Well, got everything torn apart, rockers removed, etc, in under 2 hours . However, when it got time to swap the springs is when it got bad. First off, the valve spring compressor I had to use is a POS. The design is terrible and not user friendly. SO all in all, 6 springs were replaced in like 1 hour an a 1/2. Then, I lost a keeper because of the POS compressor. So, I have 10 more to go, but I bought a spring compressor at NAPA that's the good one, the one bent like an L that is leverage activated. But I bought some keepers but they won't be here till Thursday. Also, I had to find TDC on each piston myself (that was a fun chore), nothing like using a masking tapped screw driver to find TDC, the use some drinking straws and have to re adjust because the piston isn't at TDC like thought . But yeah, Hopefully tomorrow all the springs except the one without a keeper will be replaced and the cam is in.

Till then keep the 918s out of your signature.......LOL

 

Yea man, the springs are harder than the whole cam swap IMO. If you ever decide to do it again, the Crane valvespring tool is awesome...the first time around I used the aluminum More tool, and a claw type compressor for the rear springs, as the More tool wouldn't get straight on and I couldn't get the keepers in. Next time I did em I invested in the Crane tool and it was like night and day, made the job a snap!

 

don't worry tomorrow all sig items shall be installed.

I lost one keeper too. It sucked, I thought the "L" shaped compreser sucked, cause I broke 2 bolts off in the head trying to compress the springs enough to get the keepers out, so good luck. Also, when I did it, I found TDC on #1. I dont remember the other one at tdc at the same time, rotated 90* then didi those two cyls, so on till I had rotated the motor 360* and did all 16 springs. For what its worth, have fun

 

Yeah, I need to look into that tool when I do the next spring swap some 15K miles later. Here's a pic of the one I was using. it's the exact same as that one except the one I was using had a socket head. So I was balancing a socket and wrench on top of it trying to roate it (very tight because of spring compressed tighty) the compressor wanted to rotate so I had to hold it then keep an eye on the keepers. I felt like a ballerina! But here's the one I bought. I'll look into the crane too. Thanks for the advice!

Man, it seems nothings going to work . Hopefully I don't break any bolts, but I will! Because I screw everything up! I followed the firing order when doing my springs, less roation.

I did compressed air into the cylinder with the Crane Cam compressor. Went without a hitch and fairly quickly.

 

I ended up getting the compressor in your pic. The top one. I thought it was easy to use, but I could see where it would be a pita if you had to use a wrench. The one in your bottom pic sux bad. I would have thrown mine to you I dont even want to see that pos anymore.

 

Changing the springs out on these motors is definitely a pain in the ***. Have any of you guys used the valve spring tool from Crane that does two at a time, it makes it a hell of alot easier, kind of exspensive though. I paid like $100 for mine but I think it is worth it.
