    Well, I just thought I'd share an unsuccesful attempt. I just redid my manifold gaskets in an attempt to fix an oil leak, start her up and to my surprise, a worse oil leak! SOB! I'm thinking that it's the oil pressure sensor on the back of the block right there, I thought I tightened it up enough, but it stopped spinning on the manifold. As soon as the motor cools down, takin it off and wrapping the hell out of it with teflon tape and seeing where that gets me. Only thing I've noticed is the truck feels more sluggish now that before. I'm fairly pissed at the moment, so some encouraging words could benice.... :)

    Thanks for listening to my rant,

    If it is your oil press. sending unit replace it. Those things are so thin that they crack real easy. If you do install a new one install it with the proper socket (they make special sending unit sockets) so that the new one does not get distroied.

    UPDATE: Just ate and decided to go have a look I notice a few problems... First, my dumb self didn't use enough RTV for the back seal, so there's my leak, a damn waterfall of oil gracefully flowing down the back of the block. Second Edelbrock recommends the following: CAUTION: Fel-Pro brand Permatorque gaskets are not recommended for use with aluminum intake manifolds. Fel-Pro Printoseal gaskets would be a better choice.

    Guess what the guy at the parts counter handed me, I didn't even think twice about it. Looks as though I'll be redoing my manifold for the 2nd time today. On a more positive note, I should be able to do this with my eyes closed now, how nice.

    dont feel to bad, i replaced aperfectly good transfer case 3 times in 2 days, after my rear end locked, only to find out that it was my transmission that was fried (989.00), and had to be rebuilt. i bought a used case from a buddy, and replaced it only to have the same problem, so he brought me over another case, and i replaced again. you can save a ton on labor cost's, but only if you know what is wrong. i have decided that from now on if i am not positive of the problem, i am taking the truck to the dealer, and paying 75.00 and let them do a diagnostic check. then i will make the repair myself.

    Edelbrock, and quite a few other companies recommend you don't use the little rubber gaskets for the front and rear of the manifold. They recommend useing a thick bead of RTV instead. I just replaced my stock manifold with an Edelbrock and no leaks so far. I also almost put the Permatorque gasket on instead of the Printoseal one. I guess when the package says "READ ALL DIRECTIONS PRIOR TO INSTALLATION" we'll listen. Good luck.

  8. make sure your oil sending unit is good too! mine leaked right out of the sending unit itself, not the fittings. at idle it would bearly drip but of course when i drove it and the oil pressure went up it made a big ol' mess.

    Well, here's my dilema, everything is off and ready to go pn tomorrow, I noticed the warning about permatorque gaskets and I can't find the printoseal ones around anywhere. Think I'll be okay to just use the permatorque ones? Also, I'm considering using the endseals along with RTV, any objections to that. I'm afraid of messing this up again with the RTV, so I figure how bad can those end seals be? ZTHey have tabs to hold them on. Two of my friends have put on alum intakes with them and no problems to date. I'd liek some input before I go at this again. I'd hate to have to do this a third time!

    I don't know the differance between the two gasket sets but if you use the rubber end seals and RTV the gaskets will push out and won't seal. Use the Permatex high temp (orange), clean all surfaces with carb cleaner on a rag just before installation and use a thick beed (slightly more to the outside edge). Stuff some paper towels in the head and intake openings and give all surfaces a thin spray of Permatex High Tack. I almost never have a leak when I do the work myself.
    As for the sending unit, REPLACE IT unless you like the sound of a motor when it blows! Good Luck! I'm not kidding, get some High Tack. you can also run a small bead of RTV on the outside of the manifold after installation as an extra precaution.

    I found my printoseal at a speed shop. You might want to try that. Edelbrock specifically mentions that for a reason. If you want to be 100% sure on you intake not leaking you might want to go with the printoseal. As far as the end gaskets it's your call. The RTV makes for a pretty slippery surface on rubber. You might think everything is on right, but can you see the gasket at the back of the motor? Again Edelbrock takes the time to mention this for a reason.
    If you cant't find the printoeal locally. maybe turn to summit or jeg's. You have everything off and clean. Do it right and do it once. Your blazer might be down a couple more days but it sure beats another disassembly.
    Again good luck

    Hey BUSH, call Hermitage autoparts if they dont have it they can get it for you. IF not call Tennessee speed sport, then Napa on Nolensville rd for the Printoseal gasket that is.

    I got mine at Summit Racing when I needed them, and they shipped fairly fast too.
