[DML] Re: antifreeze in my oil

["Harold McElraft" <hmcelraft@xxxxxxx>]

Antifreeze can get into the DeLorean engine oil from a couple of 
places, all internal, and it is usually not a good sign. Now that 
antifreeze has been into the oil you may already have some serious 
damage. Unfortunately, an internal leak implies some sort of engine 
damage or gasket failure has occurred. Failures rarely lend 
themselves to "stop-leak" types of repair.

Since the engine apparently does not miss, the leak is not in the 
combustion chamber (it would miss, especially at start up, if this 
were the case). It could be a cracked head which could be checked by 
removing the valve adjustment covers or it could be a leak at the 
piston sleeve or liner mount at the engine block inside the engine. 
There are, of course, other possibilities - these are some common 
ones.

If the leak is because of a piston sleeve gasket failure some stop-
leak may work. I would recommend Aluma Seal - I get it at NAPA - or 
any good name brand sealer that works in aluminum engines. I would 
probably do that in any event to see if the leak can be stopped.

I would also drain a bit of oil out periodically to see how much 
antifreeze is still getting into the oil. If you can't stop it you 
are destined, more likely than not, for some major engine repair.
