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?

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.
