If your rocker shaft was busted and the valves were not opening, alot of the unburned fuel in those cylinders will end up in the crankcase. the problem is that fuel dries things out and hinders lubrication, the crankshft and camshaft bearing and journals can become damaged. fix your rocker, put fresh oil in, then change it a second time after about an hour of running, use a quality oil additive like MOA or Lucas stabilizer in the second change. low oil pressure can indicate worn crank and cam bearings and or journals.

I own a 1968 Imperial 440 V8. The intake valve push rod of the #1 cylinder bent and was causing knocking noise. I replaced it and the motor ran fine. The #1 cylinder started missing. Again it was a bent...


bent push rods come from improper movement of the rocker and valve
This can be from an incorrect length push rod-- some v8 engines run different lengths for inlet and exhaust
from rocker arm jamming on the shaft or rocker ball
hydraulic cam follower pumping up and jamming the valve spring to a solid block
bent valve stem above the valve guide
valve spring Colette moved or misplaced incorrect rocker for that valve-- some engines run different length rockers for inlet and exhaust
what to do-- if this engine was running all right for some time then the rocker can be omitted. if the problem has been occurring since the cold weather the the oil may be too thick and not allowing the follower to leak down properly
check the follower or replace it , change to a lighter viscosity oil for the duration of the cold weather
unless you have had a recent head change or other mechanical work done the problem will be in those areas.

Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor. How did the fuel get into the cylinder in the first place? Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer sensor. If black smoke is present, check the engine oil as in the white smoke example to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Call your mechanic and advise him of what you have found. I hope this helps you determine what could be causing your engine smoke

How to adjust rocker shaft on discovery td5


There are adjustment screws on the rockets according to RAVE.
The procedure is as follows:
1) Rotate the engine clockwise until No 1 injector lobe is at full lift.
2) Rotate rocker adjusting screw clockwise until the injector plunger is felt to bottom out.
3) Rotate rocket adjusting screw anti-clockwise one complete turn to give plunger the required bump clearance and tighten rocker arm adjusting screw locknut to 16Nm. Ensure the screw does not turn as the locknut is tightened.
4) Carry out the procedure for the remaining 4 rocker arms.
5) After completion of rocker arm adjustment slowly rotate engine clockwise 2 complete turns by hand to ensure that no injectors are bottoming out on their plungers.
