Compression Test

[Smooth_Imports]

Well i took the day off of work so i could figrue out what was going on with my car. Well i did a compression test and heres the results.

Cyl 1. 190
cyl 2. 70
Cyl 3. 180
Cyl 4. 195

So this means my rings are shot right? So now it's time to buy new pistons and rings right? Let me know what brand / model i should go with. I should buy rods while i'm at it.

Well, if you get aftermarket pistons...you're gonna need rods. You don't have to buy new pistons, just rings and bearings.

Thats the crazy thign, Why would cyl 1, 3 and 4 throw codes when 2 has the low compression.

ok.. now are you sure its the rings.. did you add a teaspoon of oil to that cylinder and see if it raised the compression... or a leakdown test to make sure it's the rings.

and since when does the ECU throw a code for individual cylinders??

YEah i added oil to the cyl and it jumped up to 150 from 70.
Didn't do a leak down test because a con't have compressed air here.

I don't know whn is started but thats what it's saying in my helms.

How do you do a compression test? I wouldn't mind doing that on my ride just to make sure its running alright..

I think it was his motor running super lean, causing the misfiring, and detonating...frying the rings.
