Are you talking about the spring and washer inside the filter? This is a bypass valve. What brand of oil filter are you using?
Thanks. Let me know and I will see if I can help you out.
I am going to hand you over to another expert. Some one will be with you shortly.
That is the anti drainback valve...The oil filter adapter is bad.
The only way this thing would blow out is if there were a serious restriction in the lubrication system, like a clogged oil filter...
This valve keeps oil in the top of the engine while it is not running, so it doesn't run the engine with the top end 'out of oil', until the pump gets it up there.
You have to change the oil filter adapter to fix it.
You have not actualy paid anything until you click Accept, either...
