Started tearing into the motor after work. Didn't hit it real hard. I'll have the cam out before the other cam gets back to me.

Found one more cracked rocker. I'm so sick of valve train issues. Hopefully this will put it all to bed.

What rockers are you using Craig? Friend of mine busted an intake rocker last weekend causing a melted down cylinder, pretty sure that one was a Jesel. Not sure I like aluminum ugh..

Jesel. I'm confident the problem is the inner coil bind. Hopefully that's been most of the pushrod problem too.

It probably didn't help anything that's for sure. Valve train problems suck.

I'm going to pull the tranny and take out the restrictors too. I don't think my block has to have them for any passage sealing purposes but I'll look closely to be sure. I've always run them in this block.

I sent the rockers back to Jesel and the cam back to Bullet today. Hopefully I'll have them back soon.

Craig - sorry to hear you're having issues with your gear.

I've been running these new Jesel rockers now for the last couple of weeks and they seem to be doing fine so far... I was concerned about the geometry on the setup but it seems (so far) to be ok. At least it didn't hand grenade at startup so I'm hopeful.

I'll be swapping and peeling the filter later this week to see if the motor is shedding hardware. I'm hoping for a clean bill of health. So far so good.

Hope you get to the bottom of your issues and get them fixed.

Found my fuel leak. It wasn't a porous weld in the new fuel cell after all. The 10AN to 8AN reducers were bottoming out against the bung welds before sealing. I'll chuck them up in the lathe at work on Monday and take .050-.060" off and all should be good. I'm glad the new trunk paint doesn't seem to be harmed.

The bad news is I found a third cracked rocker. While rolling the motor over by hand to remove the rockers, I saw it flex and weep a little oil from the crack. It was really hard to see when not under a load. I rechecked all the others under a load and didn't find any more. This is starting to get expensive.

My cam shipped from Bullet today. I sent it back Monday and they got it Wednesday. Got right on it and took the time to talk over the application with me for about a 1/2 hour. We decided to calm down the aggressiveness, take a little lift out of all the lobes and add a little duration to the exhaust.

Hopefully Jesel is moving along on the rockers.

Are these the sportsman rockers or the pro series ones? I have the Sportsman ones on my big block and I hate them.

Pro series. Its not the rocker's fault. Its the engine builders fault. That would be me! LOL

I incorrectly thought that my backup cam had less lift. When I broke a lifter early last year, I put in the backup cam so I wouldn't miss a race. It ran well so I left it. I missed the fact that I was getting coil bind on the inner valve springs.

From one nitrous small block guy to another, care to share the specs you & Bullet decided on for the new grind? What ratios are your Jesels?

Oh Ok, I could see that being a problem.

Sure Mike, I don't care to share the cam specs. I don't have the lobe numbers with me right now but if my memory is correct the intake is 278@.050, the exhaust is 311@.050 and its a 115 lsa. 1.9 intake and 1.8 exhaust rockers. Lift will be about .890/.850". Mark said the extra exhaust duration would widen my tuning window.
