Ok been chasing water leaks and the newest one is behind the water pump, i pulled the pump and where the pump pushes water through the timing chain cover is leaking,i think that's what it is, and i think it'll just be a gasket to replace, am i right and any advice, thanks
 
cool thanks for that, i'll hopefully do it tommorow, for now i'm just getting it running so i can drive it again, it's been sitting for like 3 years once this is done i''m gonna get all the little stuff done, then i'm gonna work on a drive train swap,
 
its tough to replace the gasket with the harmonic balancer on there- and make sure you dont over tighten the bolts when you put the pump and timing cover back on- i made that mistake and it leaked even more then it had before
 
lol oh yah i wonder how i missed that. drain the block of antifreeze aswell. Remove the harmonic balancer and all those acc on the front of the engine. you will probably have to pull the rad to get a puller on the balancer. Oh yah just so you don't do what i did first time i pulled a balabcer. Make sure when you pull out the bolt that holds it on the crank that you get the huge washer out aswell. it is kinda hard to pull it off it you are pushing on the washer at the same time.
 
i got all the bolts out of the timing chain cover and got it loose, and it'll not come off, i got under the car and looked and the timing cover goes around the balancer, so i HAVE to pull it to get it off, i tried to pull the pully on the balancer and the engine turned, how do i get the pully and balancer off? help,
 
as far as the 4 bolts that hold the pulley on the balance you are just gong to have to hold the engine frome turning over. maybe keep it in gear? or us a impact gun. it will spin quicker and take the bolts out without engine turning over. i think i usally get the longest flex bar i have and move it rally quick. a quick jerk usally loosens the bolts then you can just use a rachet to do the rest.
 
the pulley on the balancer has four bolts holding it to the balancer- those should come off pretty easily. the balancer is attached to the crank shaft by a 15/16" bolt that you need an impact gun to get off. it cranks out the normal way, you just may hafta pound away at it for a minute or two until you can break it loose. then you need a harmonic balancer pulley puller to get the balancer off. the easiest way to get that off it to thread the 15/16 bolt into the hole a few turns then let the puller push off of that. then when u get it loose take the bolt out all the way
 
ok i got the bolt out , and the washer, as best as i can tell the pully and the balancer are one part, i'm gonna get a puller tommorow, how to i check to see if my timing chain, and timing and all that is in the right place, i've always had a backfire when i decelerate"sp" and i thought this might be it, i'll post tommorow
 
ok, after i found the 4 bolts you told me about and got a puller and i got it out, but i the corner of my timing cover broke off, so i gotta get a timing cover and then finish it. When i put the cover back on do i use gasket sealer or just the gasket, i know i need it for the water pump.also i'd like to see if my cam is a roller or a flat top, is there a easy way to do this due to the motor being open right now, thanks

Not unless you pulled the intake and the valve covers. Then you need to pull the lifters. Thats a whole lot of work to see what the cam is.
 
ok, i looked in the bottom drawer of the toolbox and guess what i found anyway, i'm gonna finish it all this weekend and hope for no leaks, i'll keep ya'll posted, thanks for the help
 
ok finaly got the time, got it done, only broke one bolt, got it fired up and all seamed ok, them i hear the dripps, go to look, find nothing, till i look at the back, friggin return fuel line popped or something, so i get to drop the tank befor i can see if all the seals hold, blast
 
ok back where i started after fixing fuel lines, it not starting for 2 days and breaking my flashlight it starts, it runs, it leaks, i think the waterpump is bad, so i'll replace that, thanks for the help guys, what was odd though, the waster would drip off the corner of the oilpan when it meets the timing cover and there was a drip from the waterpump, but when it got warm it would just flow off that corner, and i could not find the source, so i'm gonna change the water pump, what do you guys think? thanks
