    Hope none of you R53 fans ever need a camshaft... I have just placed my FOURTH order for a new camshaft. First attempt, vendor couldn't find the part in their warehouse even though their system said they had it, order canceled and refunded. Second attempt, vendor canceled the order a day after confirming it, refunded. Third attempt, vendor bumped the shipping date back by three weeks a few days after confirming the order. I called them this morning, they said it goes like this: I placed the order with them, they placed an order with a Mini dealer. The dealer got back to them and said they have to order it from Mini USA. Then Mini USA said there are none in stock in the US and they have to order it from BMW in Germany. That changed the lead time to 3 to 5 weeks as of today, but the guy said realistically that will change to be more like 6 to 8 weeks. I'm not optimistic about the global supply chain getting back to normal that soon anyway, so I think I can kiss that one goodbye too.

    I just ordered a used one from Allmag. They have three. I wish they shared more photos, but I picked the best of the three based on the few photos they have of each one. At least the thing is in stock and will actually get sent to me soon.

    You could write quite a story about your trials and tribulations.....oh wait, you have.:) The good thing about ALLMAG is that they give you a satisfaction guarantee along with a warranty. If’n the cam shows up and you do not like its condition you’ll be able to send it back. When your were looking for cams were you only looking for OEM or did look for some aftermarket street cams ?? The good news is that ALLMAG ships quickly and from what I purchased the parts showed up as advertised.

    You get better bu doing we have all been there. Be careful, you get the timing off too much you will bend a valve.
    So close!

    I’m brand new here, but very experienced with cars, wrenching, fabricating and modifying. All I can say is I am impressed!
    Fingers are crossed for you and your son. I just bought a r50 with 250k miles that runs and drives great but I know I’ll be doing what you are soon.

    I just remembered that I didn't reset the ECU with the test menu procedure and all that like I did last time I had everything apart. Seems a long shot that the problem is caused by not resetting, but I may as well do that process first to rule it out.

    Thanks for the welcome I’ll start a thread at some point.
    As far as your thumb slammed, if the nail starts to swell, take a tiny drill bit and drill a hole through your nail slowly by hand or take a hot needle/pin and poke a hole through the nail to relieve the pressure.

    hopefully you get the car sorted

    If you kept the chain on the sprocket the whole time then you should be properly timed. The only way I know how to check this is to pull the timing chain cover and count the links or just reset he chain to the marks on the sprocket.

    I would pull the timing chain cover and check/reset the timing. Since the motor has been run the timing marks on the chain will not line up with those on the sprockets. You can count the links of chain between the crankshaft marks and the cam marks, see picture below for reference, but you might as well pull the chain and realign it with the marks. If you have to rotate anything to get them aligned, then your timing was probably off. If that's the case, a leak down test will tell you if you bent a valve.

    Everything @myles2go said. Sometimes you can tell if a valve is bent by looking at the top of the valve spring. Set the cam lobe point away from the valve. If it is the spring/top of the valve is shorter then the other valve springs it is bent. Some cars the rocker will be looser than the other rockers if the valve is bent.
    Do not run the car till you do what @myles2go said and you know the valve is not bent, you don’t want it to brake, that would be new motor time. If someone tells you, you can straighten the valve don’t! That’s a good way to buy a new motor. Also if the valve is bent their will be very little compression on that cylinder.
    I wouldn’t order parts till you check everything. If it is a bent valve you can replace that one valve.

    don’t give up. We have all learned the hard way.

    On the thumb: I hold a needle w/ a pair of needle nose pliers, heat it to red-hot in the flame of the stove and then burn through the nail in the middle of the blister that's trapped underneath. It only takes a few seconds and I've never felt any heat through the nail (the nail is dead material but there are nerves under it usually... padded away by the blister). Be prepared... the blister is under pressure (the pain you are feeling) and it might squirt a bit when you first break through. No need to reseal... just let it breathe and grow out.

    And now back to your normal non-gross MINI content!

    I might be closing in on a happy conclusion. The car is back at the shop that I've referred to a few times in this thread (going on five months now!), and yesterday they confirmed that it is mistimed, and that's causing the P03041 camshaft sensor error. They said it's off by five or six teeth, which they said is about 30 degrees. No concern about a bent valve for now. So I'm going to have them re-time it. Their mechanic said he thought it still sounded like it had a misfire, but that could be the bad timing. If it does, it is significantly less pronounced than the misfire I've tried to solve all this time.

    I was so close... I took off the wheel on Saturday morning to open up the timing cover and re-time it myself to see if that was the problem, and then it hit me that I don't have the rented pulley puller to remove the crankshaft pulley I put on there. That's when I decided I just need to stop! By the time I wrote my last post above, on Saturday night, I was just worn out by the whole thing. Now it feels good to know that I was a pulley removal tool away from solving it myself if I had re-done the timing this weekend. But the shop will do it correctly for sure, and they're also going to give me a sense of how serious my leaks are (oil and power steering). I'll update again when they're done, possibly today but more likely tomorrow.

    For reference for anyone now or in the future who understands these graphs (I do not), the shop shared these images of their timing check that shows the mistiming. Maybe someone familiar with these readings will get some use out of it as reference at some point.

    Part of the battle is knowing when to call in the experts! Good work! Hope that the car is up and running well soon!

    it seems like I've had PS line leakage / replacement for every 4-5 years or so of MINI ownership. I had the work done more than once on my first R53 and had to do it almost immediately upon acquisition of my current R53.

    Excellent thread! Your right metal in the pan is not a good sign. The bottom end of that motor is built like an anvil. I can’t imagine whet is making metal.
