    Yep that’s exactly as mine is with the bmw stamp so the original is a 272 cam. Thanks mate. Does the 260 cam make any difference with power?

    535i camshaft part numbers

    Hi M5. The cams def don’t have any colour on them. (Although one has red as I’ve just dropped in on my foot..ffs)!!! Mine is an 81 car but the head is not original. Original cam has 494b also stamped in it and 7 on the end while the other has 0408 and then 6 stamped on the shaft with 0 in the end. We know the new cam is out of a 2.8 car cheers for ur help btw it’s annoying as I used to post loads of pictures to help with this sort of stuff but phone picture sizes are so large now you can’t add them anymore
  4. So some of you will know I’m currently rebuilding the 535i cylinder head. The cam lobes on no.6 have seen better days with pitting. This has caused wear on the rocker pads on this cylinder. I have sourced a good used cam from my mate JAM as we thought they were the same on the 528 and real OEM confirms this. However the cam in my car has a different number to the one we have spare. Original cam reads 1250 057 while the new one reads 1250 057.1 it looks the same and could be an iteration but I wanted to check before swapping
  5. Sorry for the late reply. Yes I did see it.

    Hi Mick. was new to the car 30-40k ago. It’s was off a race car and was raced for 3 seasons before it was put on this car. Yes agreed doesn’t make sense. Wish I could post all the pictures I have but they’re too big to load here. Will have more info from the builder this week. Valves look fairly shitty tbh. Once the head is checked they’ll be pulled, cleaned, replaced if required and re lapped so head will be good hopefully. Beginning to suspect rings but the wet comp test made no difference to comp. gasket was also showing signs of leaking all around 1 and between 1-2 and 5-6

    Just to update. Head is striped. Did a very basic tip petrol in upside down head chamber. 1 and 5 l leaked in less than a minute. All the others including 3 were fine so who knows. It’s being dropped at the engine builder tomorrow for pressure testing. Then if it’s good I’ll check the valves.

    Engine on TDC. Most ancillaries removed now so almost ready to pull the head. Head bolts. Are we undoing in a pattern to reduce head stress? Reverse of tightening?

    That was my thought unless someone knew a reason

    So which gasket is considered the correct one?
  12. Joss

    Won’t cause low comp. will cause oil on over run. Also I changed them not ling ago.

    Well mate. We’ll have to see. Here’s hoping it’s a cheaper fix

    Indeed. Well it’s head off time. So what are we betting on? No blue smoke, no chuffing back up inlet, no coolant loss or oil mix And rockers checked. None broken Place your bets people Cracked head Burnt/chipped exhaust valve coked exhaust valve
