Crimson Fury Z Posted November 29, 2005 Report Share Posted November 29, 2005 to continue the discussion(w/o the vs. posts). yes, get that dyno up, chop chop! mine does the cold start crap, but a few seconds over 2k rpm and its good to go. i dread to work on it because of the b.s. i go through each time(gaskets, the damn egr not wanting to go back into place...)and plus, its cold! need to replace the O2 and cts(coolant temp sensor) still. i will look into the lower intake gasket. been awhile since i went balls deep into the engine(actually Ben and John to be exact). is the lower intake under the plenum, or deeper? as far as driving, it runs and accels as good as a late 180,000mi engine does, and a +1 on the kidneys post. needs 2 new tires to smooth out the ride and i still have to use the can of gm tec, now that i got the new exhaust so it won't leak all up on the inside. i have test drove 2 other 3.4s, both close to 90,000mi and they were more responsive and smoother, but the brakes weren't that much better and my engine bay is/was a whole hell of a lot cleaner! the only problem is that the radiator has a pressure leak, if the cap is tight, it'll leak from the top driverside corner(haven't located the exact location), then if its loose, the leak is no more. i think i have had an overall reliable 3.4. all the fixes and problems have been everything but the engine and tranny. i'd be dumb and probably get another 3.4 if mine took a dump. theres just something about owning a 3.4 twin dual cam.

slick Posted November 29, 2005 Report Share Posted November 29, 2005 LIMG is not a hard task. Remove upper plenum, unbolt fuel rail from lower manifold, pop out injectors, unbolt lower intake, and wa-la. I know I'm missing a few steps in between, but not hard at all.

slick Posted November 29, 2005 Report Share Posted November 29, 2005 It's easier to do a lower intake manifold gasket on this car than the pushrods, FYI.....

White93z34 Posted November 29, 2005 Report Share Posted November 29, 2005 Prolly with the new ones having VVT and all that. Â what?? no 1991-1997 LQ1 had VVT period. Â i dono, everyone bitches and moans about the 3.4 being a pain in the ass to work on, personally i have no problem what so ever navigating the engine bay, i've had my intakes off probably 6 times or so for various reasons. but anymore its just a trivial task, and i rather like how the 3.4 goes together.

Â a fuckin men. if you think an LQ1 is hard 2 work on, go do a water pump on a toyota, a distibutor on a nissan, an egr on a ford, etc etc. I love working on the LQ1 because everything is so straight foward. the big issue with them is the alternator, and I moved mine so it takes 15 minutes to do. Â tell ya what, go do plugs on ANY 82+ camaro, takes 40 minutes to do on an LQ1/LH0 car, time yourself on a turd gen maro and see how long it takes.

gp90se Posted November 30, 2005 Report Share Posted November 30, 2005 pull the weatherstripping and rock the motor foward, rear plugs are simple. wanna take a pic of this homade plug tool. I cant see the #5, #7 and #8 plugs ever being easy. Quote Link to comment Share on other sites More sharing options...
fastbird232 Posted November 30, 2005 Report Share Posted November 30, 2005 I must have one of those freak engines where all I had to do was pull the weather stripping. NO pulling the plenum, NO rocking the engine forward. Just two extensions and a u-joint. Wa-la. Â My homemade tool was a coathanger I bent into a long hook to pull the plugs out. That was really the only tricky part. Quote Link to comment Share on other sites More sharing options...

Crimson Fury Z Posted November 30, 2005 Author Report Share Posted November 30, 2005 i pulled the stripping and cut notches out of the flap. i'll never get an import car, big $$ down the drain for shops, not easy to work on. Quote Link to comment Share on other sites More sharing options...

Guest TurboSedan Posted December 1, 2005 Report Share Posted December 1, 2005 i dont like u joints, only reason to rock the motor foward is to avoid using them  U-joints for changing spark plugs usually means you are asking for a cracked plug.

Farqineh Posted December 2, 2005 Report Share Posted December 2, 2005 Cracked plug OK if taking out.... Heres something I've used for years. Cut the end off an old set of spark plug wires (the boot) and a small length of wire. Use that to re-thread the spark plugs and then tighten. Toyota MPV, S10's, Lumina and Transport vans, I've never had to rock and engine to change spark bolts baby. Theres always a way. Inginuity! Mechanics good little buddy!!

Stevo Posted December 2, 2005 Report Share Posted December 2, 2005 It's just easy to crossthread the rear plugs if your not very careful. Thats the only thing I have to bitch about tranverse engines. Quote Link to comment Share on other sites More sharing options...
gp90se Posted December 2, 2005 Report Share Posted December 2, 2005 thats why you ALWAYS start the plug without a ratchet. on everything except the dohc motors, hold the plug and screw it in, then put the socket on and tighten it in. on a dohc motor, slide the plug down, put down the socket with extention, spin it so it starts, the put the ratchet on to finish.

Â OR.... Â Spend a couple bucks and buy a proper spark plug socket that holds the plug in the socket with an o ring. That way you don't have to struggle with lining up the plug with the hole, or pulling them out of the hole when removing them. Quote Link to comment Share on other sites More sharing options...
gp90se Posted December 3, 2005 Report Share Posted December 3, 2005 I don't like the rubber boots inside the plug. Since you need a good amount of pressure to get the plug end into the boot, theres a better chance of cracking the porcilin (sp). Quote Link to comment Share on other sites More sharing options...
