First off a little history..Got this truck with a knock/tap but with another motor from taurus..I am just trying to get all the life out of the original i can... I gave it a tune up and oil change. Since then I noticed going up hills it'll hit 4k rpms and sometimes i'll get a little cloud of smoke in the cab. I think the cats are clogged could that be the problem? Just wondering if anyone else had this prob?

 

forgot to add that i think its the crankcase breather tube? (tube between valve cover and are filter deal) was off and i put it back together. still doing it

 

cloud of smoke in cab? I think this could definitely be a problem haha.

YES! if your cats are clogged that is/would be a serious problem that will kill MPG and eventually kill you with CO fumes.

 

It's like a puff it doesn't stay or is something you can really notice unless you are paying attention. I'm just glad its what I thought it was and not something else..
Thanks for then help!

 

The head gaskets on a 3.0 Taurus engine are turned around backwards ... that might be your problem there.

 

Yeah we know we have to change it but again that motors not in yet. It's the original (as far as I know) still in it just with a tap/knock.. Apparently the original oil pan gaskets are crap and blow out so whoever had it before me ran it out of oil. My friends a car tech and bought and replaced the gasket added some oil and it still ran so i'm trying to get life out of it.

Now if it is the cats (think so) if i'm right there are 4 of them? What's the best way to do this cheaply in a state that has no emissions?

 

anyone got any suggestions as far as cheapness?

 

punch them out?

 

4 cats?! On the 2008 there is what looks like 2 cats, 1 on each header. but apparently the one is something else not really a catalytic converter. And Then there is just a muffler as far as I know. Probably much more different then yours anyway. But the best opinion I can recommend is to head down to the wreckers and get one

 

yeah you probaly got 4cats 2 small ones and 2 bigger one,cheapest place would be a junkyard,and stay away from the pull apart in cola they never have anything worth gettin
