Octavio, are you talking about tool #35755, for $29.50? (I got this # out of their 2000/2001 catalogue).
This is what I made for my engine, this is what will work. |

I have never adjusted valves but there is a tool advertised at international auto parts that sounds like it might work. Its listed as "valave spring compressor adaptor" and you can see a picture if you look at the pdf catalog under tools. The website is www.international-auto.com |

Ah! And I thank both of you for elaborating - and saving me from buying the wrong thing. I wish I had a head sitting around to help me figure out what a tool would have to look like to fit. Maybe I'll make a call around to some ofthe guys in the bay area who work on the older cars and see what they can turn me on to.
thanks,
Rich |

My point exactly. I thought that you had made yours I just didn't want Richard buying a useless tool. Thanks for elaborating. Brgds |

No Magoo, what I used was a simple bar clamp and onto this I made an attachment (tubular, with holes cut out on the sides) to compress the springs whilst removing the keepers. This tool was only effective with the heads off the block. In Richard's case, he'd like to do it without removing the heads. And yes, if the Snap-On tool removes typical valve springs, it won't work on the Dino (typical removal tools use a fork-like end to press down on the spring cap. The valves on the Dino and other Ferraris are buried in cavities and the fork of the tool will not go down into it). |

Course then again, I guess Snap On knows what they are selling. Richard, having said all this you can be pretty sure it isn't a universal tool. |

Peter, I know you used one. Doesn't it have to be a special slender type of tool to get down in between the collar on a 308 head to compress the spring? |

Thanks guys.Now that I know such a thing exists, I searched the snap-on website and I think I found it. No image is available but the description sounds right. Part # VST100�
And at $30, it's got to be one of the cheapest things you can buy from Snap On -- and certainly worth it compared to the time/expense to pull the head(s)!
I sure hope this isn't a tool that I will be using often - so if anyone ever needs to borrow it just let me know.
Thanks,

There is a tool system to do that. At TDC, the combustion chamber is pressurized with your shop air-compressor, through a fitting mounted in the spark-plug hole, a levered arm is bolted to a camshaft bearing cap and the end of this arm pushes down on the valve spring cap (the air pressure keeps the valve up and tight). You then may remove the springs and access the seals. I don't know if it can a Dino motor. I think Westward makes one, I'm positive Snap-On has one. |

Difficult to see how it could be done on the forward bank 5-8, you could easily modify something out of Baum tools VW to compress the valve spring after removing the appropriate cam and pressurising the cylinder. We do it all the time at the track on different cars. |

Is there a fancy tool out there somewhere that would make it possible to compress the valve spring to change a valve seal with the head on the car?
