Wow, you really are da man! Thanks for sharing.
I have never heard of motor oil being used in a manual transmission. Never thought I’d hear that it didn’t lead to a colossal failure. I wonder how long this would prolong your transmission.
It does indeed sound like an EGR problem. EGR is supposed to suck up exhaust fumes from the exhaust and redirect it to the intake. Of course this also sucks in carbon, and once mixed with oil from...
So there's no vibration at idle? Lack of power could be because of fuel delivery, air restriction, or ignition issues, assuming your transmission is ok. Your supercharger also may not be engaging,...
I do. It isn't too clear on handling the transmission mounts. The mounts in a manual are U-shaped,and won't clear the frame without lowering the transmission, and I don't want to do that while the...
Hello eggxperts. I did the biggest job of my life last winter and replaced the old Previa engine with a JDM unit. Engine works great, no problems, except for one nagging mistake. Clutch shudder. The...
Cool! The crane-through-the-door method is how I did it also! I hope my post on here actually helped you! I like this method because it does not require any additional equipment on top of a crane,...
Yeah, not only that. The ticking has resolved itself. No more ticking at all. Fuel injectors have been sitting for 20 years. Just had to be freed up!
Hey guys. I found out what the noise is. It's not the lifters. I measured every one. They are all in spec.
The noise is a ticking fuel injector. I realized the ticking stops whenever I let go of...
Hey guys, my JDM is running and performing well? Is this valve tappet sound, or exhaust leak? I know I have an exhaust leak, but I don't know if that is causing the noise or not.
...
I may have misspoke. I didn't meant detach the bearing with the coupler, but just the forward bearing. The forward bearing has to be separable from the front coupler, otherwise, why isn't it included...
BTW, my method for installing the engine was pushing a crane through the passenger door.

Like others, I also used straps to support the thing, while I pushed it into position.
I just turned on my JDM engine, and it's working great! Smooth as a baby's bottom. Here's another positive experience for JDM engines. It seems that the Japanese took really good care of these old...
Hello Previa experts.
I am stumped. I am in the middle of trying to replace my Previa SAD shaft (along with a JDM engine). I purchased a used 95 SAD shaft to upgrade my 91 because I have read...
Is the Toyota Previa's shifter supposed to return to the center when moved between 1st and 2nd? It does when shifted between 5th and reverse. There's a spring in the shifter housing that returns the...
When I received the engine, it had the hoses and wires cut just like every other JDM engine I have seen. I guess I find the odds of it not being a JDM engine unlikely. I mean, the vast majority of...
Hey everyone, I am starting to get suspicious and worried that my JDM engine is not actually a JDM. I have noticed differences from other JDM images on Ebay. My engine's differences:
The fuel...
I am in the midst of swapping a JDM engine into a Previa. I am wondering if I can quickly test the JDM engine without attaching the SAD. I want to know if the engine was installed properly, and is...
Good to know. My intake is in peices now, so I might take a look at that when I put it back together. This has opportunity for creative substitute.
My problem is lack of self confidence and experience. I have never rebuilt an engine. I am afraid that there is so much opportunity for me to mess up. I am somewhat tempted to go in deeper. I...
I searched through my factory service manual, and couldn't find any mention of that sensor either. It is connected to the the oil cooling lines, but what it is, I cannot say.
That there is the knock sensor.
Thanks for the response. So you're telling me you haven't had any troubles with the JDM engines. I intend to keep mine for many more years, but only use it strictly for road trips and load hauling....
No borescope. Brainy caps?
Hey Pdgizwiz,
But what about a JDM engine? I recently purchased a JDM engine to replace the old neglected engine. The PO of my Previa put straight water in the engine, causing rust galore, so...
Hey everyone.
I am working on replacing my 1991 Toyota Previa Engine with a JDM replacement. Before buying, I asked the seller for pictures of the inside of the engine. At first, it looked...
Hey! I am about to swap out my engine and transmission also! Where did you connect the straps to on the van? How did you lower the transmission? This would help me tremendously!
Hey Tim. I'm getting ready to swap my engine out also. My question is, what did you wrap the straps around on the Previa? The frame rails are not an option since they are coated with rubberized...
Interesting that would be a problem. Are our struts gas or oil filled? When I drove mine in sub freezing temperatures, it squeeked and rattled, but it still moved up and down. Doesnt makes sense, if...
I just spent $700 on Toyota Previa parts myself. I am going to replace the old engine with a JDM. I will take pictures and report here in a month or two. I plan to begin the project after New Years.
Looks good! Those from an Estima? Did you have to drill and cut to get them to fit? Please enlighten us.
Hey all,
I've had my Previa for almost 3 years now. Mine is a 1991 5 Speed. I like the van and all the utility it brings, but I think the head gasket could be about to go. The coolant reservoir...
Take it to a shop that has a gas analyzer. You want to know for certain if it is a headgasket.
Went to mechanic. Found the problem! 4189
Hey Previa Gang.
I am stumped with this one. Here's what happened.
Very quickly, my van developed a vibration at 45+ MPH. It's a manual transmission 1991 model, 2WD. It doesn't feel like...
I might be interested in buying it. My question though is whether or not you need to drill to attach the 2". All the aftermarket on ebay claim the need to drill. I would prefer not to do that. What...
Nice. Thanks for the write up. Why exactly does the heater core need to be replaced? Why would the heater core itself need to be replaced? Isn't it just a solid piece of metal? Is it the interface...
That's interesting to see. You mind taken some extra pictures of reassembly and the finished project? Your extra experience assembling the wildly inconvenient previa would be nice to add to the...
Good to hear doing this job isn't hopeless without persistence. I plan to upgrade my 12mm to 14mm in the coming years. I am worried about messing it up, but if I do, it's nice to know try try again...
I am not sure of the shaft is interchangeable, but are you sure you didn't install it backwards? The thick side towards the engine and the thin side toward the accessories. When you reinstall it,...
Maybe try video taping the noise and posting it here via youtube. That would help us help you tremondously. I am still leaning torwards accessory belts.
What about O2 sensors? When those things go bad, your fuel delivery is all messed up, since they control idle fuel delivery and such. I wonder if your obd2 scanner to check for O2 live data. I doubt...
Keep us posted if the issue returns. Interesting how the darnedest things can fix a car. Maybe with time this odd fix will not prove to be the root problem. Or maybe it will.
Try putting in some HEET starter fluid in the van. It is meant to help with freezing and moisture, but it solved my camry's cold start issues, similar to yours. I don know why it did, but give it a...
Of all things, the toyota previa's water pump is the one part that's easier to replace than on most other cars. Most cars require messing with the timing belt to remove the water pump, but not the...
Thanks for sharing. Where did you get the bushings? Did you buy oem couplers from toyota? Aftermarket couplers? Poyuerathane? How long ago did you do the repair? These data points would be helpful.
Wow. How on earth did you figure that one out? I would have never guessed that one.
Before you throw money at parts, go ahead and save yourself from risk by inspecting the bushings yourself. Get underneath the van and look at the SADs shaft ends. It will be pretty obvious if your...
What made you decide to adjust the valves? I have never done it, and wonder why it's necessary. I know FSM mandates it, but I don't know why. Decreased performance ? Bent valves? I am not so sure.
Why not try ebay? There are tons of them on eBay for cheap. Buff em out, polish, and bam, they're like new. In fact eBay is where I get most car parts for older cars. I got my 95 SAD shaft there for...
