kane Posted January 2, 2016 Share Posted January 2, 2016 I'm getting conflicting stories. If it's interference then it's basically scrap if the timing belt breaks. But if it is a non interference then i can repair it. Autozone claims it is non interference but rockauto claims it is an interference. Anyone happen to know the truth???? 2000 nissan pathfinder v6 4wd 340,000 miles on her and was running like a top before the belt broke. Link to comment Share on other sites More sharing options...
Slartibartfast Posted January 3, 2016 Share Posted January 3, 2016 2000 model is a VG33, which is interference. It's less interference than the VG30, and I have heard of people getting lucky, but it does the ability to knacker itself. You could just throw a belt on it and see if you can hear any dead spots while cranking. Autozone may be confused because there were non-interference 3.3s made... for use in a rebadged Quest van sold by Ford. If the valves are in fact shot, you could just swap out the heads. At 340k, though, it might make more sense to find a lower-miles motor to start with. 1 Link to comment Share on other sites More sharing options...
kane Posted August 2, 2017 Author Share Posted August 2, 2017 She's a non interference. Changed the belt, water pump, pulleys and fired her up. Runs great!!! 2 Link to comment Share on other sites More sharing options...
Citron Posted August 2, 2017 Share Posted August 2, 2017 Nope, interference. You just got lucky. Link to comment Share on other sites More sharing options...
adamzan Posted August 2, 2017 Share Posted August 2, 2017 I'm not so sure anymore. I've seen a few of vg33 break recently and nothing happened. Maybe they are less interference than the 3.0? Regardless people should just change the belt on time and avoid the annoyance of a breakdown. 1 Link to comment Share on other sites More sharing options...
Slartibartfast Posted August 2, 2017 Share Posted August 2, 2017 From what I've read on here, the valve reliefs on the 3.3 are cut so deep that the valves and pistons only overlap ever so slightly, so you'd have to have a valve at full lift at the same time the piston's coming up to have a problem. The smaller the overlap, the greater the chance of getting lucky, which it sounds like a lot of people do with the 3.3. Either way, good to hear yours lives again!

Saturn Posted August 4, 2017 Share Posted August 4, 2017 Anyone have knowledge with the VQ35 on this matter? I know my timing chain will make noise before it kicks the bucket, but I'm curious as to whether it's high interference or not. Link to comment Share on other sites More sharing options...
Pathypop Posted August 5, 2017 Share Posted August 5, 2017 340,000 miles on her and was running like a top before the belt broke. 340k Miles ! That's the most I've heard of. Any history of major repairs (rebuilds, trans work, etc) to achieve that? Keep going! Link to comment Share on other sites More sharing options...
2milehi Posted August 7, 2017 Share Posted August 7, 2017 This shows it pretty good. VG33 on left and middle, VG30 on the right. Link to comment Share on other sites More sharing options...
