OIl System help please.

OK guys,
My '73 1275 is about ready to go back in the car and I've run up against a small but quite annoying problem. I added the (Moss) oil cooler kit to my car a year or so ago. Now I was going to add a remote oil filter kit to the car. The problem is that the kit that Moss sells under the name "Cobalt Precision Automotive" uses hose fittings that I can't seem to locate. It is like a reverse -AN fitting where the male flare is on the pipe end and the female flare is on the fitting. I'm hoping one of you out there has come up against this problem already and found a solution.

Also, while we are on the topic, should the oil go trough the cooler and then to the filter or through the filter and then to the oil cooler?

Thanks,
JACK

It would seem to me that I would rather have clean filtered oil passing through the cooler rather than filtering out the bad stuff after it had a chance to have any possible ill effects on the oil cooler's function.

I agree with Nelson, filter first then cooler. I'll bet if you let your fingers do the walking thru the yellow pages to hydraulics suppliers you'll find the fittings you need. My 2 cents!!

British car like the MGB in their orginal oiling pattern have it backwards, they take unfiltered oil to the cooler than back to the filter housing, that the wrong way to do it. Jack, basicly you are trying to do the same thing we do to the race cars, take the oil from the exit orfice at the rear of the block to a remote oil fitler housing then to the oil cooler and then back to the engine. Here's what I suggest you do, call Winner circle and tell them what you are doing, they sell a block adapter to go where the oil filter housing did go, it will tapped for a NPT to AN fitting, you'll need a special fitting for the rear of the block that goes form the straight thread to AN (I use AN10) then if you have not bought a coil cooler yet, just buy it with AN male fitting rather than BSP, but Pegaus Racing deas sell soem BSP female to AN adapters, defiantel go with bradie hose and Aeroqip type fitting, you can buy that stuff off ebay for pennies on the dollar and with a vice and a few simple tool assemble your own hoses.

Here's the special fitting for the block.

Thanks everyone and thanks Hap.

Hap, to answer your response, I had already switched the outlets on the new block to -AN not knowing (or rather not remembering ) that the fittings on the oil cooler and old engine coming out of the car were not the -AN but rather the BSP. So now I have a block going into the car with a -AN adapter on the outlet and a -AN adapter in place of the stock filter assembly at the return point to the block. I have a remote filter assembly with two -AN fittings. All my hose connections are female BSP.

So, leaving block -10AN to filter housing -10AN: No problem, have it.
Leaving filter I will need a 1/2" NPT male to 1/2" BSP Male adapter
From oil cooler into block I will need a 1/2" female BSP to -10AN female adapter.

I hope I can find all of those.

If not, what if I put the original oil filter assembly back and had the oil cooler go back into that? i.e. block->filter->cooler->filter->block That is the connection point that exists now. Would it be bad to have two filters in the system? Would it be too restrictive? Just thinking out loud.

Thanks guys. And as a side note, this is my only daily driver. It went down with yet another blown head gasket so I'm swapping in a fresh rebuild ahead of schedule and that's why things aren't totally straightened out. I need everything to go well as I'll be breaking in a fresh rebuild on this motor so having everything sorted out and safe in advance is crucial.

Wish me luck!!
JACK

Jack, you can get both of those adapter fittings at Pegasus Racing, www.pegasusautoracing.com

.

So, leaving block -10AN to filter housing -10AN: No problem, have it.
Leaving filter I will need a 1/2" NPT male to 1/2" BSP Male adapter
From oil cooler into block I will need a 1/2" female BSP to -10AN female adapter.

I hope I can find all of those.

Thanks Hap! My order has been placed.

Here's the end results after a few quick adapters for the adapters! :laugh:

Some day I will ebay these british parts and swap it all for the more readily available -AN stuff. This'll do fer now. :wink:
