Yes, timing cover was cut to match block. I'll be looking for that crack when I take it apart.

Cracked block is what i think too. The hardest part is going to be finding a good block. Dare I ask how much Toyota is asking for them new? I don't think looking through the junk yard and spending time dissassembling used engines is the best idea. They could be cracked too and I'd be wasting...

it pours out of the oil pan drain plug. when i say pours I mean its a continuous stream when I put a few psi on the coolant system. Otherwise it drips with no pressure applied to the coolant system. I wish i could easily remove the oil pan and see exactly were it is coming from. Yeah, i wouldn't...

Okay...now I've got a new problem. I have coolant dripping out of my oil pan! I had this problem before...so I found the head was a little warped (but I now I don't think it was enough to cause this problem). At the time I assumed this was the cause of coolant getting in my oil. So I went...

Yeah the more i think about it, the more I think IJ is right. Rings just haven't sealed. I haven't had oil on the rings in 3 months. The last compression test was probably better because I had just come back from a drive were the oil squitters were coating the cylinder walls. Now the walls are...

wow. I guess my rings did go bad sitting. They only have 500 miles on them. JE pistons and JE moly rings, just bored over. They should have sealed by now. Any recommendations?

OK. I poured 2 cap fulls of oil into No.6. It went from 122 to 185!. Can I account for anything over 160 due to the oil displacing the air? So what does this mean that I am getting good compression now? Did my rings go bad sitting for 3 months? Or are they "unstuck" now? Thanks, Dennis

of course about the operating temperature for optimal compression numbers because of the ring gap but it is a small difference from a cold engine. What thread about the copper spray are you referring to? I didn't do anything different than IJ did his. The valve seals are outside of the...

I just installed a rebuilt head with headwork on my 7mgte and I'm getting some odd compression test numbers on a cold engine: 1. 95 2. 110 3. 118 4. 65 5. 90 6. 122 Now I know your thinking bhg but... 1. HKS stopper headgasket never even fired up, reused, inspected, viton throughly...

Nice NSX headlights. I did them too!

I wonder how many people entered. This is my first try. Good luck to everyone.

I didn't even know were this place is until I drove by yesterday on my way to Rage Tek. i don't see any towers!

I'm going to try to make it.

I'm in.

Fixed! Damn knock sensors messing up my dyno graph. 412hp/402tq

AH Thanks for the tip. I'll screw them in one at a time.

Question: Do knock sensors have to be grounded? I had code 52. I rewired both sensors with the coaxial cable. I still had code 52. I got a used knock sensor from a working car. I unplugged the front connector and plugged it into the "new" knock sensor. The sensor was just hanging out in...

Thanks guys! Sounds like you guys agree on the knock sensors could be the cause of this. Thanks for the info on code 51 (tps). I'll fix that too. P.S. yes, big turbo, fully built Dennis

Did bad knock sensors/wiring do this to my dyno reading? I street tuned the car, 17psi, 93oct, 11.7afr. It pulled very hard and very fast. The day before I went to the dyno I could feel the power drop. I didn't know what it was on the dyno. No codes on dyno. AFR fell to 10.6 during the power...
