**Disclaimer: This is my first dealing with a timing chain and I only need three more weeks out of this engine. (I leave in three weeks and come back this summer, hopefully a rebuild at that time.)

I needed to do the job this weekend, or not at all. So I was limited to the parts that were available locally. Got a full camshaft set and three piece BS elimination set. Opted to not replace the oil pump as pressure was around 60.

No real issues installing, oil pump looked good. All the old guides were worn to metal, teeth on the oil pump sprocket were considerably worn. I replaced it with the one that had been on the upper balance shaft. The BS elimination set did not come with any guides, chain was tight so I didn't think to install the old one. Is this a major mistake?

Engine runs OK, made it to work today. There is a high pitched sound that wasn't there before this issue started. It increases/decreases with rpm increase/decrease Is it the timing chain rubbing against the new guides? It doesn't bother me other than if it's a sign that I need to fix/refix something.
