Dealing with the EGR on a '92 2.3...Is it a B*tch?

Got pre-ignition. Gonna have to go in and clean and test the EGR. Should I stay in bed, instead?

The EGR pipe loves to strip and snap off. If it looks rusty I would be soaking it with penetrating oil for a few weeks

Yes, and warming the engine up helps sometimes too...as well as gripping the pipe just before the nut with some vice grips and holding it in place while working the nut back and forth...

But there is another thread recently about sea foam...it removes carbon that may be adding to the heat in the combustion chambers...that can cause ping/knock too...

Maybe invest in a can of that first and follow the directions...there are YouTube videos aplenty on the web.

Got Seafoam

Thanks, guys. Waiting now to see if Seafoam is the ticket, but I don' think so. Rusty nuts, huh? What happens if it breaks off? Little access to repair it.

When I did mine I had to replace the exhaust manifold bushing, tube and EGR valve.

I got the nuts loose but they ended up wiping the threads right off.

Did one 2 weeks ago and the threads broke off the EGR valve

The first one I did was on my 88 2.0 and I turned the pipe into a pretzel...then couldn't find one for a few weeks...but I managed to actually patch two together once I swapped in the shorty header since they connect differently between the 2.3 and 2.0 so it worked out OK.

Funny thing was, when I broke the EGR pipe (mangled, actually) I thought the exhaust manifold bolts would snap too...but they all came out like they were greased...thankfully!

Just did this last week on my '93 2.3 I removed the valve from the pipe at the intake..didn't remove the pipe from the exhaust manifold..A couple day before I sprayed PB Blaster on all the connections and bolts..had no problems..removed the throttle body to gain acces to the nut on the EGR valve..but not a big hassle...and I'm an old man...lol
