Top end power loss !!!

The list in my first post are the only things I have done to the engine. No other mods

spark plugs were the normal brownish color and they were not wet at all. i dont think car was running rich. if it was running rich they wouldve had black deposits. we found a leak in the fuel delivery line that was making everything smell like gas, hopefully it will be fixed and stop the smell. exhaust had the raw gas odor at start up, but afterward it smelled like it was burning fuel pretty good.

Did warm compression test, it had 175 across the board which i think is a little low, but not too bad. Engine has excessive crank case back pressure - it pops the dipstick on the first 5k rev. PCV valve worked fine, it actually sealed.

Engine is still having loud lifter noise. IDK if Alex primed them before installation.

Yeah, its making pretty expensive sounds

I have to say MAP sensor.

Get that thing off the intake manifold and give it a good cleaning with some carb cleaner and a toothpick. If you have to borrow Matt's just for the try then do it. i bet it picked up some shit while sitting in the shed all that time
