    I was having systems of a blown head gasket on my M3. My cooling system was pressuring within minutes of starting the car. The car runs great and doesn’t over heat whatsoever even with our 105 degree weather.

    So I decided to take the cooling system back apart and inspect the orings and water pump gasket to see if they were causing the issue. I changed out all 4 of the orings behind the water pump with some Viton Orings. This fixed the problem.

    Turns out ECSTUNING sent me two different sizes for the two orings on the small hard pipes, one 16x3 and one 18x3. The 16x3 oring was on the lower hard pipe that comes from the expansion tank and was sucking air causing the system to pressurize. It also caused major cavitation and was eating up the inside of my Brand New water pump and Tstat.

    I wasn't too happy having to tear apart my entire cooling system again due to a undersized Oring but at least it wasn’t a blown head gasket.


    Orings replaced are in Red.









    16x3 and a 18x3mm Oring!

    I saw this on m3f, glad you got it sorted out and that it wasn't a head gasket like the OP in that thread.

    I can't even imagine having to DIY a head gasket! I got lucky for sure.

    WOLFN8TR'S ///M Project Thread!

    It's been awhile since I posted any updates, here's some new additions. I finally got the Brembo BBK installed.

    The front calipers were sent off to Rally Road for machining to remove 5.5mm off the mounting surface to fit the larger 345mm rotors. You have to swap the crossover lines and here is where I ran into issues. The line was cross threaded into the front caliper, I had to use an impact to remove it and it took all of the threads with it! UGH!! The biggest problem was it's one of the machined calipers so I had to be very careful repairing it or it would cost me another caliper and the cost to send it off for machining! I had to drill and tap the caliper to insert a helicoil Beings the port is tapered this had to be done without messing up the taper on the inside of the port. This consisted of making a jig so I could operate! Drill an oversized hole, dremeled the excess at the back, tap and then clean out the back again with the dremel so the bleeder will seat properly. Also the helicoil had to be cut as it was to long. Beings it’s SS and made with precision so you can thread a bolt into it made it very difficult to get it cut down just right. Talk about stressful but in the end it worked!

    I was going to paint them a different color but the Red Brembo paint was in such good shape I decided to just keep them red and applied VHT clear. Baked them at 200 degrees to cure the clear coat. Went with some silver Brembo hi-temp decals. Also polished the crossover lines, pins and pad stops. "M3 now has 135k on it"

    Nice!! Pretty amazing repair job. How many miles do you have on them so far? What are your initial impressions?

    WOLFN8TR'S ///M Project Thread!

    Thanks guys.

    Ya the ECS guys really let me down sending mismatched Orings.

    I have about 500 miles on them so far. The brake feel is better with an increase in stopping power and less brake fade when they get hot. To me the best part is the “Bling”.
