Hello, I own an 2008 Xkr 4.2
5 liters of water to make 5 miles, there is water in the engine and many water in exhaust when the car runs. can you help me?

 

Not good my friend!
#1. Stop driving it! Water in your oil is detrimental to say the least.
#2. You've blown a head gasket, so major disassembly and reconditioning is in your future.

 

The car has only 88.000 km from new, Is it possible that the damage comes from water / oil radiator? or that water goes in the manifold? I had cylinder head probems with other cars but never seen too many water in the exhaust

 

What does your oil look like? Is it a brown gray milkshake looking color? Have you drain the oil? How much fluid came out when you drained it if you drained it. Sometimes water spitting out the tailpipe is just a catalytic converter‘s converting that exhaust gases to water so that’s why you see some exhaust spitting out droplets and it’s not necessarily water in the engine. Tell us exactly what’s going on here.

it just could be residual moisture that condensed inside the engine from a bunch of short haul trips. Sometimes it could be car got flooded. Sometimes it could be a bad head gasket leaking coolant. Some of those I listed are bad. Some of those are OK.

 

If you have, or wanna buy, a cooling system pressure gauge, it will help. Attach to where you fill on coolant, pump up. Normally it will keep pressure for at least 30 minutes, if you have leaking head gasket it will drop in max 2 minutes.

If leaking head gasket, and you want to find out which side, buy (sorry) good screw in compression tester, and you can find which cylinder/side is faulty.

If both gauges above show normal, you have a normal cooling system external leak and no need to tear off cylinder heads. Good luck

Always diagnose before you let a mechanic or yourself do major work, saves $$$$$$

 

If it's actually a head gasket, you can buy a cheap chemical tester for the coolant. Since the cylinder pressure is vastly higher than the coolant, a bad HG will force exhaust gases into the coolant. This is chemically detectable. Cheap kit (last I bought one) was $15 or so.

Several other locations can mix coolant and oils. For example, there's a heat exchanger (oil coolant) near the oil filter mount. Can't recall if the ZF uses an air cooler or coolant heat exchanger, but that's always possible.

 

I think you’re in a puddle of ‘Yikes’.
From this dialogue I surmise a trip to the garage on a flatbed is in order.

 

No need to test. This indeed is a head gasket that is long gone… Adios Amigo, Vaya con dios, padre. But what does ur oil look like and also your coolant???

 

Wait , 2008 4.2 SC ? thought 2008 went to 5.0 ?

 

incorrect.

 

2010 is the first year of the 5.0! The guy above couldve at least mentioned it instead of just saying Incorrect.

 

Well, depends on where you are. 2009 in the UK got the 5.0. In any case, 2008 would be a 4.2.

 

true, the US didnt get XKs til 2007 and there are 2006 models.

 

There are actually a few 2008 built 5 litre cars floating around. Here is one that I stumbled across that was for sale in New Zealand.



They will all still be 2010 model year or later though.
