New to Porsche, C4 mixing oil in water

Recommended Posts

Not knowing where to look for information I started a thread in another forum where I got the advice to ask for help at this place.

So I have traded another car for a dead Porsche 911 Carrera 4 2001. After reading about all the failures I tried to find a new engine but they were very expensive. I figure I should at least find my problem before spending that amount of money.

I guess my first move is to remove the heat exchanger and check if it is broken. Any advice on this?

Would a leak down test show if one of the cylinders are cracked? Would a cracked cylinder cause oil to get into the water?

Another fault I am wanting to investigate is if one of the heads are cracked. Is this visible if I remove the cylinder head with the engine in the car?

If you search for "oil coolant intermix", you should find plenty of info. My 2000 Cab experienced this last summer, and I posted a good deal of information. In my case, the cause was a crack in the head that allowed oil and water journals to join as the crack spread ... resulting in the oil forcing its way into the coolant. In the reservoir, the mixture resembled a chocalate shake.


You can find a great discussion at http://www.flat6innovations.com/index.php/services/intermixed-oil-and-coolant-repairs.


At the time (summer 2014) there appeared to be no new factory engines at any cost. My choices were to pay $10 - 12K to have my engine (a known quantity)  repaired & significantly improved by Jake Raby and his team ... or wait some months and pay close to $20K for a rebuild of someone else's discarded engine.


I have been very happy with the result. I suggest you call Jake and speak with him directly.

Thanks for the advice, the value of these cars here in Sweden is low. It could be that it has reached it low point and will hopefully recover if the proper engine work has been done.

I have done a lot of engine work before but not on this type of engine so I will try to at least find the problem myself.

Started draining the fluids today and I think I know exactly what you mean by "chocolate shake"
