Most of the threads you post in have replies with concerns about tone, excessive sarcasm, or other issues with your attitude. Like a wise man once told me, "If people think your an asshole, then you are an asshole." Just something to think about.

Re: Too much timing belt travel...
one thing to try would be to put a mark on the belt and driver side cam pulley on the place where the belt runs out towards the front of the car. run the car and watch the marks if it consistently lines up the marks when the belt moves towards the end of the sprocket then it's the belt. if the marks don't line up when the belt moves then it's not. since the marked part of the belt will not be in the same place in relation to the timing marks every time it goes around then it will establish whether the consistency is in relation to something on the engine or the belt itself. if it happens when the cam is in a certain position but not when the belt is then it would most likely be an engine problem. i vote for buying another belt, they have steel or nylon belts in them like a tire, if a few of them get broken or rolled over then only the rubber is holding the belt together at a certain point which allows it to stretch under tension.

If it was a rotational component, the belt runout would happen at a different position on the belt with each rotation. But since the movement is at the same point on the belt (with respect to the belt markings) I think it must be the belt. |

Re: Too much timing belt travel...
Funny as this sounds I was listening to the rhythm it was always the same .components move at different speeds the belt is at the same speed .think of it as a bad link in a bicycle chain it would always clunk in the same spot even though the sprockets go around 4 or 5 times to a chain REV. Hence the clunk or in this case the drift is always the same..

Re: Too much timing belt travel...
Thank you, icingdeath88
I have spent a lifetime trying to treat people nicer than they treat me. That has always been my passion but I did have some reservations about that one! I have been running up and down the freeway ever since I posted it and have been feeling bad... wondering if I would be home in time to edit it. Your reply is certainly encouraging so maybe my niceness record still remains intact. I certainly hope it will be accepted by everyone in the same spirit it was sent! Now my spirit has been lifted! Thanks again for the nice post. I owe you one, man! Take care, Keith |

Re: Too much timing belt travel...
I am relieved to say that after over two weeks and 105 posts, the problem has been solved!
The culprit being a defective timing belt. I picked up the new OEM belt from subaru earlier today. Upon inspection and comparison the new belt and previous belt (PCI) looked essentially the same. The markings on the new belt from Subaru however were much more helpful. There was a dotted line across the belt which related to alignment with the crankshaft sprocket and timing marks, whereas the other two marks were solid lines for the right and left bank camshaft sprockets. Simple and easy no guess work involved. I did notice that there was more slack on the new belt as opposed to the old. This was confirmed when I removed the allen wrench from the hydraulic tensioner, the piston extended sigificantly more than with the previous belt. Perhaps I had the wrong belt all along...I'll never know I guess. I know others have used PCI for the timing belt kit and have installed without any problems. But like any mass produced product I unfortunately came upon a defective unit in the bunch. Thanks again for everyone's help, I am greatly apprectiative. Hopefully my misfortune and the responding posts will benefit others in the future. http://youtu.be/rHGZzcjjF2I |
