Thanks for the tips....with engine installed,, I used CRC freeze-off to get my 3VZE water temp sensor out with a 19mm Fuel line crow foot socket. I didn't break it. On that sensor is the part number from Denzo. My replacement was an exact Denso replacement with same PN. There was a copper crush washer on it. My sensor was original Denso from Toyota Japan Factory 34 yrs ago. I have only used Toyota RED coolant

Thats pretty slick brother ive had high idle on my 3vz for awhile but this will get checked today

My favorite part of this was that it free to fix. Just clean out the crusty coolant tubes going to to the throttle. Let me know if it fixes yours.

2nd video I have come across where someone had this problem and now I am quite sure that I am having the same. Thanks!

It seems like after a head gasket fails a bunch of junk moves around and blocks these tiny tubes. I hope yours cleans out as easy as mine did.

I used to have this engine. I miss it somethin' terrible.

It doesn't have the best reputation, but I feel its a decent reliable set up. I'm a Toyota fan.

Damn, I must try this as well. Big thanks, brother!

Let me know if it works

With time and patience a guy with mechanical aptitude can do it no problem. The issue everyone has who is doing they're first valve adjust is the shims. When you measure the clearance of each valve its either in spec or out of spec(.009 intake/.011 exhaust). You will have to swap a shim out of each valve that is not in spec. So for the guy who doesn't have a coffee can full of various shims this would be a terrible back and forth to the parts store to get the correct thickness shim. New shim kits are available but I wouldn't pay the asking prices I've seen. I started my various collection by salvaging shims from derelict junk heads and eventually built a nice selection of various size shims.

Thanks. Good info. I am getting ready to replace my valve cover gaskets and want to do everything I can think of while I have the intake manifold off. I was also having a warm idle at 1100-1200 rpm but solved it by replacing the O2 sensor. It dropped right down to 800. I guess the dirty O2 sensor was telling the ECU to dump too much gas into the throttle body. I am waiting to burn a full tank of gas to see if my 14 mpg has gotten any better. My temp gauge is however reading really low even when fully warmed up so I'm hoping your fix works for me. cheers.

In other trucks and 4runners i have seen aftermarket (non OEM) thermostats cause low temperatures and low MPG. If you're replacing valve cover gaskets consider doing a valve adjustment at the same time not for idle RPM but preventative maintenance.

@@bensfixitpage341 I suspect I do have a crappy aftermarket thermostat. I bought the truck new in 1990, but I just started doing my own work 2 years ago since retirement. I will be replacing it with OEM. Valve adjustment might be getting a little above my pay grade. Although I do have both factory service manuals Vol. 1 & 2 and I have recently successfully replaced the CV axles, brakes, fuel pump, cleaned the EGR and throttle body, etc. all from studying at KZread University. Is the valve adjustment pretty straightforward? I just checked and the last time the valves were adjusted was at 51K and I am now at 157K. I guess it's time. Thanks.

Will try this on my 88 pickup. Put radiator stop leak in it and have had problems ever since. Replaced the radiator, thermostat was fine and the temp gauge still doesn't work normally.

Did your temp gauge come back?

We have a water leak back here somewhere, just trying to find it........any ideas

When I get a tough to find coolant leak I like to fill then pressurize the cooing system (usually 5-15 lbs) with a coolant pressure tester tool (mine is an old snap on but Stant and others make them). There's a bypass pipe that runs underneath the intake in the valley that sometimes rust and starts peeing or the last one I chased down was a huge leak coming from the back of the drivers side head where the head gasket physically pushed out and made a a huge coolant leak.

Did you have to remove the intake to do this?

My bad I thought you were responding to a crossover delete video. Answer to your question is no the intake can stay on to ream out the little pipes

Can this be done without removing the engine ?

@bensfixitpage341

It's easy access with the upper intake runner removed. Its tricky and tight with the upper intake runner left in place (but possible). Not necessary at all to remove engine. I just used the engine on stand for the video.
