Investigated on low oil pressure cause, i found another mistake :
In my oil pump, i saw that the spring is smaller compare to a Z22SE one.
What is the standard Z22se spring size ?
Does a smaller spring could have caused low oil pressure and damaged conrods bearings ?
Mine (3.15"):
The little spring was in my oil pump rebuilt engine and have part number 16804230 (not a gm)
I saw that on my VX220 engine the part number is GM 24450057
Also, can you give me the correct length that the oil filter housing spring must have ? Mine is 34.6mm (1.34 inchs)
