Hey people
I've come across some conflicting info on which of those springs are easier on the timing chain and tensioner.... what would you guys recommend?
I'll be running a single chain with YT 1.95 roller rockers (yes, they are still available here in Aus)
Cheers

105s

Crow 105's or like I did after much research, the L76's... Pretty much the same for what it's worth and the L76's are just a few bucks each. You have to buy 15 of them, if purchased from dealer as they come in 5 packs.
Viton sealsas well, Manley retainers... Stock locks are ok to re-use.
Taking the springs off...
Installed : )
Just a few picks to entice you... Lolz

Where did you get that valve spring compressor?

Buying one right now lol

I like using mine, I can clear a head in about 10 minutes with one.

Cheers guys
So would it be safe to say the difference in tensioner wear between the two is negligible?
L76 springs are insanely expensive here... $27 EACH lol. Crow 105s are a lot cheaper.
And how long would a single chain and tensioner last with those?
Would it be enough to check up on the tensioner every 5000 miles or so? Whats the rule of thumb here?

Crow 105s will have less strain on the dampener and chain.
The l76s will be harsher on it.
The Crows are just a better and smarter purchase in this case.
03-05-2013
Could of sworn L46 springs are like $3-4 each
03-05-2013
Here in Australia car parts are more expensive :-( especially at dealerships....
Ok il grab a set of crow 105s then cheers.
What would be a good interval to inspect the tensioner?
03-05-2013
It should be good for a long time. I wouldn't worry about it in the next 90k miles lol
03-05-2013
Crow's are an Aussie company if I recall correctly, lol, so they should be cheaper. L76's for that much is insane! 10x the cost here... The Crow 105's have less seat pressure so less wear, but I don't remember there being a huge difference. The spring compressor was from Harbor Freight and worked perfectly!
120 PSI on the hose into the cylinder to keep the valves up while changing the springs (if you don't remove heads). I had a hard time finding that info., lol, so just thought I'd share it. Make sure you have a small pencil like tool with magnet on the end for taking the locks off and putting them back! Don't think I could've done it without that!

and if you drop a valve like I did..prepare to b***h and remove the heads.

Hey what about LS1 stock springs?
Are they a bit better than stock L67 springs?
03-06-2013
No they are worse.
03-06-2013
I doubled up on preventing that, it's a bit tricky, but the cylinder I was working on I moved to TDC and then put the air in... You have to be spot on or the air pushes the cylinder down, but it made me more comfy and less worried. Takes more time too, but worth it IMHO.
: )

I really wish I didn't drop the valve lol it ended up leading to other things like taking the heads to machine shop to get resurfaced and valve job done
03-06-2013
I would use the crow 105's and inspect the timing chain and tensioner every 40k miles.

For 1.95 rollers, just use stock.
