Just fired up the new 469 pump gas motor in my Pro Street, and to my dismay almost lost it because of a bad filter! It started good and I adjusted the idle at 2000 RPM and played with the throttle for cam break-in. I checked oil pressure and it was at 30 idling at 2000- 2200 and the temp. was good. I went back up front and played with the throttle while checking for any leaks. When I checked again the press. was down to 20psi. This time I climbed in and worked the throtle while watching the gage. As I increased RPM the oil press. decreased so I shut her down. Turns out to be a bad FRAM PF25 filter. I had just picked up some HP2 filters for the oil change so I changed the filter and the pressure was back. Thank God! 35psi at 2000 and 60 at around 4000! They're gonna get this one back! ... Eric

Anyone cut open a Napa silver filter?

the PN's match the Napa gold and wix lines.
going by a quick visual check they look the same.

GTO- to answer your question, I do not have anything done to my bypass. Also, the Fram HP2 has always been on the stock oil filter adapter.
I have a comment and a few suggestions.
1. Turning the oil pump with a screwdriver and getting oil out the hole for the adapter only proves that the shaft isn't broken, and that unrestricted oil can flow about 6 ".
2. You may have a serious oiling problem, and I wouldn't recommend starting this engine again, with anybodys filter until you prove a couple of things.
3.Put the oil filter adapter back on with any unpoluted filter. Use or borrow or make something to spin the oil pump through the distributor hole(as in priming ).
4. Have you done this before? The reason I ask, is that when you use the reverse on the drill, you can definately feel when oil pressure developes. Sometimes the drill will start to smoke (good oil pressure) If your drill spins effortlessly, you have some sort of internal problem.
5. Remove a valve cover and listen to the oil, you can hear it coming through.(do the pass side valve cover,as it's the last to get oil. You should see oil coming out the pushrods as it works it's way to the back. It may be necessary to turn the engine over by hand every once in a while to insure all the passages are getting feed.
6. Once you've proven that your oiling system is functioning, you can put on different filters to see if things change.
7. If all this is normal, and shows no problems, then procede with startup.
8. I have always been told not to break in the engine with synthetic products, and recommend using a quality 10w40 or thicker regular type oil until this is figured out.

One other question, Where is your guage hooked up?

Let me say I've never used a Fram filter that was a direct replacement for the PF24 AC filter (the Fram PH25) so I have no opinion on those.

I've always used the HP1 filter with a remote setup utilizing Nunzi's plate that mounts on the block in place of the factory oil filter housing. Been using the HP1 in a remote setup for more than 5 years and never had any problems.

I realize others have had problems with the OEM replacement filters, however, but it hasn't deterred me from using the HP1 filter. Look at it this way. If you were going into a particular diner for 5 years and loved the food, and one person told you they went in there and thought the food sucked because they got sick after eating it, would you stop going to that diner?

[Brian Baker]

Black Bear wrestling? I'll pass. Canadian beer sounds good though (I always did like Molson). Maybe at Norwhack?

[SupergasDil]

I know it's old news but I went from a PH8 to a HP2 and the pressure increased by 5 lbs

[Brian Baker]

Ditto to what Steve said. Sheesh! I've been going to the same diner for breakfast every Friday for 5 years, and the food is great, but because one person tells me they went there and got sick from eating the food, I should stop going?

Of these Fram failures, has anyone documented that it was an HP series filter that failed? No? I'll keep using the HP1 with confidence, thank you. Been using the HP1 for 5 years now without fail.

While syn. oil is not recommended on break in I can say syn. oil is far superior in every application except the diff. O.K. let me have it

Wrong,
use syn. oil in every app. even the diff and trany.

Amsoil in the diff.

Can you hear me now?

Bill, we're on the same wave length. I will be doing all of those things with the remote setup and the System 1 filter. My pressure is taken by the distributer. The reason that I asked about your oil filter bypass is that when you get a bad filter or you somehow plug your filter you would go into bypass and not notice anything. If I would not have had my bypass pluged I would not have noticed (IF it is my filter). I did prime the engine before startup and it seemd OK. I will prime again tomorrow.

Basketcase I had the same thing happen in 84' to a Dodge van, 318 engine. A couple of days after oil change the engine seized. The Dodge dealership found the Fram oil filter had disassembled. Fram bought the engine, so I have less problems with the company, I won't buy a filter from them though.

I think this
link was posted once before but it is extremely informative. This guy took the time to cut open a bunch of filters and compare them on his site.

Worth a look.

[Brian Baker]

Regarding these "strings" around the outside of the filter element, I think the issue with them being there is getting blown out of proportion. The oil enters the filter on the outside of the element and exits through the center. If anything, the element media would collapse in a failure, not "blow out". The "string" is probably there to hold the element in place (or in shape) while the end caps are being placed on it in manufacturing.

Had a System 1 filter. Its great, till it gets dirty, then you can't clean it........

Maybe I missed it but did anyone cut the HP2 open and compare to the WIX or NAPA filters?
What are the part numbers on those filters that are comparable in size, capacity and flow to the HP2?
I have run HP2's on my 9 sec injun, 2) 11 sec injuns and am running 1 on my new blower injun. About 13 years now with no injun failures.

Screen is easy, its the inner tube with the check ball inside that you can't get to that worries me. You can never tell if its clean inside or not.
