Thank you for another awesome video. I want to test my compression on my 1999 4Runner's 3rz and was wondering what kind of compression tester you have.
I believe this is the kit I have, but I don't have it with me right now so I can't check to be sure: amzn.to/2eouyJH Hope that helps, and thanks for watching!
That motor is not even broke in. Mine has 430 000km. Needed to remove the head because someone fitted the wrong plugs and 2 broke off when I tried to remove them. The cylinder walls still had cross hatches and no ridge on top of sleeves. These motors last when you do regular oil and filter changes. Cheerz
Hello . I am rebuilding my 2001 toyota tacoma 3rz engine. Do you know the compression for the 3rz-fe? In stock mode. Do you think my engine will last a long time getting it rebuilt? And is it a good idea to get turbo? Or will that cause engine to brake again or engine problems?.
I believe the stock compression ratio of the 3RZ is 9.5:1. If you want to turbocharge your truck, you can run 5-7 psi on the stock motor, but if you want any more than that, you will have to build the engine with forged pistons and rods, as well as upgraded valves, valve springs, and preferably cams. If you rebuild the engine properly, it will last a very long time, and the turbo should not harm that if you know what you are doing. Thanks for watching!
Just checked compression on my 3RZ-FE. To me his compression was a little low. New this engine should be at 180-to 200 psi. Right? Not saying his was bad but my test was kind of different with last two cylinders being lower. My was 205,205, 200, 198. Now here is the thing my engine is not near new or has it ever been rebuilt. My truck has 208,000 miles on it. So I am wondering is the compression to high maybe carbon build up causing it to be that high? Just wondering if others have got readings like mine with a high mileage engine. My truck runs smooth oil only turns brown in 5000 mile oil change. Sent oil to Blackstone labs and the said oil was still at half life at 5000 miles and I could up my oil change to 7500 with no issues. I doubt I will but good to see oil is holding up so good. Using Shell 5W 40 diesel truck oil because it has more zinc, than other passenger car oils. Plus this engine uses tapplets valves so that is a lot of friction. I wish there were more videos on compression test with the 3RZ-FE. Please post more compression test so that I can see if my test is wrong or if there is starting to be a carbon issue making compression higher at this point.
The reason my compression showed low was because I left the spark plugs in the cylinders that weren't being tested - I re-tested at a later date and found the results to be within the Toyota specs. Your compression seems high, but that may be due to an inaccurate gauge as opposed to carbon buildup. If your engine is running properly and oil analysis shows no issues, I would not worry one bit about it unless you have other symptoms of issues, like very audible valvetrain noise. Hope that helps, and thanks for watching!
@@redonKiLaus Do you have or know where I can find the Toyota specs ? I recently got my 3ZR rebuilt and all the guy did was rebuilt the head. So I am gathering info to confront this dude who ripped me off. I found carbon on all 4 pistons, was to have new ones installed on a rebuilt. Not good. Any info would be most appreciated!

swigga4O You shouldn't have to worry about that, just pull all of the spark plugs and the wires (unlike what we did in the video) and pull the EFI relay or fuse, and you should be good to go. Thanks for watching!
Minimum psi per cylinder is 127. The reason your numbers are lower than 127 is because you literally did this test wrong. Ten years ago. Next time you need to study up on how to do the test correctly.

Perfect just what I needed to know. Thank You for your time and video.
Thanks for sharing this information,

Thanks, I just ordered one for myself.

That vehicle looks like never been outside. Ever
It has about 185k miles on it, so it's outside quite a bit (though has been garaged when not being driven for its entire life). Thanks for watching!

Also should disable the ignition circuit so nothing gets damaged.

So you want to have all the plugs out when doing this?
@@shckltnebay yes, plugs out, engine warm, battery fully charge ,

@@rickrivers2909 I'd consult the field service manual...that's the only place I can think of with those specs. Thanks for watching!

Pienso El Gato esta muerte. Vaya con Dios, Toyota.
in addition to the relay, should I disconnect the main boot for the EFI also? how about releasing pressure from the injectors

You have to take all the plugs out before doing the test. Not one atba time.
