      Replace the engine mount arm hardware with something new/higher grade. I snapped two bolts off when trying to remove the engine mount arms from the block when I first got the engine.

        I believe Jordan's S50 car did something similar. Or the hardware backed out or something.

        Keep them coming!

          Possible new coolant "spider" hose they can explode nice and randomly

          New rubber grommet dealios for VC. They are always rock hard and weep

          I try to keep stock of the clips the secure the ICV into the intake manifold. I always seem to break those damn things when removing them (new ones are a good idea, new rubber seal and all)

          Fuel lines going from m20>24v seem to be a touch on the short side, I need to extend my rubber lines a bit to make it easier to reattach. Same goes for FPR>manifold vac line, I need to replace mine & add a vac block

          This really has nothing to do with reliability or upgrades. Just annoying crap that I've noticed

            Maybe its different for the e34 oil pan, but s52's and probably the rest of the s/m5x group are notorious for gaining some lifter tick after a hard autocross run. A lot of people run their s52's a quart over full to help alleviate the problem (apparently it takes like 4 quarts above full to start having problems with the crank splashing and foaming the oil) but an oil pan baffle will also do a lot to improve it. Apparently it isn't a huge deal as far as damaging your engine, but it's certainly annoying. 

            If you're a big baller with some extra spending money you can do an s54 dual pickup oiling system (this will only fit e36's, not swapped cars unless you have one of those fancy rear sump subframes/pans), but it's probably not worth the 1.5k+ on anything other than an expensive, fully built race motor.

              If you're newly acquired m52 doesn't come with ground straps get some nice ones. Couple companies have aftermarket ones (chase bays, catuned, can't think of any others)

              Ground for coilpacks too maybe

                I overfill by usually a quart or so.

                Lifters get loud after 3/4 runs.

                        It's not so much the "I'm going to blow it apart" aspect. More so the "I've already broken 3 of these" lol. Not to mention the fit when the plastic one is "clipped In" just doesn't feel snug

                          If your crank damper has been off and on multiple times get a new key that locks the crank to that damper mount. I sheared one off and that was a big headache. Get a new crank bolt to.

                          That stainless clip is tits!

                          The water pump you picked up from me is a Stewart if I remember correctly.

                          Just don't put a lock washer from ACE HARDWARE on your oil pump nut and all will be well.
