Idle Arms and Timing chain Housing questions
Hello,
There are two things that are concerning me with my rebuild. The nuts that are used on the inside of the timing chain housings that hold them to the motor, and idler arm movement on the shaft in the housing.
- First thing, the nuts. My book calls for "vibration resistant egg-shaped locking 13mm nuts" to be used on the inside of the timing chain housings. I didn't have any, so I went to my local performance Porsche shop and spoke to the neighborhood guru to try to get the right nuts. He says he just uses regular 13mm nuts and handed me some. Will this be okay?
- Second thing, idler arms. The book says to just install them by putting a few drops of oil on the shaft and sliding them on. I noticed that with the tensioners installed, I can still move them forward and backwards on the shaft (pull them in and out). Are they supposed to have a small range of motion?
I have the upgraded oil fed tensioners and upgraded idler arms.
