Low overall pressure ( below factory spec) is usually a plainly worn out engine, however a low cylinder or two can point to valve issues, cam issues, head gasket leakage etc. .Do any of you guys know the compression ratio of the V8 tundra, 4.7 liter? Thanks . There is no engine code for low compression on a cylinder. If it is indeed low in that cylinder confirmed by a normal compression check it either valves, rings, head, or gasket. .

Do any of you guys know the compression ratio of the V8 tundra, 4.7 liter? Thanks Tundraholic I've never done compression tests that in-depth. All I've ever done (and with great success) is: 1) Disconnect spark plug wires. 2) Remove spark plug to test compression. 3) . If the intake valve is leaking badly, it'll cause dramatic (maybe 3 to 7 in) pulses in intake manifold vacuum on compression and exhaust strokes. Exhaust would flutter but not .
Checked o2 sensors for bank 2, they are both original toyota/denso. -Did compression test, getting low numbers on bank 2 cylinders, about 80-90psi across the board. . Keep in mind that there is nothing precision about the normal compression test on an engine. To a first approximation, the pressure should be equal to the (compression ratio . I performed a compression test today. I failed to read the portion of the instructions that say to pour a small amount of oil down any tube where the psi number is too low. . The test puts pressure in the cylinder and sees if the pressure leaks out though the Throttle Body, the Oil Filler Cap, or the Exhaust Tail Pipe. Before you start the test, you want to remove everything up to the TB, the oil .
From Toyota's press site: . Since the earliest and latest model year lists the same compression ratio,I'm doubtful there was a change in the 2001 models. Former moderator,circa 2001 2000 Imperial Jade Mica Tundra SR5 V8 4WD, original owner. Save Share

I would agree the more likely cause of compression loss would be the rocker arms falling off, very common especially in cold weather.

Let's take a look at what your test results mean: CASE 1: If you got a reading of 100 PSI or less (less being 0 PSI) on all of the cylinders you tested, then you've got serious engine mechanical problems. If the engine, on your Jeep/Dodge SUV (or pickup) has 0 PSI compression on all cylinders, this usually means that . Check the condition of the piston rings, valves, and head gaskets with a compression test. The compression is a very important determination of engine condi. You can determine the pressure fairly closely if you know the compression ratio. Standard atmospheric pressure at sea level is 14.7 PSI. Multiply that by the compression ratio to find the compressed pressure. So on a 9:1 compression ratio engine, you should see numbers close to 9 X 14.7 = 132.3.

Out through the gasket gap between the head and block. 5. Out through a crack or hole.. block, head or piston. A leakdown test can tell you where it is going. It sounds like the mechanic did that.

Toyota calls it the VSV For Pressure Switching Valve. This is one of the diagnostic steps in solving the check engine light trouble code P0446 "Evaporative Emission Control (EVAP) system vent control circuit malfunction". I removed the VSV to make it easier to test and take photos/video. This is from my 2004 Corolla LE. Tools needed:

True, this is a test that one can perform and compare the results to the coil's resistance spec. But as far as a "definitive" test ( as was asked for ), the coil must be actively tested and put under load to test for proper output. This type of test will detect leakage which is the most common failure of a coil. Important Tips And Suggestions. TIP 1: If your 2.0L or 2.4L Chrysler vehicle cranks and starts then it's best to do the compression test with a slightly warmed up engine. This is because as the engine warms up, all of it's metal moving parts (like piston rings, valves) expand with the heat the engine is creating.
