  1. DT414 out of 1972 1066 with 7500 hrs. CaseIH engine oil since I owned it @4500 hrs.

    Found a bad camshaft in my DT414, (bearings had slight wear but lobes were rounded off badly and tappets were pitted).  I was wondering if this was a problem with these engines?  What would cause the tappets to pit?

  2. This is a factory DT414, has never been opened up with app. 7500 hrs. Finally tore the engine down and the crankshaft/rod bearings looked very good, no cracked pistons, some slack between rings and ring grooves, wrist pins are tight, injectors tested good. Head is getting reworked in a machine shop, (oily residue in the intake manifold, none in the turbo) no word yet on the overall condition. The lifters were pitted and the cam lobes are worn bad compared to a new cam!!!
  3. The motor has never been opened up, no repairs have been made to it. I am trying to find out what is going on with this motor. Pulled the valve cover off and noticed oil wasn’t lubricating the rockers, thus trying to find out where it’s losing oil pressure
  4. Can anyone give me the route sequence of the motor oil passage? I have 60 psi at idle but do not have oil getting to the rocker arms. Verified with a 2nd analog gauge at the oil sending port on the block. Would the bearings be bad at the crank with this much oil pressure? Trying to troubleshoot the problem
  5. No oil pressure on the top end has to be a spun bearing

    1066 oil flow

    I will have to pull the oil pan and look there 1st, then go higher in the engine I suppose

    1066 oil flow

    The clacking noise has not been diagnosed, it will only clack at operating temp

    1066 oil flow

    Only thing replaced was a 170 degree thermostat to a 190 degree thermostat, that’s when it started the clacking noise. It never ran to the hott on the gauge. Temp gauge needle due south with ole thermostat, now southwest with new thermostat

    1066 oil flow

    No repair made to the engine, just started making a clacking noise when at operating temp. The 60 psi is cold engine at low idle verified with analog gauge. I did remove the valve cover to investigate possible valve misadjusted when I noticed the lack of oil at rocker shaft

    1066 oil flow

    I have 60 psi of oil pressure at low idle but little to any oil pressure at the rocker arms. Where could the problem lie?
  11. (1066) The oil pressure gauge senses oil pressure before or after the crankshaft ? So if a crankshaft bearing spun, I wouldn’t be able to tell by the oil pressure gauge?
  12. I agree, Help this guy out!!! ?
  13. How would I check this valve insert for movement?
  14. I hope it isn’t a wrist pin or piston! Why would it not do it all the time? How would I check it besides tearing it apart? Honestly I know what that injection pump chatter sounds like, had a 1566 that would do it on startup and that chatter is a rapid chatter
