Hi all,

I recently had to replace the o2 sensor (bank 1 sensor 1) on my '01 Tundra with 200,000 miles. After reading the forums I was scared to death that the manifold would have to be replaced also. As expected it was stuck in there, but instead of forcing it (I'm getting older), I hit it with Liquid Wrench. After 24 hours of sitting it popped right out! In fact, after I cracked it I unscrewed it w/my fingers.

I'm wondering if some these garages are going to the manifold replacement because they don't want to (or can't) wait for the penetrating oil to work.

You're probably right...these guys just want it done and done fast. If they have to sell you a manifold to boot, that's all the better.

Good job on getting this done without tearing everything up! :tu:

Another reason for the replacement is that the manifold themselves could be cracked. This is common on the early tundras. The crack is found along the seam of the flange. I've gone through two sets.

Funny thing. I attempted to replace my fuel filter. I removed the fuel relay, depressurized and such. Never replaced the filter.

Prior I had the engine light on and with my Accutron diagnostic tool I had 3 errors (fuel sensor and emissions issues).

After reinstalling the fuel relay, the engine light is off and the diagnostic tool reads no errors.

An update:

Drove 30 miles and the truck won't keep idle at low RPM's. The fuel filter is tight (possibly too tight to prohibit adequate flow), and when I come to a stop the truck just shuts off. Weird. Maybe the computer needs to readjust? Also, the enginelight came back on. I guess I need to replace the sensor. When I get home I'll check the error codes.

A couple of years back my oxygen sensor went bad and I took the Tundra in to have it replaced only to get a phone call from the service writer late in the day (who incidentally is no longer with this dealer) telling me that they had stripped the threads out of the manifold and that a new manifold was in my future at an outrageous cost ($697 total with new sensor).

I protested to the GM of the dealership and he issued me a voucher splitting the difference with me on parts and labor which I though was very generous on his part. He got my trust and respect by treating the customer right. He really is concerned about customer loyalty and satisfaction. All in all this dealer's record has been good except they keep going up on labor for routine service.

Fact is, too many mechanics are under pressure to "run em in and run 'em out" and they get in a hurry. I would have been perfectly happy leaving the truck overnight (I live about 5 miles away) just to avoid a hurried repair. As a matter of fact when the second one went south I insisted that they keep it overnight. I was reimbursed by Toyota for the second one.

IMO - In this situation, I would have protested to have the dealer cover the cost and labor of replacing the exhaust manifold not just half. It was their fault in the first place for stripping the threads not yours.
