Rebuilt Engine SPI and new Valve Head

So, here is where I am at. My car dropped a valve seat and I got my engine rebuilt total cost came out to $2800. Thats with all all the little things that needed to get replaced once they dropped it back in.

From what my mechanic is telling me is that it's running strong. I would have it now, but while they were test driving it someone hit my car sooo it's getting all sorted out.

My question is, what should I expect of the life expectancy for this new engine with the redesigned head put in. I know before the valve head would drop around 120K, should this run fine so long as I keep up maintenance?

I just did a complete rebuild and a head from headsonly.com and if their claim of fixing the valve seat issue holds true, I expect another 150,000 miles at least. Probably more since the car doesn't see hard miles. Our original valve seat let loose at 120,795 miles. Now the big question is if the car itself will hold up to another 150k+ is another question.

Well everything is as good condition as any car would be at 118k. I'm guessing the transmission would be the first to go if anything. But, my understanding from my mechanic is that everything other than the engine is pristine.

Is there any reason why the engine would only last 150k? I mean the engine was rebuilt an all. Maybe I'm just being optimistic.

Well when I say 150k, that's just what I expect at minimum. In reality, it should be good for a lot more. I just don't give ford a whole lot of credit, truthfully. Been a honda guy my whole life but this focus came along at an excellent price in a time of serious need. The car is a total 9.5 in every way now with a very solid trans, flawless body and new brakes all around. Will be looking into a possible rear suspension issue this weekend and get her back up to a perfect 10.

I guess to answer your question, there's no reason I can think of that it wouldn't last over 150k more miles with proper care.

Apart from the valve seat debacle, the SPI is a very strong motor. If everything was done right, and taken care of, 150k should be easy. There are escort SPI's with 300k plus miles... (basically the exact same motor)

What I would be worried about is the accident. How bad was it. If it was just a minor fender-bender, probably not a big deal, but anything much more than that, and you could have an entirely new set of issues to deal with. (including insurance possibly totaling the car)

Good luck. Hope everything works out well.

yeah our cars seem to be strong. I got 284000k or something close to 176000M on mine. of course with that many k's Im a little worried about the valve seat. I only got my car 1000K ago and dont think the head has ever been rebuilt as im sure the guy would have said something. but other then that I gotta do the brakes and a wheel barring. also my clutch might be dyeing. but for the most part. once those parts are fixed I cant see why i wont get atleast another 150000k out of her. They are strong cars.

I just rebuilt my engine too after a head self destruct at 115K (broken piston, bent rod) - rebuilt / corrected head, new std pistons and rings, water pump, belts, idler, seals and gaskets etc, assembled it on a stand, spent less than $900. and got the car for $800, runs great, superb engine - should last another 150K easy. I know of a running Focus with 290K+ miles on it! Running gear other than the drivetrain (brakes, suspension, wheel bearings) are easily monitored and replaced, and the Focus is easy to work on compared to earlier Fords like the Contour etc. Good Car!
