  1. 2021 Mojave P0300 missfire - suggest engine swap by dealer, replaced head/cams instead and now...

    Further to that.... I got to thinking, it looks almost like a valve timing issue, rather than compression... am I right in thinking that?
  2. 2021 Mojave P0300 missfire - suggest engine swap by dealer, replaced head/cams instead and now...

    Got the compression numbers from the dealer after the head and cam/lifter repair- Cyl 1-3-5 165/180/175 Cyl 2-4-6 135/130/138 - obviously cyl 2-4-6 they say are causing the mis... How long do you think I can run her before I start having some major issues? Is there an additive I should be...
  3. 2021 Mojave- 72k - P0300 Miss fire, and now a complete engine replacement??

    Mojave has been at the dealer for over a month now, the Dealer suggested putting in a 64k KM (I'm in Canada) used 3.6 for $13K, I thought this was a stupid solution as the issued could very easily happen again... So I decided to go with the head replacement for 2-4-6 (left side) complete with...

  6. 2021 Mojave- 72k - P0300 Miss fire, and now a complete engine replacement??

    I think I am going to replace the right side cam, all lifters and rockers... we'll see where that takes us.. replacing it with a identical low milage pull will set me back around 15k-17k cdn, i would rather put that money towards a hemi or trade the mojave in when we get a more substantial...

  8. 2021 Mojave- 72k - P0300 Miss fire, and now a complete engine replacement??

    the video says he wasn't sure if there was more damage to the engine.. so I guess that's why? I wasn't having any issue at all except at load (over 5K rpm)- I'd be happy just to run it till it crokes at this point...

  13. 2021 JT CEL - Misfire cyl 3 under load only

    ****** UPDATE****** After the last P0300 I decided to take it to the dealer I bought it from- Removed the manifold, Rockers are fine, cams good- then they started testing compression and..... it's all over the place... Removed the oil filter and mine is on the left in the pic, looks like its...
  14. 2021 JT CEL - Misfire cyl 3 under load only

    Appreciate the advice, we installed new coils and got the P0300 code again, this time 4th cyl... seems like it is the 2-4-6 bank that is giving the issue, will pull the valve cover and take a look at the rockers and lifters....
