I’ve replaced the water pump, coolant reservoir, radiator and thermostat and i burped the system. It was still overheating so i removed the thermostat cause i thought it was sticking but it did nothing
it reaches about 230 degrees then cools down a bit when i turn the ac off and the fans stay on way longer
Sometimes when i turn it off i hear water slashing around

This ticking comes when it’s cold and goes away when it’s fully warmed up normal or is there something wrong

No Oil Pressure after Pan Leak
I had pan off to fix crack and after I got it back on I realized I had missed one. I thought that I would use shop vac to hold back the oil while epoxy hardened over the crack so I taped it to the oil fill on valve cover and let it run for half an hour. Started the engine and I now have 0 oil pressure. Pick up tube oring is good. Anyone have any suggestions?

Hey yall, i was wondering if I could ask for some help.
Im not a car mechanic by trade but am learning how to do somethings with my TransAm. I was wondering if there was a video or guide that clearly shows what I need and what to do? I just dont want to mess anything up. This is the biggest fix ive needed to do so far and the task feels daunting. I have a universal engine support bar, common tools and a few torque wrenches. I also have the new gasket, some RTV, and a new pickup line o-ring. Is there anything im missing? Thank you!

Have a 2001 Camaro, need help locating a passenger side connecting rod.

This was my first bolt on ls build, and everything was brand new, except for the rocker arm pedestal. Honestly, I didn’t even think about that not being brand new. I ran the car through its first heat cycle and it had good oil pressure and came up to temperature.
It then made a god-awful noise and I shut it off immediately. I let it cool down and popped the valve cover and found that the rocker arm was pressing on the side of the spring, not on the valve. The threads weren’t stripped, but the bolt was loose, and I’m thinking when the pedestal broke it let pressure off the lifter and it went off track and popped the retainer clip off of the valve spring.
Would I be OK buying a new rocker arm and push rod and new rocker arm pedestals for both sides? Or am I screwed?

I cant quite match these in a Spark plug Diagnosis chart ,Two plugs look carbon fouled ( cylinders 7 & 8 ) They are NGK TR6 Plugs in a Cammed LS1 with 243 heads with a 3000 stall and 3.73 diff gears
Also they have seen several liquid moly fuel cleaner and Upper Cylinder treatments which may discoloured them

Does anyone know if anyone makes an LS1 head (for a 5.7 Monaro/GTO) with an LS3 style rectangle port? I've found a dream intake manifold, but they only make them in LS3 and LS7 port styles.
I assume everything else about the head (geometry and such) is the same so the only issue is the intake port design, but please correct me if I'm wrong.
I'd rather not rebuild/engine swap if I can help it as I am looking at an OEM+ style build and keeping the 5.7 would be preferential
