Well...the plot thickens. ... so the Dorman balancer is the Dayco Part?
The balancer pictured is the original, to the car WHEN WE PURCHASED it. it has been removed twice. When i first got the car from my brother I was told a new CKP sensor was installed. I did some research and found posts about the balancer being an issue. When everything checked out, I went to order a Dorman. After removing the pictured, original to car, balancer the bolt holes got damaged. Saturday the car was running and I figured why not replace it now. Now the car does not start. The pictured balancer is original to car when we bought it. Google search the pictured balancer # and it comes up with a Dayco powerband balancer. Looks in great shape. Now the car currently has the Dorman and does not run. Thinking I should remove the Dorman. install new CKP sensor and original Dayco and see what happens?Not just metal - there are two main steel parts, thick rings, inner/outer, joined by a layer of vulcanized rubber. Dorman has a reputation for being lowest quality - rubber not lasting I think is #1, #2 is bolts not holding up.
Some parts aren't worth the risk when it's a car you want to keep and depend on, but you said just to get a couple months out of it, so...
Otherwise, I think the question is how much risk an owner is willing to take with a suspected lower quality HB. It might be ok for a while, but a fail can be costly if it takes out other components, making it no bargain in the end.
How many times has the one in the photo been installed? Remind us why you removed it?
If you're certain the one installed now isn't chewing at the CKP sensor, then leave it and watch it like a hawk. If the one in the photo isn't that old (not sure why you refer to it as 'stock/original'?), and hasn't been repeatedly swapped out, then consider re-using it. If you don't want to face risk at all, get the Dayco or BHJ. Just my $0.02 USD.
