how do u like ur gmr cams cobalt5ss? how much did they run u?

 

Hopefully il get to meet you at one of the meets then

And area was trying to help you, Thats how he rolls

Encase you didnt know he is one of the most knowledgeable, If not the most knowledgeable LSJ guy here

 

oh boo whoo. he wasnt stabbing. he was simply stating that ur lash adjusters probably hate you. thats all. he wasnt saying its ur fault or ur dumb. just stating a fact that the GMR cams are bad for ur lash adjusters. calm ur self sir.

 

99% of people don't realize that the stock lash adjusters don't work with regrinds. Area, myself, and a few others, have experienced it firsthand.

I don't know where the sudden surge of people looking for cams is coming from, but there are other, better ways to make power on these motors. You are looking at $1000 MINIMUM in parts for cams, and the power gains will be very modearate. Not a starter mod at all.

 

Money aside the maintenance alone on solid lash adjusters isnt worth the gains on a street car.

 

that was one mod i heard of doing but u know best so pm me a way of make more power with no cams

 

What is the adjustment interval on the aftermarket solid ones, if you know? That was one question I did have that I never saw an answer for.

 

i plan on doing the whole motor at once. the head will be P&P with full valve train

 

That comment wasn't directed at anyone in particular, I just see a lot of people taking interest in cams all of a sudden. I'd advise people to do the basics first, and hold off on cams until you are ready to do a full head and new pistons. IMO.

 

oh ok

 

depends on how you drive it and for how long.
my 240/280z engines had solid/mechanical adjusters that needed to be done every 15k miles. most v8 guys i know with solid lifters are track only cars and run the valve before every race

 

Yeah, when my dad had the Z shop, I used to do the early Z car ones all the time. I was just wondering if anyone had any experience with BLE or similar aftermarket ones. Obviously, full race situations are different, and adjusting them every week would be severe overkill on a street car. Just wondering.

 

I think there is a bit of confusion about how solid lash adjusters work compared to solid lifters. While they perform the same basic job, they do so quite differently. If a solid lash adjuster is set properly, it should make it a very long time without issue, I'd imagine 50k+ miles.

Of course, if someone would just come out with an oversized hydraulic lash adjuster, we wouldn't need to argue about this anymore.

 

From what I understand, people were using shims originally, but there were issues with reliability with them. Nobody is going to engineer a factory style lash adjuster that is bigger just for regrind cams, too much expense for a very minimal market.

I was thinking what you said though, I know some of the newer Honda motors and others use solid lash adjusters for better valvetrain control, and they don't need to be adjusted every year or whatever.

 

you cant shim the lsj heads....

 

I wouldnt let valves go 50k without adjustment. The absolute newest Hondas Ive seen with solid cams list a 30k mile interval, traditionally for them it was 15k. On my Vette I did it every oil change, and virtually everything I am aware of in the remotely reasonable priced category(from dirt bikes to Civics, to MBs) is somewhere between 6k-15k miles.

The problem with the Cobalt is( if youre running solid lash posts, youre probably running a serios cam and seriosu springs, which means more valve and seat stress, so I would say that 5k mile interval would probably be what i would go with. Tight valves are bad, umkay


I dont think there was anything "wrong" with shims, other than the fact that you need to keep a selection of shims, which gets expensive for a full kit. and really sucks when you drop the box. Adjustables are just more convenient.

Um?


The problem isnt even in checking your lash, its not really any harder than checking it on a Honda engine, the problem come sif yu actually have to adjust it. With the shim type you MUST remove the cams to adjust lash, Ive never used the adjustable ones for an ECO but you probably have to remove cams for that too unless they come with some special tools.

 

you cannot shim the lifters to adjust the lash in these heads you need to buy over sized solid lifteres and have ground down to make correct adjustments!

 

that is not the reason why you "shouldn't" shim the lsj head.

 

What is the real reason? I remember Alpha having a bunch of problems with his head, but I don't remember the actual source.

 

cause they spit em out lol. But seriously that was one of the issues. I'm looking at the BLE setup for my car, just gonna have to make a wrench so I can adjust em wth the head assembled

 

I thought it was something like that, I remember he did a bunch of damage inside the head at one point.
