Yeah, actually, there is.

It's called ARP's and a torque wrench.

yea, plus toyota undertorques their heads causing premature blowing.. clean job.
and where is the ECT located? is it on the block or by the thermostat housing?

IHateHacks · 05-17-2007, 02:13 PM

ECT is threaded into the water outlet housing. It is the sensor in the middle with a green 2 wire connector.

I just installed a stainless braided clutch line today, and I decided to change my spark plugs and run a compression test also today.

Has around 1500 miles on the head gasket, and I changed the plugs when I did the HG.

Here's the compression #'s from my first compression test on 4/16/06, a year before I changed the HG.

Cyl 1: 184psi
Cyl 2: 185psi
Cyl 3: 181psi
Cyl 4: 173psi
Cyl 5: 173psi
Cyl 6: 183psi

Now today the numbers were this-

Cyl 1: 185psi
Cyl 2: 185psi
Cyl 3: 182psi
Cyl 4: 181psi
Cyl 5: 180psi
Cyl 6: 183psi

I used a MAC digital compression tester, all of the spark plugs were removed, engine was hot, EFI fuse was pulled, throttle was held wide open, and I only cranked the motor for about 4 seconds on each cylinder. This is on a 20 year old motor with 123K original miles on it. Not too shabby if you ask me. I was pleased with the results.

And my exhaust is alot louder with new plugs, a definite notice in throttle response and sound. The NGK's that were in it only had about 1500 miles on them.

And I forgot to add that my Cyl 6 plug's white insulator that is exposed to combustion was rusty colored whenever I took the plugs out BEFORE my head gasket. 1-5 were always in perfect condition. You can tell alot about how the engine is running by inspecting the spark plugs. The rusty color was from water getting in the cylinder. Now yesterday was the first day I had the new plugs out after the HG swap. I pulled #6......and it was clean. Looked just like the other 5. I was satisfied after I saw that. I could post pics if anyone wants to see the old #6 vs. the new #6. And I don't by all means baby this car around. Maybe until the oil temp get around 190 degrees, but after that its fair game and I do drive it hard.

Just another update. My super monitor is reading 17.6mpg. And thats mostly around town driving, only had it on the highway a couple times for like 30 miles or so. The last thing it read was 18.7mpg before the head gasket. And it would go up when ever I was in boost, it was weird. Now it goes down when I boost the shit out of it and comes back up to 17.6.

88Tsupra · 06-25-2007, 05:58 AM

can you post the pictures for me plz. my last spark plugs was ngk that the original owner had and it was compeltely black around the the tip and the tip was the rusty color and now my new plugs look the same mostly on number 5 & 6 and i just replace it with NGK ones too with NGK wires

88Tsupra · 06-29-2007, 07:23 AM

hey did u get the pictures and oh how does your blitz exhuast sounds im thinking of going with that or the hks one or the apexi GT series i know the Apexi doesnt fit but ill make it

IHateHacks · 06-30-2007, 01:24 PM

Well I have pictures but my hosting site is fucked up so I can't post pics at the moment.

Listen, if the white insulator on the combustion side of the spark plug, near the electrode, is a brown color, then that is bad. All of the plugs must look the same, nice and bright white. Trust me, you can tell the difference if one is burning water.

I just did a block test on my engine yesterday. Passed with flying colors. I took a pic of the test fluid when I was done but cant post it right now. One thing I did notice is you have to take the overflow hose off the radiator and plug the nipple up with your finger to get an accurate test. Because you will draw air from the overflow tank, or coolant if its not empty, and the fresh air coming from the overflow will give you a false reading. You will think its good to go, but you didn't test it right if you left the overflow hose on the radiator and didnt' plug the hole up. And you should run the test for a solid minute.

And my exhaust is quite loud. But thats because I have no cat or pre cat and I replaced my O2 housing with a 3" downpipe. I have a turbo back 3".
