hey all im not sure if my timing has maybe skipped a tooth or something as my motor seems like it is only running on a few cylinders or something and runnning like a bucket.

now what i wanted to know is if it had skipped a tooth or something then would i have damaged valves as well??

or do i just have to get the timing right...if that is the problem

It will bend valves if too far out -not sure how much it needs to be though - I suspect one tooth maybe ok.

If drivable I have found some Nissan Dealers with a CONSULT box can diag quickly at low cost.

Actually Blackburn Nissan has done three such checks over a few years for me for FREE.

When I needed orig Nissan parts I bought them there needless to say!

One tooth isn't enough to get the valves to hit. I've done it myself when installing the adjustable gear. I actually fitted it correctly, but it ran so crap with the standard -4 degrees that I thought I must have put it on one tooth out, so I put it back on in what I thought was correct and it ran even worse. So I'd say it's ok to go at least one tooth off, and an extra 4 degrees of adjustment :(

      You should have got a Maine Coone then. Only thing is they're big. But so cool, and just like a dog. Or, just get yourself a high performance dog. That'll teach you for wanting Parkour indoors 😛

      Are you thinking of Bens R32? I don't remember if his went through the bonnet itself, but it went through the chassis rail. Brad (RISKIN) bought it, and turned it into a track car. It's funny how anti people are of Jim Berry now. I remember when I pulled mine out (during an engine change) and inspected it and found it cracking badly. At that point in time so many people were even on SAU, were so pro Jim Berry, and that was after Bens GTR exploded his quite publically.

      That's one of the reasons I got that breed, they look weird, the other reasons are they small, they are very vocal, and run around like they are on crack, I didn't want a breed that just sits around, these two are like kids on red cordial  My daughter has one, and it's a laugh riot, constantly doing Parkour around the house, sits on her shoulder, plays catch, and constantly runs around the house taking turns chasing the dog around, her Bermese though, just lays around with constant bitch face, and just looks on in utter disgust at the cat and dog playing together

      I'm getting PTSD flashbacks seeing that name again.  With my turbo swift, I got 1,500km of street use on a Jim Berry clutch before it exploded and took out my input shaft with it.
