    LQ1 Service Bulletin 57-61-09 Lifter tick (cold)

    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

    3.4 DOHC Heads on a 3x00 Block

    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

    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

    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-

  • 3.4 DOHC Valvetrain

    3.4 DOHC Valvetrain

    91-96 engines use a 35mm lifter, which are available in a lightweight design sold on the 60V6 store here. 97 went to the smaller diameter lifters so there are no options for them that I am aware of other than aftermarket stock replacements. 4.6 SOHC Ford springs (from a 97 thunderbird) will fit the 3.4 DOHC. They are a little stiffer and coil bind at a higher lift so a cam regrind will be tolerated more easily with them. You will need to use the 4.6 valve guide seals/seats, and pull the se...

    3.4 DOHC Camshafts

    Cam options for the 3.4 DOHC are few and far between. This is the most common reference given for regrinds.

    Steve Long Racing Cams INC.
    951-273-0816


    Cam Timing Because the cam gears are not keyed, the options for cam timing are nearly infinite. While this can cause a problem for the novice trying to set the cam timing, it also allows great flexibility for those with more experience. First, I must add that any painted timing marks are to be ignored....

    How to change the alternator

    Hopefully you know how to pull a rim off the hub. Here is the starting point for changing out the alternator.




    I think its a T-60 to get the bolts off the brakes. You need to pull the brakes off to have enough room.




    These are what the 2 bolts look like holding the front brakes o*n




    And the rotor with it.

    Get the brake out of the way. You can pull it completely but...
