Um....every 3000km = about 1800 miles?

Also, there was somebody on here that completely rebuilt all of his lifters with new parts....ticking solved

I think being proactive is the only true way....keeping the lash in check per the maintenance schedule, and using Auto-Rx on a regular maintenance basis when the engine is still young.

I'd tend to disagree that it can't be fixed. Especially since we now know there's tappets involved. (well, at least I just learned that). Those are known to freeze up with gunk and not function properly. Clean or new tappets would surely solve most problems there. If a rocker is causing tap, it should be replaced, and I doubt a cam could ever tap like that, it's a constant contact device.

LOL, sure they would.
I doubt anyone's going to re-do the job just to take photos, however.

Maybe the next will think ahead and take photos as they work.

anyone know if the g2 type II motor has tappets?

KAHruzer

Don't know, but would tend to think they might since the G1 does.

You'd probably get a better reply in the G2 section, however.

i am not an expert on posting instructions but i hope this will help some one like it did for me:

1.Need to have these items to start this project.
A)Tappets removed from your engine heads
B)Mineral spirits solvent
C)Container
D)Clean rag
E)Latex or some type of gloves (optional)


2.Drain any oil from tappets don't forget to use gloves



3.In the container pour some mineral spirits about a quart for 12 tappets (one head) i only show 5 for the pic then just let them soak for some time i overnight the soak on mine.




4.After soaking the tappets clean each tappet in the container by pressing in and out and at the same time observe for spring action when you press down the "ball" shape part the tappet should go in very easy then realese it and the tappet should come back to it's normal position in a spring motion if you find any problem with this function need to re-soak the tappets with these problems, if after the second cleaning the tappets still not operating properly the you need to replaced them.



5.Last just clean and dry tappets then recharge with oil (see manual on how to recharge with oil).

Hope this helps...

I will test the theory of 3k mile oil changes.
I have 33k miles on my 1990 with no ticking. I change my oil ~3k miles and will do so in the future. We'll see if the lifter noise never appears.

On the cleaning issue, there is a guy that I know in Switzerland who owns a collection of very rare old cars such as GTB4 Daytona, 300 SL gullwing, and the like. He does all of the work himself on all of his cars.
I talked to him about lifter ticking issues. His advice was to drain the oil, put ~2 quarts of diesel gas into the crank case and run the engine for no more than 30 seconds. Then drain the case and replace the filter and oil.

Diesel in the crankcase I am convinced would cure sticky lifters, though, I wouldn't run just straight diesel, more like a 60/40 mix of diesel and oil repsectively. I have wanted to test this theory for a while but I am not keen to do it on my Legend as I need it to get to work
My only concern is that although diesel is very slippery it could cause some damage to the cam and crankshaft by not having that thick oil coating on them. (Metal to metal contact )

i do not think that will be good idea better to use engine detergent or some type of engine treatment...

Here's a diagram in the manual (1987 Coupe, page 6-20) of a Section through the valve train. It's not as I was imagining, but clearly shows how this becomes a problem of tick noise.

The Tappets are situated as the backup bearing point of the cam motion, such that each press of a rocker arm by the cam lobe distributes that load as a span between the valve stem/push rod (on exhaust valves) and the Tappet. Not only does this ease the loading of the mechanism to half the span, but the Tappet plugger motion dampens the load to smooth it out considerably. When the Tappet plunger doesn't move, TICK!

Clear as mud, right?
IAC, clean, well functioning Tappets will very likely eliminate any ticking.
The hard part is clogged Tappet plungers are hard to clean with simple additives. So, Car2n's external cleaning solution is the way to go here.

To do so, however, requires removal of the cam and both intake rocker arms and upper exhaust rocker arms to gain access to the Tappets below.

Just wanted to say thanks for the illustarative and informative pics and story on the ticking hydraulic lifter (tappet) issue. This has been discussed at length for a long time, but this really laid it all out well. As they say, a picture is worth a 1000 words.

I have 2 questions...

The lifters that were clogged and sticky, were they the exhaust or intake tappets only, or a mix of both?

And, can you tell by looking at the hydraulic lifter once it has been removed, that it is probably a sticky one, like varnish deposits, gummed up externally, or an obviously clogged oil port?

IkeRay

does anyone know if the tappets could be purchased from a dealer, or would you have to get them from another engine?

digger89L

The hydraulic lifters (tappets in the diagram) are available from dealers (part #14540-PL2-000 ). Delray Acura sells them for $37 each (you'll need 12).
Interestingly enough, Majestic Honda has the same part listed for a 96 Accord V-6 ...using the exact same diagram as for the Acura engine (it is the same, after all) ...but they want $53 each for the lifters!!

Don't know of any after-market sources for something like this, but there likely is one.

My 90LS has "the tick" ...I tried the transmission fluid trick before my last oil change (drained off a litre of dirty oil, and added a litre of DEXRON II then went for a 20 minute highway drive). It has quieten down a bit, but not a whole lot.

The answer is YES.
