I have a big white box truck, Ford with a V-10 Triton. 70,0000 miles,
1997. E series, was a Club Wagon. In California. I have had for a little over a year and a half. It passed the first smog test just fine. But now it fails with extremly high HC's 1200ppm at idle and
1000ppm at higher RPM. The limit is 150ppm. Everything else passed. The shop said they found one cylinder with low compression 80lbs while the others were around 150lbs. If I remember correctly. They put some oil in the cylinder and it didn't change the compression. So they say it is the valves. I put a bunch of stuff in the tank and oil. Reslon, "Guarentee pass Smog" Stuff and some other stuff that costs around $35.00 for gas and oil that promised everything. It brought the HC's down to 800ppm but that is still way off from 150ppm. I really can't afford to have any work done on this thing. I am still paying for it. I hardly use it. Maybe once a month because of the poor milage. Just to move some equipment. I don't see how anyone can work on this engine. It is packed in there so tightly that I can barely touch the engine. I am desperate. I just need it to pass smog. You really can't telll there is a problem when you drive it. It runs smooth and has lots of power. But I need it for my business. Can someone please give me hope and tell me there may be a way to get this thing to pass smog and how to do it. They quoted me at least $2000+ to work on the engine and I don't have it and I am sure it will be the start of endless work. Like I mentioned I rarely use it but when I need it I have no other choice. I have to move large equipment and it has a lift on it. Thanks for any and all help
