Yep, PCV installed and operational (I think). The leak only occurred with the engine running at operational temps and it was more of a seepage than a full-on leak. There is no oil slinger on this engine, when you look into the hole in the timing cover, with the seal removed, you can see the lower end of the timing chain. I think that after I get this engine reassembled that I will take a look at the pressure in the crankcase just to see if the PCV is doing its job.

I didn't realize this was on your truck. That's a pretty pricey system!

Well Ross, I looked at this spring some more and tried inserting one end of the spring (tapered end) into the other end and giving it a turn. I was able to turn it two revolutions until the ends came together in what appeared to be a seamless joint. Now I can't get them apart...not that this is a bad thing...but it does tell me that someone in Mexico did not do a good job at the manufacturing facility where this spring was fabricated. I replaced the seal with one made by Timken, we'll see if Taiwan did a better job on this seal.

I didn't want to say it earlier, but I was assuming Timken's would be Hecho en Chine. Taiwan stuff is usually a cut above Chinese, and let's face it, this isn't rocket science. Just glad you caught it early!
