    The Nutz About Bolts one? Sorry, I'm not being lazy, it just that sometimes the search tool takes you down different rabbit holes.

    Like BG products, the newest thread is from 2019 which seems weird.

    lol so you're saying my EGR circuit looks like a fossil?

    Thank you sir for the links :)

    And thank you sir for the tip! I'll give that a go first.

    Those two Phillips screws are known to respond well to a hand-impact driver (the kind you whack with a hammer while twisting with your hand), or one of the Lisle or Thexton seized-fastener tools (if you have shop air available). They don't always respond well to much else.

    hmmm will be a challenge then, while I have several hammers I do not have any modern hand impact air tools. Just battery impact screw guns.

    As a newbie, I have quickly gone from "Where are all these threads people say exist" to "this has already been discussed!" in a matter of days. I appreciate Mendel's evangelism and his Bad Flywheel link, which got me to answers better than searching...but it would be nice if we could update the stickies section of this subforum (of course, part of the issue is that "the thread" for some topics is in the Technical Discussion forum instead of here).

    I was able to remove the 2 screws easily with a JIS screwdriver (#2 I believe?). May as well take a peek inside the EGR pipe while you're at it.

    While I'm at it, could someone hurry up and develop a $20 can of oil additive that will eliminate egr clogging?

    that would be similar to creating a synthetic log to burn in your fire place that doesn’t leave residue in the chimney so you never have to hire a chimney sweeper.

    Why hire a chimney sweep when you can clean it yourself? nutzaboutbolts has a video. Just remember, if you didn't clean the little ports in the flue, you didn't finish the job.

    with that being said/ask, let’s go back to your original statement- then why invent an oil addictive to eliminate egr clogging when you can clean it yourself?

    I just wanted to thank everyone for their help and insight, you're all geniuses!

    I didn't have enough time to pull everything apart so I found the pipe, cooler and EGR valve on ebay for $400.00 I paid a shop to switch it all over. lol practically had to beg them do to it. Anyway the pipe was clogged solid! The opening on the cooler was also plugged solid. I didn't pull apart the EGR valve yet, but I'm sure that's not pretty either lol.

    So this cleared the EGR code and the Cat code and I got my inspection done! I spent a little upfront instead of doing it myself and saved on having to replace the Cat which most shops insisted I needed the $1500 factory one.

    I can't believe this car could even run as smooth as it does being stuffed up like that.

    Thanks again everyone!

    I think I'm at 275,000 give or take a few. This car is a masterpiece!

    I haven't messed with the old parts yet, but that's carbon? It kind of looks like soot from a fireplace.

    (y)I hope you saved the old cooler and pipe! They are worth over $100.00.
    Or you can just clean it out when you have some spare time, for the next time.

    If they didn't clean the intake manifold, you've only had half the job done.
    Kinda like changing half the engine oil. The small egr passages in the intake manifold get
    clogged also, kinda like the cooler.... I would get that taken care of very soon.

    I'm glad you were able to get that part taken care of though.

    My bad, I didn't mention it, but I snagged an already cleaned manifold from ebay as well. I mostly got it incase I cracked the original one being it's plastic and the mileage on the car. I did keep all the old parts and I planned to clean them up. The original manifold doesn't look too bad, but it's hard to see inside of it. I haven't checked to see if it can be dissembled.
