Replace the knock sensor wire while you have it apart for sure. Its a short extension that runs from the harness to the knock sensor under the intake. With years of heat it gets brittle and breaks. 25bucks on EBAY.
I would start with puling the valve cover and checking valve adjustment. If that checks out ok, you can rent whats called a "noid" light at O'rielleys or probably other parts stores. It plugs into the injector plug and flashes to make sure that injector is getting a signal from the ecu. You...
Pics
The cam on the left is my old one, the right one is the new one with the missing lobe. Both are positioned the same and the #6 lobe is at the bottom, or was there anyway!!!!:mad:
Just some advice for anyone thinking about using Japan Engines for a parts supplier,,,,,, I puchased brand new heads from them for my 3vze. One of the cams was not hardened poperly and the #6 exhaust lobe wore completely flat after 150 miles of driving, sending several ouces of ground up steel...
Im going to call the supplier tomorrow and email pics to them. They are Japanese heads and were $320 ea plus a bit of shipping to get them to Alaska. I understand that these things can and do happen so I,m not mad just dissappointed because my decision to get new heads was because I wanted to...
Cam
The cam on the left is my old one, the right one is the new one with the missing lobe. Both are positioned the same and the #6 lobe is at the bottom, or was there anyway:) What interests me is the color chage @ the lobe that wore down. It looks like the new cam was never hardened??? I put...
It runs great again now atleast for now. Smooth as can be with the old cam. There was oil evreywhere under the valve cover, so I dont think it was a oiling problem. Botched hardening on the cam is what I think because there is a definate difference in the appearance of the cam on the end at...
Wow! get this! There is none, I mean none of the cam lobe for #6 exhaust there. Worn away? these are new heads! Has anyone ever seen this before? Is there something wrong with that valve/spring bucket? Im going to replace the cam with one of my old ones and check that the valve moves up and...
Thanks I will keep posting. The black is dry sooty black with no other damage to the plug. Yes a few of the connectors are cracked/broken fixed similar to yours but this one is completelt intact. tomorrow I'm pulling the valve cover and having a look, Im wondering if the exhaust shim spit out...
well I got a noid light and it looks perfect just like it should, new cap and rotor. I double checked plug and wire again. It must be something small because Ive checked everything big. I've changed fuel injectors and ecu's have compression, fuel, fire, and I'm assuming air. how could it not...
ok pulled the plenum, no cracks in intake. replaced number 6 fuel injector and still not running on number 6. there is spark + 150psi compression. i have tried different plugs and different plug wires as well as plugged in my spare ecu..... no changes. with number 6 wire hooked up there is...
Another thought,,,, when I installed the intake, I noticed it didn't sit quite level against the head surfaces. I torqued it down anyway, but I'm thinking it cracked when the motor got hot while driving. Plan to pull the plenum this morning and I bet its cracked on the port for #6.
I replaced both heads on my 89 4runner, brand new heads, all new toyota gaskets. It ran smoother that it ever had for 3 days and then began to miss,strange "popping popcorn" noise loud exhaust like noise from the air cleaner area,loss of power, and gas mileage went way down. I pulled each...
Theres just something about FJ55s, they seem so content resting in the back yard :) You have the same disease I do....... wanting to revive them and run em down the road! Great find!!! I paid 750 for both of the 55s Ive pulled out the weeds and revived:):) Its funny but the only cruiser I have...
I have been your shoes as I'm sure many of the MUD members have. I started when I was 20, Bought a 74 cj5 and totally diss-assembled it down to the frame. My dad said I was a fool for spending 1500 bucks on a truck and ruining it, then proceded to tell me that he took a lawn-mower apart once...
Ive been running the smittbilt 8000s on my trucks. They are cheap (300 ea.) and have held up well for me. I figure when one dies atleast I will have spare parts for the others. In my experience a warranty on a winch is pretty worthless, they will eventually have a issue and its damn near...
A compression check will tell you alot. Ive been on the same path as you, I pulled both heads and regroung/replaced valves honed, new rings, bearings, pistons and still burned a exhaust valve this summer. I was able to re shim it and limp for a while but now I'm ordering brand new heads from...
