This is what teenagers call a "zit" in the USA:

So, what is it called in your part of the world?

Hi Srecko, it's a little joke - I hope Google's translator works in Serbian:

àêíè áóáóšèöà

(I guess it doesn't) let's try Croatian: Acne bubuljica

Looks like a play on light. There is dark camo under a light patch of camo. Either that or it blew a jug off and it didn't make it out of the cowling.

This is a Genuine blister for something. I don't have much on FW 190's but I do have two books with cut away drawings but of later versions than this which is an A-5/U8, Aeroplane did a Database article on the 190 just a few months ago IIRC? I have the issue just give me a couple days to dig it up to see if I can find any more info.
wiki sez:

Fw 190 A-5

The A-5 was developed after it was determined that the Fw 190 could easily carry more ordnance. The engine was moved forward by 15 cm (6 in), and the aircraft was equipped with the BMW 801 D-2 engine, rated at 1,700 PS (1,677 hp, 1,250 kW). Some A-5s were tested with the MW 50 installation: this was a mix of 50% methyl alcohol and 50% water which could be injected into the engine to produce a short-term power boost to 2,000 PS (1,973 hp, 1,471 kW), but this system was not adopted for serial production. New radio gear, including FuG 25a Erstling IFF and an electric artificial horizon found their way into the A-5. The A-5 retained the same basic armament as the A-4. The A-5 too, saw several Umrüst-Bausätze kits. The U2 was designed as a night Jabo-Rei and featured anti-reflective fittings and exhaust flame dampeners. A centre-line ETC 501 rack typically held a 250 kg (550 lb) bomb, and wing-mounted racks mounted 300 L drop tanks. A EK16 gun camera, as well as landing lights, were fitted to the wing leading edge. The U2 was armed with only two 20 mm MG 151 cannons. The U3 was a Jabo fighter fitted with ETC 501s for drop-tanks and bombs; it too featured only two MG 151s for armament. The U4 was a "recon" fighter with two RB 12.5 cameras and all armament of the base A-5 with the exception of the MG FF cannons. The A-5/U8 was another Jabo-Rei outfitted with SC-250 centre-line mounted bombs, underwing 300-litre drop tanks and only two MG 151s; it later became the Fw 190 G-2. A special U12 was created to fight American and British bombers, outfitted with the standard 7.92 mm (.312 in) MG 17 and 20 mm MG 151 but replacing the outer-wing 20 mm MG-FF cannons by two underwing gun pods containing two 20 mm MG 151/20 each, for a total of two machine guns and six cannons. The A-5/U12 was the prototype installation of what was known as the R1 package from the A-6 onwards. The A-5/R11 was a night-fighter conversion fitted with FuG 217 Neptun (Neptune) radar equipment with arrays of three antennae vertically mounted fore and aft of the cockpit and above and below the wings. Flame dampening boxes were fitted over the exhaust exits. There were 1,752 A-5s built from November 1942 to June 1943.[20]

Especially for Prom Zit or bubuljica

When I finally unpack all of my aviation books after moving I'll find the book that mentions this blister. I seem to recollect its from either moving an engine accessory or the exhaust itself due to overheating problems with the BMW 801. This happened more often in the earlier models (A-3, A-4) until they finalized the exhaust routing.

Can you send me scan please?

If you have access to the Osprey FW 190 Aces Of The Russian Front the first chapter speaks to the development problems with the FW.

I do recollect a picture of the cowl blister in there somewhere...could be the water injection unit mentioned in a previous post.
