low13 Posted November 25, 2012 Report Share Posted November 25, 2012 Ok I expect everyone to smile and laugh. My '97 Deville engine cover won't come off. The bolts turn and cover raises up the two near the firewall came out but the other two just spin and spin. Oh I can't wait to hear the suggestions. I'm ready to cut away at it. HELP!!!!

Cadillac Jim Posted November 25, 2012 Report Share Posted November 25, 2012 The front bolts seem to be stripped. Try pulling them out with a pair of pliers. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

rockfangd Posted November 25, 2012 Report Share Posted November 25, 2012 they are either stripped or the whole intake bolts came out which sucks because they wont pull out as they are held down by the fuel rail. Basically there is 2 studs on the front. They hold the intake, fuel rail, and cover down. Sometimes when the nuts are too tight it can loosen the studs from the intake. As for removing them I havent had any luck with easy removal once that happens. If you can hold onto the stud from underneath the cover you may be able to get the nuts loose GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...

rockfangd Posted November 26, 2012 Report Share Posted November 26, 2012 I have an idea. sometimes it works. Tighten the nuts till they are tight. Hold consistent pressure down on the beauty cover and try to loosen the nut on one side. The pressure may hold enough on the stud to hold it tight. If it works repeat on the other side GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...

low13 Posted November 26, 2012 Author Report Share Posted November 26, 2012 rockfangd's Idea work. Tighten down all until the bolt came thru the top of the nut. Put some wd40 on the the nuts. Started with the front nut and vola the nut came off. Did same with the other front nut then back nuts. Changed spark plugs and wires. Will get new nuts but for now used the ones with the hole on top of the nut and tighten lightly. Thanks to everyone for the help and for ideas. Cheers!!!

rockfangd Posted November 27, 2012 Report Share Posted November 27, 2012 thats great but wow I dont know about tightening the nuts that tight. I would loosen and retorque the 2 studs to make sure you have not overtightened them GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
airmike Posted November 27, 2012 Report Share Posted November 27, 2012 the smallest spot of thread locker might help the studs stay. Link to comment Share on other sites More sharing options...
BodybyFisher Posted November 27, 2012 Report Share Posted November 27, 2012 Keep in mind that those studs hold the intake down, over tightening them as rock says is not advised you could damage the intake or the intake seals. If I recall, the torque is 13 ft lbs but check, it sounds like you may have torqued it way more than that. keep in mind that you are tightening into aluminum. mike gives a good suggestion with the thread locker.

low13 Posted November 27, 2012 Author Report Share Posted November 27, 2012 Great tip will remove the studs (the nuts are loose now) and will make sure to tourque to the spec. Going today to pick up new nuts. Runs great with the new plugs and wires. Again thanks to all for the ideas and suggestions. Link to comment Share on other sites More sharing options...
