So, do those sensors need to be removed for any reason, during this valve job?
...and that "knock sensor"...$70.00???
Whew!!!
Can't be fixed, eh, only replaced?

Well, the problem seems to be that it wouldn't let go.
I'll try to get a closeup photo.

This is as close as I can get and get a somewhat decent pic.

Hello, everyone.
Well, it'* been a busy, busy month.
I took the heads into O'Reilly'* on Nov.6th, for the valve job.
The following Saturday, my aunt died of a heart attack.
She lived about 200 miles away from here.
My heads were done by the 14th, so I picked them up.
The funeral was Saturday the 17th, so I didn't get them installed.
I took my mom to the funeral.
When we arrived home, that evening, my mom suffered a heart attack.
We went to the hospital, where she was admitted and spent the next week.
During the week, she suffered two more heart attacks.
The doctor asked if she wanted to stop treatment, because she is too old and weak to withstand an open-heart procedure and the amount of blockage is great.
She, and he, decided that she would to go to the hospice.
She spent five days, there, and recovered sufficiently to be brought home, where I am her primary caregiver.
I was with her the greater part of every day during her hospital/hospice stays.
She seems to be recovering, now.
About 10 days ago, my daughter told me that she would pay to have the LeSabre put back together, if I would stop worrying about it and take it to be fixed.
So far, I had spent $445.00 on the timing fix and $335.00 on the parts and valve job.
The garage owner said that he would do it for $500.00.
Day before yeaterday, he told me that O'Reilly'* put the wrong exhaust valves in both heads, and that he wasn't going to pull them off and get them sent in.
He said that he would order all new push rods, because the valve stems were too long, and that that should do it.
I called to see how it was going, and they told me that one lifter was still pumped-up and wouldn't go down, but that they'd run it until it did.
Yesterday afternoon, they called me to tell me that it had been running fine, so they took it on a five-mile test ride.
While on the test ride, the engine spun an insert.
The garage owner asked me if I could hear it in the background
If that was my car, it was knocking something awful.
When I took the car in, it had no such problem.
In fact, it has 112,000 original miles and I have receipts for everything that was done to the car since the date of original purchase, in 1986.
The oil, filters, fluids, etc., have been changed according to schedule.
...religiously!
They want to go and get a used engine and put it in.
Does anyone have any opinions on this development?
Thanks.

It sounds awfully fishy to me.
I would think that they would have some liability.
