Okay, I am sure my lost motion assemblies are broken. Have done alot of reading on honda-tech and I am quite sure the symptoms I experience are signs of LMA failure.

For you guys that swapped them out, how many of them were faulty and required replacement? These things are expensive and I wish to buy just a few to get the broken ones replaced. Maybe an estimate will be good. I believe not every single LMA has failed, or my engine will sound like a bucket of marbles. I'm sure some of you will say just replace them all, but if I wasn't replacing my timing belt and water pump at the same time, replacing all of 8 LMAs will definitely not be as heavy on the pockets.

 

Even though i've never changed any of mine or ever even seen any broken, i've seen some for sale a while ago. You should check in the general market place.

 

Have you pulled the valve cover yet? I would take a look at the head and post pictures. Several here are very knowledgable on the topic of headwork. One of our Expo sponsors is Aquafina. He does quite a bit of headwork and could probably answer your questions better than most. Keep a tally on the prices of replacements. A new head from Len(another Expo sponsor) is in the $1650 range.

 

FYI: The old part # for b-series LMA has been superceeded to 14820-PCB-305. New style like s2k/K series.

New heads and new blocks are a waste of money. Grab a helms and do some work.

It is economical to buy new trans' when a complete rebuild is in order though, as those parts costs start adding up when you rebuild one. Not true in any sense for engines though.

 

Thanks for the inputs.

 

i was told that LMA can be replaced with h22a lma or the b16 lma. Only becuase the type r lma are like 200 bucks each.

 

$200 for the entire set or each?
Take a look here. An old cost sheet I have shows each at $34.05

Maybe for a Honda Prelude sure, but for an ITR no. New factory heads and short-blocks are great and tons of ITR owners have replaced their high mileage assemblies with new factory engines, easier, faster and the precision of factory Honda technicians vs. that of your local machine shop.

BTW its a Helm manual, not Helms. Its Helm Incorporated.

 

well you maybe correct ... I was just told that the type R part number was more then the others ,but same ideal fix. I was actually told that the h22s are better.

 

inlinefour has LMA's like $200 for a set of 8... I'm doin mine this winter lol the R sounds like a chatterbox

 

yeah thats the h22's that they say are the new and improved.... ....
