hi everybody..... question about hydraulic lash adjusters for valve lifters

Post by KingpinCEO » Tue Feb 04, 2020 10:15 am

Hi all, :cheers

Remember me? I been busy. one of my merkurs burnt down a few years ago, I still have my yellow XR... heres a refresher from back when it was white-ish

the replacement for the burnt merkur is a 2008 turbo Subaru.

my yellow merkur is a garage/show queen mostly. I plan on going to Carlisle 2020.


Anyway, I have a 2005 dodge magnum that I had since 2005.. it finally blew headgaskets after 335,000 miles. I just finished repairing it yesterday, took about 12 days. But now I hear a lot of chatter in the valve covers, I think its my hydraulic lash adjusters.

Question: does anyone know if hydraulic lash adjusters bleed on their own? or do I need to bleed them? What happens if I don't bleed them? will it just be noisy? will anything get damaged?

- I couldn't find anything specific to my car online, nothing on youtube... the factory service manual shows a special tool and a bleeding process, but it doesn't say that I HAVE to do it.... so I'm asking you car guys if you can share your knowledge with me

thanks!

I have never come across it, but read about air being trapped in lifters. Then taking them out to see if any feel spongy. Weird because you would think it would work itself out and fill up with oil like it should. I had older cars that I figured needed new lifters (noisy) but after a few hundred miles they started working like they should. Car had sat a lot and I think old cruddy oil was trapped in there and the check ball wasn't moving like it should. But new ones? Maybe they sent you the wrong length pushrods? And the lifters just can't adjust enough to take up the gap.

Thanks. the valves ticking went away after about 5 miles.. now its quiet. so I guess it was just the dry cylinder head, maybe the assembly lube working itself away also.
