Oil cooler install

Postby JayMac » Wed Jun 20, 2012 10:45 am

I plan on installing my oil cooler this weekend and am trying to make sure I have everything covered. I am going to mount the cooler on it's side and was thinking that I should have the oil go in from the bottom.

Does anyone know what flows where from the passages on the block.
Here is a shot of the Euro housing. I think on the regular one we have a flow valve. This is a thermostat for flow to the cooler.
Image
You can see my finger through one of the cooler ports. I read that the thermostat does not close completely so I am thinking that the flow out to the cooler is the port with my finger but not sure.
Image
This is looking down the top of the housing. It looks like back flow valves but I am not sure. Does the oil come up the center to the filter or up the sides and down the center to the engine, ( I think this one)?
if the oil goes to the engine via the center I can pour parts cleaner in there to see which port it come out on the bottom. Thought I found all of this in a thread somewhere but now that I need it I can't locate it!
Duh!

On the top down shot one of those might be a pressure relief in the event of a clogged filter. The other could be a drain. I start pouring and post some results of what comes out where.

Okay, figure this out no specifics just some common sense. The top is after the filter. Your vanos line is threaded there. You wouldn't send dirty oil into your engine, neither would BMW.

Here is another question I have. Any ideas or thoughts. I have read post about leaks from the housing and the ports being sealed with a seal and some type of clip. The Euro housing has what appears to be a threaded cap on this port. It would be the one below the right plug.
Image

Since the oil pressure sensor is just for an idiot light why could I not move it here and use the other port for a real pressure gauge? I believe this is on the feed side but since pressure ranges from 7 to 60 it should read. Right?

I am not sure of that. How large is the bolt. I took the cover off thinking it was M12 and it was huge, maybe M16 or larger. The cover takes a 10mm hex and the plug is at least 20mm wide. Anyway I will play with the gauges later. I am using Push Loc fittings and the blue hose for multiple reasons:
Weight
cost
ease of assembly
A little tip when you put the hose ends in, if you have any parts cleaner or solvent, soak the end of the hose in it for a few minutes, less than 5, the fitting will go right in. Since I am using GUNK I then rinsed with water and let dry. Works really well.

Doing a little test fitting since I can't finish up until I get the spacers from VAC. You loose the cooling hose to the back. Here is the alt held in by the bottom bolt. A little tip. When putting the alt in start with the bottom bolt first. If you have a piece of fine sand paper, lightly sand the inner mount of the alt and the outer face of the oil filter housing. Since we are dealing with some old parts you might have a little corrosion or dirt. If no paper is available a scouring pad from the kitchen will suffice.
Image
Notice that the top bolt is not in. The blue caps are on the AN fittings where the lines will go. Notice they are already hitting the duct. You can either cut to fit which seems like a lot of work or remove the cover altogether. The e36 is the only car I have ever seen this on. Here is a shot of a cooler plumbed in on a e46. No duct work here.

A set back and then some progress. Got the spacers in from VAC for this job it is the M50 spacers and not the M54 so those will go back. I did a test fit and thought I would be good to go. Threaded in the inner bolt and just put in the outer to hold up the power steering pump. Pulleys line up so lets bolt it in. I can't get the outer bolt to go in. I think there might be dirt and crap in there so I put my ratchet on there and it still wont go. I then realize that this hole is threaded. On the original housing it is not. No worries there I will just get a metric bolt that is fully threaded. My plan is to thread through to the nut on the power steering bracket. That wont work either because unlike the original housing tha hole does not go all the way through. You can see a mark where it would but it is not there. So I slowly threaded the bolt into the metal and foced the hole open and then cleaned it with a Dremel Tool.

