LIFTER LEAK DOWN

Postby rono24 » Wed Mar 12, 2014 7:15 pm



If my 1992 sits for any time the lifters leak down and it is hard to start and of course runs poorly untill they pump up any suggestions

What have you done to conclude "lifter" leak down?

A little more detail on hard to start would be helpful.

What is the mileage?
This is what I do
Local and need repair help with your 1500, Valkyrie or ST please PM

Let me make this simple hydraulic lifters use oil as the fluid to keep them pumped up to do the job they are designed to do which is to open the valves to there proper opening so the engine can breathe properly intake gas and exhaust burnt gases. If the pressure bleeds off they will not do their job as designed and that is what is happening with mine,how do I know this,I have been a mechanic all my life and believe me I know this is what is happening,what I want to know if anyone knows if this is normal thing that happens to this particular engine or if there is a fix for this.

Perhaps a little more information about your bike would help...

How many miles are on it?
Do you have a record of maintenance?
Was the oil changed regularly?
Which type/brand of oil ?

Anything else that might be pertinent to the conversation.

As far as the reported problem..I have never heard of this for anyone owning a GL1500 (not saying it doesn't happen)
But the GL1500 has been as reliable as a hammer for years and years and millions of miles for people.
So yours may be experiencing something unreported by others..?

Have you run any Seafoam through the oil system to clean out the aging crud ?
That sometimes helps oil related issues (rare as they are) ...

Just throwing out ideas....

One riders 88 had a similar problem at about 250k. He changed from 10w40 oil to a 20w50 and it sounded a lot better. He has over 300k now.

Ill do some looking but as I recall,the hydraulic lifters are not designed to hold pressure.They fill with oil and are pre-set clearance.The oil pressure at running helps maintain the zero lash.
Now if the lifters were out of pre-adjustment due to wear or rebuild all bets are off.
I don't believe there like the ones in a car that move on the cam.They are fixed solid and act like a spring keeping the valve lash at zero.
Be aware that the 1500 is normally difficult to start after setting a week or two.We/I have had this problem.It turns out being low voltage to the ECM module.A need for a hot battery.
You could prove this out..When you expect the bike will be hard to start,throw a charger on the battery for a couple of hours.Watch the tach when its hard starting too.When mine would crank but not start,I saw that the tach would also not move much,No/erratic spark.

Another question.Does your bike have excessive tapper noise on startup.??
So far my 88 takes about 2-4 seconds of cranking to fire off,plenty of time to build enough oil pressure to tighten the rockers up.Ive never heard any ticking yet.

Virgil is correct, the lifters (more correctly, hydraulic valve lash adjusters) do not hold pressure, so they cannot leak down. When the engine is off, the adjusters hold no oil and no pressure. Upon cranking, engine oil under pressure is applied and they pump up to adjust valve lash to zero. If your engine is started, and is running rough with tapping due to excessive valve lash, you have one or all of the following:

- Excessive valve lash for which the lifters cannot compensate
- Clogged oil channels not allowing thick, cold oil to easily move into the adjusters
- Insufficient oil pressure
- Incorrect oil weight

I'd echo others - try a dose of Seafoam to try to clear out any clogged channels, then do an oil change with a quality synthetic, and see if it makes any difference.

I bought the bike in jury with 68 thousand on it,do not know about any maintenance history, I am running 10-40 synthetic and thinking about going to heavier oil. I am going to put some sea foam in it before I change oil this time.
Virgil I was also thinking that the lifters were as you stated honda cars used this system many years ago.
Thanks for all the feedback I really appreciate it.

Ill do the reading about their adjustments.That will yield the answers by how there adjusted.
The only time I've ever heard of "lifter"problems were on the 1200 with oil foaming.
Does yours tick when it starts up.??

If it has set for a couple of days,which is not often in the summer, it does and runs rough UNTILL the tick goes away.that is why I am sure it is lifters.

Ok.Now I know there is ticking on a cold startup and delayed quiet.
Obviously there's a problem,now let's recearch possible causes.
Time to hit the books. :D
Seems to me that I read somewhere that the 1200 used a reserve container of sorts for the lifters.I vaguely remember it being called a de-foaming tank...or something like that.
I wonder if its possible that there is simply air trapped in the lifter assemblies.Ill read bout that too.
Oil change is good anyways.A lot of us use the Diesel oil too.
I actually run Rotella 20-50 in mine year round.
Its funny that your bike takes so long to pressurize the lifters.
Next time you notice..without actually starting the engine,just cranking,see how long it takes for the oil light to go off.
I just checked mine.50* degrees out.Not started in 2 weeks.Kill switch off.Cranking the engine.The oil light flickers off right at 4 seconds.

Update,just started bike after sitting for for almost a week,no lifter noise started right up. Have not changed oil yet but will soon put in some sea foam will then change to rotella oil.
