so its been nearly 5 weeks now since i changed the clutch, but heres the shortened story:

clutch blows up, i drive it into my friends garage to change it out, we drop the trans and change the clutch, put it back together and it wont start, the motor is turning but not starting, and its also only building 90 psi of compression (should be 235 or so, ls/vtec motor). so i take the harness off to have a guy i know look at it, he dicks me over and doesnt fix it and wastes 2 week of my time . I finally get fed up and take the harness back from him and drop my car off at a shop. i get a call yesterday from the shop, he says he put the new harness in with stock injectors and it still woudln't start. he checked compression and he said i was right, it wouldnt build more than 90 psi of compression.

he tells me my intake shaft has SOMEHOW (WTf?) jumped 180 degrees of time and bent some valves (HOW?). i expletiveing drove the car into the garage, changed the clutch and now it has bent valves. whats your guys' input?

 

Did the timing belt jump on the gears??? This would cause all your problems....low compression, no start, no run. Check TDC and go from there. Once TDC is confirmed, do a lead down check. Start with the basics. Good luck.

 

what did you do to blow the clutch?? did you maybe drop it into the wrong gear and it revved allll the way up real quick??

 

You did not turn the engine backwards, did you? Sometimes, that can cause the timing to jump since it removes the slack on the front side of the belt.

Also, changing your harness will not raise your compression numbers. Compression numbers are directly related to the mechanical condition of your engine, not its electrical condition...

 

I've seen people ruin thrust bearing in the bottom end by using the tranny bolts to completely pull the tranny up on the engine without lining eveything up first, but I've never heard of bending valves JUST from doing a clutch job.

Mechanically they SHOULD be unrelated, but like RyanA stated if you turned the engine over backwards with a wrench in efforts to line the clutch up (really there'd be no need for this either if you have the alignment tool) then in [i]theory[i] it could just timing like he said.

BTW:

I re-read this and thought to myself:

"How in the hell does the intake cam JUMP 180 degrees out?"

Seriously I can see it jumping a tooth or two, but you are talking a complete half-turn!!!

 

Get your car back and spin you motor until it gets to tdc. When its there your cam marks shold line up. if they dont, you've jumped time and most likely bent valves. when you pull your head send it off for a pnp and put some cams in it and a tune!

 

alright this is what it looks like happened:

i put the dizzy in 180 off, it went in but didnt sit flush, when i tried starting the car the dizzy stopped the cam and the cam jumped almost 180 degrees (i saw it today and sure enough its almost 180 degrees off) on the timing belt, so now theres a good chance i have some bent valves. the shop is charging way too much and wants $80-$90 to reset the cam to normal time and do another compression check. I have a friend who owns a shop and is gonna help me out with this.

If a compression test shows 30psi after we reset the cam so its in time, then the valves are bent, but theres a light chance the valves arent bent, but the cam is out of time so its opening the intake valves durring the compression stroke, which would be the cause for such low compression. i will keep you guys updated.

 

Why did you leave out the distributor info to begin with?

...and why did you pull the distributor out to begin with? did you think the dizzy had to come out to do the clutch job, or what?

I'm becoming more confused as you add more info.

 

Doesn't seem like this is all of the story.

Clutch job requires nothing in the engine as far as I am concerned. Someone didn't do something right.

 

For real. Changing the clutch is cake and doesn't even call for the removal of the distributor. Kinda lost now haha.

 

it seems to me that the teeth on the dizzy would break off before it held the cam back. know this from experence lol at myself long story but the dizzy teeth broke off inside the cam groove. Just sent the dizzy back and got fixed. But I don't know I am with everybody else the clutch should have nothing to do with the cams????? Hope you get evrything fixed though.

My friend had a MSD pro billet dizzy on his si and one of the screws holding the rotor button on came out and the dizzy locked which busted/melted the cap. When this happened, the cam stopped and bound up causing the belt to jump teeth. His intake cam was about 90 degrees out of time. Lucky bastard didnt even get a single bent valve. Your belt just may have been too tight to let the engine jump teeth causing the dizzy to break. I would much rather have the dizzy tooth break than have the timing jump!!! You got lucky.

 

Man that **** happen to me once. Trying to take of and bamm my car died out. Cracked the cap and rotor, and the ignitor. Boy i was expletiveen mad, never trust your friends when working on a car. They careless because its not there car. lesson learn!

 

rofl!

 

 

shop re timed the cam back in time and 3 cylinders are fine, 1 has bent valves. they charged me $800 for a new harness, and labor to put the harness in, re time the cam and run the compression tests. Talk about raped!!

I picked the car up and drove it home, it drives but runs odd, deff loss of power and throttle reponse. Taking it to a friend whos hooking me up on the price, hes gonna take the head off and replace the bent valves for $400. the shop that already raped me wanted an extra $1k to do the same thing *thumbs down*.

Im just gonna sell the car now and take this whole swap as an expensive but valuable lesson learned.

Im lost.......why did you need a new harness? Sounds like a consentual "rape" if you paid for a new harness, which I dont even understand the reason for replacement.

Car always runs odd when you have bent valves. Does your friend own a machine shop? cuz if you have any bent valves you need machine work! So, chances are......you are paying a g less because it is not the same repair.

 

old harness was hacked to pieces, missing sensors and broken connections. also needed to get rid of the resistor box so i could change from the dsm 450cc injectors to some stock 240cc injectors.

 

If your valves are bent, Take it out your self. Bring the head and the new valve to the machine shop so they can look at it. If it is stock valves they go for around 25 bucks or so.

 

having a friend hook me up on a price, $400 to replace w/e valves are bent and not let it leave till its running flawlessly.

 

harness hacked up and missing sensors and broken wires? dizzy not put in right?

sounds like someone didnt want to think their mistakes was the cause of the problem, or the person who did those things to the car didnt have a clue they did it wrong in the first place, either way, it surely is an expensive lesson, but you shouldnt sell the car based on that.

We all learn from mistakes, how do you think some of these guys got so knowledgeable? Not everyone can be born with the 'badass' DNA like Jesse James &lt;/sarcasm&gt;

I think you are making yet another mistake by taking it to a friend because it is going to be cheaper. It seems that is how your car got in this shape in the first place....i.e. repairs the cheaper/easier way (not saying you did them). Remember that in order to do something correct, sometimes it is more expensive than you would like. The bent valve(s) may have caused damage to the valve guides meaning that you will need machine work done. Look into the repair and research similar repairs by others to decide if you think your friend should fix it the cheaper way. Keep us posted.
