Thanks to both of you, I didn't see your reply Blue)(Fusion according to the time on each post we did it at the same time XD.
Yes Mexico does requires an emissions test every 6 months for all cars even in some big cities (Mexico city, Guadalajara,etc.) there are certain days on which your car cannot circulate it depends on the last number of your cars license plate but if your car has a "00" emissions test sticker you are allowed to drive it everyday (it might sound like a mess I know...).
I was tracing the vacuum leak I have, found some vacuum diagrams for the '95 model and there is a tee in it, but I couldn't find it so I went to the dealer for a vacuum hose diagram and compared it to the one under the hood and they are the same, actually they don't show that tee even the guy at the dealer was surprised when I asked for it (I don't know which model will it be the one that does has that tee). Anyway I finally found the leak, it was medium sized leak on the hose between the intake elbow and what it seems to be the EVAP solenoid (I don't know if I'm correct, according to the vacuum sticker under the hood it should be, it is located at the passenger side on the back of the engine compartment near the A/C blower) so I fixed the piece of rubber (it is a nylon hose with a small piece of rubber to attach it to the elbow).
When I extracted that nylon hose it was completely blocked with crap... so I inspected the nipple at the elbow and it was TOTALLY BLOCKED along the entire length, I had to take the intake elbow off and even the horse shoe on that side was blocked, I cleaned it completely until the air could flow freely, I putted it against the light and it's clean now I decided to take a look at the EGR horse shoe and it had a little bit of carbon in it I cleaned too since I was already there... also I took my time to clean the IAC valve. When I started the engine the smell of the air coming out from the exhaust was so different that nasty leak kept the engine running too rich.
I still have to see how much oil is getting burnt, since that vacuum leak took me nearly all day I couldn't run the compression test but I'll do tomorrow. Is there any chance that the vacuum leak could make the oil consumption problem any bigger?
Finally are you saying that any engine from `96 and above will still fit into my car? the intake manifold still fit on place of the plastic model (I know these have a tendency to break) ? Will I have any problems with the PCM or any other kind of problem?
I saw the pictures from your signature Blue)(Fusion, man that engine was clean!
Best regards,
