Another update:

Previa still running strong at 50K miles after head gasket replacement. Finally retired it as daily driver but use it when hauling is needed.

Just an update

The Previa is still going strong 23,000 miles after the head gasket replacement. I have a new job that requires travel mostly around the east coast and been using the previa for...

I only bent a couple of the tabs when putting in the Anco blades. I think one issue is that the original Toyota metal stiffening strip is curved and the Anco plastic is straight. I had to fineness...

I bought these about 4 years ago but did not find them until after I put the Anco's on. Guess I'll keep them until the Previa is ready for a concourse.

I installed a set of ANCO W-28R's a few months ago. They work well on my 1993. I had to use needle nose pliers to straighten some of the metal tabs that got bent over the years so that I could...

It looks like they will...

I was able to see a picture that is not showing by doing a google search on the link.

Drove the van on a trip about 1800 miles of highway driving and it is still running well. Have about 4000 miles with the new head gasket. Van has lost no oil or water.

I have a set of ANCO W-28R but have not tried them yet. It looks like they would replace the metal stiffener with the plastic included with the new inset. Let us know if the Ancos work. Thanks.

My original muffler lasted 18 years and I'm on after market muffler number 3 since then. I did not have the whistle problem but the drain pipe looks like a good place to investigate. I wish the...

I went to School in the U.P. of Michigan and am familiar with that stuff. It also sunk the Edmond Fitzgerald.

I found the cause of my noise. It was a black walnut and probably a squirrel.

I need to replace the bushings anyways, so I will take the shaft out and inspect the bearing. I am hoping I can find a way to get some grease into it and it will last for a while.

The bushings...

I have an off and on squeaking noise that seems to be coming from the front SADS bearing. The sound is like a dry bearing. I thought it might be the alternator, PS pump, or AC compressor but used a...

I have driven the Previa about 1200 miles since replacing the head gasket and it is running fine. It seems to have a bit more power than before and the gas mileage has increased a bit as well. It...

I finished getting everything together and the engine is running well after a few minutes of smoke from the antifreeze in the exhaust and the oil I used while assembling the head. I ran the engine...

Thanks. The TSB made me feel better about it too.

Some additional information that may be helpful:
I drained the oil the day after the gasket blew and there was quite a bit of water in the oil...

I put on the gasket....

Will work on connecting all the peripherals and getting the job finished as time permits.

Cleaned up the block deck and it is in good shape other then the pitted area.

After reading about possible options, I decided to use a small bit of JB Weld epoxy in the pitted area.It takes...

Although I want to minimize the work on this job, I decided I better at least replace the valve seals since I have the head off and there are so many miles on the engine. I'm glad I decided to do...

Thanks for the information timsrv. I don't really want to coat the whole head gasket just to address the small pitted area. I may use a small amount of the Permatex or something similar just in the...

Any suggestions about how to handle the engine block pitting?

The new head gasket uses a metal frame around the water passages. Hopefully, this is a design improvement.

I removed the exhaust manifold using hammer, chisel, and heat to get the last stud out.

Removing the oil filter mount was useful as it allowed me to lower the engine quite a bit. I...

I started working on replacing my head gasket today using the leave the engine in the van technique. Here are some pictures of today's progress.

I had a similar issue with my 93 NA Previa. Have you checked the Air Flow Meter? The service manual has a test procedure that you can use an ohm meter to go through. It could also just be a poor...

Decided to try and repair the engine rather than sell the Previa
