distinctiveshinning Posted March 11, 2014 Share Posted March 11, 2014 Please I owned a Year 2000 Mack RD 690S among my fleet. My driver observed heavy smoke containing Gas and Engine Oil coming from the truck exhaust. The truck still runs but not as smoothly as it used to run. My Mechanic initially changed 4 rotors before he discovered from a valve that the problem could be in the engine block. all efforts to carefully remove the camshaft proved abortive because the cup in the engine block is not turning. The mechanic said he observed fragment of mental when the bottom plate was opened and concluded that the engine block is cracked from the inside. That is bad news in Nigeria. Although, I have instructed the mechanic to open up the engine so we can see what wrong, I still want somebody to reassure me that I have not lost the engine block. Thank You.

220cummins Posted March 11, 2014 Share Posted March 11, 2014 "You serious, Clark?"I think you have to be more specific. The RD wasn't available with a gas job. Please provide more coherent Info. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/35009-gas-and-oil-coming-out-of-exhaust/#findComment-236894 Share on other sites More sharing options...
distinctiveshinning Posted March 11, 2014 Author Share Posted March 11, 2014 Sorry, I mean dieseline. In fact the engine oil over gauged due to diesel that entered and mix with engine oil. The Truck is Mack Dump Truck 690S Tandem axle, year of make 2000. I hope some day, I would be able to make my presentation professionally. Thanks.

j hancock Posted March 11, 2014 Share Posted March 11, 2014 Depending on where the "crack" is in the block, you may have created a boat anchor. Quote JimIt doesn't cost anything to pay attention.

distinctiveshinning Posted April 6, 2014 Author Share Posted April 6, 2014 Thanks all. The engine block is intact after-all. The damaged camshaft and cup in the engine block was replaced, engine oil and filters changed and the truck is running well now.

1958 F.W.D. Posted April 6, 2014 Share Posted April 6, 2014 Did you open up the oil filter to see how much metal may be in it? I certainly would. I'd also consider running the crankcase oil about 1000km and then getting a sample analyzed- if you have such a service in your country. If not then I would absolutely change it and the filters- "just to be sure."

Gmerrill0516 Posted April 6, 2014 Share Posted April 6, 2014 2000 seams relatively new to be over there. I suppose they could buy new ones. Does Mack sell into Africa? Probably not too much dealer support. Yikes.
