Smog vacuume manifold for fj40 I think 1976 vintage. $40 plus ride

So I received bought a 95 4.5L and it had the typical mpg, this thing drank gas. Anyways I go to get it smogged and it passes everything but the egr test. Smog guy said it wasn’t holding vacuum, so I replace it and it failed again. He was a bro and passed it, but said to comeback when I fix it...

Was working through some issues on my FJ62 today, mainly a hard start issue, but was checking everything over. Ended up realizing I had a vacuum line that was pulled when I desmogged my FJ62 a few years ago and was causing the EVAP system not to function correctly. Anyways while troubleshooting...

I was swapping my old vacuum lines for fresh and snapped one of the plastic nipples off what I think is my HACV, high altitude compensator valve. I checked on mega zip to Id it, pretty sure it's th HACV, and it shows discontinued. US there a later valve I can replace it with?or am I down to...

Came off a 71 I parted, I think these are 71 only? firewall tube and I think the other is one of the tubes that go under the floor pan. The other was most likely too far gone. These two are in good shape. $20 plus the ride. Probably $30ish to ship.

wanted to consult the experts on something that has me stumped. executive summary - I accidentally shifted my '68 into FWD, and then couldn't get it back to 2WD. tested vacuum lines and they are working. replaced them anyway with new just in case. it certainly appears as the vacuum shifter on...

I took my 95 LC 4.5L to get smogged, it passed every thing, but the EGR valve wont hold a vacuum. I replaced the valve and still it wont hold a vacuum, so I am getting a replacement. Is he doing the test correctly? its in idle when he attempts. if i remember correctly my 88 4runner had a...

I've seen a few posts regarding the 're-tubing' of everyone's matrix of vacuum hoses under their respective hoods. It seems daunting, but I think between JimC's de-smogged guide, mine is now, and a few other diagrams out here, I can work my way through the process. McMaster-Carr seems to have...

Hi all, Trying to tune the 60 but its proving difficult doing the lean drop with this aftermarket chinese carb I'm running with. Using a line from the intake I get 12 mercury, but i know the ideal range is 15-20. will this increase as I get closer in tuning this, or do I have vacuum leak? Im...

I have a 1974 FJ40 that I need help with on how to run the vacuum lines based on my setup. I have an earlier emissions control device )which I would like to utilize it since I just recently bought one from BTB products) an 75 stock carb, I believe a 78 distributor, and a 2f motor with an 2f...

Back for some help. I purchased a new 24v Alternator (Dynamo) from CruiserWorld a couple of months back. From day one I lost brake boost at idle but a slight press on the go pedal and all was good. (I could stop) I was just on my way back from a 3200 KLM trip and 1000K from home when the...

Hi all, Wanted some advice on what the best possible fix for a rusted vacuum connection that broke would be? The vacuum line can't connect anymore because the nipple portion has rusted and broken off. Any ideas?

Hey All, I'm tracking down a P401 insufficient EGR issue. I've followed the FSM to check for vacuum at the EGR valve during cold/warmed up at 2500 rpm as well as moving the vacuum line from the modulator to the vacuum circuit. I did not see vacuum at the EGR valve in any of those conditions. The...

Hello can anyone help me a this, I redid my injectors on a 96 4Runner 3.4 and when I put plenums and all hoses on I saw this port on the back of the bottom plenum there was no hose and all hoses appear hooked up. I will attach pic of port and port location. It has vacuum suction when engine is...

I have read most of the forums on here. But none of them touch on what I’m dealing with. I own a 1995 Land Cruiser (with OBDII) If you look at the attached image, you’ll see my color coding trying to solve the issue. Green means I have tested it, and/or replaced it. Red means I’m getting no...

Hello all I have a 98 that I purchased in February in Texas. There was an issue that led me to replace the master cylinder assembly. All has been fine with brakes until recently. A slight leak coming from rebuilt assembly - which was fixed meanwhile my mechanic tells me that MBCA is fine and I...

Hi all! Just wanted to share my solution when getting weak vacuum recovery on multiple brake applications. Especially when upgraded to a dual diaphragm brake booster. The solution is based on a standard vacuum pump and is using both vacuum chambers in the reservoir tank. It keeps the low...

Hi Guys, newbie here. Been happy using my Uview 550000 Airlift vacuum/purge tool. Worked great on my 2003 Honda Gold Wing. Have you purged your coolant system with this tool on your LC 100? Now I'm trying to use it on my 2000 LC. I was checking my fluids and noticed my coolant reservoir...

Hey all, I recently took on the job of rebuilding the carb on my FJ60, and got all the way to the vacuum passage bolt only to realize, it was just a tiny bit stuck, and eventually I managed to strip it to the point that a screw extractor was necessary, which completely mangled the bolt. Now I'm...

Just wanted to put it out on the forum, I reproduce a lot of the engine bay and cab decals for the 4runners and pickups. Check out my website and hit me up if you need any redone. Simply need a good pic and dimensions. Mostly 79-95 years but slowly getting more done. I can only post 5 pics...
