Hey gang, CNGchat needs your help!

For over a decade we have enjoyed providing this little corner of the Internet for folks to discuss all things natural gas vehicles. It is the largest forum of its kind: with some 70,000 posts on over 11,000 topics. But with continued low gasoline & diesel prices and strong automaker support for electric vehicles, consumer interest in CNG has dropped considerably, and with it has visitor traffic here. As a result, Google ad revenues no longer cover hosting fees.

If you find CNGchat to be a useful resource then please consider making a modest donation to support keeping this remarkable pool of knowledge available to the alternative fuels community. Thanks!

    Can anyone shed some light on a Cummins engine that blew egr cooler, running like crap and blowing white smoke. I replaced egr cooler and checked turbo and checks ok. Any input would be greatly appreciated.

    what cummins do you have? first take your spark plugs out and check compression could have blown a head gasket and be getting coolant in the cylinder or you could have punched a hole in a piston ( could it have run lean from bad egr cooler just a guess) how did you check the turbo they can sometimes still work well and build good boost and have a seal out on the shaft and bypass oil
