Boiling in the overflow?? Please help!!!
Hi people, I have recently bought a 98 uk turbo 2000. I have been having issues with it boiling up in the overflow tank behind the passenger headlight. I have since changed the radiator as it was leaking, changed the thermostat as the seal was shot, sniff tested the header tank for gases ( didn't change colour at all ) flushed the whole system out and found both banjo bolts on the turbo blocked so removed turbo and cleaned, cleaned banjo bolts and fitted new washers, refilled coolant system and bled out ( as far as I'm aware ) and yet if I take it for a drive for 2 minutes when I pull up it has popped the overflow tank cap off and it throws all the coolant out. I have been scratching my head now for the past three days and can't think of anything else to check or replace other than I havnt bled it out correctly. Could someone please give me some advise and help me sort out this problem. This is my second impreza and im in no rush of selling it so I'm trying to sort the problems out 1 by 1 but this car is my daily. Since i have been carrying out this work I have been using my work van so car has not travelled anywhere whilst this problem has been happening.

The method I use for filling without glugging is here: https://www.scoobynet.com/general-te...t-filling.html it's worked a treat several times for me now.
A sniff tester can give a false negative unless the car has been driven on boost just before. When my head gaskets went the ebay sniffer test did not change colour after a bit of 'ordinary' driving, but changed straight away after a few full throttle pulls in 4th gear to get the cylinder pressure right up, and then testing immediately after at the side of the road. when I took it apart the h/gs were totally shot.
Have you noticed and black/brown sludge or film on top of the coolant in the tank?
Hopefully it's not that and a good refill can solve it.

I will be putting it on level ground when I get home and try it again. If it's the same I will bring my tester home again tomorrow and test it once under boost.

The one that feeds the turbo.
Refill with rad cap off, when fluid comes out re-fit cap.
Then fill header tank to the top,Run car, heaters on full, top up as needed.
I ran mine on the drive till the fans kick in.
Dont forget to fill expansion tank, at least to the min mark

Update : removed the engine and sent it off to a bloke who deals with subaru and has the right equipment for doing the head gaskets, also recommended by a friend. He has today rang me and said number 4 piston is about had it and I have metal files in my oil, so in my head I'm thinking I'm looking on a new crank, pistons ect . . . All of this is not really in my budget right now. I havnt seen the engine but will be going to see it for my own eyes on monday. He tells me I would if been receiving a noise on over run due to the piston, I have been getting a noise on over run but thought it was the gearbox. Does anybody know if all of this sounds right as he immediately ask how much Ide sell the whole car for as soon as he told me this info.
All help appreciated. I really don't want to get rid of the car but trying to find ways round all of this.

Should I just Google Scooby spares? Where is he located? Do you have a direct number for him? Also could anyone tell me how much I'm looking roughly? Mine is a 98 uk turbo 2000. What other engines could I drop in it as in let's say an import engine?
