearings etc on monday :evil:

dunlop · Dec 17, 2008

big ends on the con-rods
and the others are main bearings and the half circle things are thrust bearings./

Mark One · Dec 17, 2008

get that block soaking in cheap vinegar

16v_paddy · Dec 17, 2008

I've got that book "1001 uses for vinegar" at home, it would make my day if it said 1 of the uses was for de-greasing engine blocks :rasp:

dunlop · Dec 17, 2008

^ it probably doesn't but trust me it works!

If you've got a lidl near you theres some cheap engine cleaner in there in a spray can, good s**t!

16v_paddy · Dec 18, 2008

It's going to be chemically cleaned when it goes to get re-bored, should I soak it in vinegar anyway??

dunlop · Dec 19, 2008

ah in that case nae bother.

franx · Dec 22, 2008

judging from the pic in the avatar i'm guessing the inlet manifolds of the F7R are different to the F4R inlets are'nt they ?

I have someone who wants to buy mine for a F7R/F7P engine .... Will mine fit this engine ?

**edit** just saw that your avatar pic was taken from a valver.. but my question remains

dunlop · Dec 22, 2008

no they wont fit.

franx · Dec 22, 2008

^^ thanks

Mark One · Dec 22, 2008

yeh but seriously though, 2-4 days in the cheapest of cheap vinegar should be enough to make it sparkle. even without a vibrating bath.
Might be a money saving idea for you.
Looks like it's going well. nice thread

16v_paddy · Dec 23, 2008

franx - dunno if this is any use to ya but also the megane F7R head can't work with a F7P or williams inlet manifold as the shape of the inlet ports are completely different

Latest Update

All the bits got ordered & paid for yesterday

forged rods, pistons and all the other bits & bobs needed for a full rebuild but thats january's money all gone now :S :quiet: and I still need to get a new oil pump for it, I'm now flat broke for the month

but it's well worth it & I'm happy because I got a really good deal

Next part of the project is to get my car back from the bodyshop - tomorrow, can't wait

- then it's mot & insurance time in feb but since I'm working over christmas I'll have a healthy chunk of overtime and a pay rise by then and hopefully enough money left over to get the machining work done and the bottom end built up
