Pull off the air hose and poke at/look at your turbo.

so im going to try to keep car-put straight pipe in with a used turbo.i think it must be a royal pita to get turbo out,i have some info from maual,but input is welcome.

do you think alda off contributes to plugging up cat?

Pulling the turbo isn't a huge deal, just take the air filter stuff and inner firewall out of the way first, and the belly pan if you have one, everything is at least in reach/view.

Someone posted pics of a plugged cat on here... search around for it if you feel. I am sure there are a few reasons they become plugged... blowby, people driving slow, EGR crapola, etc.

I have no idea of the laws specific to your state. I believe CA just does a snap test for Diesel vehicles so as long as you do not have a huge cloud out the tailpipe you should be fine.

What does that mean? I would gut it/remove it/etc. Gutted passes a visual, just a piece hacked out will not.

hitmanx you nailed the problem and led me in the right direction-2 burgers fries and onion rings.


as to recall ,trap ox was already recalled and replaced with straight pipe and cat.car runs better without cat and probably cleaner.
