hi guys im a long time lurker and just joined when I need help. Usually how it goes right?

Any how I have a 2003 focus SE sedan with the SPI motor. recently ive been having a sputtering and it would go dead sitting at idle or first start up but would never throw a code, it would even out after I hit the gas and got going down the road. I had the fuel filter replaced new 8mm motorcraft wires and motorcraft plugs installed and the fuel pump tested. it was fine for about 3 weeks now it came back even worse. Its so intermittent that its hard to diagnose. it finally threw 4 codes yesterday.

The codes are P0304, P0316, P1000, P1117. I think the P0304 and the P0316 caused the other two codes.

any how i have had no loss or gain in fuel mileage after the tune up and no loss or gain of power. I cleared the codes this morning and cranked up up and it idled smooth as a babys butt for 20 minutes. So im stumped any help would be greatly appreciated.

Turns out is the dreaded valve seat dropping on cylinder number 4. Luckily I caught it before it dropped.

I'm at 164000miles and my valve seat was dropping and caused 2 collapsed lifters on cylinder number 4. Been having symptoms for over a month. Now my question is, is $1200 to replace the head and water pump a fair price to pay? I'm not doing the timing belt since I did that last summer

Doesn't sound off for a shop bill to replace all that.

So how did you find out you had a bad valve seat? Did you do a compression test and find it that way or what? I would think stuck lifters would make the car run badly and cause a lot of unusual noise.

I don't think he knew he had one. He just did it just to be careful.

Dennyj1992 was the recent poster who did it as a preventative, bigal06 prob. did a compression test.

Once it gets REAL noisy you've got even more trouble.

I hate to hijack but it's along the same subject of SPI valve dropping. My g/f has a 99 Escort with the SPI. I'm going on assumption but I assume someday this will happen to her car? :/

$1,200 is about right, i think flat rate on a gen1 focus head swap is something like 12 hours or so?? maybe a little less?
ad a water pump in there and that makes it better..

doing one my self i dished out $450 for a short block "as the valve seat dropping turned it to junk" and about $300 for a reman head + $100 for full gasket set.

so remove the short block and that leaves $400 that sounds about right for a shop to charge $1,200 or $75ish an hour or so. leaving out $400 for parts...

when i get around to the next one, ill use a "new, bare aftermarket casting" $216 + all 8 new valves $45 + gaskets $100 thats $361
ill use the cam, rockers, HYD lifters, and springs out of the old head.

being a new casting, thats bare no re-man parts on it. i dont have to send a core back...

For the last month I'd been having misfires at idle and first start up. I did a tune up and it still happened. I finally got a code for misfire cylinder number four and a random misfire. So my mechanic started checking things out pulled the valve cover and I had one stuck rocker and 2 stuck/sticky lifters. Replaced those and still had symptoms. Then I told him about the notorious valve seat issue and he immediately figured it out. The new head and parts have been on for over a week now and absolutely no issues since.

Luckily the seat didn't fully drop I'd caught it just in the nic of time.

Good thing you they caught it on time. Wish I had pay attention to the symptoms on mine.
Dropped the seat on # 2 cylinder split the piston and scorched the wall. A total loss.
Only 135,000 on it. I have a nice red body to get rid of as I am not spending any more money on it.
My advice guys is if you have this engine and plan to keep the car, by all means get the problem fixed.
