I indicated in the title I screwed up. In a rush, I lost the nut from the back of the idler pulley from the tensioner.

I can't find it. Is there any way it can get into the timing chain area of the EZ 3.0? What is the worst thing the nut can fall into?

Or do I crank the engine and cross my fingers.

Thanks

are you talking about the accessory belt tensioner? If so no, the cover is completely sealed off otherwise oil would leak.

I thought so, I just can see where it went. I can't find it anywhere.

Thanks

Also i thought the tensioners had basically welded nuts on the back of them? Its been a while since I changed the pulley bearings.

Is there enough room for it to fall between the crankshaft pulley and the timing chain cover?

From this on-line photo, it certainly looks as if that nut is free to fall down!

There's that ledge on top of the timing chain cover below the tensioner where the nut could be resting, but beyond that, if it's not anywhere around or behind the crankshaft pully, I would think it probably fell down. Does the car have an engine under cover where it might have landed?

Tore the tensioner and the alternator off. Still couldn't find it. Bizarre.

I pulled the splash shield off to see if it fell down. I saw it on the ledge mentioned before I lost it but it fell when I was trying to pick it up.

Thanks,

Probably down in some cranny below the engine where it's not going to cause a problem.

Can't use the tensioner without it, but the nut should be replaceable. If there's a fastener shop or good hardware store in your area, bring the tensioner, or just the bolt, and match it.
