cam nut removal with stromski tool
 

HI, first engine rebuild due to broken head studs. Have purchased stomski tool for cam nut removal but on the left side the chain tensioner prevents access to the nut because of the size of the tool. All my manuals show to remove nut before the chain tensioner. Is there another procedure to follow to overcome this. Many thanks Russell

Yes - take the tensioner off. You can use any number of ways of keeping tension on the chain through the idler gear - vice grips, C clamps, bits of metal between the case and some part of the idler arm will all do it. There is even a really nice tool you can put in and, by twisting it, expand its length.

ps: it is a good idea, when asking a question, to give a bit of detail about your motor. Noting it is a 19xx 3.0 or something like that is usually enough. In this case, one supposes your engine is one of the earlier ones which have the big cam nut, and not the later ones with a bolt holding these parts together.

Don't know about the Stomski tool, but using the factory crow foot socket I find it clears by just backing off the tensioner retaining nut enough to let the tensioner slide out part way, but not all the way off its post.

hi, advice taken and removed tensioner and cam nuts are now off. thanks for the advice, moving on to removing cylinders heads. Car is a 911sc 1980 which I have owned for 1988, with 103000 miles. Russell

Aside from the great Stomski tools (I own most of them), the purchase of Wayne's book on rebuilding is priceless too...
