My 02 Deville blew a head gasket today.

I love the car but don't want to invest a fortune in it. I thought of buying a used engine for it.

My question is, is there a millage I should look in particular that would mean that either the
job have been done or it won't happen or then it is a complete guess?

Thanks

How was the HG failure confirmed?

A used engine is potentially a waste of time. It may already have HG (or other) issues, and you won't know until it's installed and running in the car.


No, there is NO average mileage related to HG issues or repair.

The fix (and it's permanent) is to insert or preferably stud all 20 head bolt holes in your existing engine. This can be done for $2,000-$3,000 on average.

HG failure is quite evident to me, ( I think ) low coolant in tank, white smoke in tail pipe and coolant smell also.

I'll investigate deeper tomorrow but !!!

I really like the car, it's roomy, drive nicely and comfy.

Thanks for answering.

keep in mind -
if you are entertaining the idea of a used motor -
it MUST be a "VIN-9" motor -

MOST of the time -
you are better off fixing your motor -
rather than swapping in an unknown -

You didn't blow a HG today. You noticed it today. It failed long ago and slowly got bad enough to notice.

As mentioned, a used motor is a gamble. You might get one that will last forever or you might get one that fails in 6 months. In the words of "Harry Callahan" (Clint Eastwood), "Do ya feel lucky?".

Used engine is a waste of money, I made that mistake as well. If you live near PA I know a master tech who did mine will do it for $1700

:yeah: Block test will tell you for sure. Make sure before you spend a lot of money.

I know fixing the engine is a hard pill to swallow, but just think, can you find a car as nice as your 02 DTS with new HGs and normserts or studs for 3K?

MoistCabbage you are the winner, shame on me should I say ;( but I'm happy !

Finally it was that darn pipe behind the engine, went too fast in my diagnosis, the white smoke from the exhaust was in fact around it. So should get the car back tomorrow or Wednesday, took the opportunity to have the antifreese replaced with new.

Thank you everybody for your expertise ( again MoistCabbage for not taking all for granted )

I'm a proud owner of a Caddy and also to be part of this community !
