    Re: Check out my Headgasket Job in the car!!!!

    I used a comealong hooked to the engine hook on the drivers side to the rad support, but to be clear, I used it only to hold the engine forward as far as I could pull it by hand. You have to be careful not to damage the motor mounts. Actually I only used it on reassembly. That 1/2" or so really made a difference when putting the heater pipes and valve cover on. There should be enough clearance on your 99 to remove the head without moving the engine, although it will be tight removing the valve cover.

    Re: Check out my Headgasket Job in the car!!!!

    I have been driving it almost daily, and have about 6000 miles on it. It's running great. Temperature holds to a max of about 205 going up hills. No issues at all. I bought a used timesert kit off of ebay, and then you can buy the inserts themselves from the manufacturer. I was planning on selling the kit when I was done, but so far I havent. I keep thinking I would pick up another car that needed the work for cheap.

    Re: Check out my Headgasket Job in the car!!!!

    update so far....thanks for the tip on the cradle bolts really gave me all the room u could need really (still is tight) and took out the 10 head bolts, unhooked sensor on head, took off sprockets. FYI there are 5 10MM bolts connecting the time tensioners and such connected to the block very tricky to get to, have to use a magnet to make sure u dont drop one into the bottom.
    Anybody got suggestions how to take off the 2 black pipes running from the water crossover to the heater core hoses do you have to take them off and if so how? nothing in the alldata manual and looks like the bracket is welded to the head
    Thanks alot

    the two brackets are held on by 1 (on each) 10MM? bolt I used a midget gear wrench, a swivel head ratchet may also be able to get in that tight area.

    Its alot easier to remove the pipes without the bracket in the way. It does bolt on, I left it off altogether, much easier to installer the pipes.

    Re: Check out my Headgasket Job in the car!!!!

    well almost got the rear head off but it still feel like something is holding it.
    Unhooked all the tensioner bolts (5 10MM), the sensor on the left and right, unbolted the water crossover, unbolted the rear flange to exhaust,unbolted the big black bracket with 2 nuts on the head and one bolt on the block>theirs one nut that is holding some electrical wires; does this need to come off as well? Besides last thing mentioned it should come off right? Any tidbits or pointers would be greatly appreciated and thanks alot for the help so far.

    Re: Check out my Headgasket Job in the car!!!!

    On the drivers side there is a bracket that goes from the head to the tranny. Did you disconnect that? Look at the base of where the engine lift point is.... On the passenger side there is an extension of the motor mount bracket that has 1 bolt hooking it to the back of the head... I can't think of any more right now.

    I wonder if some pics might help?







    Sorry I don't have anything really up close right now. I can get some tomorrow though.

    Re: Check out my Headgasket Job in the car!!!!

    ya man this is what i think is still holding the rear head because i can get it way looser on the right side, was wondering if u had a pic of the opposite u just posted. For the other black bracket there is a nut with wires connected to it. Dont knw if its connected to the head or the black bracket thats connected to the head and block(2 nuts on head one bolt in block)
    I think what u posted is what was holding the left side down.
    will post more tommorow night hopefully with no rear head.

    The bolt for that tensioner was supposed to be screwed into the head.... Check to see if if sheared off. Hopefully it didn't fall into the engine. Stick a magnet-on-a-stick down in there to see if you get anything.

    Re: Check out my Headgasket Job in the car!!!!

    I remember those ground wires when I did mine. I had a slim wrench that I managed to hold the back nut with, because the whole stud was turning on me, and I didnt want to break the wires. I did spend some time on that. Hard to tell by the pics, but all I had was one this spot that was steam cleaned between #1 and #3 cylinders. Thats all it took.
