You need to see if the gasket surface on the head is truly flat as well as the exhaust flange and correct things as needed. |
Ahh - guys. The #5 outboard exhaust stud is missing. This could cause a leak! ;)
I'll bet that there was a stud there, but its current absence might indicate a problem with torquing it down adequately. Please no doubling of gaskets! Address this stud first. |
Not only one missing but there is different length studs in the soup too. We can see the blowby but was #6 ever tight?

Hello,
Thank you for the replies! I ordered a new stud for # 5...yes I couldn't get the cap nut off the stud so it screwed in as a whole unit. # 6 studs had to be replaced and drilled and tapped. I put new studs in but they would not go in all the way. I used a couple washers with the copper lock nuts to hold them on...it appears to be working good...I know not perfect but....OK no double gaskets :) Again the noise was from #6 as I put a hose to my ear and placed it on each cylinder. I may have jumped the gun but i thought better safe than sorry. I'll get the new valves put in next week for #6 and have it checked over. Thanks again! Alan |
be sure the guy checks the valve to seat contact, especially #6 exhaust, as you said the coloring was uneven, possibly indicating a leak. regrind the seat if needed. reground cams often cause a tick if not done properly. i would bet that #5 exhaust leak was the culprit though.

Hello,
Thanks for the reply. I appreciate your valuable input. I took the head in and had new valves put in it and had it checked over all seemed OK...Ya, your prob right. I guess I'm nervous...my first rebuild. I just don't want to screw something major up. I should have it put back together by Thursday. I am installing a new stud on #5 with anew cap nut also. And yes a different rocker arm for #6 exhaust. Thank you again! Alan |
Yea! Its fixed! Shop thought it was the exhaust valve not seating properly...they put a new one in for free ... I also replaced the intake valve and rocker arm and no more ticking!!!!! Just got back from a drive and all is quiet!!!! I very happy :) Yes, I also fixed the exhaust leak on # 5 :) Wow! A lot of work! Thanks too all who helped with replies! I'm sure there'll be more issues but all is good for now!
Thanks again! Alan |
