I had a tube and large area washer and extra long bolt and I found it kinda hard too use, especially on the rear head! So I came across this old strut cap and it fits using the OEM camshaft bolt and washer! Tighten it till the cap butts up to the camshaft front and it's perfectly installed!!!

 

Nice!

That beats spending God knows how much on the Matco truck

 

Using this strut cap and the camshaft bolt and washer will guarantee a squared in seal install!

 

Damn good idea there! Props!

 

I actually used it on a Saturn Vue 3.0L (Opel) I rebuilt and it again worked great and easy !!!!
