Did you change the cam and lifters or just the lifters? New lifters and an old cam may not spin properly. They are suppose to wear in together. Replacing one and not the other can make it worse than it was. Always replace them as a set. I'm not one for engine additives. You can try replacing a quart of Lucas Oil in place of one of the quarts of oil in your engine.

I have a ticking sound coming from the rear of the car in between the rear tries sounds like a clock ticking, what is it


An increasingly noisy ticking sound coming from your engine could indicate a lifter malfunction. I once had an exhaust valve lifter 'mushroom' where the cam makes contact with the flat tappet and the lifter wouldn't move up & down smoothly. This kept the exhaust valve from letting out the unspent fuel through the exhaust and the fuel had only one place to go: past the rings & into the oil. My cylinders needed rehoned.

It could be just a lifter gone bad. Unless you're into major HP(say over 400) you've probly got hydraulic lifters. This type builds up oil pressure to take up its 1/8" or so of slack they'll see when the engine hasn't recently run .

Ticking coming from right bank replaced the 2 i thought but still is ticking


You really did not explain at all. What was ticking? It could be injectors, valve lifters, etc.?

If it is fuel injectors, they are supposed to tick.
It is when they don't tick that you worry about them.

If it is valve lifters, then you need to try adjusting them. They may be hydraulic, but still could be beyond the range the oil can account for.

Let us know more, and we can explain more.

Valve ticking


There is no valve adjustment on a 2.0 engine they are equipped with hydraulic lifters. Try changing the oil and using marvel mystery oil it will usually clean up sticky lifters. If that doesnt clear it up in a few hundred miles you will have to replace the defective lifter

Ticking noise from engine


You might have a bad hydraulic valve lifter (assuming this engine has them)... you could try an aftermarket product designed to unstick valve lifters.... any auto parts store carries them.

My friend just got a 1988 ford ranger  v6 2.9L and has a valve tap and was wondering what different kind of ways he could fix this


if its an ohv type the most common fault is that the oil ways to the rocker shafts become blocked
so get some flushing oil drain the oil and replace with the flushing oil and run for the time stayed on the can then Change to good quality oil and new filter
then remove the rocker covers and check and adjust the valve clearances
if its an ohc type its all hydraulic adjustment
you could try flushing as above but apart from that the only other way is to change the lifters and followers
hope this helps
