hello,
I got a ford focus at about 123,000 miles and I'm concerned something like this is about to happen to my car. Sometimes when I start it up it runs super rough. After a bit it usually starts running normal. Also occasionally it does this while driving and it will lack acceleration power.
I don't know a lot about cars but i'm super low on money right now so I was going to try to figure it out and fix it myself. I thought maybe it was a timing belt issue or maybe it needed new spark plugs, but if the engine is about to explode I don't want to waste the money/time replacing a timing belt.

Do those symptoms sound like they could be an indication of this valve seat failing?

thanks

spi valve seat

My car didn't give me any warning,it just lost all power and wouldn't keep running unless I kept my foot on the gas.Then I looked on you tube and found a focus making the same noise as mine, thats when I realized mine had dropped the valve seat. I bought most of the parts on ebay all together it cost me about $500.00 to fix it myself.Yours sounds like it might be plugs, wires, or coil pack. Mine was running like yours and I kept changing the plugs and wires and it would only run better for a short time.Then I was changing the wires and had a trouble light close to the coil pack when I noticed several cracks running the length of the coil pack. I ordered a new coil pack from Advance Auto online to save 20% off the price then went to the store to pick it up. That solved the problem.

We bought our daughter a 2000 Focus SE which had the dreaded valve seat problem. Had hoped my husband could fix the motor and would have the head machined so that it didn't happen again. Unfortunatly the block had a hole in it so we ended up buying a used motor with a good block, etc. We did have the head machined with the correct size valve seats etc...put in all new parts...dropped the motor back in and now we hear a slight ticking noise My husband checked the rod bearings, connecting rods etc and everything is torqued correctly. Does anyone know what could be causing the slight tick?

Thanks! It's running out fine & you don't hear the slight tick at the higher rpm's. My husband is wondering if maybe the lifters need adjusted (if that is even possible on these motors)...

I guess you could say I was really lucky, actually hit 180,000mi before it happened to me. #4 went and it sounded like a hammer hitting my poor engine.

I'm rebuilding a SOHC 2.0 SPI and have less than complete faith in the specifications provided by our trusty friends at Fel-Pro. Could I get a few second opinions on the torque specifications and end sequence for the Head Bolts? I currently have them all at 44 ft/lbs and will hold sequence until a consensus of the SPI gods has been made. Thank you.

Well the motor in my Focus was rebuilt fairly recently. Im guessing this is what happened to it. Or it lost the timing belt...or both.

well im new to these forums, don't know much about the focus till now that im reading this, im here because my girl has an 02 focus never knew this was a common problem, but i guess its good for another while. Her mileage if im correct sorry just kinda thinking top of my head i think is about 38k miles previous owner rarely drove it and she doesn't drive it far just in town so she hasn't even put that many miles in it either and has owned it for almost 2 years. Dam tho now i have lots of reading to do