Here are the spacers from VAC and the inner and outer bolts. Short one thread in both housings.
Image

Test fitting and and finding another issue to deal with.
Image

There is no hole here on the Euro housing so I have to take the whole thing out and solve this.
Image

Since all of the housing bolts are different sizes you can label or do this. Not my idea but worked really well. Out of the housing into the cardboard. You don't mix up or lose. Washes stay right with the bolts.
Image
So I am now going to drill out the threads on the housing. The holes are different sizes on the two housings but the bolt threads are the same. I know it makes no sense but trust me, there is about a mm difference. Since the inner is threaded on both units it hold the pump/pulley out in place but I wanted the outer hole to be as small as possible. I grabbed a handful of drill bits and found the first one that got resistance from the threads. I ran it through. Went up one size and the bolt went through. The nice thing is that the center of the housing is where the hole is the tightest so it should not stress.

So back to this picture. Notice the space between the bracket and the oil filter housing. A few washers should do it.
Image

Outer bolt is now threaded into the nut that is contained on the rear power steering bracket, just like the original housing. Lines on tommorow and test for leaks.Image

Hey guys quick question from ignorance. I have everything ready to test fire and am going to run the car without the cooler hooked up. I can test the housing for leaks and the AN fittings. First time with this filter. I am just running a Purolator for the test and then over to a better oem. It seams that I need to crank on the top bolt quite a bit. Am I correct in assuming that it is both okay and compressing the two gaskets on the filter?

Finished up and I have oil everywhere. Not what you think but here are the details. I popped off the protector part of the back of the alternator cooling housing. Thgis will allow me to keep all sort of crap off the electrical connection.
Image

I have read where removing the alternator and replacing it are a problem. I did not find that to be true. Here is what I did. I set the alternator in place. Prior to that I lightly sanded the surface point to remove any corrosion or dirt. Still pretty tight but it falls. The bottom bolt is a pain but you can get to it. I started with the top and once it was in just wiggled the alternator. It did not go. So I reasoned that I might be past the hole for the bolt and lifted the bottom towards the fender. Bolt goes right in and torque it down.Image

All the pulleys are finally on the same plane. Just a note you can use a power steering pump from an OBD1 car and forgo the spacers. Nice picture of it in the Bentley on 119-5.
I needed ALL of the adjuster for the belt to fit over the pulleys so it makes me think there is a slightly larger belt out there that should be used. I double checked it and it was tight going over the ribs and found it was up on the crank pulley so I have a little play but much less than before.Image

I ran the car without the cooler hooked up to check for leaks and found one but it was the AN cap so no worries there. The housing is dry and so it the AN plate. Time to finish the hoses. I just have them looped to the cooler so I put the AN fittings on the housing. Marked the hose and cut it with a shears used for tree branches. The push lock hose is much easier to deal with than braided. I soaked the hose in solvent to expand it. GUNK CARB AND PARTS CLEANER. Soak for 2 to 3 minutes and you can press the fittings in.
Image

Wipe down the outside with a shop towel and fire it up to flush the lines from what ever solvent is left in there. Start the car. After about 5 seconds I have oil spitting from the front of the car. I think it is the used cooler I bout but forgot that I flushed it and pressure tested it. IDIOT, forgot to tighten up the bottom AN fitting so I have about 1/2 quart on the ground. Going to get my ass chewed for that. Off to the store for some cat litter to soak up the oil. Just finishing up and I hear a pop from behind me and then hear liquid hitting the floor. I turn around and find my Accu SUMP has burst. This is on my Cobra replica.
Image

Image

This engine has not even run in 6 months and I have no idea where the pressure would come from to do this. Notice the threads failed. THIS IS THE SECOND ONE OF THESE I HAVE HAD BLOW UP. Last one was on the track. I can't believe I was actually in the garage when it happened so I was able to contain it otherwise there would be 3 more quarts on the floor heading towards the street.

Anyway oil cooler in and after a 10 minute run no leaks. Test drive to work tomorrow with all the need emergency crap.

No worries, I am going to switch over to the Moroso product better built and they have better tech help. It was just crazy that I happened to be standing there when it happened. Test drive in 30. 70 mile total with AN wrenches towel and oil just in case.
