does anyone know of any? what would be a cause of the gear breaking. i put a b16 in my car and had it for 3 days. i filled oil a little over line and put a teaspoon of oil down each of the cylinders before i fired off the engine. could too much oil blow a seal around the pump causing it to lose pressure or something? i guess will find out soon. i will be taking the head off for ls vtec and i will disassemble block for ***** and giggles.

 

if it blew a seal,its most likely from too much blow-by.Thats from bad piston rings.

 

we broke 2 oilpump because we where using aftermarket crank pully without damper..

stick with oem... like Race jdm civic type r crank pully

Still,its RACE pulley,it doesnt have the rubber damper like the other oem ones have.

 

balance the rotating assembly.

i had an oil pump blow apart before as well, i was using an unorthadox crank pulley, lets just say that will be the last time i ever use that pos.

 

pls post pics of damages..

 

From what I've read, even full on race cars rarely have honda oil pumps
go bad. They are designed very simply. Only 2 concentric rotors with a
cavity in the middle and a blow off valve with a spring. Not many moving parts at all. Nothing to really break.
What exactly broke on your oil pump?

 

im thinking maybe the gear shattered. ive heard of that happening. but not commonly happening. oh well. ill find out soon.

 

well...on my street car, the stock pump gear shatterd. spinning it to 8500.
