So

The day I load the car on OLX she decides to blow a headgasket.

Apparently the block halves have warped.

Anybody have any suggestions?
New/Refurbished engine?
Go forged while the engine's open?
Current estimate is R20k to redo as is without new pistons or rods.

Might as well keep the fox xt and give it a heart of gold.
What have you done to yours?

If you are going to keep her, then pop some forged pistons in and get the heads and block halves to the engineers.
Cracking the block is going to add quite a lot to your bill though. Are you sure it is the block halves and not just the heads that need work?

Car's currently at ScoobyWorx in Pomona - they're sure and willing to prove the halves have warped.
I know the car ran lean for a while so the pistons are going to be dirty - and might as well fix all the achille's heels while the block's out and open.
Their estimate of R20k includes the work on the block

Yup, ok. Then you need new bearings and pistons.
Then you got a built motor and can add a VF48 and an STi IC
And a tune?
Decat?

Heading out to the workshop tomorrow to discuss all the lekke stuff.
For now the T4 and its fuel consumption is all I need.
STi IC - if I can find one - heard the chinese aftermarket ones are better?
Decat - has a bad little pipe attached to the turbo - still looking for a complete exhaust system/bellmouth downpipe.

There's a budget here lol

judging by the BIG grin in your profile pic, the budget is out of the window, mod the car (for safety reasons) and enjoy!! ;D 8)

There is no mention of the mileage on your Forester. Generally gaskets tend to go every 200 000 kms, although I am not 100% sure about your particular year model.

The gasket on the passenger side of my car went first, although the drivers side one was ready to go any day too. I have removed the heads and measured the gaps and with a 0.05 mm tolerance you can be certain there is going to be some warpage, so best to get it machined anyway. I found a local shop that will do this for R627 each, so quite pleased at that cost component.

Your quote of R20K is pretty good in my opinion. So far, having done the stripping myself, I have spent R2500 on tools alone. After I am done I estimate total cost to be about R 15K (ignoring the cost of cam sprockets I wrecked without the proper tools). The only difference is I may not be able to put everything back together  :-[ and its taken longer than I had hoped.

The XT is just shy of 190'000km..
And well the heads and blocks have been sent to engineering now - was suggested to install new piston rings just to be save. Can't afford forged internals now so I'll just drive stock for another year or so, or try get sold and get a more economic family van.

Would really have enjoyed the opportunity to strip and learn to rebuild myself - but that means buying another car
