Help Coolant Reservoir

Hi guys I have one little question

PLEASE DON'T TELL ME THAT THIS IS HEAD GASKET ISSUE
Cooling system was drained week ago and replaced coolant.
Recently car had clutch changed with new crank oil seal, replaced cracked oil cooler/ heat exchanger pipe.
in the last three weeks I spent a lot of money to service the car, and if this is head gasket issue then I will be really really SCREWED

Any thoughts ?

Get one of those chemical test kits to check for hydrocarbons. Could just be a bit of gubbins released due to the coolant flush?

Shouldn't this be the prime suspect?

That coolant looks lovely to me.

I presume you are not loosing coolant or oil?

As has been mentioned, if you had an internally failed heat exchanger there may be the odd bit of oil stuck in the cooling system that will gradually find its way to the top. But that coolant looks clean in the pic.

No I do not loose coolant anymore I had an problem with oil cooler heat exchanger pipe that was cracked. Local alfa garage fixed this and they put fresh coolant.
coolant looks ok, no signs of oil anywhere apart form the top of the reservoir. No oil loss neither

that looks like a bit of old rad weld. It hands around in the system for ages and takes a good few flushes to clean it out if someone has put it in, possibly a long time ago.

When I purchased this car about 8 months ago first thing I had to do was changing the radiator (old rad was absolute garbage) before I changed rad I used some halfords radiator sealant for about a month. Do you think that this might be some leftovers somewhere in the system coming out now ?

Almost certainly. Try draining, refilling with a flush product, run it, then drain and refill.

However, i doubt if its going to kill your engine...

I recently had a top end rebuild and noticed a little dark residue on the header tank. I'm assured that it's a bit of oil/fuel in the coolant left behind following flushing, panic over. Apparently very hard to completely flush system.

I still say the coolant looks fine in those pics.

There is a splodge on the top of the reservoir, but that isn't floating on the coolant, it is on the reservoir itself.
So purely going by the pics I'd say stop panicking...

Well I heard a loooooot of people saying " white gunk equals head gasket failure " so I panicked ;-)

But yeah I will buy new coolant and this cooling system cleaner I will flush the system and I'm gonna see if that will help

Thank you all for taking time helping me with this :-)

That'll be "White Gunk (mayonnaise) under the oil filler cap" (small quantity of water mixed into oil causes it)

HG failures manifest with either exhaust escaping into the coolant - it'll boil faster (exhaust gasses are hot!) and a sniffer test will show hydrocarbons in the header tank

The other way is for coolant to leak through to the engine-oil, and end up mixing through that ... that's where the white gunk happens, and shows under the oil filler cap etc
