Porsche996tt

Porsche 996 Turbo year 2002, about 7000km.
I have taken out the engine for a strange noise. I found that one hydraulic Intake valve on the right side was bad; it had a clicking sound when I pushed the valve together. I have taken of the cylinder head on the right side to see if anything was broken. Everything looks good.
I bought too new hydraulic Intakes valves and a head gasket. I installed gasket, cylinder head, valves and cams. After that I went to an authorized Porsche workshop and paid them for timing the cams right. Then we mounted the engine in the car and now I have a New noise in the car. It’s a metallic heavy sound. I can gas up the engine wary slow to 3500-4000rpm, if I gas up fast the new sound appears. I can’t drive the car. No power.
Either wrong mounting cams by Porsche work shop, or can this sound appear if I mount this gasket the wrong way?
Then the Solenoid for Variable Cam Adjuster Camshaft can’t open so the oil doesn’t get through.

What is wrong?

Something's obviously wrong and if there is a right way and a wrong way to install the head gasket and you wonder if you have done this you need to remove the head and check. 'course, that probably means you'll have to replace the gasket with another new one, but that is a small price to pay for a lesson on how important it is to do it right the first time. (Now I'm not coming at you all high and mighty. I've had my share of do overs…)

You can also double check your installation of all the intake hoses but the noise does sound like something related to a lack of oil.

On that note you should not run the engine any more either until you get this sorted.

Wow oil starved or *something*. I wish I had something positive to say or advice but that is the worst sounding TT motor I've ever heard. It can't be better in.person.
I wouldn't drive it, let alone start it in the shape its in.
Good.luck.

STOP IT!! if your starving the car of oil your killing the motor 1 minute of oil starvation is enough to destroy the motor. it has to come out and inspected. the problem will show itself easily

The cam housing gasket cannot be flipped "or" switched from bank to bank.

Looking from the valve cover you should see the embossed writing Bank 1-3 or Bank 4-6. If you don't see it, then you flipped it 180 degrees.

The issue is ZERO oil is flowing to your hydraulic lifters AND no lubrication is going to your valve guides/valve stems..

You will have to pull the engine and remove the gasket. I'd also take a peak at your oil filter for metal..

First when I started the car and heard this I turned it off immediately, I had to make this video just for to hear and see what Porsche or you have any Idea.

The hole to the left on the gasket is for the high lift on the valves I think?

If I turned the gasket the wrong way (like in the new picture) the high lift valve won’t get oil?

If I put the gasket the right way, then it has to be the authorized Porsche work shop that made the timing of cams wrong.

I’m going to take of the Variable Cam Adjuster Camshaft Part# 996-105-303-06-M100. And see if I can see a gasket in the hole, or oil. Hoping I can see a gasket then I know what’s wrong.

Thanks for all suggestions.

my god, that was painful to listen to... worse than nails on a chalk board...

I agree with the suggestions below, definitely sounds like lack of lubrication...but i don't know much

Hi, I have now looked at the gasket and I have not turned it the wrong way, but I was hoping for that. Now the only thing to do is take down the engine and then buy a Porsche 996 turbo timing tool kit, anybody know a good one?????

I'm more and more sure that the Porsche workshop made a mistake when they adjusted the cams last time. Now I have to do there job even after I payed them a lot of money.
