I did compression test on my evo today, need some inputs about its health. I bought it 4 months ago with high mileage 195K miles. I thought I did compression test first before thinking about rebuilding it. Here is the reading see what you guys think if I should rebuild or keep running it. Thank you.

Dry: Cylinder #1: 170, #2: 195, #3: 195, #4: 180
Wet: #1: 185, #2: 200. #3: 205, #4: 190

 

no one has any ideas?

 

Not that big of a difference between em, run it for a bit and start putting money aside for a rebuild I guess.

 

Those numbers are great for 195k miles

 

Numbers look good. I wouldn't change anything unless your planning to run big power and then I would have it rebuilt but not because of the numbers but because it's got 195k miles.

 

Yea, the numbers I think they are looking good but because of the the high mileage I don't know if I should do the rebuild or just wait until it is completely worn.

 

Wow those compression numbers are pretty spot on. Especially with 195k miles. that is amazing!! Has the car been stock its entire life? I would not be worrying about a rebuild.

 

Yea, those numbers on awesome. Nothing to worry about there.

 

i like to go by the rule of 'if its not broke dont fix it'
i'd hold off and save until it lets go.

 

Yup, I will run with it for now, however, my clutch just went out guess what it was still using the stock OEM clutch. This car was pretty much never been modified just like the previous owner said. Therefore, I will change out all the important seals and timing belt just a peace of mind. Thank you guys.
