99 Camshaft timing tube leak
For some reason i cant login on the forum with my two laptops, but i can on the desktop. Okay well it has been a long week for me, sometime back i had a leak and i thought it was cam seal. So, i replace the cam seal with a new timing belt, after a month the car was still leaking so i replace the cam seal again and the leak keep getting worse. Last week i decided to chase down that leak, what i did was take everthing out, clean and the put back except for the timing cover. Then i start the car and looking for a leak. Guess what, the camshaft timing tubes a leaking like crazy i didnt believe it. This means i have to buy new one because the repair manual say to never take out the four torx bolt. Did anybody ever experience this?

maybe this will help:
As you may be well aware of, the camshafts need to be removed on this engine to replace the cam seals. If this was not a Lexus trained/experienced technician and all bolts for the camshafts are properly installed and nothing is out of place then most likely what happened here is your mechanic touched a bolt on the vvt-i controller that he was not supposed to. When you remove the camshafts on this car instead of just having a timing belt pulley conected to the camshaft there is a vvt-i controller that incorporates the pulley, the removal and installation procedure for this is very specific and can be VERY confusting if you are not familiar with it. If the vvt-i head was tampered with there is no correcting it, it has to be replaced.
this was copied from another post, I have no knowledge of how to do this, for me, it is just a warning..

I am familiar with what need to be done, i just never thought the camshaft timing will ever leak. The seal are okay(dry) but either way i have to take everything out. I have seen few questions about 1998-2000 cam seal, i will take picture and write a tutorial when i get the parts i ordered.

I just receive the new camshaft timing tube today. If you eve have to order this make sure to match the color. For a reason they are two types of this tube, one with red mark and other with green. Specification for this two units are different so make sure to check your car before you order. I will find out more about this, or someone in the forum can explain
I also run in to few things i need to take care of; spark plug tube gasket are dry like a rock(they came apart) and most of the vacuum piping. So i made a second order of parts just to make sure i replace anything that is not right. Does anybody know if Toyota sell the ignition coil connector?, i am sure dont want to buy new wire.
