Super pics there - look forward to the before and after comparison of the engine bay.

Bring on the next instalment smile - I hope there are no major issues/surprises lurking within...

You’re all very kind. Frustratingly, although I can probably string words together into vaguely intelligible formations, I’ve never progressed beyond typing with one finger, so my rather long-winded posts can take an absolute age to type!! And thank the Lord for spelchequers.......

I hope we discover the sump had been used as a smuggling vessel for an international diamond thief; the proceeds of which OP decides to spend on a couple of turbochargers...

Another brief update. After a bit of a fight, the engine is out. In fact, it may even be stripped by now.



After further discussion with Ricky, I’m now much more au fait with where we’re probably going with the heads. Once off, they will be totally stripped and cleaned. If we replaced nothing else, then the valve springs would be a must. But after years of hammering in and out of their seats, best practice would be to replace the entire valvetrain. Whether or not the valves are renewed, the valve seats will nead to be recut.

Options and pricing: OE inlet valves (20), exhaust valves (20) and springs (40): £1508.40. Supertech valvetrain kit: £1750. The Supertech kit already contains the retainers and valve collets that would bring the price of OE up to the same price as aftermarket. The advantage of the aftermarket kit seems to be newer materials technology resulting in both lighter valves and better heat dissipation. So Supertech it will be then. Seat cutting will be done by the same outside contractor that’ll be doing the sleeving of the block: £400 (that’s £10 per valve seat).

The one unknown here is the state of the valve guides. If worn then they’ll need renewing at £320 (or £8 each) and installing (at the same time as the valve seats) for a further £400 (or again, £10 each). Before reassembly, Ricky will be lightly porting and polishing the tracts to improve the breathing. As standard, the head castings are quite rough and have some ugly steps!



FWIW, the crackle finish to the intake plenums and the air filter boxes will be renewed and then clear-coated in the hope that doing so will aid longevity. The plenums were last done four years ago but the combined effects of heat and rain have led to their current, leperous state.

(And here I can pass on a rather esoteric bit of info that I gleaned several years ago, when I was looking to refinish the cam covers of my F355; the “correct” term for the crackle finish used on exotica is “vermiculated” (from the Latin “vermiculus” meaning “little worm”).)

Great update!
It really does look so similar to the R8 with the engine and bits out

really interesting thread and top marks for providing details of costs etc.

i wondered if by 105k miles any other parts of the car have shown their age and required attention e.g. gearbox, suspension, trim etc?

Having a high mileage Gallardo myself I find this thread extremely interesting. Mine is a Euro LHD so measures in Km's obviously and the clock is currently showing 108k which equates to roughly 67,000 Miles.

I honestly thought I was a contender for the highest mileage Gallardo until I saw this thread!

Mine burns oil too but nothing like yours, I think it does just under a litre per 1000 miles. I had mine de-catted by Sonny at BHP in 2013 so hopefully they didn't get to do too much damage before they were removed, although as my car is an 06 they may have had time to start breaking up.

Thanks again for the thread and I will wait eagerly for the next installment.

You might want to try redditch shot blasting - they are quite well known for re-finishing Ferrari intake plenums as they have managed to find a decent colour and texture match for the OEM red. The website is quite oldskool, but they do a good job - I believe they have done lambo intakes as well, so they should have the right shade and texture.

They powder coat, so it should last a lot longer than re-painting.

That’s a really useful lead. I’ll look into it. Thanks!! (The air filter boxes, which don’t get hot and aren’t under the engine lid louvres are just starting to go, so will also need refinishing.)

This is where you can get the proper Ferrari Wrinkle paint from:
