Good questions Swedecar...you're right I wasn't very clear, I'll try to explain better.
>This is the top bolt for the spring loaded/oil filled tensioner that >first goes through a curved sheet metal bracket and in through the >
>tensioner piston, right?
CORRECT
>And you say that the first inch of threads in the timing cover is fine, >right?
>How do you know that the threads further in, in the timing cover is bad? >And why do you want to run the bolt further in through the timing cover >than 1".
This top tensioner bolt would hand turn in the 1st inch and then require a wrench, then it turned fairly easily but stiffly ending with a lot of tension (greater than the torque spec. of 15 lb-ft) before the head contacted the bracket or tensioner bushing. This is a long bolt, approx. 3 or 3.5 inches....right?
>Have you broken the original bolt and found a new longer one?
Nope, using same bolt that came out.
>If the timing cover have threads, that means that the bolt doesn't go >through the cover and into the engine block. It wouldn't work with having >threaded hole on both items.
I may be wrong and may only thread into the timing cover...but it is such a long bolt I thought it might go into the block.
>On the 93 and older engines it was actually a loose bracket bolted onto >the engine that top bolt was bolted on to.
Kinda wish I had that setup on my 1997.
>So the way I see it you only need to find a little bit shorter bolt and >get rid of the extra washers.
This is what I did with the orig bolt, requiring about 4 thick washers, but now looking down on the bolt, after installation, it looks slightly off from perpendicular to the hole :-(. Therefore am wondering if this will last and not strand me.
>If the threads in the timing cover would be stripped all the way out I >would buy a kit called Timesert for 8mm holes and repair the hole using >those repair sleeves. That kit is much better and easier to use than >Helicoil
I'm thinking the deepest 2 inches or so of threads are bad...where do I buy the Timesert? Aluminum is delicate eh?
Thank you for you time Swedecar!
