Hey everyone!

I'm replacing my VVT Oil Control Valves on my 2007 SR5. I have a few questions.

I can't justify paying the dealership $700 to replace these simple valves, so I got the Toyota part numbers and I will be doing it myself:

RH - TO 15330-0P010
LH - TO 15340-0P010

If I buy these OCV's from somewhere other than Toyota, what is a reputable replacement brand? I searched around for replacements and there are several brands ranging in price from $50 to $79 (ish). Toyota parts are $165 or so each. Normally I would buy factory Toyota parts, but if the aftermarkets are comparable, I would like to hear about it. That's a huge difference in price.

Also, it appears there is a part number for a filter. Do the OCV's come with this filter typically or is this a separate in-line filter of some kind? If I get this too, Toyota or is after-market acceptable?

And last, I would probably know the answer to the above question if I could find a good document that covers how to replace these. I have the factory service manual that shows the procedure for testing them, but not the actual replacement of the OCV's.

If there is a post on this somewhere, I apologize, but wasn't finding much.

Any help would be appreciated!

Thanks everyone!
Scott
