Fixing a Code 51
Recently my check engine light has come on quite a bit.It comes on as a code 51. Wich is the EGR Circuit. How do I go about fixing this problem? Is there something that I can clean or replace so that the check engine light will stop coming on? Also could you supply pictures if it is something that requires cleaning? Thank you.

Re: Fixing a Code 51
One trick I use to see if the EGR port through the head is plugged is to remove the EGR valve and start the engine up! This will make you hear an exhaust leak which is the flow from the exhaust manifold to the valve. No noise = clogged!
This info may help.................. http://geometroforum.com/topic/678529/ Quote:

Re: Fixing a Code 51
When you get all those parts off, you can start in on where the problem usually is: The passages leading to and from the EGR valve are usually clogged up solid with soot. To get them truly clean you need to remove the intake and exhaust manifolds.

Re: Fixing a Code 51
Thanks for the quick replies. I'll try and get this cleaned and done before I head out to work later.

Re: Fixing a Code 51
If I'm unable to get everything completely cleaned will it cause problems for me? I mean does it hurt the engine to be plugged up like it is? I'm only asking because at the moment it less than nice outside to be out working on the car.

Re: Fixing a Code 51
Does anyone know of any tool that will make cleaning the passages of the intake and exhaust easier to get the carbon and soot build up out? I tried blasting the passages with carb and choke cleaner and that worked a little but the check engine light is still on. Also where does all that crap go when it's getting blasted? And when yoou try and start the car up after blasting those areas it doesn't like it very much. I mean it has an extremely difficult time even turning over. And when it does get going it runs pretty rough until all the cleaner has been burned off.

Re: Fixing a Code 51
I ran into this problem two years ago when I rebuilt The Phoenix.
http://www.automotiveforums.com/vbul...d.php?t=619189 http://www.automotiveforums.com/vbulletin/t622536.html Came up with a tool I used to clean those passageways out. As always - took some pictures. DoctorBill Does anyone use the SEARCH function on this forum anymore ? Do we have to reinvent the wheel every single time ?

The check engine light doesn't go off instantly, might take a couple of complete warm up cycles.
