you always make good DIYs spaz, too bad your engine doesnt seem to get a good reading man.

its ok! Warranty my friend :thumbsup:

Damn that sucks. Good DIY, bad luck. Hope it's nothing serious.

Out of curiousity....what do you have your plugs gapped at? I've been running the same plugs as in your pic, gapped at .020 running 12psi, & my cars stalls when I drive slow & push in the clutch (parking lots, mainly). I'm thinking I'm gapped wrong:dontknow:

are you running iridium plugs? Because I am an to my knowledge you really can't gap an iridium plug because of the tip. What plugs are you running? Have you taken them out lately and looked at them? They will tell you lots about how the engines running

 

[Type-Spaz]

But if they're gapped @ .028 out of the box, isn't that too large for only 12psi?

but it varies on spark plug type... and being iridium I was told you never gap them. Use them the way they are. :dontknow:

 

[Type-Spaz]

Awesome! When you mean crank the engine 3-5 time do you mean by just turning the key on and let the engine crank 3-5 times or just turn the key on for a second and just bump the engine and do that 3-5 times?

yes physically try to start the car. So turn it on and hold it for a second or two while it attempts to bump over.

 

[Type-Spaz]

its .44 right? the gap?

all depends on the plug and the application

 

[Type-Spaz]

regular ngk iridiums on a k24a2 w/ bolt ons

never stuck a gaping tool in an iridium plug.. so whatever the read out of the box lol

Actually I have some lying in the garage I will go check. Now that I lost my job and em unemployed again I have lots of time

I got this out of Helms

My question. Is it really necessary for the steps for 05-06 models?
Cylinder Head

Engine Compression Inspection
NOTE: On the 2005-2006 models: After this inspection,
you must reset the engine control module (ECM)/
powertrain control module (PCM), otherwise ECM/PCM
will continue to stop the injectors from functioning.
Select ECM/PCM reset using the Honda Diagnostic
System (HDS) (see page 11-4).
1. Warm up the engine to normal operating
temperature (cooling fan comes on).
2. Turn the ignition switch OFF.
3. 2002-2004 models: Remove the No. 17 (15 A) fuse
from the under-dash fuse/relay box.
2005-2006 models: Connect the HDS to the data link
connector (DLC) (see step 2 on page 11-3). Turn the
ignition switch ON (II), then select PGM-FI,
INSPECTION, then All INJECTORS OFF function on
the HDS.
4. Remove the four ignition coils (see page 4-26).
5. Remove the four spark plugs.
6. Attach the compression gauge to the spark plug
hole.
7. Open the throttle fully, then crank the engine with
the starter motor and measure the compression.
Compression Pressure:
Above 930 kPa (9.5 kgf/cm , 135 psi)
8. Measure the compression on the remaining
cylinders.
MaximumVariation:
Within 200 kPa (2.0 kgf/cm , 28 psi)
9. If the compression is not within specifications,
check the following items, then remeasure the
compression.
• Damaged or worn valves and seats
• Damaged cylinder head gasket
• Damaged or worn piston rings
• Damaged or worn piston and cylinder bore
10. Remove the compression gauge from the spark
plug hole.
11. Install the four spark plugs.
12. Install the four ignition coils (see page 4-26).
13. 2002-2004 models: Install the No. 17 (15 A) fuse
from the under-dash fuse/relay box.
2005-2006 models: Select ECM/PCM reset
(see page 11-4) to stop the ALL INJECTORS OFF
function on the HDS.

Spaz you should put the specs up in the first post for the people who dont read the tread.

I think you'd only need to reset the ECU if you pull the fuse like they are doing. I unplug the injector clips so it's still sending signal just not shooting gas.

are those (yellow square) the injectors clips....??

yessir they are

 

[Type-Spaz]

which fuse do i pull...i found this diy on 8th http://www.8thcivic.com/forums/engine/84476-diy-compression-test-lots-pics.html and the guy pull fuse number 11 and 19....do we pull the same fuse on rsx???...what fuse number is the fuel pump??....

as far as the fuse... just read the label on the fuse box. According to mine on the RSX its fuse number 17. But I don't pull the fuse, I just unclip the injectors.

 

[Type-Spaz]

u had a blown head gasket huh?

yeah I got the engine from a salvage yard. Thats why you always buy a warranty. They gave me another engine .:thumbsup:

 

[Type-Spaz]

you can see how healthy and strong your engine is or is not. You can see if piston rings are going bad and bent valves

 

[Type-Spaz]

Which part are you double checking? The Fuse or the Injector clip pulling?

 

[Type-Spaz]

My car is an 05-06... :dontknow: :laughing:

So yup it works 05-06

I've compression testing maybe 100 cars?! Done it the same way every time. Just pull the injector clips and I have never had any issues.


Unclipping the injectors is the easy way, but the easiest way isn't always look upon as the best way. Of course the dealership is going to cut the power to the pump since the point is to not spray fuel. Plus, pulling one fuse is easier than unplugging four injectors.

 

[Type-Spaz]

can you seriously get a brand new motor through warranty for wrong compression???

I did. And made money doing the swap :rotfl:

 

[Type-Spaz]

So what does it mean if you have low compression? Bad valves? And also when you do the wet test, how much oil should you add into the cylinder first before checking compression? Like a drop? And if the compression goes up means your rings are fine???

Mostly it tests for bad piston rings. First you want to do the dry test. If it comes back low stick a couple drops of oil in that cylinder for a wet test. If compression bumps up then you have a bad ring started. The oil will fall into the cavity of the leak and bump up compression... Bad sign. If compression stays the same and is low it could be a sign of a bad valve seal or bent valve

i did just the dry test today.. 160 170 170 160.. but my engine uses a lot of oil.. almost a quart in 1-2months.. btw spark plugs are all fine as well. what could be causing the oil consumption?

lots of vtec :vtec:

 

[Type-Spaz]

nope. never vtec.. maybe once every cpl weeks

jack the car up and start digging around with a flash light for an oil leak

 

[Type-Spaz]

Base with 60k on it, got it with 52k on it and changed the oil and changed the plugs, the plugs looked pretty burnt and had a bit of oil on them so I changed the valve cover gasket and the spark plug gaskets as suggested by you guys a few months ago.

Checked my plugs a week after putting them in, (2-3 months ago) and they looked dry and carbon fouled but I was told it was ok. Been getting shit gas mileage...17mpg with 50/50 city/highway, so my guess was an o2 sensor...

I decided to do a compression test just to make sure the motor was healthy because cyl 3 looked a little different from the rest when I checked the plugs. Test read 185psi in each cylinder, and the plugs looked REALLY dry carbon fouled...which means the car is running lean... Do you think its just an o2 sensor causing the car to not give the right amount of fuel and my gas mileage? From what I know the most important part of a compression test is uniformity and they were all spot on 185psi so idk ?

as far as compression test your headgasket and your piston rings are doing just fine. As far as shitty spark plugs if all the plugs look like crap one of the possibilities could definitely be O2 sensor.

 

[Type-Spaz]

wow that is sooo low... did you have the throttle at wide open when doing this test?!
