oil pump pully bolt

[Vancho]

has anyone ever had the oil pump pulley bolt come off on them? i changed out that seal as well as all seals on the plate and i put it all back together and started it, ran for about 15 min and i heard a klink.. turned it off and on the right of the cams the timing belt has major slack that wasnt there, i thought weird, took it all apart and the bolt literally fell off once i got the timing cover off, i thought i didnt tighten it last time, so i put tred lock on it, let it stay over night, put it together the next day, start it, went for a drive, about 10 miles, came home and same thing the belt had major slack on the right of the cam gears, so it didnt harm my head or valves, but its messed up, any one know why this is happening? or how i can make it stay on there? and i drove it really slow, breaking in the main and rod bearings, i am guessing if i stepped on it it would skip and good fight me, dont really want to be taking off the head and by the way its a 98 gst, auto tranny, and balance shafts removed

Only thing i could think of is the slack in the belt is causing to walk back and forth on th oil pum sprocket and maybe the harmonics or working it lose? Is it a new timing tensioner?

Is the bolt showing signs of wear? Is it stripped at all? Is the nut the correct size?

Nevermind it's just a bolt, my mistake.

wow, ok the NUT is the correct size, and its not messed up and same old tensioner that works good.

I have no clue . Its just wierd it still does it with loctite. Why was there skack on one side if the tensioner is still good?

Make sure your using red loctite and torque it down to 43 ftlbs.

i was using blue locktite, and i dont know, i tightened it to as much as i could with holding the pulley with pliers with the other hand, but i am about to go get some red locktite, but has this happened to anyone else before?

 

[6damian6]

put some pieces of wood on each side of the pulley and have some one else hold it down while you torque it down.

the wood is used so you don't deform the side of the pulley.
