Hello all
I have a 99 cavalier with 2200 engine and the problem is, I heard a sound, like ''clic clic clic'' from the upper egine.
What is this engine sound and what can I do to eliminate this sound ^^ ?

Without hearing it my first guess would be the lifters.
Pretty common for the OHV and 2200, they start to sound like disesl engines with higher mileage... one thing you can do is remove valve cover (when cold or you will need a new gasket)...check the rockers arms and see if any of them are loose, it can happen..also check the studs on the bottom that thread into the head... the sound can also be caused by a bad tensioner, another common ohv/2200 problem... I'm sure a 2200 expert will pipe in with more suggestions.

There is no easy ways to get HP, no magic box or gizmo... And if you get more hp, there's no way to make your car still behave and sound like a stock one. More hp usually makes your car louder, more vibrations and harder to drive...but still people hope or think maby there's some magic way to have it all, comfort, stock sound and drive.
It's common on these motors. Mine in the red 96 is silent, while my old 2.2 corsica, and my other 91 and 95 cavaliers are all louder than hell.
Valvetrain noise.
Goofy thing about the LN2, the oiling priority on it is lifters, cam-bearings, then crankshaft. Yet, the lifters still clatter a bit at cold start-up. Latter years ('98-up, the 2200 as most know it) received a orifice plug in the galley for the lifters to bleed-off air that may (some would argue "would") get trapped to prevent starvation, and prolong lifter life. Still, the clatter does happen when started dead-cold.
Timing-chain tensioner failure does happen... especially in the older S-truck apps. But that's typically not a problem on the FWD apps, as the oil pan sump location effects the lubrication it receives via splash-oiling. The orifice I mentioned installed in later years, particularly on FWD apps, guarantees this to be unlikely to happen. But when it does, it'll be heard in the lower part of the engine, at it's "true" front. And when it does, I highly recommend replacing it with the GM parts, because many of the aftermarket replacements aren't up to snuff. I've seen one fail within 30,000mi on a cheapo rebuilt engine, so I think I can say what I said is true.
It's seems unlikely that the rockers came loose... but, it does happen. It wouldn't surprise me if the bolts that hold the rockers in-place on your 2200, and they just need re-torquing. A service manual can tell you how it's done & how-much to. I suggest also using thread-locker on (blue, I believe) on the bolts to insure they don't likely come loose again.
If you really want to guarantee you never have a looseness problem again, I recommend rebuilding the lifters following the LN2/LT1 lifter internal-spring swap listed in this forum. The higher-tension LT (and even LS-engine) lifter springs will help take-up any slack that might exist prior to oil-filling at cold start-up, thus eliminating any noise that might occur otherwise. Plus, when you go to install higher ratio rockers or higher tension valve-springs, you'll be ready to handle the load.
Also, if you should be able to... or need to... drop the oil pan, install a replacement oil-pump. The Melling M-98 is a popular swap, as it's pressure regulation is set at 80psi vs the LN2's stock 65 or 74. This would ensure that your lifters get filled when the engine's cold-started, so they don't clatter on you. At least not for more than a few seconds.
Follow all these suggestions, and guarantee you'll never need to worry about valvetrain noise again... Because there won't be any!
Go beyond the "bolt-on".
my engine have 205 xxx kilometers ^^
and, how it will cost to be repaired, (in canadian dollars plz)
I will post an audio clip of the ''strange sound''
Well if you do it yourself it will be the cost of the lifters plus all the gaskets necessary to do a headgasket job, as the head has to come off.

Ummm.... the loud valvetrain noise or Disesl sound as it's known is well documented, common, and occurs consistently during engine operation wether cold engine or not.

It's a very common problem, I see posts about it on here all the time, I had this problem with mine and the valvetrain noise I had get pretty loud after only 90,000km..I did drive the car like I stole it all the time, and beat on it like a red headed stepchild.... it was not enough power for the vehicle weight.

I had them come loose, but they were aftermarket, very rare for stock ones to come loose I agree

Wow, it sounds familiar that noise, but worse then what mine sounded like, almost like that's what mine would have sounded like with another 100,000km on the engine...sounds kinda cool actually, like a modded smallblock valvetrain...my noise was most noticable during idle, and was not as noticable during driving but yours seems to get louder while driving...so I don't know if that's the tensioner or the lifters, or both!

up ^^ need to find the problem ^^
Did you check any of the things that the guys here told you to check yet? Pull the valve cover, check the rockers and studs. If they are ok, replace the lifters. If you can't figure it out take it to a qualified repair shop.

P.S. Nobody here can tell you for sure unless they saw it in person and probably did some disassembly.
