Head Gasket Issues

I bought my 1997 WRX with a 2004 STI motor last week and it overheated on me. It has reciepts for work a full rebuild and the engine swap less than 60,000kms ago but I think the previous owners knew something was up. Anyway, I was driving around and noticed the AC not getting cold, then saw the temp gauge right up so I pulled over and had it towed to a mechanic after it overheated on me. He diagnosed it with a failed head gasket and quoted me $4400 Aus to fix everything and do the timing belt and everything else top end on it at the same time.

I took my car to a subaru dealership and they told me it was just a leaking radiator which I got fixed for under $1000 as it needs a performance radiator for the 2004 engine which I ordered off ebay myself and they put in. Also got the coolant and oil changed. Driving home it was fine and around town it lasted but as I pulled into my driveway the temp gauge went to 3/4s before i shut it down and listened to the overflow making bubbles, started it up again after it cooled and turned on the AC to smell coolant. I do believe it is the headgasket as the original mechanic suggested because the oil which has just been changed is milky and the coolant also smells exausty.

The main question I am debating is whether or not I should get an engine with 105,000km on it for $4000 and rebuild that with the timing belt, new gaskets ect or risk the current engine I have with potentially warped heads and any other issues it may have since while they are both out I want to rebuild the whole thing to save further issues and keep my mind at ease.

I could be risking the same thing with the new engine aswell so any tips or suggestions would be greatly appreciated as I do not know much other than what I have researched and observed.

Re: Head Gasket Issues

get a sniff test done, to check for gases in the coolant.

Re: Head Gasket Issues

Sniff test is positive.

Would it be better/more reliable to replace the motor with a freshly rebuilt one or would rebuilding my currently one be ok?

Re: Head Gasket Issues

rebuilt is rebuilt really, id ask what a rebuild means to the engine builder.
