I...WARNING: It's not just your intake gaskets!<br /><br />I'm the owner of a 94 Camaro with the 3.4 V6 that I just restored. Both the 3.1 and 3.4 have the same type of heads which use the intake manifold to complete the valve cover, gasket surface.<br /><br />When you remove the valve covers, you'll notice that the aforementioned surfaces are not equal in height. The intake surface will be lower than that of the head. The reason for this is because the intake bolts go "straight down" into the head, resulting in a "wedge effect" which will drive both heads downward and away from the intake's mating surface over time with expansion and contraction. The intake bolts are not directed at a right angle towards the head's intake surface(as they should be and had been for decades for this very reason).<br /><br />When you remove your heads (which you will), remove and take a close look at the four, metal dowels that hold them in place. You'll not only see thread marks within them from the head bolt, you'll see that they are distorted from being sheared between the block and heads. I recommend that you not only replace them, but find some that are beefier to help prevent the problem. The factory dowels are quite thin and must be replaced; along with the head bolts that stretch upon torque and are useless thereafter. Clean your block threads with a tap, too.<br /><br />Be sure to check all lifters to make sure none are flat. "KEEP THEM IN THE BLOCK, AS TO PREVENT MIXING THEM UP." I disassembled each of mine, using a bent coat hanger, plyers, and a copper gun cleaner brush to remove the residue within that causes collapse, and a dab of assembly lube on the lobe surface upon reinstalling each one. Upon finishing this task, which assures no collapsed lifters and proper starting height for valve adjustment, tighten the rocker nut while moving the pushrod "up and down" until it just barely can't be moved up and down anymore without depressing the lifter plunger. Don't do the twisting method; that's mindless and stupid. Just find the correct valve to crank position procedure and follow my advice. Also make sure to tighten the rocker nut "one full turn" after removing the aforementioned lash. You'll find that most books say 3/4 to 1 1/2 turns, as if valve clearance bears no relevance, lol. Idiots. I've been working on Chevy's since the 70's, and one full turn has always been the standard... worked for me.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7800472412232339087.post-6603440775637518572018-04-04T11:24:37.528-07:002018-04-04T11:24:37.528-07:00Thanks!

A note to others: be careful when prying up the fuel rails, on my engine an injector retaining clip broke before any injectors pulled out of the manifold. Disengaged the clips first, then popped the rails off the injectors. To remove each injector, pried up gently from the bottom while rocking the injector back and forth. It will slowly work its way out.<br />Again, thanks for the massive effort it must be to make these posts/videos...Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7800472412232339087.post-47691534451415242792018-02-09T16:02:51.930-08:002018-02-09T16:02:51.930-08:00Thank you for posting ,about to do this on my 2000...Thank you for posting ,about to do this on my 2000 alero Anonymoushttps://www.blogger.com/profile/17519316624408707987noreply@blogger.comtag:blogger.com,1999:blog-7800472412232339087.post-73873607362897107132017-07-21T10:04:19.573-07:002017-07-21T10:04:19.573-07:00Please continue this great work and I look forward...Please continue this great work and I look forward to more of your awesome blog posts. <a href="https://www.robotvacuumarea.com/eufy-robovac-11/" rel="nofollow">robot vacuum reviews</a><br />AKONhttps://www.blogger.com/profile/05721945446767980951noreply@blogger.comtag:blogger.com,1999:blog-7800472412232339087.post-27744433166918775122017-05-27T02:18:58.502-07:002017-05-27T02:18:58.502-07:00Thanks for sharing the post.. parents are worlds b...Thanks for sharing the post.. parents are worlds best person in each lives of individual..they need or must succeed to sustain needs of the family. <a href="http://www.elreviews.com/best-robotic-vacuum-reviews/" rel="nofollow">http://www.elreviews.com</a><br />Masoodhttps://www.blogger.com/profile/04095015619118883200noreply@blogger.comtag:blogger.com,1999:blog-7800472412232339087.post-14071626475753043042017-04-20T18:25:09.692-07:002017-04-20T18:25:09.692-07:00I am about to embark on this jurny as my car is gi...I am about to embark on this jurny as my car is giving signs of a bad manifold gasket. I am really glad I found this site cause I need all the help I can get. I have the 3100 series 3 motor but its basically the same thing as this one. I also want to rebuild the tranny but that will be a project for the future. The car has 185k miles and runs great all but when idling. It misses and bucks along with a bad gas smell similar to a vaccume leak but all vaccume lines are fine.joshontechhttps://www.blogger.com/profile/13800499658453980309noreply@blogger.comtag:blogger.com,1999:blog-7800472412232339087.post-10332549806858431462017-01-07T14:41:08.324-08:002017-01-07T14:41:08.324-08:00You're welcome.
