V10 Valve Job, Lamborghini Gallardo Superleggera| Cylinder Head Valve Removal, Lapping, Cam Install

Let's tear down the cylinder heads that came on the even-fire Lamborghini V10 that came on the Lamborghini Gallardo from 2004-2008. We review how to remove valves from the cylinder head on a dual overhead cam motor We review how to clean exhaust and intake valves of the carbon. We then clean the cylinder head of oil, carbon, and other contaminants. During the final install, we put in new valve stem seals that were leaking oil onto the piston, install the rockers, and finally the camshafts to be put back on the car.

[@jasonbarnes3892]

Wow..

[@TheBullRider]

[@mariodesmo]

I wondered at first why you didn't simply have the heads chemically treated to remove all the carbon and crud. Then I saw the exhaust still bolted on. Yea, those exhausts are another problem for another day! So, 4 valves per cyl, times 10 cylinders equals 40 valves to lap in! Must have had numerous late evenings at the grinding bench 🙂 Looks good!

[@TheBullRider]

Mario, it took so damn long to get those valves cleaned and lapped. On a lot of older audis they were 5 valve per cylinder. So a v8 had 40 valves too..... I couldnt agree more about hot tanking those bad boys and calling it a day. Heck I should have paid them to take that manifold off and put it back on. It would be well worth the $$$!

[@CraigDalton03]

I guess I missed it. Why can't the manifold be bolted off?

[@TheBullRider]

@@CraigDalton03 Craig, the fasteners were so inaccessible that I honestly couldn't find a way to remove the rusted bolts without grinding them off and putting new studs and fasteners on. Since there is no catalytic converter in the manifold, I felt it was best to keep it on and save the pain in removing it!

[@CraigDalton03]

@@TheBullRider Thank you for the explanation! If this was dipped, would they have to be removed?

[@TheBullRider]

@@CraigDalton03 Ideally they would hot tank these heads and would have to remove them yes! Honestly, I would give them the heads with the manifolds on and tell them to get the manifolds off. It would be well worth the money!

[@TheBullRider]

Thank you Buchomodozor, and right on! That was my first Lamborghini too!! :) Didnt have to worry much about the valves on that one either. Hahaha No not the first time, many costly mistakes had to be made before this to get this level of confidence! Haha

[@dalamar6228]

Great video and inspiring! Since the manifold was attached, did the gunk from the exhaust ports contaminate any cats? Or are they not present in that part of the exhaust system?

[@TheBullRider]

That's a great question Dalamar, on the Pre LP there isn't a Cat in that section of the exhaust. However, the LP Gallardo from 2009-2014 has a Cat in that section of the exhaust! If they were present, it would definitely contaminate the cat and I would 1000% take it off in that instance. The LP cars have a revised manifold design that is a LOT easier to take off.

[@adcampo7601]

You're fearless with that car. Would walnut blasting be more effective?

[@TheBullRider]

Adcampo, thats really effective for a cylinder head thats on the car like the FSI motors in the LP Gallardo and the r8 v10 and v8 but what would work best is taking it to a machine shop and having them hot tank it for 30$. But thats no fun!!!

[@Miketime969]

You are a good smart dude

[@TheBullRider]

Mike, thank you sir!

[@alpintourer]

Can I assume red Assembly Lube is NOT generic red Loctite? But Loctite (brand) is a manufacturer of Assembly Lube. Do I have this correct?

[@TheBullRider]

Yes. Loctite thread locker is for fasteners not backing out. Loctite the brand makes an assembly lube that I've never used. This is what I got, its from Permatex. Brand doesn't matter, as long as you got a lubricant on there you are good! amzn.to/36GnEy3

[@carroot7353]

There is far better ways to reco a head, not saying this method is bad at all, on a budget it would work wonders. I work at a engine machine shop in Australia and shops can certainly achieve far better results by thinning out the sealing surface on the valve to valve seat, allows less chance of carbon or any sort of debris sitting under a valve when closing causing compression to leak during operation. Also them heads look ridiculously similar to some of the modern 4cyl vw or Audi heads. Ah yes and then 3 grooved ‘keepers’ put some grease on a stick then put them exactly in place the first try, rotate the first one around and do the second. Good work though, good to see someone getting their hands dirty on a nice car.

[@TheBullRider]

Carroot, you are totally right. The easier and more effective method would be to just give it to machine shop, have them hot tank it, deck it, and machine the valve inserts. But where is the fun in that?!? I wanted to show you that just because this car has a Lamborghini logo, you can treat it like any other car and get an effective valve job at home. You are totally right about the heads looking like Audi heads, the ports are hand polished with clipped valves. So overall its a simple but very effective formula that has been proven to make good power across multiple platforms over the years. Have you ever seen the 5 valve per cylinder heads on older audis like the b5, c5 and d3 platforms? Crazy engineering in those!

[@carroot7353]

OEM Lamborghini PN: WHT000374 2. Audi Alternative PN: WHT001017 The Audi Part number needs a different 12 point XZN socket however. For torque spec and order, check out this video I made. kzbin.info/www/bejne/fqW5mKSkaciBi8U The torque is 30NM, 60NM, 90 Degrees, 90 Degrees.

Haha maybe once or twice Craig! Its always fun to see all the engineering in different engine designs from different models. I typically send the heads off to a machine shop but I thought it would be a lot of DIY fun to rebuild the heads in the garage this time

[@georgedavis332]

Machine the head

[@TheBullRider]

George, what do you mean? Didn't really think that there was any warrant to deck the head in this case.

[@kentadams4589]

I hope you can turn your interests into a profitable business. I know nothing about engines, but have a question. Is that carbon build up because the engine is a direct fuel injection? I can't remember well, but isn't the 458 the first Ferrari with direct fuel injection or am I totally wrong? I have a belt sander that would make quick work of that carbon build up, just not sure it wouldn't take off more than just the carbon build up.

[@TheBullRider]

Kent, always good to hear from you! And thank you, I hope so as well. The goal is to keep providing value to the community and the rest will come naturally. You know more about engines than you think you do. This motor doesn't have direct injection. It has port injection where the fuel is injected ahead of the intake valves. This typically does a very good job at cleaning the intake valves and preventing carbon build-up from the PCV system. This motor is a bit of the exception in terms of carbon build-up due to the failed valve stem seals as you can see. Very atypical buildup for a motor of this mileage. The 430 actually had direct injection in a facelifted version first! Direct injection is great but just like you noted, there are a few downsides. It's the same problem on the 2009-2014 LP Gallardo and all direct injection Audi/VW motors of that era. In the Huracan and a few others, they are now using both port injection and direct injection to further optimize the fuel dynamics entering the motor and to increase volumetric efficiency. Port injection on its own is great though, the Aventador is port injection, and I don't think anyone will argue that the 6.5L V12 in that car is a wonderful piece of engineering! And yeah lets not use a belt sander! A bench grinder with a brass wheel would work great though. Should have done that TBH!
