7.3 idi engine shudder/miss
I prefer delo 400 the point is rotella was a good oil but now its not so great and for towing and warmer climates run 15w-40 for cold climates 5w-40 and make sure is diesel oil because regular motor oil don't have the detergeant package to deal with the soot and acidity our engines produce via...- CBRF3

Quick Alternator Question 1988 7.3
My advice do a 10si / 12si GM 1 wire self exciting alternator swap I prefer the 12si myself rebuilds you can do yourself for like $30 and these things are tanks and simple and allows you to cleanup the wiring on the passenger side of motor and remove the external voltage regulator...- CBRF3

Top speed 55mph normal for 6.9?

Top speed 55mph normal for 6.9?
You have a point but from experience a C6 slippage issue is often noticeable you slow down but RPM's stay the same vs other transmissions the RPM's would drop if it was slowing down its a simple test the poster can test. I forgot to mention this as have not dealt with a C6 in forever I always...- CBRF3

I bet money it was 180 out this is known to cause the smoking and very odd running and causes them to catastrophically grenade due to cylinder washing aka raw fuel going into oil and making the oil more diesel than oil and a inner rod becomes a outer rod and leaves a nice hole in your block and...- CBRF3
