Mark II Grande cylinder head noise


Sounds like a bad rod bearing, no cure except a rebuild. I assume you do know the difference between spark knock and bearing knock.

V6 knocking noise


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.

Our 2005 Montana SV6 developed severe engnine knock, with dramatic loss of power, no prior problems that may have lead to this. Our mechanic thinks the oil pump was beginning to fail, and that maybe only...


Is the knock a thudding noise similar to someone pounding on a metal door or is it more of a rattling or chattering noise? If it is the thudding noise there is likely lower end engine damage. If is the chattering or rattling noise it may just be lack of oil to the upper end or head/s of the engine. How far have you driven it like this? If not very far it may have minimal damage that can be repaired by just installing a new oil pump, but if driven over a few miles like this it could be excessive and need new parts+repairs. The oil pump may not be easily changed but extra repairs are definitely going to cost more.

VW Golf engine rattle


You are experiencing detonation. Main causes are:

  • Low octane fuel - Use higher octane rating fuel.
  • Incorrect ignition timing - Readjust timing
  • Too high compression ratio(due to engine mods such as skimmed head or high compression pistons) - replace modified parts
  • Air/fuel mix too lean - Replace fuel filter and readjust.

Engine rattle noise


Have you checked your oil? Sounds like you may have run it way low, the loud metallic noise is probably metal on metal contact inside your engine, add oil and it that fixes it, count yourself lucky, if not need to take it to a shop.

4.3 vortec engine , engine noise, knocking or tapping on top of engine, not when cold , but starts noise when it heats up, and gets louder as it gets hotter and hotter!!! Sounds like noise is in the center...


The knocking or ticking is going to determine if it is in the top end, lifters, push-rod or rocker arm issue or the bottom end that would include pistons or bearings.
If it is a ticking noise, it will more than likely be a valve train issue.
If a knocking noise, piston or crankshaft related problem.

Attached is a web site that you can listen to a piston slap which is a known issue for your 4.3.
Listen to the noise and see if it sounds similar to your problem. A piston slap will generally sound as though it is coming from the central area of the engine.
Listen to the recording and let me know.

Lifters rattle when you first crank it up for about 5 mins until warm, Shouldi replace the lifteror wouldbe wasting my money to do so,.It runs great an use no oil 3800 -v-6 in a 2001 camaro, what...


Are you sure that the noise is a rattle? lifters make a ticking noise, pistons, piston pins and bearing rattle, lifter tick goes away in seconds, piston and bearing related noises take longer, and in the case of rod bearing not at all, it sounds like you may have piston noise, and in that case I would not worry about it, I would run a few cans of combustion chamber cleaner with you next 2 fill ups, carbon build up on the the # 1 piston ring land can cause the piston to "rock" in the cylinder and make a rattle type noise. I have a 1996 Corvette that has a rattle, it is a piston, GM checked it and told me not to worry about it, of course that advice cost $50.00. Also this type of noise is common to the later production 3.8L V6. Hope this sets your fears of a large repair bill to rest, just drive it, but make sure you use the correct oil and change it when recommended.
