Just removed my TB to try and do a little more cleaning on the back side of it and DEAR LORD after 100k my uperIM looks like Crap. found Large pieces of carb build up growing off the walls. Was able to clean in there a little but My next project will be to completly remove the UIM to clean it.Car also seems to run a little better now after the small amount of cleaning I did. MY question is, is there a place on the rear bank for a breather filter like there is on front crankcase ? I want to know if ther is any thing else I can do to help keep my intake system clean? (did a search) crap late for class I will be back later!

 

If you have a lot of carbon/soot in your intake, it may be a sign that your catalytic converter(s) are clogged...

 

Do you thnk its the main one or the 2 on the stock y that I am still runing ? that are clogged

 

HEY I AM NOT A NEWBIE ANY MORE wow never thought I would see the day!

 

yea...its kinda cool, no? just yesterday i went from newbie to enthusiast. how does that work, anyways?

 

That's an org secret

Other symptoms of a clogged catalytic would include decreased performance and bad gas mileage.

You can check main catalytic by taking it down and 'looking' through the catalytic converter itself. I'm not sure of about the precats, though.

There are other ways... go look at a Haynes manual of FSM.

 

Is there any way to clean the cat or do I have to get a new one? And is there any other place to put a breather that will help keep every thing clean, PCV maybe?
THANKS FOR THE HELP

 

I couldn't figure it out and felt like I had been a newbie forever. I just got off the newbie status as of 2 days ago. Check this thread, they laid it out for us...

If you know or have advice please responed to the queston above. Thanks

 

You got them going. It takes a bit to stop them.

I dont think there is neccesarily an additive or anything to clean the cat, however it is filter like... maybe you can spray something into the filter to break up the grime? How many miles on your car?

If the catalytic converter is clogged it means the 'block' has melted and collapsed... meaning you need to get a new one.. you can't "recondition" it.

 

getting a 180K service. I think I'll have my intake cleaned/flushed.
Thanks for the advice
