2.0L SPI engine damage possibilities !!

[piccadilly]

Hi everybody,

I've bought focus 2.0L SPI 2002 and I'm wonder when it will happen to me.

look what I've found on the www.engine-builder.com by Mr Anderson.

Have you ever noticed such problem or heard about it?

"...These engines usually fail for one reason: The engine gets hot and the head spits out an intake seat. We’ve been told that this happens because the fan relay fails and allows the engine to overheat. Once the head gets hot, it distorts enough to break one of the powdered-metal seats into two or more pieces.
When that happens, the pieces beat up the piston and head in that cylinder and then move from hole to hole through the intake manifold until they end up damaging two or three more pistons along with the head before the engine is turned off.

But that’s not the worst of it. After the initial failure, there will be pieces of the seat left in the intake runners and in the EGR passage, so the installer has to completely remove both the intake manifold and the EGR tube from the car and clean them thoroughly or the remaining pieces of the seat will end up back in the reman engine as soon as it’s started. Unfortunately, most installers don’t know about the problem, so they push the intake off to one side and leave it in the car while they’re changing the motor. Then they bolt it back on the remanufactured engine and fire it up, with predictable results. So, rebuilders should hang a big, bright, red warning tag on these engines and make sure their salesman discuss the potential problems with the installer before selling one of these engines – or it will probably fail again and everybody will end up mad at everybody else.

There are lots of these engines out there. Ford has built over 1.5 million of them since ’97, so there’s a growing market for them, especially given the seat problems they seem to have. It’s an easy engine to rebuild and it’s worth doing, as long as you make sure the customer understands that he has to clean out the intake and EGR system if the original engine dropped a seat. Otherwise, it’s not much fun, because you will get to do it over again. "

I appreciate all opinions.

I have never heard of anything about the SPI failing like this, let alone, failing.
