ever seen the adds for the 20 dollar oil change that read "5 quarts Penzoil and a fram filter - 20$!" Engine killer combo. Wix, Napa (made by wix) or baldwin. Fram are not what they use to be. They were good once, but not any more
Right on .... On my Ford F350 I had my oil cooler replaced earlier this year. The pressure relief/bypass was sticking intermittently. Blew two filters at start up. Had to pull the oil cooler & replace the filter base. IF this happens to you in colder weather - chances are your bypass valve is sticking or stuck. Oil flows more slowly at lower temperatures due to thicker viscosity. Don't be too quick to blame the filter Jim
Looks like someone poured some used oil on the floor and threw a fram filter top of it to have something to post to me.
Had a similar experience with the wife's OT car last weekend. That one was my fault though. When I pulled the old filter out the seal separated from the filter and stuck to the reciever on the engine. Then I put the new filter on without realizing what happend. Oops. Started it off to back it off the ramp and it spewed oil all over the damn place. I stood there for a minute trying to piece together what just happened then I looked down at the old filter and saw the seal missing. DOH!!! Yeah...the wife was calling me "BP".
If you look at the filter bottom it looks very deformed and that is from over pressure. Probably hooked up backwards or a stuck OP relief valve.
They probably aren't that horrible but there are better options. They are probably less tolerant to over pressure situations.
update: found a K&N filter to fit my spin-on block, and didn't think twice about paying 3 times the price of the fram....lol
As stated before about black oil. Im not favoring Fram, cuz I hate them also. But I beleive that old oil didn't help matters any.
yeah, thats this weekends first job, change that oil....any input as to whats best to run in a flatty?
That's a beautiful engine, I'd check the oil pressure relief valve in the pump, I assume its the later short style for 8BA. For my pre-war 221 I left my existing oil pressure relief valve in the valley although some people shim them. I've heard flatties don't need a lot of pressure. I just hate to see people fire up those flatheads without water in the jackets, especially after all that work
firing it up dry isn't a real concern, so long as you don't run it for more than a minute. I'm going to pull the oil pump and also check the relief valve, thanks for the input.
I use Napa filters........ they are WIX, WIX make most of the industrial filters for trucks, been using them since the 60's never had a problem, stay with what works.....
I Rebuilt a sbc 25 years ago and the machine shop didn't line up the oiling holes on the cam bearings. Your grasping at straws thinking it the quality of the filter.
I worked as a mechanic for the Border Patrol in the mid '70's when we had Jeeps and and Ambassadors with 304's, 360's and 401's. The oil pressure relief valves would stick and the filter would grow to the size of the Hindenberg or explode! We used filters from GSA and never had problems with the other makes of cars in our fleet using those brands of filters, but we changes O/P relief springs and plungers regularly on the AMCs. What a mess they made!
WOW.... I never thought a flathead could get enought presure to blow up......must be a really bad filter.......thanks for the thread.
Holy Cats! I had no idea (until now...). I learn somethin' every day here on the HAMB. Thanks for the info.
Fram has had this issue before, I remember their filters being outlawed in motorcycle roadracing for just this reason, they would either blow up or blow off due to bad threads.
A word of caution about the K&N filters. If you can fill it up before putting it on, they are fine. If the application is one where the filter is "upside down", do not use a K&N filter. Their anti-drain back valves do not work. I used one on my HA/GR and noticed that after it sat for a while and I started it up, no oil pressure until the pump filled the filter. Same thing on my daily driver. This was two seperate filters on two seperate vehicles and neither one of the anti drain back valves would hold. Robert
Had that happen to a new race motor. We popped three filters in a row. Ended up the new oil pump pressure relief valve was stuck. High volume pump and the motor was in the engine bay of a mustang. You can imagine the mess that made.
I noticed you have the sending unit installed in the back of the block, I used a manual gauge there when I broke in my cam since I had no wiring or dash installed. That way I knew when I had oil pressure primed and monitored it while the engine warmed up.
