I don't have anything to offer but have read this full post and there are a lot of interesting learnings in it. I'm sorry you are having the trouble but reading this is a good learning experience...

Thanks for your reply Tan Van,

I'm not going to buy Moog parts anymore. I always thought they were good.

I have been buying closeout items from Rock Auto just like you just to have around...

Hi John,

You may not still be around but I just wanted to comment on Moog lasting the least for your tie rod ends. I replaced my first set of inner tie rod ends on my van after 380000 miles. I...

Wow... How nice is this thread that you found. This is just what I needed to know. It is so good to see what is in there so you can understand how it works and what needs to be changed.

Thanks...

If you try it, just remember that you are not supposed to let the back of the shaft drop or move sideways much at all because if you do, you risk damaging the front coupling. You will have to...

Thanks again for your help pdgizwiz. I think I finally understand the whole distributor issue and it's good for me that I understand now. I feel better about it all. Since I have changed the...

Thanks again PDGIZWIZ... The picture you posted with the distributor on top of the picture and the distributor gear with the hand on it on the bottom of the picture just posted real good and I can...

Thank you PDGIZWIZ for the two diagrams from the FSM. I have never known about the shaft O Ring but I'm sure this is what is wrong with my car. This is so good to know because I've been trying to...

My leak condition is exactly the same as you describe for yours. I've always thought there must be some kind of seal on the distributor shaft. I just saw PDGIZWIZ post with the FSM drawings showing...

I'm sorry to be so late with this reply. I have seen this happen on small engines that have carburetors and the problem is always with the fuel adjustment. Sometimes you have to adjust the...

I just used advanced search to find your 2015 post on the tray modification. Very nice job. I wonder why Toyota made the tray drip on the exhaust header. They must have had a reason.

You could...

Thanks tbkilb01,

I just learned how to use the advanced search a couple of weeks ago. If you look at the tag list, it will show you the words to put into the advanced search. I'll find the...

Hi TBkilb01, It took me a minute but I finally can see the modification you made to the drip tray. How did you connect the tube to the tray so the oil will drip down the tube you installed? That's...

Thanks Previologist. I'll drive for a couple of weeks and check the tray for oil. I cleaned it real good when I changed my valve cover gasket. I hope changing the valve cover gasket will stop oil...

I'll check out the distributor real good when I pull it. There must be some kind of seal or bushing or something between the distributor rotating part and the distributor case. I'll look..

Thanks for your note. I did replace the valve cover gasket just this week and it is not leaking any now. But oil is still getting on that little plate below the distributor. I'm not sure of this...

I replaced the "O" ring under my distributor and I'm still getting a leak of oil from that area. Is there another place oil can come out of the distributor? Or did I just put the "O" ring in...

I have a Previa. Has anyone installed a filter on the coolant to keep it clean? Like the coolant filters diesel engines sometimes have.

I just looked at this website and it has great parts diagrams. Very nice to have this information. I've saved this to my favorites.

THANKS...

I learned that the ToyoDIY.com side does not have parts diagrams anymore because of a complaint from Toyota. So I Googled parts diagrams for a 1991 Toyota Previa and the diagram that John posted...

Thanks John. This looks right and the picture is very helpful. Now I can tell what I am getting into.

I didn't know about ToyoDIY.com. It's a great site and I'll save it in my favorites.... ...

Does anyone know the part number or part description for the gasket that goes between the head and the oil return pipe. This is the pipe that drains the valve cover area back to the oil pan located...

I just unplugged the pump that is located on the bottom of the oil reservoir under the hood. It is bad to overfill an engine with oil. I unplugged mine over 20 years ago and all has been great...

Thanks Man_btc... I appreciate your reply and now won't worry so much. I also just read a thread about checking valve clearances and my need to do that since I have never checked them and have 400K...

I have a 1991 Toyota Previa. Is there a hose of death or other "disaster looming" issue on a Previa like this Hose of Death?

I've read this thread because it was very interesting and I like...

Hi Lawrenco. I'm sorry they didn't work for your van and I realized after I shipped them that they probably would not because your van has a low beam head light and a separate high beam headlight. ...

Hi Lawrenceco

I shipped the LED headlights to someone on this forum last month.

Sam

I think it is right that this upgrade will still work without the sleeves. The only thing these couplings do is make the shaft rotate. The shaft is held in place by the bearings on each that are...

I replaced the SADS couplers on my 1991 Previa (396000 miles) yesterday and used the Fibi BMW couplers from Pelican parts, part number 26-11-1-225-624. The cost for these couplers was $95.00...

I used the Harbor Freight tool and it worked perfect. I was very satisfied with the tool. First time I've ever changed inner tie rod ends too.

I'm going to try the BMW couplers out. If they don't work out, I can always go back to Febest. Both are less expensive now than when I bought the Febest before. Only regret will be the time to do...

The LED's I have aren't too bright for on-coming cars. I had my wife drive toward me at night when I had the bulbs on low beam and then on high beam. She said even on high beam there wasn't an...

Totally agree with you Rainbow Bridge about communications and talking together. You can figure out a lot of things if you are able to talk things out a little.

On my post above, I noticed a typo...

I changed 2 valve cover gaskets and then did a post check and the real problem, at least on mine, is the valve cover gasket bolts bottom out before the gasket crush is good enough to seal the gasket....

I bought some LED headlights for about $100 and tried them and don't like them because they don't have a good high beam. Low beam is great but not much difference when you go to high beam. So I...

I polished my headlights and then bought Hella bulbs from Rock Auto for less than $2.00 each. Then I aligned my headlights and now they are great. I'll bet the problem most people are having with...

Thanks for your help Previologist,

I'm going to try these new couplers and I'll let you know what I find out. They must work because a lot of people have used them and after getting the bolts...

Thanks Previologist,

Do you remember if there was an installing issue with the different inner bushing stick out pattern of the BMW versus the Toyota style? I'm trying to understand before I buy....

Thanks John,

I try to minimize the use of my AC too and I think that is why this last set of my couplers has lasted as long. I will find out the answer to this question when I install these new...

Hello John and All,

I have looked at the BMW coupler and one thing that is different than the Toyota original is that the 6 metal sleeves on the BMW part all stick out the same amount on each side...

Thanks for this information John. I'm going to use the BMW parts on this upcoming change. I want something better and these certainly seem much more heavy duty and these guys had very good results...

Hello John,

I forgot to say thank you for the link to the BMW part.

Sam

Thank you for your reply John.

I think I can still get the Genuine Toyota couplings for a '94 to '97 but as far as I can tell, Toyota doesn't provide replacement couplings for '91 to '93 year...

I am new to this forum so I'm sorry if I'm asking a question that has been answered a thousand times. I've read this thread on the SADS couplings. It is extremely interesting to me because I have...
