Hi all,

I'm in the process of buying an engine for my S2k, since my original F22c finally took a dump.

I found a F22c for sale that is out of the CR, verified the VIN and everything seems legit so I'm about to make a purchase and have it shipped.

However one concern I have is that the Compression test readings the seller has sent me reads extremely high.
I've never seen such figures before (or maybe I just didn't search enough, who knows)

I'd like to gauge some ideas from here before making a final decision.


Again the motor is out of 08 CR, with 60k miles on the clock.
Compression test and leakdown test figures are as follows:

Compression test

#1 290
#2 291
#3 285
#4 290

Leakdown test

#1 0%
#2 1%
#3 3%
#4 1%


The seller claims that the testing was done when the engine was cold.

Should I be worried and sway away from this motor and find another one? or am I going to be fine with it?


Any inputs will be greatly apppreciated.

Thanks!

 

With compression tests the absolute values can vary with the gauge used and testing procedure. IMO The important thing is that the readings are very close between the 4 cylinders


What year is your car?
If its a 00-05, keep in mind that you will need to swap some parts from your original motor. Like crank sensor/trigger wheel, cam sensors/trigger wheels,valve cover, coilpacks, and your intake manifold including fuel rail/throttle body/etc.

 

Thanks.

Mine is 07, so I'm assuming it will be a direct swap, since my car already is a DBW.

So I should be worrying about whether each value are within close range rather than the value itself, correct?

 

Those figures, especially the leakdown results seem pretty exaggerated. I wonder if the test was done incorrectly.

 

To be very honest, I would pay for a shop that I as the buyer chose to do the compression and leak down test. If numbers are good then, make the purchase, if not swallow the $75 loss

 

My friend who is a mechanic also says the same thing, that's when I started thinking maybe there's something wrong with the motor.


The thing is, that I'm in CA and the motor for sale is in FL. I don't have any leads to the shop near
who I can trust to do the compression & leakdown test for me.

 

Where in FL?

 

Tampa area I guess.

This is the motor I'm talking about on this post right now.

 

If it helps, thats who I purchased my F22c from and still purchase things from. They are legit, I'm in St. Pete. Have them do another compression and leak down test as they offer it as one of their services. They also have a 30 day warranty, so once you receive it, have another compression/leakdown test done if you're still nervous.

Thanks for the input.

I did end up purchasing the motor.
