Ok so i know this has been covered over and over and over, but im still not 100% satisfied with what im finding...
Driving a 96 civic dx. D16y7 at 160kmiles 5sp
Running 5w-30 high mileage. In phx,Az
About 3 weeks ago i replaced my transmission with another used transmissions as my old one was slipping and grinding bad. Put a lightweight flywheel and stage 3 clutch( yes completly overkill but they sent me the wrong one and i plan on boost in the near future so oh well)
Everything was fine and dandy but last week my dumby oil preasure light went on. Checked oil level and it was fine. Bought a gauge from o'Reilly and hooked it into where the old oil pressure sensor was. It read 0. ****... figured it was probably the oil pump so this week i bought an oil pump. Did the ol' shimming and porting technique on it. At the same time i did my timing belt and water pump. My oil pickup tube seemed fine as i ran tons of carb cleaner through it and it flowed fine, noticed a pretty significant dent in the oil pan tho..
Put it all back together..Started the car and cold idle was about 25psi, once warmed up was at about 10psi, within specs so not terrible but expected it to be higher..
Now when i rev anything passed idle it doesn't climb like its supposed to. At 4krpm, its at about 15psi. Havent found any leaks of any sort on anything... whats going on?
Is the dented oil pan causing interference issues with the pickup?
Should i switch to 10w-40??
Are my bearings just shot?
Whats the next course of action i should take? Any help would be greatly appreciated!
Thanks everyone

 

Post pic of oil pan.

Definitely could be worn main bearings.

 

Thanks for the reply. Its pretty hard to capture the concave on a dark surface but i did my best...
if it is my bearings.. is this something ill need to pull the motor for and possibly take to a machine shop?


Used a breaker bar as somewhat of a straight edge
