Marty's Z22SE Rebuild
- Thread starter Marty64
- Start date
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)

Starting the third rebuild !!!
I found a good German offer of a redone engine block painted in black.
86.5mm rebored and balancing shafts removed.
The crankshaft was controlled and polishing the crank pins.
With the advice of Gil-lig I measuring clearance gap between the crankshaft and the bearings of rods:
Gap is within the constructor tolerances so I can continue.
I think, on previous build I had reversed the direction of connecting rods and also dispatch them not in order with their conrods.
As Vocky said to me : surely the main cause of my blocked engines.

After that, i tried a start of the engine without fire it to see if oil pressure is growing.
Hummm, few seconds at 0.2 bar and after 0 bar.
Pffff i though another problem camed.
Control all pipes and wire connexions : all good.
Loking under car : oh noooooooooo : 3 liters of oil are on floor. WTF ?
After inspecting, oil flow by gearbox housing.
Only 2 possibilities : a crank seal failure or a leaking oil gallery.
