Thanks for the video. I have a question, this compression test should be performed when engine is cool or warmed up? specially in case of overhauled engines.
Hi Peter! One question. Am I supposed to disconnect the ignition system? On my anolog compression tester kit and says the ignition system needs to be disconnected and the throttle should be open. Should I take they advice of the instructions or is there no need to worry about the ignition system or throttle?
Great video. I did my first compression test today. I have 125 135 140 143 psi. The result of the test with oil is the same. What is the problem I can get your mind. Thanks!
@@PeterFinnTheCarDoctor My car is 2005 corolla vvti engine. This test is normal. The spark plug has a light oil leak in the bed. And I suspect the valve setting. Sounds like low values to me. I take your help
+Richard Yap Hi. Fuel supply stops so, that we unconnect the fuel line. Look my video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3hlcQd9Rwk8.html
+Peter Finn I do not understand after watching both videos. Do you mean removing the fuel pump to isolate the fuel line? That will be a big job isn't it?
You can either disconnect the fuse for the fuel pump or disconnect the fuel pump relay or disconnect fuel line and redirect it into a fuel can . All are easy to do.
Hello Peter If you are within the USA please place a link to where that Compression kit can be found for sale. It says KompressionTester, then I believe it is Eutopean perhaps German in manufacture. Thanks, Christian from New Haven-IN USA
@@PeterFinnTheCarDoctor I only asked because some people say is not necessary to removed them all and some people say has to .....me personally I remove them all Regards
I would like to buy Toyota Corolla fielder 2012 driven 98000 KM get the test result for the compression test Cylinder 1 147.9 PSI, 2 150.8 PSI, 3 117.4 PSI and 4 150.8 PSI. Is it ok to buy this car? Thanks in advance.
Hello. I tested on 4zz-fe vvti engine the compression and the result is: cylinder 1: 13bars; cylinder 2: 15 bars; cylinder 3: 15 bars, cylinder 4: 15 bars. The car has 170.000km and I have a misfire on cylider one no matter what I did (change coils, spark plugs, admission gasket etc). Is there a probleme on cylider 1 because of the compression being smaller than the other 3 cylinders ? I also did a wet compression on cylinder 1 (put some oil inside) and it was over the scale...(20 bars). It seems like the rings on cylinder 1 wear out a bit. I always used 0w30 oil. Thank you
@@PeterFinnTheCarDoctor It was the exhaust valve on cylinder1...didn't close enough. It was a 0.3 mm gap. I replace the bucket on cylinder one with proper dimmension (smaller)...everything is ok now.
