Hi all - has been quite a while between posts/updates. Some health issues (heart) had put all on hold for quite a while. Am getting back to the build and, after the completion of the engine overhaul, got all back in and am closing out on some final areas. As part of this, I am removing most of the anti pollution gear, trying to simplify the vacuum lines and also fitting the Redline Weber kit. That has all progressed reasonably well apart from some connections not being clear as to what goes where and what can be deleted/capped. I made various sketches and notes when I dismantled but am no finding that some of the component markings have been lost in cleaning and handling. In working through the pollution gear, I have been using the other excellent write ups on the forum although ones specific to the VG30i are few and far between.
So, with all of that, I was hoping to get some advice/clarity on the following - numbers reference in the pic - tried uploading the pic but am getting message saying I can t upload. Hopefully this link will work - goes to same pic in shared dropbox file. https://1drv.ms/u/s!ArhBM0TeWGIago8uxSJwDKmMOe_snQ?e=achdZt :
1. Is a vacuum line under left side of carbie. I believe this goes up to the purge connector on the canister but, if not, is this OK to cap or should it connect to somewhere else?
2. I believe this is a loop connection to the AB valve on the air cleaner. Can this be capped when I remove the AB valve or something else?
3. I wasn't sure on what this one was, whether vacuum or coolant (currently radiator/coolant is dry so wanted to sort before filling up fluids). If coolant, where is this leading to for connection? If vacuum, OK to cap?
If the pipe from 1 in the pic doesn't go t the purge connection on the canister, where does the purge line connect? As the TBI has been swapped to the weber, very limited vacuum line connections now.
And the really strange one, underneath the front (drivers side here in Oz) are the metal fuel lines that come up the filter and return and, while they are all OK, in the same group is another steel line that departs this group and then goes across the front cross member to about mid way with right angle bend and then an end that looks like a flared end but a few mm back from the end of the [pipe, suggesting a rubber pipe connects to the pipe. The breather line from the fuel tank is connected and is connected to the cannister already so doesn't appear to be mixed with that. Am hoping to get a pic of this one on this coming weekend as well as try chasing it back along the length of the terrano underneath.
Sorry for the long list of questions but i am really hopeful that some sage advice will be forthcoming and avoid me contemplating putting a match to it from frustration 🙂
I do not own a Pathfinder but my wife and all our 4 kids have had or currently have Nissan products. Our oldest daughter has a 2014 Pathfinder. My son had a high mileage used 1989 Pathfinder (3.0L, 5 speed, 180,000+ miles) in college about 20 years ago - it was a blast to drive. It developed an exhaust leak which we had planned to fix, but he got rid of it before we repaired it. He is now a sales manager at a Nissan Dealer!!
I am a retired mechanical engineer and enjoy old cars. I am currently getting my first new car road ready again. It is a 1972 AMC Ambassador, and it is the first car our kids ever rode in. I also have a 1968 AMX 390. I am a member of the AMC forum.
The purpose of joining this forum is because I found a storage tub with about a dozen parts (most NOS genuine Nissan) that we bought for my son's Pathfinder but never used. I want to give forum members first shot at them before I go to Craigslist or other outlets.
I also will enjoy reading about the adventures of forum members.
