Stripping of V12 Engine Block-Advice please?

[skid]

Hi Guys,

I'm stripping the above for a bit of a fun project as want to turn this aluminium V block into something different such as a wine rack etc. I know it's been done before, but not using a Miura V12!

I have all the steel head bolts (threaded both ends) sticking out of the block as the heads are gone. What is the best way of pulling these out, I'm not saving the bolts so tried a wrench and they weren't shifting!

Also I will probably be taking out the steel liners. What is the best process to do this and does any one know what is behind them on a Miura? ie a perfect bore or holes into the water jacket?

There is also a set of cogs for one of the chains still in place at the top and front of the block. There appeared to be 4 but 1 remains and needs removing. It appears to be held in place by a steel ring pressed into the block holding the shaft, cogs and bearings assembly, all about 4" long. Any techies familiar with this mechanical approach and can advise it's removal???

Thanks Guys.

Anyone???

You can remove the bolts either using a stud extractor, or by fitting two nuts to the thread and then locking them together, then turning the lower nut (which is locked against the upper one) which should make the stud undo. You may find they have used thread-lock on the studs, so a bit of heat followed by wd40 may be in order. !YMMV!

Failing that, cut the studs of at the top of the block with a cutting disk in ye'old angle grinder.(Shudder)

Cant help on the rest, whats wrong with leaving the liners in place?

Tried "a wrench"

If you're not keeping them then stilsons (a wrench ) is the best way to get them out, you'll get a lot more purchase than with either a stud extractor or the 2 nuts method

How knackered is the block ?? I'm suprised it's not worth anything

I tried the wench but she was having none of it!

The block is £k's to repair as had the 'box casing smashed off in an accident. Seeing inside it is amazing as it's a beautiful bit of casting. Going to leave the damege in place as it looks more respectable as 'used'.

I'm going to bead blast it all then have the various decks where parts (heads etc) were attached polished up gently. I need to remove the liners as the bore is quite narrow and won't get many wine bottles in, plus they are rusted to !

It still has all the mains caps and studs in place too. I don't want to damage what is already there, just clean it for display. You never know in XX years time some one might give their right arm for an original repairable block, despite the cost. In the meantime I'll just clean it up and look after it for them!

I'll try the heat and WD40 method I expect, though interested in the stud extractor route. How does it work re adhesion etc? Anyone any other info that might be of help re the liners etc???

Thanks in advance

Skid, where on earth did you get a Miura engine from?
what's wrong with it? as someone else has said, surely it's worth money to someone as it comes from such a prestigious car?!!!!!!

This is a stud extractor (first hit in google)

You put a 1/2" breaker bar in it and turn, the tighter the stud, the harder it grips, Similar to stilsons i suppose.

It's the block and a few external parts of the transmission castings and all from the beloved hallowed halls of Pistonheads!!!!!

It was in classifieds for ages so went for it and got it for a good price. The 'box casing is part of the casting of the block but has been smashed half off at a bad angle. Apparently the guy who had it said it was something like £6k to repair or £7k for a new one (figures distant memory but think correct). Facing the damage and peace of mind he obviously went for a new block.

So I have it for a song. In many eyes it's a lump of metal, in others (mine) it's a work of art and maybe one day someone will have the need to use it properly. In the mean time I will strip the rusting steel work and preserve it perfectly while it houses 12 bottles of Shiraz for me

p.s. anyone want a genuine Miura rear wheel (not studs, a knock on centre spline) whith damaged rim? Cleaned up an interesting office ornament.

Thanks Eliot. Going to tap up a few contacts to see if I can borrow one for the weekend, now that I know what I'm looking for.

It does indeed work the same way as stilsons, they would be a cheaper and easier way to remove the stud IMHO

Got a stud extractor lined up to borrow hopefully tomorrow.

Next job, the liners!

Starters for 10???

I see, as you say the gearbox was part of the block casting and it wouldn't surprise me if the block is a stressed part of the chassis. Think I read somewhere that the engine and gearbox on the pre SV Muira even shared the same oil!!! Surely not a great idea considering the amount of crap you find stuck to a magnetic gearbox drain plug on most engines....

How much do you want for the Muira wheel?

Indeed I believe all Miuras had this arrangement (though I will stand corrected). My block has 4 or 6 inch size holes at the base of the block/'box case to allow free movement through. I guess the sh*t that can build up in engines didn't occur to the designers at the time as these cars would have expected massive amounts of service time and frequent intervals.

The wheel? I don't know. Anyone interested send me a private mail and I'll take a (poor quality) pic with my phone and forward it on. Make a bid as is, or if you want I will get it bead blasted when the block is done (cheaper if done together) and I will add the cost on. It should be fairly reasonable as it's being done by a friend for cash. The wheel is a Campagnoli (sp?) with the centre converted to take a knock on spline.

It has from memory rim damage with some chunks out along approx 6" of the rim edge. When finished and with a nice Miura pic next to it, it will definately something different!
