Thanks, I did post it. Some info though. I have a cousin who has 3 SHO's and has performed a lot of work on his own. We took my tensioner assembly and compared it with another known good one. The diference is amazing. The plunger from my 94 181K couls be pushed in with a bit of effort. The good one was very difficult to push in. We disassembled the "bad" one and put in some oil then reassembled...The results were the same as the known good one. So, I suppose that most/soem of the oil must have leaked out over the years. We're (not were) going to experiment with the amount of oil and try and locate a replacement seal which sits under the c-clip. I'll finish assembling the engine tomorrow and make certain that the noise is gone. Where do you live in Michigan? I retired from Ford in '07 and made many, many trips there...know Dearborn like my hometown..thanks again...Jim
