Hey guys Im getting ready to tear into the head Im in need of the cam holding tool as well as the valve spring tool where I dont have to remove the head. Also if anyone has some pictures from when they replaced the balance shafts with neutrals I would greatly appreciate it.

 

you dont need a cam holding tool

 

Does anyone other than ZZP have a tool to do valve springs w/o removing the head?

 

snaop on or lisletools may

 

i got one

 

i dooo

 

jbp sells one and they want 300 bucks for it just seeing if someone had one laying around and I was talking about the tool that holds the cam gears in place so you dont lose timing.

camholding tool or valve spring tool?

 

you dont need a cam holding tool you just need an open end wrench, the size escapes me right now and I have the valve spring tool

 

its a 15/16 and this engine is easey to retime

 

Its very easy both the cam gears and crank are mark to coinside with the chain

 

no **** you dont say

 

whatever you do, don't be lazy. pull the front cover and double check your timing

 

My Guy does this as well

 

Would you be interested in selling and is this the tool that I would not have to remove the head.

 

It's no secret or special tool... Kent Moore makes one version of the tools, and it can be found online cheap...

The tools can be had for under $100 if you look around, even cheaper if you use the open end wrench trick (can someone please explain that more). The cam sprocket bolts are about $65 from CED.

You need to apply air pressure to the cylinder through the spark plug hole to keep the vavle seated while you use an overhead spring compressor to push down on the spring, remove the retainers, replace with new spring, etc. Same as changing valve springs on many other engines...

Thanks for the information I knew about putting air pressure to the cylinder head(I used to do that on old v6 and v8's) but everyone made it sounds like this couldnt be used for one reason or another. If you have tested this, fantastic and I know that I can start my project that much sooner for finance reasons.

 

I've never done it, but I know how lol. Good luck. Take pics for a howto or something.

BTW, why springs? On a M62 the power will drop off hard once you get so high.

Who can elaborate on the wrench trick for keeping the cams aligned with the chain off? Is it as simple as putting a wrench on the cam sprocket bolt and propping the other end against the other sprocket?

 

Unless the person has ever taken the valve cover off and the front timing cover they would not no that, we don't need people like you on this forum that mainly why it sucks. Because when someone asks a question and doesn't phrase it just right oh no here comes mrbelvedere to make a ******** comment. Regardless ofwhat you think you don't know everything, neither do i, but I share what I know and that is suppose to be what this forum is for, a sharing of information about a platform we all love. So kindly shut the **** up unless you have something half intelligent to say
