YesWhat engine arrangement do you have? RC?

You mean having the cam followers riding on the balance shaft would cause a problem?A guy i used to know tore down a 6-71 and slapped the head back on and found out when he went to set the valves and injectors that he had the head on backwards. There may have been a little bit too much whiskey imbibed during reassembly between him and his helper
Are the major components arraigned like the engine it is replacing? Blower and exhaust manifold?I dragged home an old 471yesterday, we will see what shape it is in, I think I will pressure test the cooling system first thing
Yes a couple of things different, like front motor mount and governor, fuel filter location , all in all pretty goodAre the major components arraigned like the engine it is replacing? Blower and exhaust manifold?
those should not cause major problems as they should be good on the original engine.Yes a couple of things different, like front motor mount and governor, fuel filter location , all in all pretty good
You post this almost every time some one post a DD quiz so exactly how many engines have you seen that were defiantly "murdered" by using 15W-40 oil?Sounds like you're on the road to getting it going again, hope the replacement engine works out well. If you get it going, whatever you do, don't use 15W-40 in that engine, that oil will murder a 2 stroke Detroit.
There is plenty of documented info out there Bluox, including from Detroit Diesel themselves recommending to not use multi viscosity oil in those engines, although this info is becoming a bit antiquated as these engines haven't been a part of the mainstream for many years now. Yes, I know, I post this every time I see a 2 stroke Detroit post, trust me, I take no pleasure in this repetition, but I'm not the message, just the messenger, the documentation is out there. Myself, yes, I've seen plenty of 2 strokes back in my day that had serious piston, ring, and liner failures, although I could in no way prove that it was caused by those engines were using 15W/40, which they were. But one I have seen that perked my spidey senses, an 8V-71 in an Ingersoll compressor, smoked like the woods was on fire when we got it. I dumped the oil, added straight SAE40 Delo 100, the more we ran that thing the smoke problem from the exhaust cleared up. Anecdotal? For sure it is, but it sure gave credence in my mind to what Detroit Diesel recommenced in those engines, SAE40W, not 15W/40.You post this almost every time some one post a DD quiz so exactly how many engines have you seen that were defiantly "murdered" by using 15W-40 oil?

You are going to get differing opinions on oil type. I know early in the Detroit years the recommendation was a straight 30/40 weight. All I know is in the last 20+ years I have always used Shell Rotella T 15W40 in all the Detroits I have rebuilt or maintained and have never had an oil related issue. Take that for what its worthThanks for that memo, I personally did not know that and I would have dumped in 15w40
In the early 80s DD gave blessing to 15W-40.You are going to get differing opinions on oil type. I know early in the Detroit years the recommendation was a straight 30/40 weight.
