You're welcome. Glad to help. Just keep in mind that anytime you have an SES light to get the codes first (which you did) and then refer to BC to get info if you are unsure. It is always fun to help others out, and to know the knowledge gets passed on.

Good luck, and make sure you come back.

This forum is great, I'll be back for sure.

I'm so happy about all the money I saved. I spent about $65 for the O2 and Cam senser and a few tools. And the labor was free!!

My next project will be the brakes. I ordered a repair manual off ebay. I should receive it in a few days.

thanks again.

Chilttons or a factory service manual? Chiltons might be OK for stuff like brakes but the best kind of manuals are those printed for GM.

We've got several tutorials and Wiki'* over at www.lesabret.com specifically for 87-91 era H-body cars as that was the only era that T Types were made. Wouldn't hurt to browse over there once in a while if ya want

Heres a couple threads you might find of interest for brakes:

Front Brake tutorial: http://www.lesabret.com/phpBB/viewtopic.php?t=2494

Rear Brake Tutorial: http://www.lesabret.com/phpBB/viewtopic.php?t=4060

Oh, if lesabret doesn't load its because our server has had some issues the last couple days. The host is working on getting it fixed though.

Default Camshaft Interrupter Magnet

Glad your situation is fixed! Great job! In the one I did today, the magnet appeared to be intact on the sprocket. However, something didn't look quite right. The plastic housing that holds the magnet was packed with sludge and parts of the plastic housing were gone. I used a dental-like pick and probed it. The plastic top fell away and revealed a much smaller magnet encased in sludge. I pulled it out with needle nose pliers and it was about 1/8" cubed in size, about 2.5 times as small as a new one. I am not sure how a magnet could remain in the plastic housing, yet shrink to less than half it'* original size. Apparently the now smaller "eroded" magnet was not strong enough to trip the sensor. Also, a new magnet is shiny like chrome. This was dull and black. I picked and pulled all the old brittle plastic out, cleaned the complete area with a rag and then acetone and Q-tips. I inserted a new magnet using the same method outlined in Padgett'* method. Worked great. I believe you were really fortunate and the camshaft sensor really was the issue, however, if you get Code 41 again in the near future, consider the magnet, even if it "looks" like it is there. In this case, perhaps the new sensor you installed was more sensitive and was able to pick up the now smaller, weaker magnet'* signal. If this happens (hopefully not), replace the magnet and never look back.

gsantander,
thanks for the info. Its strange how the magnet just erodes away.
I'll keep this in mind in case code 41 rears it ugly head again.
In the mean time, the car is keeping me busy with other stuff.
I just replaced the water pump. Also, I have to fix the front power
windows. It will be a hot summer if I don't!
thanks,
jasper
