SOURCE: 1992 nissan stanza my lifters

The lifters have nothing to do with the battery being changed. They are hydraulic lifters so there's no way to adjust them. Check your starter if the engine won't turn over.

Was driveing my f 1.50 with a 4.6 in it was find stop to get gas in it now the lifers are kicking

If it calls for mid-grade or premium gas and you put in regular and have been using regular it will cause a knock overtime. Also, you could be overdue for an oil change which has resulted in sticky lifters. Do an oil change and use Quaker State (as it has detergents to clean the lifters) and try some Sea Foam or Lucas in the oil as well. You will need to do a few frequent (100-200 km (approx 150 miles)) oil changes to clear the stuff that was causing the lifters to stick as it will end up in your oil filter and eventually get flushed back out if you don\'t.

Hydraulic valve adjustment

The lifters are not supposed to be adjusted.
Each lifter is a small "engine" itself.
They are supposed to be self-adjusting (this was changed way back in the 1950's).
If you are determined to adjust them, you will need to contact a place that builds race car engines, because there are procedures race cars use that adjust them.
Oh yes, you can also replace hydraulic lifters with solid lifters.
Some race cars do, and that is because, at really high RPM's, lifters can :"float", causing the engine to "top out" and not go any faster. I had that happen on a car back in the 1970's.
Be blessed.

Engine sounds like tek tek tek tek whenver it is running

Lifters & rockers in the head will wear over time and usually will require them to be adjusted. Thats really not that hard of a job if you are a Gear Head, and have a few basic tools. If not go spend some money with your local mechanic and have him adjust your lifters. As long as its more of a tick tick tick and not a knock, knock,knock. If its a knock, its in the lower part of the motor and its time for you to start looking for something else to drive. Good Luck!!

Theres a sound on the top head and it sounds like lifters. also it wont boost and the oil pressure is low, very low, can i get help with this please

Lifers will rattle if oil pressure is low. Have you screwed in an oil pressure guage to check. Should read about 20 psi at idle and 40-60psi above idle.
Causes are nemerous from low oil level to worn out engine. You dont mention mileage. Normally very good engines.

I have a 1993 ford explorer with a 4.0. have replaced head gaskets and find that the hyd lifters are pumping up to the point they are keepeing the valves open. have changed lifters and have the same...

You are not letting them bleed down.

The lifters will stay "pumped" for some time after the engine is first started. Sometimes its so bad the engine won't start (if fully pumped). If the engine won't start, you can cycle the engine by hand and compress the valve springs and let it sit for a time and they will bleed down (a couple at a time then turn 1/4 turn or so and wait again), but the easiest way is to run the engine at zero lash and tighten the rockers to spec. (one CYLINDER at a time) and let the other cylinders run until the miss goes away. When the miss goes away that cylinder will be at adjusted zero and you can move to the next cylinder. The thinner the oil the faster it will stabilize (which means engine hot).

If the engine will start at adjusted (but pumped up) lash, just let it run. It could take up to 30 minutes for the lifters to leak down.

Lastly, you can pull the lifters out, remove the snap rings, remove the plungers and drain the oil. Reassemble the engine with "dry" lifters, adjust them static (engine off) then start the engine. After the engine warms up they should fill with oil and run normally.

If you don't know how to do any of this, you probably shouldn't be in there to begin with. If you adjust them incorrectly you can damage your engine.

Some engines have no adjustment and those you just have to wait to stabilize. If they won't start, you turn them by hand and let them bleed down.

1986 chevette has alot of knocking coming from the engine.Lifters have been adjusted,but problem still persists, what else could it be?

Lifters tick. Rod bearings knock(typically the harder you mash the gas, the louder the knock). poor quality gas can do it if you need a tune-up.

Engine started tapping is it a valve gone

Hi, if the tapping is coming from the top half of the engine then the chances are it will be one of the hydraulic lifters that operates the valves the chances of a valve been gone is pretty slim if it was a valve your car would start to miss fire.

These lifters can be replaced and it is quite a big job to do. But getting it done sooner rather than later could save you alot of money just in case it does cause a valve to break this could cause you to have a seized engine and might need new engine.

The lifters themselves might be able to be adjusted but this would need to be done by trained mechanic as it takes exact measurements to find out the right lifter to adjust and thats if their is room inside the lifters to adjust them slightly. If not then you will need to have all the lifters replaced as to get the one out you need to be able to get to all of them. Its difficult to tell for sure witch one is playing up so this is why they replace them all.

On older cars you used to be able to adjust them with spanner and screwdriver but they stopped making them like that because they was un-reliable and was always noisy so instead of a spring type valve they use hydraulic ones now witch all cant be adjusted this would need to be checked.

Let me know how you get on or if you need further assistance ok
