Exhaust Manifold Crack potential fire hazard
I had an issue a few days ago with clogged fuel filters on a Cummins 8.3 L engine .That issue was solved , however the mechanic noticed a cracked manifold exhaust pipe . We discussed it and I was told it would probably be fine until I got back home and that it would be a week until they could get to it.
We left and I asked some knowledgeable friends about it. We'll I took a picture and I was about to show to my friend Earl who has worked on Diesel Engines for many years when he mention how hot the pipe got and how under certain conditions one could get extreme heat ( sparks , flames etc ) coming through the crack. If a oil line happened to be close , it could cause a leak in the line and possibly a fire.
I the showed him the picture I took , and guess what. ? Within 2 inches of the crack was a rubber line that had darkened with soot escaping from the crack !
We are on week long trip with 9 other couples . Right now We are hoping to make some type b of heat shield, to use until I can have the part replaced.. I would like to post a picture but My data plan is almost maxed out. It renews In two days so hope to post a picture then .
In the meantime , be sure and take a look at this occasionally. I am not a mechanic and would probably have never noticed this.
