sweet i'll have to pick one up... and all i do it thread it into the spark plug hole and crank it over?

FrestyleFC3S

yea im pretty sure its blown...i had two guys around here listen and theyre pretty sure too...theyre rotorheads over at the evil forum but cool nonetheless ima try and get them in here



anyways looks like its time for :



rebuild kit....haltech....ito ports...720s .... any other suggestions....



im thinkin around 2500 for the full rebuild and everything....im gonna be doing it all myself with djgiantrobot and the guys up here in newark, DE....

What about the map sensor? Did the little hose come off? If you pull the plugs you should hear loud thumps as the motor turns over.

FrestyleFC3S

yea people said to check that...but im almost 100% positive that its dead

I always thought you were supposed to plug the tester into the leading hole since its larger...?



Also, you need to hold the throttle all the way open while youre cranking it over and doing a compression test.

Ok here are the steps to the compression test.



1) make sure you have a good battery

2) pull the EFI fuse

3) pull both leading or both trailing plugs or all of them ( but do not mix and match the plug holes you are getting the readings from, they must be out of the same holes, both leading or both trailing

4) install compression tester in first hole, there are two ways you can do this to get the correct reading. Most gauges have a peak hold button on the side, you can either hold this button, or remove the schrader valve in the bottom of the gauge hose

5) prop the throttle open or have it held to the floor so that there is no restriction for the air that you will be measuring.

6) crank the engine over and observe the gauge this is easier with a second person or a starter button, if you do not know what a starter button is or does find the second person to help

7) watch for the needle to jump as the engine is cranked over, make sure you get at least 6 revolutions of the motor

8) record the readings and move the compression testor to the next rotor and repeat step 6 and 7

you should have 3 distinct needle jumps reading in the 100's or higher

9) post your compression readings for everyone to see, you will know if there is a blown apex seal(s) from the reading





Hope this helps

make sure the engine is HOT when you do this

Your engine is blown. It sounds like it is doing the death shake to me. It looks like a paint mixer from home depot at idle right? No power. It sort of smooths out at higher RPM but there is still no power.



You can do a compression check to confirm this. From what you decribed to me it sounds like it is blown.

FrestyleFC3S

yeap....jims i think we all have this correct assumption



dj ur coming over this weekend though right?...we can do this with the one you have....and im gonna start to order the parts this weekend - next week



these guys here in newark down the road from me are gonna let me use their house and stuff to pul lthen engine and rebuild at....so we got a place to do it now....
