To add to what Configt posted (and thanks for that, I learned a few things being a new R32 owner myself), some get coolant leaks, and I have personal experience with this as I picked mine up aware there was a coolant leak near the rear of the engine.
As we went in, it was obvious all the hoses should be replaced.
If you research this, you'll find many threads, and many are outdated with pics expired, but basically it is usually quite the job, as you need to remove the intake manifold/plenum, and there are tons of bolts and clamps that are hard to get at.
After seeing this done (I actually paid someone to do the job), I seriously think lifting the motor out could be possibly easier.
But for peace of mind, I would just get a full hose set. I got a heater hose set which was the suspected culprit, until we dug in and found it was a hose way in the back that you couldn't get to without removing a bunch of stuff.
We waited for a set from Japan, and in the interim, I found a US based company that has parts. I ordered the full top end gasket set, since there are a bunch of gaskets, having individual throttle bodies etc.
Then we ended up using hoses from Advanced for the actual leak, and replaced all that we could.
Now I see some power steering fluid leaking, so when I get around to it I'll be looking into the HICAS delete.
I have to agree with Configt here, it is a special occasion every time you go for a rip.
Good luck R32_Dreams, and post up when you get one. This was a long time dream of mine also, and well worth the wait
