Lifter Retainer Ring?
I don't know if that's the correct name for it, but you can see in one picture it has fallen to the bottom, and in another I'm holding it part way up with my finger. What are the consequences of this and how expensive is it to repair?

Re: Lifter Retainer Ring?
Oh my that needs attention. needs to be replaced. Those are the stock oil deflecters. I dare say you have metal shavings floating about.

Re: Lifter Retainer Ring?
How hard is it to replace? Or could I just go with something like this since I have tall valve covers?

Re: Lifter Retainer Ring?
Are my eyes playing tricks on me or are there two different versions of retainers here, look at the springs to either side of the failed one....
What engine is this we are looking at?

Re: Lifter Retainer Ring?
On the exhaust valve spring the retainers have rotators that turn the valve each time it opens. Used on 1973 or later heads and the exhaust valves would have hardened seats

The issue of possible shavings in the oil should be looked at as well, so an oil change and inspection of the filter is in order.

Re: Lifter Retainer Ring?
Thanks guys.
RenoKeene it's a 307, and it's possible that there are different versions. I'm not sure I'm seeing what you are seeing, and it could just be the angle, but it did have a broken timing chain and some repair work for that many years ago. Do I need to avoid cranking this up until it is repaired? |

Re: Lifter Retainer Ring?
I would fix it if it were mine before I fired it up. And change the oil. I would also get a magnetic drain plug to catch whatever metal is floating around in there.

Re: Lifter Retainer Ring?
Agreed. I would fix that & remove the shards before firing it up. And check that valve/rocker assembly closely to make sure something didn't cause that deflector to break.
As hayhauler71 said, those are rotating retainers on the exhaust. As a side note ... for the 1st couple years Chevy used shorter exhaust springs to accommodate the thicker retainers, until the machines were re-tooled cutting the spring seats lower allowing all springs to be the same.

Re: Lifter Retainer Ring?
Thanks guys. Got it replaced. I think it's probably been that way for a long time and through many oil changes, but I'll do a couple of more oil changes to be sure.

Re: Lifter Retainer Ring?
Awesome, you did it yourself! I didn't realize how clean your engine bay was in the other pics...nice!
You say it was like that for a long time...wasn't it pretty noisy? Never had this happen, so I wouldn't know...

Re: Lifter Retainer Ring?
Thanks! I didn't really do it myself. I had a mechanic friend come over and I 'assisted'. He let me do a lot of it though. I really don't know how long it's been like that and it's been sitting for the past 6 years. I've been working on restoring it for about the past year. Here's a link to the first test drive last week, just before I discovered the problem. I only discovered it because the valve cover gasket was torn and leaking a bit, so I noticed it when I replaced the gasket. I thought it sounded OK.
