| Post subject: | Why timing chain cover install so difficult? |
I just finished replacing a timing chain on my daily driver workhorse('63 Belvedere,225 slant).The part of the job that always gives me difficulty is installing the timing chain cover.I have 3 bolts on each side of the oil pan backed off and I use a screw driver on each side to act as a wedge to pry down on the pan to allow the dowels to align in the chain cover.The rubber pan gasket gives me fits since it moves because of the tight fit.Plenty of sealant is used in the corners.Don't ask me how but I was able to get the cover on without any leaks.I dread the next time I have to do this job again. Does anybody know of a better technique? pgonsi@optonline.net |

Back off more bolts. When I was assembling my new "Screamin' Six" engine a couple months ago, I had done a wonderful job of putting on the oil pan, and all the gaskets and RTV were just right, and all the bolts were tightened down... then I realized I had to back them off to get the timing cover on! Fortunately, since the /6 cover had locating pins, it was easy to align, just a bit nerve-wracking having to touch the oil pan after I just got it all sealed up! However I was lucky and there were no leaks. The valve cover gasket is a different story. The bolt above #5 spark plug leaks with a brand new gasket on it. |

Yup, sometimes the factory got a little carrier away with drilling / tapping those valve cover bolt holes and broke through into the pushrod chamber. This allows oil mist to work it's way up the bolt threads and out at the valve cover surface. DD |
