Knock on startup

  1. Hi all

    I have an issue with the mrs 250cup. On engine start up there is a clunk when the engine fires up. Sounds like its coming from the drivers side - is it possble that the top torque mount on cam cover is worn or should i be looking at the other mounts.

    Cheers Jon

    Yeah it'll be the engine mount, mine on my R26 was the bigger one but could be either.

  3. Had battery tray out and checked gearbox mount which seems ok. All the mounts look fair condition typically, will start by replacing the top mounts and go from there.
     
  4. Try and get a video of the noise, could be anything, no point spending money on parts you might not need

  5. Is it a knock or a rattle. Best bet is getting a video up as mentioned above.
     
  6. Probably either of the sway mounts

  7. Its a knock. Ill try and get a vid its basically a single clunk when engine moves on startup.
     
  8. From new the engine moves quite abit on start up, i uprated the lower one to a vibra technics one and foundit alot better once worn in.
     
  9. Did you fix the clonk on start up ?
     
  10. Nope still no joy, and reluctant to fire the parts cannon at it
     
  11. I have only got it now if its cold outside or the car has not been started for a while. Warmer weather and no noise !! If I find it will let you know, its one of many small things I'm working on lol
