good luck
The front bolt of the TB upper cover is lost thread, probably I tighten it too much last time I remove. How can I get it out? Any idea.

Two suggestions:

1) Use a dremel tool to cut around the upper timing belt cover to release the cover. Once cover is removed (find a used replacement), I think you can remove bolt by prying (grind a slot in a cheap chisel and bend as necessary) underneath and turning at same time.

2) Grind bolt head off to allow cover to be removed. Use vise grips to grab remaining bolt stub and pull/turn to remove. Hopefully, it's the front lower bolt and not the one near the camshaft sprocket, which will likely interfere w/ removal.

Option 2) seems less damaging. Worst case and you can't remove the bolt. Just grind head flush and install cover w/ remaining bolt.

If you can get the bolt out, you'll need to drill, retap, and install a thread insert to fully restore. Best leave this to a shop w/ experience. This is not a job to "learn".

You might check the removed bolt threads. If they are damaged, they may be the source of the problem rather than the tapped hole threads. New bolt may work OK.

good luck
