Consequences of breaking abalance shaft belt???

[dsm_dude12]

k so... what am i suppose to like the crank up with to se if its timed right? im reading in my hayne's manual that i have to line the 2 little marks on the top of the crankshaft pulley up with the t on the t-belt cover. and the 2 timming marks on the cam gears should be lined up if its in time. am i reading this right? or am i just an idiot?

the cams should look like - - that with the makes lined up and the crank pully line should like up the the T on the timing cover, or you could put a screwdriver in #1 cylinder where the sparkplug goes and watch it for top dead center and look where the cam marks are then

Not just the head, if it had been hitting the pistons you might as well consider buying a new set, you might as well just count on rebuilding the engine. When you get the head off make sure the dome of the pistons aren't damaged.

k. so i got the #1 piston to top dead centre. unfortunetly the cam pulleys timming marks looked off by a good 15 teeth. or how ever many degrees that is. so i guess im pullin the motor... good thing this dsm's in my hands or it just mighta been time for the junk yard. thanks for the help thoe guys!

ugh, i hate to bring this forum up again... but theres a thought in my head that maybe the valves are still good, and i really dont wanna take the motor out and apart then find out thats not the problem so anyways, the mechanic here told me to take out the plugs and turn the motor over to see if i could hear the pistons hiting the valves. so i did. and i dont hear a damb thing, the motor seems to crank freely. Could it be i got extremly lucky and all the valves are still good even thoe im pretty sure the timmings off a good 45 degrees and the belts still on turning the valves with the crank? this is really starting to bug me. also. if that is the problem. should it fire once i get the timming set up right without a balance shaft belt on or do i need the balance shaft belt on for it to run? i just dont get this and its starting to piss me off!! thanks once more

You could half ass it. Or you could play it safe and pull the head and see if there's any damage. You can spend money now, or spend more money later.

k. so at the moment. i have a plan, but im not sure if htis is gonna work. im gona adjust the timming so its correct and try and fire it up to see if the valves are bent. any objection's to that? and also.. do i need to have a balance shaft belt on or the balance shafts removed for it to fire up just to see if it runs right? I am really ansy to see if the valves are good but the b/s removal kits gonna take 3-5 weeks to get shipped, so it would be mighty good if it would run right without the b/s belt or then romoved!!

No the balance shaft will not stop it from firing or running for that matter. Why not do a comprssion test to see if valves are bent? Rather than say ok im gonna reset timing and turn it over to see what happens? If you insist in reseting timing im hoping you are turning it over by hand with a ratchet on the pully rather than the ignition.

ill try a compression test tommmorow hopefully if im not busy. i know this sounds really odd. but last time i checked the compression like 4 months ago it came up at 150, 150, 135, 80 and the car still pulled hard and beat several other talons, it didnt overheat and the oil stayed oil not milky mixtures of oil and anti freeze like a cracked head gasket would produce. it didnt blow oil out the exhaust either. so i unno but ill do the compression test hopefully tommorow and post the new results hopeing there the same as before.

[dsm_dude12]

k, so i ran a compression test today. it came up in all cyl's as 0. then i was freakin out wonderin how its completly 0 in all cyl's and my buddy said.. its cuse the timmings off, the valves are open at the wrong time. its making no pressure. im assuming he's right?

[blk_srt]

if you timing is actually off then yes and unless its off exactly 180* you've bent valves

[dsm_dude12]

thats the worst news ive heard all week.

[blk_srt]

Well it can be a few degrees off but if its like 15* off then you have a problem. If I was you I would retime the motor and do another compression test to see where I'm at
