Friend of mine said that. The shop recommended that he replace the water pump on his 996 and he said no. 3 months later the pump failed and bits of the impeller went into the the system which the shop did their best the flush out with no guarantee. 3 months after that his heads cracked and the oil and coolant mixed and now he needs a new engine

99 porsche boxster oil in water been going on for some years only do about 2k a year ( car has covered 97k miles) it has now totally blocked up the system causing overheating. I have removed the thermostat to aid flushing and disconected engine hoses will the block drain without removing the drain plug. The engine still runs o/k but every mechanic I speak to mensions a new engine which would cost more than the car is worth any comments would be appreciated re.Bill

That says it all. Early cars tended to slip cylinder liners and/or crack heads, which requires a total rebuild or replacement.

Once you see oil in the water, or visa versa, STOP DRIVING THE CAR. It ain't going to heal.................

I did mine beginning of the summer, also replaced thermostat and replaced front engine mount. Lots of DIY info out there. with the front engine mount out I was able to get all the bolts off no problem. I did have the care up on stands to get underneath and removed the interior engine cover behind the seats but I would not pay anyone to do it. I don't think it was any more difficult than a brake job.
