oil filter blowing up on cold starts?????

Got a hammer?

hit the nail right on the head...
i took the filter and assembly off.

I could'nt have cut it off any better even with a can opener..
anyway this is what i found....
the spring and cap looked good, but the valve wouldent slide out...:wtf:
I bent 2 pic tools trying to push it out or even break it free. (nothing)

thank god i have a spare block laying around, i pulled that one cleaned it up put it on. refilled oil put on the new sending unit..

reluctantly i started it........

all was good...she didnt even smoke!

I really appreciate all the help..

I think i'll run it tommarrow till it reaches operating temp kill it then do another oil change.

since you have a few of them blown apart, i'd like to see what all of those filters look like internally. i would love to see the way they're made. just snap a decent pic of each filter element and bypass filter.

Little add on: (text I have)
Pressure Releif Valve
The oil pump can deliver oil at a high volume than the engine requires. To prevent excessive oil pressure, the system uses a pressure releif valve. The releif valve may be located in the block or part of the pump. The releif valve has a spring loaded ball or plunger located in an oil passage. When the oil pressure exceeds a present limit, it pushes the ball or plunger against the spring. This opens a releif port, allowing oil to return to the oil pan. A relief valve that is stuck open will cause low oil pressure. A releif valve that is stuck closed will cause high oil pressure. High oil pressure can cause oil leaks around engine gasket surfaces.

Wow that's a new one on me. I'll make sure to check mine while I have the engine out to make sure it's good to go. Great post lost!!!!

man there is a lot of shit in an engine that affects oil flow. i think i fucked my old engine by pipeing the pcv valve to the top one. then the big ends got louder and louder and the oil light started to come on when it was hot i was like what the face. anyways i dunno if it was the pcv valve or something else. i wont be trying that again

here YA go,I still have this,this is the same filter they are testing for the prelude site that we use on our cars. this will really open your eyes on filters,and them not being all they seem. and whatever you do don't use a freakin fram,or I'll have to :slap: you
http://www.ntpog.org/reviews/filters/old_filters.shtml

man that is one good info.
I always use STP, bosch or mobil 1 (when i can afford it).

are turbo cars supposed to run pcv valves? go to http://homemadeturbo.com/ and see what they say about pcv, because there is some certain way to run one

Cool my Rams and my Acura get Mobil-1 filters ONLY. I used a cheapo Fram filter on the 3G only because, well, it was a cheapo, old car lol. With the new engine going in eventually, it will also see Mobil-1 filters from now on.

Well, I will say one last thing in this thread. DON'T use Fram oil filters!!

that is wut i got last time when i changed my oil.:uh: i guess K&N for now on

Too much crankcase pressure would blow out the pan gasket,not the oil filter. The oil filter is connected to the oil main passages, not the crankcase.
good luck with the challenge.

Too much crankcase pressure would push the dipstick out of the tube, before anything else would happen.

Excessive crankcase pressure is generally caused from too much blow-by around the piston rings & will push oil up in the PCV valve.

...yes, what I meant was, the dipstick would come out of the tube before a pan gasket or oil filter burst. By the time the dipstick pops out, the PCV is ingesting huge amounts of oil.

True, I'll agree with you now.
