How do I fix the tapping sound from the engine when i accelerate after it has reached running temperature


Adjust the valve tappets (yes, they 'tap') AKA Rockers or find out why the hydraulic self adjusting tappets don't work?

They transfer the downward motion of the cams on the camshaft to depress the valves. There is a thin clearance of about 8 thousandths of an inch with the engine cold. As the engine heats the clearance reduces. Over tightening causes the valve edges to burn, too much clearance causes tapping.

Manual tappets get quieter usually as the engine heats. Hydraulic tappets gets worse as the engine heats as the oil thins.

I have a Hatz1B20 diesel engine and it starts easily cold but will not start when hot?


check the tappet clearance when hot should be .012" inlet and
.14" exhaust
if the engine has a lot of hours on it , it may need a pump rebuild or the injectors rebuilt but I suspect a valve problem from the tappet clearance being to tight cold

Valve Clearance Valve clearance is there to allow the valves to cool in between combustion events (spark), and to make sure the valve closes properly and contains the combustion explosion. You need to cool the valves a little bit, the exhaust valve moreso than the inlet, as it's what sees the most heat as spent burnt gases go past it into the exhaust port. Run too little clearance and you'll cause the valve to "weld" a little bit to its' seat every time it closes, and then take seat metal off again when it opens. Do this enough times and you burn out the valve seat and need the head reconditioned. However, by running less clearance, the valve stays open for that little but longer, and you get more air in and out of the motor, and make more power. Run too much clearance and your motor just sounds like a diesel and loses power and tappet rattle annoys you while you're driving, so it's better to err on the side of caution.
The stock valve clearance (0.008" inlet / 0.012" exhaust, warm) is pretty good for any of the cams I've listed above, they're well-sized street cams, not really wild top heavy race cams that require super high compression to work, so don't be afraid to close the valves up a bit from the suggestions of the cam grinder, which will usually say between 0.010" and 0.014". There are a few ways to set your valve clearances:
Yellow Book Method This is from the factory 3K/4K/5K engine manual, aka The Yellow Books. It's the quick and lazy method.
Set engine to #1 TDC. Crank pulley timing mark should be on 0, distributor rotor should be pointing towards spark plug 1 or 2. Set tappets (counting from the front) 1, 2, 3 and 5. Rotate engine 360 degrees, crank pulley to 0 again, distributor rotor turned 180 degrees. Set tappets 4, 6, 7 and 8.
Nine Method I've never really gotten into doing this, takes too much time and maths for my liking :P Rotate the engine through its' range of movement, as one valve is "on the rock" of its' max lift, subtract the valve number from 9 and that's the tappet you should be setting. For example, if #8 valve is open, set clearance on valve #1. If valve #7 is open, set clearance on #2. And so on.
Stewart uses this method, and rotates the camshaft through its entire base circle and sets the clearance at the highest point. Which is a pretty good idea, as it compensates for the possibility that the base circle has been ground unevenly, and allows you to run the proper valve clearance that you want to run, instead of something that may be a few thou larger in reality.

How to measure tappet clearance with dial gauge


When setting tappets, it has to be born inind that the valve stem wears an indentation into the face of the rocker. This prevents a really accurate tappet adjustment, so the customer is right again. If you do not posess a tappet setting dial gauge, a normal engineers dial gauge will do just as well. The procedure is the same as using your feeler gauge except that you set the dial gauge up on the cylinder head with the pointer resting on the head of the rocker. Press down fairly firmly on the rocker valve end and zero the gauge. Next lift up on the rocker and read off the clearance, from the gauge, Use a magnetic base to support your gauge and repeat the pocedure for each valve pair.
