Hey guys, I've got b18b1 with pr3's, and last night I was putting in my crower 403s. The guy I got the motor from at one point told me he'd put in crower valvetrain, but it has h22 dual valve springs.

Yes, I know it's probably not very good to be running the h22 valvetrain, but it seemed to work fine with the stock cams.

However, with the 403s in, the only way I can turn over the motor is if the valve lash is set at .020 roughly!! Anything tighter and the motor won't even turn over all the way. Spec is about .008 I think. Yes it's very bad.

But what I don't get is this: the outer valvespring doesn't bind, and I wouldn't think there'd be any way I was even close to piston to valve contatct with only 403s and pr3s.

Does it sound like the inner could be binding? I'm pretty sure the h22 valvesprings are longer, so it could be.

Or could I actually be that close to piston to valve contact? (I have a hard time thinking this one) I think I'm gonna try pulling out the inners, and tighten the lash and see if it turns over, but I have to get ahold of one of those nifty tools that pressurizes the combustion chamber. So in the meantime, what do you guys think? Thanks a bunch, sorry it's so long.

put in some stock ls spring...see if it gets better, you can also use b16's on the intake side

Inners and outers correct? I imagine, but don't like to assume.

Thanks though. All input is greatly appreciated.

 

b16 inners and outers will fit on the intake side. since the intake cams are larger than the exhaust this helps. you arent REQUIRED to use upgraded valvesprings though with those cams (strongly recommened though) so just to check you can try stock LS ones if you have them. i do have 2 sets of LS springs and a set of b16 springs.

you cant use b16 springs on the exhaust side because the spring height is larger on the exhaust on a LS head. vtec heads have the same height intake and exhaust.

 

Sweet, thanks for the info. Maybe I'll have to hit you up for some of that stuff.
