Only thing you can do is replace valves, try some lukus engine treatment first!

My 84 toyota truck engine 22r has a valve knock. when i start my truck i hear a loud knock coming from the head.do i need to adjust the valves?


check the valve adjust and see if one valve is lower/higher than the rest. The valves are hydraulically adjusted and if the knock is really loud watch for a slight miss at rpm's. The only thing that will give a loud noise is a loose valve seat insert. You may pick it up with a compression test.

Makes knocking noise that sound like something is loos banging only when jeep warms up and only in gear


TROUBLESHOOTING ENGINE NOISES
A KNOCKING SOUND IN THE ENGINE IS MOST LIKELY CAUSED BY ONE OF THE FOLLOWING
1. PISTON SLAP: Makes a sharp metallic noise. Idle engine and short out each cylinder plug. The noise will disappear when plug with bad piston is shorted. Noise will also disappear at acceleration. This can be caused by worn or out of round cylinder, or broken piston ring. Correct problem by re-boring cylinder and/or replacing piston.
2. VALVE NOISE: Makes clicking or rattle noise. Caused by excessive wear on valve stem or lifter, out of adjustment, or stuck valve. Correct by adjusting valve clearance, replace worn valve or lifter, regrind cam, replace valve guide and /or valve. A stuck valve can sometimes be loosened by passing oil through the carburetor while engine is running.

3. ROD BEARING KNOCK: Makes sharp metallic noise similar to a piston slap. Detection is opposite of piston slap. Rod knock is not heard at idle. Knock becomes louder as engine speed is increased. Caused by excessive rod bearing clearance. Correct by adjusting rod bearing clearance to .0015 inches by removing shims. May require re-pouring rod bearing.
4. REAR MAIN BEARING KNOCK: Makes dull knocking or thud noise. Detected at speeds between 20 and 50 MPH. Knock will normally decrease or disappear while pulling or decelerating. Noise will be detected the loudest at normal driving speed, when not pulling or decelerating. Correct by adjusting bearing clearance to .001 to .0015 inches. If knock is excessive, crank should be checked for out of roundness. May need to re-pour all main bearings to correct.
5. TIMING GEAR KNOCK: usually the most difficult to diagnose. If gear is loose or badly worn it will knock in all ranges. Run engine slightly above idle speed. Slowly open and close throttle. Knock will continue to be present, but just as engine slows down knock will become a slight rattle. Remove timing pin and reinsert into timing hole on timing gear cover. Press timing pin tightly against timing gear and accelerate slightly above idle. Knock will significantly be reduced or disappear. Correct by replacing both timing gear and crank gear as a matched set. The two gears should have a backlash clearance of .003 to .004. If more than .009 inch backlash, an oversize (.005) timing gear should be installed.
6. WRIST PIN SLAP: This can not be detected by shorting out the cylinder plugs. Rapidly accelerate and decelerate the engine speed. The engine will pass through a certain speed range when the wrist pin will rattle at about the same pitch as a valve tappet noise. This can be corrected by installing a new wrist pin bushing in the rod or new wrist pin f badly worn. Wrist pin should fit the piston and connecting rod with a tight metal to metal fit. The pin can be pushed into the piston and rod with a slight pressure of the hand. Pin to rod clearance is .0003 to .0005 inches.

Have 1999 nissan maxima code #po325 an code#po400 ?dont know what is wrong with car, check engine light on?need help please


Technical Description

Knock Sensor Circuit Malfunction
What does that mean?

A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. Knock sensors generally bolt into or thread into the engine block. This P0325 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0330.
FB.init("dd7d9e9681341cde77587bc6a2029f6f"); OBD-Codes.com on Facebook Symptoms

You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms.
Causes

A code P0325 most likely means one or more of the following has happened:

Possible Solutions
  • Check the resistance of the knock sensor (compare it to factory specs)
  • Check for broken/frayed wires leading to the sensor
  • Replace the knock sensor

P0400 - Exhaust Gas Recirculation Flow Malfunction OBD-II Trouble Code Technical Description

Exhaust Gas Recirculation Flow Malfunction
What does that mean?

The exhaust gas recirculation (EGR) valve is vacuum controlled valve that regulates the amount of exhaust gases that re-enter the cylinders. The powertrain control module (PCM) determines how much based on engine load, temp, and other conditions. If the PCM detects that the amount of exhaust gases entering the cylinder were insufficient or non-existent, this code is set.
FB.init("dd7d9e9681341cde77587bc6a2029f6f"); OBD-Codes.com on Facebook Symptoms

No symptoms will likely be noticed by the driver other than the MIL (malfunction indicator lamp). However, non visible symptoms will be increased combustion temperature and increased Nox emissions.
Causes

A code P0400 may mean that one or more of the following has happened:

  • Plugged EGR passage which restricts the flow of exhaust gasses
  • Faulty EGR solenoid
  • Faulty EGR solenoid wiring/harness
  • Vacuum lines damaged/disconnected to the EGR valve solenoid or to the EGR valve
  • Faulty EGR valve
Possible Solutions

Since EGR valve designs are different, no one test will suffice:

  • Using a scan tool, operate the EGR valve with the engine running. If the engine stumbles, the problem was likely intermittent wiring problem or intermittent blockage problem
  • If engine doesn't stumble, operate the EGR valve manually, if possible. If engine doesn't stumble and die, the ports are likely plugged. Removal of valve and cleaning of all ports will be required
  • Checking of solenoid can only usually be done with a scan tool, because most solenoids operate with a duty cycle of voltage, rather than constant voltage
  • Check all vacuum lines, hoses, etc for any damage
  • Visually inspect the solenoid harness and the solenoid for damage
  • Replace EGR valve

Lifters are knocking and there is a missing in


lifters tick and noise is upper end of engine if lifters are making noise could be from a bad valve,bad lifter ,push rod ,oil pressure,rocker arm - need to take do compression test find out if valve problem and which cylinder is problem also take off valve cover and check for proper oiling of valve head and look to see if and are damaged or loose-------a knocking sound usually comes from lower end of engine,rod knock etc.and thats usually rebuild of engine

Engine code 43 lights up engine has spark knock repaced esc module knock sensor tuned it up it runs rich and has the spark knock isssue


code 43 throttle position sensor out of adjustment.not working.if you replace knock sensor and it still spark knocking.make sure the wire connector is not broken.go to higher octane gas .make sure engine timing is correct. also make egr valve is opening when it suppose to it will cause detonation.you will need a scanner to check tps and egr valve.

I have a 1991 Olds custom cruser that pingsthe motor ping


Either your valves are knocking. Your IAC (Idle Air Control valve), or your knock sensor. The only thing is that if your knock sensor is bad it would throw a code. Your caddy could be the problem but again it would throw a code

APC Solenoid Valve Knocking


The APC valve regulates boost pressure (via the wastegate) to avoid over-pressurising the engine. It ensures that a safe boost pressure isn't exceeded. Don't run with it disconnected or you risk blowing the engine!

Problem areas can include: knock sensor on the engine block (also poor quality fuel, dirty engine causing knock); engine ECU.

You need to provide more information about when this happens:

hard accelerating? (likely poor quality fuel, dirty plugs/engine causing knock) and general driving similar.

idling? possibly a knock sensor or ECU related problem

What rpm? what boost gauge pressure?

as an outside chance, maybe a sticky wastegate
