Actually I have been meaning to post. I submerge the lifter in a pan or small container of oil. Using a drill press with a rod to compress them and pump them up. You judge the condition in comparison to the others. Ideally using one new one as a standard. Not a necessity though usually.
Specifically you are looking for too rapid leak downs. Or inability to pump up. I would do this check in my case twice. Once when first removed to spot any really serious ones. Plus again after cleaning and putting the lifter back together. If there is too much wear in one. You could clean and change nothing. Laquer thinner is good at sludge and varnish removal. When you soak parts in it try to keep it covered. It evaporates faster than many other solvents. Plus can intoxicate you. Or has an effect like that when the fumes are thick enough. As mentioned doing the soaking of the individual parts of one lifter in a glass jar with a screw on lid would work nicely. Anyone should be able to find a few surplus bottles to do this in. Childs baby food bottles would be ideal. In my mind this beats pulling the cam and lifters and reinstalling them only to find you had a couple with too much wear that did not respond to cleaning. The loading you can apply with a drill press after they are pumped up is far more substantial than a simple hand powered test. Depending on a lot of factors adding miracle mystery oil to the base oil. Has been known to produce good results. For the low cost of the product and lack of effort I would try it first. I am not a heavy believer in additives. Still this product has been around for almost forever and seems to do certain things decently at times. I just consider it a roll of the dice. With some possible potential. Turpentine seems to be the incorporated primary solvent in the product. To me even my having low chemical knowledge it is a strange one. Perhaps that is why the product is different than the run of the mill snake oils. Why test my way? It is pretty reliable and if you still have lifter noise after. Probabilities are a piece of head gasket at one time is lodged in the oil feeder passage or it may be sludged up. Or for some other reason the lifters are not getting enough oil supplied to work well. You have eliminated the lifters as a problem by testing them. Another benift is if they all test very well when first extracted. You should become suspicious. I do many things that are perhaps not quite run of the mill. I just post some of them from time to time for consideration. Most work well for me so they may work for others. Some I totally originate and others like this are just good established long term practice basically. Last edited by barry12345; 04-17-2017 at 03:04 PM. |

The valve cover gaskets are re-usable. They do not need to be replaced unless they leak. I've had the valve cover on my OM603 on and off numerous times over ten years, and I have not yet replaced the gasket.

Bad news the piston wont come out. I keep smacking them with no effect, other than hurting my hand. https://www.youtube.com/watch?v=ySf0r8GGMOY&feature=youtu.be Tried just like video above

They didn't come out like that for me either. I used a set of pliers with rubber pads on the jaws (clean off any oil first or the rubber will just slip) and they pulled out. They're NOT easy to get out. Wiggle back and forth a bit, then give a sharp tug and they should come out. If they're really varnished in there, you may have to pull pretty hard.

There was no special tool. I cut the finger tips off some old heavy duty rubber gloves and slid them over the jaws of the pliers. Keeps from scoring up the chrome surface of the hydraulic piston

I had two hands on the pliers, brother haf two hands on lifter.
I pulled and still nothing. I'm out of options, and frustrated.

If the piston is literally lodged inside of the tappet to the extent it wont come out, then i'll just have to flatout replace the tappets I presume?

Patience and Perseverance are both virtues, often not found together.
The piston is *VERY* tightly fit into the tappet. You must have a *VERY* firm grip on it and give it a *VERY* firm pull to get it out. Some of mine were far more stuck than others, I used a set of rubber-jawed bar clamps to hold them against the table so that I could really work the piston out. Grab firmly and rock as you pull. It'll come out. Be prepared for sticky, horrible, STINKY sludge when you get them out too. |

I recently replaced my lifters even though they all passed the "push test". I had bought the new ones and couldn't return them, so WTH.
Anyway, I have a full set of lifters that have 153k on them. I was thinking of listing them on eBay but I'm not sure if they can be used in a different engine (lots of opinions here...) If you end up needing new parts and don't want to spring for a set of INA lifters, PM me and we can work something out.

I may buy a few if I loose a spring or retaining clip.
Right now they're sitting in mineral spirits until I get oil Friday.

Ok more bad news, there are small rust spots on some of the lifters.
I'll dunk them in water and borax to rinse out the mineral spirits Since I'm on a budget I'll soak them in vinegar to loosen up the rust. Then I'll quickly wipe away the rust and spray them down or dunk them in water and borax solution to rinse out the vinegar. Supposedly the Borax inhibits rusting. Finally I'll spray down the lifters in WD-40, assemble, and install. Hopefully this will quiet down the noise. Yes, new oil and diesel purge will be done as well. I've learned a lot taking it apart, hopefully it is worth it.

Rust spots should be causing an eyebrow to raise. Usually the tappets are completely bathed in oil, so even when sitting they shouldn't rust. Mine sat in a field for 10 years and still didn't have rust despite the oil turning to jello.
Where is the rust? Can you provide a picture? It might be worth your time to have an oil analysis done to find out if you have coolant in the oil. The heads on these engines are well known for cracking and the head gaskets well known for blowing and leaking. Coolant in oil is one of the symptoms. |
