I have to replace the head gasket on my 06 hummer h3 cause when I did it the first time I got a peice of the exhaust manifold gasket wedged in it. This time I don't want to have to drop the oil pan and everything else. I want to make my own lower timing chain holding tool. I have several different scraps of wood I can use to make my own wedge the only thing I need is the accual dimensions of the wedge.

Basically what degree slope it has and how thick it is on each end. If anyone has this tool or has made there own tool before and could help that would be greatly appreciated.

 

Were you able to find dimensions for the wedge tool? I found it rather odd that there wasn't a single reply to this post...

 

I did get them I made a homemade one out of wood that worked but wasnt the best. I have attached pictures
I used a deepwell socket and an extension to lightly tap it into place. Once it was all back together I used one of those long grabbing tools to retrieve it. You have to be careful with it cause it aint perfect but it did work for me
