You're joking, RIGHT?

Look at my sig... Now that's scary!

 

ROFL!

Where did these #'s come from? Did you do the test?

I always wondered about the "compression test" these motor places perform. If a cylinder came up low what does the shop do? Eat the cost or just claim it's within normal limits, sell it and then blame the operator for the motors failure?

 

helpful rob lol

as a general rule of thumb, as long as there isnt more than 15psi difference between the cylinders, you are ok. 215-205 sounds pretty good to me especially if its stock with 60K miles. I wouldnt be worried about those numbers as much as how this place actually GOT those numbers. I dont know if you can check compression on a motor that isnt in the car.

 

do a leak down test. its just as easy as a compression test. if theres any leaks it will tell you where they are.

we just did a compression/leak down on my brothers Honda Challenge H1 test engine, its a bone stock 80k old 96spec Type R engine

Compression numbers = 235, 238, 235, 235 (throttle plate wide open)
Leak Down = 0-2%, 0-2%, 0-2%, 0-2%

its perfect.

 

My compression was perfect, my leakdown test proved cylinder 1 and 2 were FUCKED.... massive oil burning.. so make sure u get a leakdown test aswell.

All you need to do is jump the starter. Compression test tells one half of the story, leakdown tells it all.

 

tim...get the leak down test. If its more than 5% than don't get it. 205 on the last is ok could be a number of things but u won't know til u do the leak down. Or u could tear the motor apart too lol.

u get ur account set up yet?
