Title: Speaking of plugged up EGR systems...
Post by: hcgalvin on April 14, 2007, 08:55:53 AM
Does anyone know where that old article, or informational post (I can't remember which) went, where the guy explains how to clean out his EGR with like a hanger, or something?

Does anyone even know what I'm talking about?

 ???

I can't remember the post. The EGR has a passage that goes through the head at the back of the block. IIRC I had would have had to have the exhaust manifold off to clean it out (used engine no manifolds fitted), that was on a carbed 1.6 so it might be different on an EFI without the mechanical fuel pump. Pic below is the EGR passage from the exhaust side.

Hi Heather,

Mine plugged up at the head end of the steel tube that goes from the EGR valve to the head.  I didn't remove the EGR valve, just the tube.  It's two 10mm bolts on each end to remove the tube. 

The problem is that the port in the head was also packed with carbon, so just clearing the tube won't help.  You have to clear out the passage in the head too.  I just used a piece of copper wire because it was the tool available at the time.  A little Gumout carb cleaner helped too.

But jzap, won't that just knock the crud back into the head where it can cause problems later by blowing back towards the EGR valve.  Wouldn't you have to pull the head to get it all out?

The port goes through the head from the exhaust manifold to the intake side. BTW, Was the carbed 1.6 better than the efi version? it just seems to me that the carbureted version of the 1.3 was a lot more fail proof than the efi (engine computer failure stops the from running). I just wonder if the same is true for the 1.6.

Yep. the best way to clean this is to remove the whatever is connected to either end of the passage through the head and clean/scrub it out with a solvent.  On the exhaust side, that would be the removal of the exhaust manifold. 

Urban, I am not sure that there ever was a carbureted 1.6 engine.  Throttle Body Injection but not Carbed.  Folks like myself run 1.3 heads with Webers/whatever installed on 1.6 blocks.

Debatable, the carbs are pretty complex, similar to the later Samurai carbs. They wear out same as anything else. I don't think the mechanical fuel pump is any more reliable either. I can repair the EFI no problems but finding the right size pipe for all the different vacuum operated functions on the carb is next to impossible  ::).

Its a jungle of VAC lines on the 1.3 sammi engine, and if you have ever tryed to re-build a sammi carb, its a duzy.

Can i clean out my EGR port by just removing the exhaust manifold? Or should i pull off the intake manifold also?

Thanks for the info, guys. ;)

I've had the stupid check engine light come on and off from time to time and the code is always EGR.

I'm just getting tired of it.

Urbanwheeler had the answer to that.  This is the tube to the intake side. 

Most of the blockage was in the tube, whick could be cleaned out completely.  I used a stranded copper wire like a wire brush and cleaned out the head port the best I could.  I also used a fair amount of carb cleaner in it.  This was almost two years ago, and haven't had any further  problem.
