Story:94 jdm h22 ~ 30k-40k miles
I took my head to a machine shop, had new valves/valveguides/2 new lifters put in. after 500 miles of driving, ticking noise comes in ---> 1 bad lifter
Took head back to shop, had all 8 lma's replaced (replaced all of them so it doesnt happen again)
Well, the noise is back.. just like last time..

My question is, what would cause a lifter to go bad so quickly? I've put less than 300 miles on them, not driving hard at all!
I've never heard of lma's going bad so quickly before...
Can I use the newer 2000+ LMA's without any problem? They are TONS cheaper than the older h22 lma's and It seems like a worthy upgrade

Help me out guys!

 

Anyone??

 

Bump? Have I stumped all the prelude gurus? ;P
Im struggling to find answers on this
I talked to the tech who specializes in honda engines, and even he was stumped!

 

do you have a picture of them, its kind of hard to even say what that could be with out seeing them. it could be oil starvation, valve lash too tight or anything like that. but needs to be seen to have an idea

 

the older H22's have the hydraulic LMA's right? switch over to the springs. thye should fit right in

 

When I pulled the head before, everything looked ok, nothing strange.

Yes, they are hydraulic, and they suck! The spring ones fit right in? no shims required? just a direct fit? This would be SO ideal for me, since I am home for the winter break and a honda dealership is walking distance away from me

 

OK, do me a favor. give me the code on your head on right above your exhaust ports.

where do you live in central florida? if you own a lude and live in FL, you gotta hit up http://www.sfpoa.net

 

What code are you looking for again??
And no, I dont drive a prelude, I drive an acclude

 

bump
Does anyone else have any suggestions?
I'm freakin out over this, because I dont wanna replace them AGAIN and have them go bad AGAIN

yes you can, you can use the spring type LMA in the head with no problems.
as far as them going bad.. i doubt they are bad... the old type LMA are just plain noisey.. and they are not hydralic.. they have a spring inside them too

 

Ive never heard of the LMAs going bad, let alone right after they were replaced brand new. If that were to happen i would think something else is affecting them.

 

exactly! but what would cause them to go bad?
I listened for the noise before, and it sounds like the same lifter went bad as last time...
Could the rocker assembly be bad or something?
Ill be taking it apart in the next few days (waiting on some parts to get here)


edit: Could this be an oil pressure related problem?
I didnt replace the 3 o-rings in the head (oil control orifice, and intake and exhaust orifice) Could this be causing the problem? what about a defective oil control orifice?

Did you check your last ones to see if they were bad? Hold one in your hand and push down on em, they should move back up smoothly. There is nothing fancy about em, i just cant see them going bad that easily.

 

The last ones were bad, they came apart.. and this time its the same noise as last time, so it has to be them.. It even sounds like the same one went bad, (it sounds like its in the same location)

I went to honda and orderd the new spring type LMA's and the new O-rings as well.. I dont know what else oculd be causing them to go bad...

 

Wait a minute....you have the oil control orifice in?

Is this an h23 vtec?

 

Its a jdm h22... I'm not talking about the one that goes into the block. Look at #10, that is what Im talking about.

 

ohhh ok i see

There is no doubt that early h22 LMAs have a disadvantage to the later spring type ones, but there is no reason they should be blowing out like this....

The b series guys use h22 LMAs in their huge cam heads....so these should hold up fine, I agree, I think the problem is in your oiling system....

 

Could I have a bad oil pump possibly?
I mean, what else could it be? debris in the head?

 

Do you have an oil pressure gauge?

 

No I don't.. What type of process is involved in checking the oil pressure? And if my oil pump WAS bad, would other things be malfunctioning as well?

 

BUmp once again, I'm still baffled here!!
I'm still driving the car around, performance does not seem to be affected. It sounds to me like MAYBE more than one lifter is ticking, but i am NOT SURE..
I've searched for symptoms of oil pump failure... fearing the worst
Im looking for every possible scenario here, since every tech I ask is left scratching their head.
When I install the new H22 LMA's i ordered (The newer spring type) How will these fail?? What are the symptoms?

they cant.. its just a spring.. the LMA's u have now are probably 100% not bad... they hardly go bad.. they arent apart of the oiling system, nor are the new spring types.. they are just sitting there in a hole in the head. to push back up on the vtec rocker arm.

every tech you ask probably doesnt have an answer because the problem lies else where.. or you just over analzying the situation.. if anything noise is caused by the valve to rocker arm clearance.. have you even check that??

 

Yes I have, and when I put the new ones in, I have my feeler gauges and 10mm jam nut wrench ready to adjust them to spec... for the 7th time this year

 

how do you know that the lma's are gone, my engine makes a lotof tappety noises and i just turn the stereo up have you pulled the head on this set yet?

 

It makes the same exact noise it did last time, which was an LMA. When I hit vtec, as far as I can tell the noise goes away, and no I havent pulled the head yet, nor am I going to. There is no way in hell im yanking the head off this engine for a THIRD time.
I'll be doing it with the head on the car, which apparently can be done, and I will be doing it
