    Valve cover question

    I was installing my passenger valve cover on my 243 heads that use the 99 valve covers and I see this:



    Should I see the gasket like that? My bolts don't have the grommets on them if that matters. It makes me feel like they are not tight enough or I installed the gasket wrong some how.

    The O-ring gasket sets into a groove machined into the rocker arm cover. Honestly, I haven't paid attention to what they look like when installed. You should pick up a set of grommets for the bolts. As I recall, the recommended torque spec on them isn't all that much.

    Okay well I did put the gasket into the groove. The valve cover wiggles even though the bolts are tight, I will get some grommets and see if that helps any.

    Hey Will,

    After I sent last nights pm I got to thinking and I realize what Jeff had said about the grommets.



    Side note - ordered the 7.325 push rods, hope to have them by Friday.

    I thought about that too, I just didn't think it would make that much of a difference. I taped off everything on my drivers side and passenger head to attempt to remove the broken lifter tray bolt. Let me know how those pushrods turn out.

    I thought you already got the bolt out already. Be careful.

    No I've been lazy....college, work, kids, and family seem to take all my free time

    I covered the whole area minus the one spot I need access to with painters tape.

    Interesting. I've never really paid attention to what it looks like either. Now I'm curious.

    Do you think I blocked enough off





    That is where I need to drill. I ordered grommets and they should be here tomorrow morning. Btw I hate advance auto parts employees. They know nothing about cars and what shit is called.

    ignore my pm about how far down the broken bolt is,


    is there any edge at all to use a flat tip to turn the bolt?


    Use any penetrating oil to help loose it?

    I wounder if some carefully applied heat might help it? Maybe warm the surrounding block carefully?

    It is completely flat. I wish it didn't matter if it came out or not lol. I will try penetrating oil and my torch but I feel those won't help much since the left hand drill bit is just drilling and not even turning the bolt a tiny bit.

    Just drill it out. Pretty straight-forward process.

    sad thing is that bolt isn't even that deep....



    was looking over my wife's Jeep last night and remember I need to do this for a oil pan bolt that broke like this too. I'm luckier in that I'll be pulling the block out

    Start small and work your way up is what I've done and seen done. I don't know if there's a rule of thumb or not. 1/2? the diameter?

    Are you using a left-hand bit?

    Yes I am and none of them worked they just made things worse, they jumped twice off center on different sides. I think I am going to have to drill the hole out with a bigger bit and use a different size bolt, or use JB Weld to fill the hole and redrill it the proper size. This seems like a lot of trouble for something that isn't that critical, what I mean is the head gasket with the heads are what really hold the tray down, in addition to the bolt.

    Well my grommets came in today and I will be installing them tonight, hopefully those allow me to fully tighten down the valve cover.

    It seems the grommets made it no longer loose I will take a picture of how much gasket shows later.
