  • 91-95 Plenum Removal

    91-95 Plenum Removal

    I did this on a 94-95 engine but aside from a few minor vacuum lines the instructions should work. 1. remove the plastic engine cover 2. unbolt the plenum to lower intake 10mm bolts 3. take the 2 rear mount nuts off, they are on the rear of the plenum by the spark plug wires 4. take the intake arm/tube and airbox/cone filter off 5. unhook the cables from the throttle body. It is easiest if you slide the plastic clips off of the metal mount. 6. take the 2 small screws holding t...

  • Oil Pump Drive Quick Fix

    Oil Pump Drive Quick Fix

    I have done this myself it was fairly easy it took about 6 hours, but I was in no way hurrying. 1. Remove the air filter elements. (Use a flat head screwdriver) 2. Remove the plenum. (You will need a 10mm and 13mm socket, and a pair of vice grips.) 3. Remove the 4 bolts holding down the fuel rail, remove the thin metal rail running along the top of the fuel line. Pull up and the injectors should simply pop out. 4. Remove all electrical connectors on the harness for the fuel rail, (3 by the ...

    Cam timing text walkthrough

    If you do not have the cam hold down tools, Go here to make your own. Take o*nly front valve cover off. Remove the front plug wires and the four bolts across center and o*ne for the plug wire retainer. Next find a bolt that will thread into the hole between the cam lobes at the far left. This bolt will be 2.5 inches by 7/16 in. I think. Put the valve cover back o*n to drive to the store to get some bolts if needed. If not remove the oil from the threaded hole first before threading a bolt in. When...

    Cam Timing Picture Walkthrough

    The following pictures and directions should be used as a general guideline and in no way represents every year/modification. I will have a page of all the motor torque specs soon.

    Parts
    You will want to replace EVERYTHING when you replace the belt. It costs more now but it will save you time and more money later on.

    The specs for my home made tools = 1/2" x 1/2" x 6" key stock with 5/16" hole in center. Bolts are M8 x 1.25 x 50mm, two washers are needed on each. Sorry about the dark pics, flash was not working for some reason.

  • LQ1 Service Bulletin 57-61-09 Lifter tick (cold)
    by Schurkey
    Dug up the GM Service Bulletin for "Lifter tick when cold", 57-61-09. '91 to '95 LQ1 (VIN X)

    http://mymonte.com/discussion/topic/...e-%2357-61-09/ The parts kit has been discontinued by GM long ago. My quest was to find sources for those parts; and complete the procedure on my '93 Lumina Euro 3.4 which was torn apart to replace the rear head gasket. There are three critical part numbers in the GM service kit (aside from gaskets and O-rings) required t...

  • 3.4 DOHC Heads on a 3x00 Block
    by bszopi
    Several people have talked about the possibility to use the 3.4 DOHC heads on the 3x00 engines. Some for performance, and some for replacment, where getting a 3.4 DOHC block might be difficult, but getting a 3400 (or even a 3100) block might be easier to come by. For these test fittings, I used a 1994 3.4 DOHC BLOCK, a 1994 3.4 DOHC REAR head, a 1999 3100 SFI BLOCK, and a 1996 3100 SFI head. This article is broken into 3 sections. The first section is BASIC COMPARISONS where I compare the BLOCK o...

  • OBD2 Tuning 3.4 DOHC
    by Dave96z34
    The 97 4T65 in the Monte Carlo is almost bullet proof. I have been beating the crap out of my reman with my blower now for 2.5 years of daily driving vs the 60 NA that I couldn't get 1 year out of. 4 Trans in 50K miles. I'm a violent offender. Overfilling and royal purple atf are my secret. DHP will do 96 and 97 DOHC tuning, HPTuners only works with the 97 computer. 96 can not change line pressure, 97 can. 97 bin is double in size of the 96 bin. They changed every thing and it has every ...

  • 3.4 DOHC Pistons
    by SappySE107
    Here is the TRW catalogue spec sheet for the 91-95 as well as the 96/97 pistons.

    TRW 3.4 DOHC Pistons
    Silvolite 3.4 DOHC Pistons Notice that the 96-97 pistons don't have as much compression distance but also have a dome to them. I dont know the exact amount of compression loss you will get when using these pistons with the 91-95 heads, but it goes against the common belief that 96 pistons raise compression. The Silvolite pistons are the EXACT pistons used in the 91-
