911 oil filter "drama" Options

[Keith914]

I am at final stage of completing my 2.7 911 engine install project. All external oil lines are AN12 stainless steel braided hoses and fittings. I have the scavenger oil feeding directly into an oil filter which is mounted to a bracket with 1/2" fittings for the in and out and for the nipple that the filter screws onto. While starting the engine, as soon as rpm's exceed about 2000 the filter O ring pops out and oil leaks massively. Same result after several attempts. I have a K&N filter that has a large O ring that is not as secure in it's groove as say FRAM filters I am familiar with, and which worked well with this bracket fitting when I had my Type IV in the car. I will be installing a new bracket shortly that has 1/2" in and out hose fittings but a 3/4" nipple for a new typical 911 filter which has a matching 3/4" screw on female fitting. I decided not to install an oil thermostat as I live in a warm climate here in S Cal. Any advice will be welcome.

I think 1/2" is to small as stock would be 5/8" internally in the tank. This would increase oil pressure to a certain degree. That said something else seems wrong.

Is something stuck on the oil bypass on the engine? Also i would use the oc54 filter myself.

Could you explain how you have the oil filter mounted better,
Is it on the tank?
Or are you talking about a remote filter adapter like how you would do full Flow on a T1 or 4?

What brand and # filter are you using?

Fram filters are shit, I used to be a HP-1 lemming till I cut one open.

The oil filter bracket is located on the original battery tray - battery is now in front of car.

I know your trying to save money, but if you bought an aftermarket six tank from mb911 your car would most likely be running now. I would be surprised if it's related to the engine.

Not sure what you mean by oil filter bracket.... I'm assuming you mean remote filter adapter.?

Yes, like this:

Should that remote require a Mann filter designed for a 4?

[Steve]

If your going to go that route, I would check out how Patrick Motorsports does it.
http://www.patrickmotorsports.com/part/rem...ount-set-an-12/
They also list the project cars with pictures on how they use the remote oil filter console.
Stock oil tank would be less work....

(IMG:style_emoticons/default/agree.gif) You can use a type 4 fillter, Mann, Bosch, NAPA gold.

You will pop the O-ring on any cheap filter with even a VW type one oil pump.

Way under sized for the large 911 /6 oil pump. You should at least use a remote filter adapter for a tractor/hydraulics.

Patrick's console looks like a well made part, but has the same oil in and out AN 12 fittings I will have on my new bracket, and I am guessing that it has a 3/4" nipple for screwing on the filter. I have a new MAHLE filter which has a 3/4" female "nipple". I am going to cautiously try this filter with the new "3/4" bracket/adapter combination before changing to other solutions you have suggested.
Do you have a "adapter for tractor/hydraulics" reference? - I will look on Google.

[Mark Henry]

Same thing you have but in 1" NPT, any hydraulic supply house.

I should have mentioned my new filter is a MAHLE OC54 from Pelican 911 catalog.

Thanks and I am pleased you are enjoying the 2.36 Ltr.

If it's a mahle I'd look elsewhere than the filter, after the filter it's suppose to just dump into the tank, no real restriction.

Just a thought do you have the flow into the filter backwards?
It could be messing with the filter by-pass valve.

Mark, Thanks for all your input.

First, flow direction is correct, - this is a remote filter mounting, and is first in line from the scavenger pump - oil flows on to the front cooler, then back to a custom built tank located in the engine compartment - no thermostat - S. Cal!

Next I owe you an apology - the inside non-threaded plumbing in toy old bracket -picture above, is 3/8'" diam, just measured again, and the inlet and outlet ports are 3/8"NPT. My new bracket, just delivered, has 1/2"NPT inlet and outlet ports with corresponding internal plumbing non threaded - much better than smaller old bracket. the filter spin on nipple however is the same 3/4"-16 as the older unit. I need to get AN12 fittings to connect the hoses to these larger 1/2' ports and a good filter to spin on - tomorrow will report back.
