I have a question regarding my recent compression test on my 1998 4 runner 2.7 litre.
Is this considered good? What is considered Factory Compression?

CYLINDER 1-210, CYLINDER 2-210, CYLINDER 3-200, CYLINDER 4-200 PSI

 

They are all with in 5% of each other so that is good. Just look up what they are supposed to have a did you close then you good to go. Most important this is all cylinders should be close to the same.

 

Thanks. Where would i look to see factory compression specs? I'm having a hard time finding that on info!

 

Take a look at the 1st link in my sig below. You may find something useful.

 

HMM THANKYOU!

So from what i read my 1998 4runner with normal compression pressure would be at 178psi and minimum should be 128psi. So what exactly does this mean?

CYLINDER 1-210, CYLINDER 2-210, CYLINDER 3-200, CYLINDER 4-200 PSI

I had a shop do it but should have got a proper explanation. on a scale of 1-10 what would you rate this lol? I just wanna know if its a strong engine im thinking of investing in a lift kit and new tires. Don't wanna build it up unless its a solid rig.

Also right now it is completely stock. I am only getting 14mpg which seems low for an auto 2.7.. Is there anything i can do to improve this? Already i've had a tune up done. Cleaned throttle, cleaned idle control valve and put a seafoam additive in with a fuel tank of 91.
Thanks guyS!
