Do a compression test cold.
Then do it hot.
Do it with the throttle closed too, as well as open.

Then you'll know it makes no difference. You'll learn quick.
Don't put oil in.
Look down the plug hole and see if there's oil on top of the piston.

Wtf are you talking about?

OP: this guy is trolling. Take a look at his other posts. Yay internetz.

Flat our wrong. You can look at the mark on the crank pulley, pop the valve cover, and the timing cover, and do it in the car.

These are DOHC motors... You know, dual over head cams... Only V motors do you really have to worry about possibly pulling the motor, and even then, most people take out the radiators and other accessories at or behind the bumper, lift the valves, and pull the cam right out the nose... But you'd know that if you were actually a Mechanic...

I ran the car hard 4 times and the. I ran it hard 7 times. Other than that it's only been babied.

There should be some way to ban people who are purposefully spreading bad information that will at best waste peoples time.

The manual clearly calls for performing the test with a warm engine with the TB fully open.

In another thread, he says a modded VIII DV will hold 80psi. His posts are strikingly similar to Jerry's "flat earth" thread. Coincidence they both pop up at the same time?

Children WILL be children.
If you've actually done compression tests yourself you'll KNOW that hot and cold, throttle open or closed, makes no difference to the numbers. It might take one or 2 extra revolutions to get there.
By disagreeing with me.......it means that you don't know (you've never done it yourself)
Likewise with the modified plastic BOV......you've got no idea.

If you don't know these things then how are you going to make an informed decision based on the results of the tests?

Everything is on youtube......like here.


here too.

Thanks for all of the info. I'm always up for learning new things.

Don't believe everything you see in a youtube video. Are you claiming you know better then the engineers that design and manufacture these engines? In the factory manual it sets the criteria of having a warm engine with the throttle wide open. I would make an argument but i don't have to. I'm not arguing with you, you are arguing with Mitsubishi about their engine.

That's me. Never done so much as a compression test on a car, before.
seriously, what's with all the trolls, lately? Not just this guy, but there's been others, too.

Update: I did a compression test with a warm engine and my personal compression tester gauge and my numbers are pretty good. Idk if u guys can see them clearly but they're about 150 psi on 1,2,4 and 155 on 3. So it's close enough for me.

As you can see, warm...cold....no difference.



Glad it tested better, this time.
