    Clunking from bottom end VN s1 V6

    Well I've taken the VN back to the mechanics. He said he noticed the rattle after he'd tightened all that was loose, but he'd assumed that since it was an old car (that I'm trying to FIX!) it would have a few rattles. I told him that it's ridiculously loud and it can't actually be having no...

    Clunking from bottom end VN s1 V6

    Torque converter ended up being loose according to a mechanic that I took the car to. (could not take the exhaust system off) But the problem doesn't end there, unfortunately. I started the car before and there was no rattle! I thought all my problems were solved, but there's now something...

    Clunking from bottom end VN s1 V6

    250,000km, had all the services. I'll tear the entire exhaust system off tonight and have a better look, not sure if I want to drop the gearbox though, could be a lot more work than it's worth.

    Clunking from bottom end VN s1 V6

    No worries. I've loosened the whole inspection cover, but as was said, there's an exhaust in the way. I cannot fit any tools up to take it off the manifold, and as far as I can see there's no other way to take the exhaust off.. Can anyone explain how exactly I do take the exhaust off this thing?

    Clunking from bottom end VN s1 V6

    What's the easiest way to access the flexplate to a) check to see if it's loose/cracked, and b) replace/tighten?

    Clunking from bottom end VN s1 V6

    On further inspection (taken belt off, ran motor) it definitely sounds like the clunking is coming from the rear of the motor. if I grab the harmonic balancer and turn it there's a metallic clunking coming from the rear of the motor. It happens maybe once or twice per full rotation of the...

    Clunking from bottom end VN s1 V6

    I just want to clarify, as I understand that it's most likely the harmonic balancer (I've even got a new one to put on!) I just want to be sure. Loud rattling/clunking started a couple of months ago. Only at idle (I can put my foot on the throttle a bit at the lights and it goes away) and...

    89 VN gearbox/engine/??? issues

    Hi, Just had a second hand installed - had 140,000 on it. Drove beautifully for maybe 1,200km, shifted well in every gear, under full acceleration it performed well. Just today when I went to start the car it backfired and part of the air box blew off. I continued to try to start it, and...

    Memcal socket install

    Does anyone have an xdf file for a series one VN they can upload? I might mess around with my own tunings for a while.

    Memcal socket install

    So what's the deal with a 512k chip where the actual binary I'm using is only 32k?

    Memcal socket install

    Simple question: What reprogrammable chip do I buy for my series one VN? I want to try a few different configurations on it. I've got TunerPro, and I'm thinking I'm going to buy sockets/cables to do it real-time.

    rb30e in a vnbody

    Yes, I'd personally replace it with a new Buick and work that. The RB30 is a potential engine, though.

    1989 VN - Temp not coming onto the gauge

    Okay, well I'm gonna do the temp sensors this weekend... I think it's actually running wrong, the heater doesn't work unless it's idling in traffic. What I mean is, it blows cool air unless the temp gauge gets up past the second notch. I'll do them and report back!

    1989 VN - Temp not coming onto the gauge

    Okay, sweet. I just wasn't sure if it was getting to temperature - wouldn't want to cause engine damage. If all of them run that cold though, then that's great, cheers.

    1989 VN - Temp not coming onto the gauge

    Hi, I recently picked up a series one VN v6, but it runs cold all the time. After 5 minutes of running it comes up between the cold line and the first line on the gauge, but it doesn't get any warmer. Even in traffic, it won't get above the second line. If I sit in a drive through/traffic...
