Hey guys,
So I took my car to the dealer to get an alignment. when I get a call saying the T belt tore during the test drive. I was mad but I had them put a new one on. But then the valve in the no. one cylinder is bent or smething because it has no compression. They wanted 1600.00 to fix it. I drove it home slow, @ 2 miles home.
I don't know if the piston can get damaged or if anything else can happen besides a bent valve when a t belt snaps And now I'm looking for the best solution to fix it. I use it for school and it's my only car so I need something reliable. I appreciate any input. My car is a 91 crx w/ sohc zc

Oh, and I'm tight on cash since I the alignment was my last thing on my to do list after replacing all my suspension related components.

Here are my options so far
Fix current head @ 600.00 -700.00
Head from hmotors w/o cam 100.00 plus s/h plus @ 200 labor
I'm waiting for a call from hmotors if they found a complete head, don't know price labor @ 200.00
MOtor from hmotors 600.00 plus 400 labor
I really just want to do the hmotors head but I don't know if anything in the block was hurt. Can sometthing happen to the internals in the block from a t belt snapping?
ThankS.

The bent valve can hit the top of the piston. If you where able to drive it home it might be ok. The only way to really know is to pull the head though.

Oh, I removed the sparkplug and it looks good, no scrathes on the top of the pistons just a bunch of black stuff that was there when I did the head gasket
I'm guessing if the valve is bent it did hit the top of the piston but I don't see any mark on it
the tech told me the no 1 cylinder is leaking 85% so I guess it's pretty messed.
I'll pull the other plus ad see whats the deal. I was told nothing happens to the pistons because they're stronger than the valves.
What else besides the valves and pistons can be damaged though?

acmoc

What do I need to do the head?
Head gasket manifold gaskets Anything else
Do I need a new timing belt or can I still use the Honda one it's only a day old? 5 miles on it. Shop manual says I can't use it?
Do I need new head bolts?
Should I be driving it more O have the mechanic do it at my home?

1. you most likely will have to have it machined(if it isnt too badly damaged)
2. those gaskets, valve cover gasket and all of the right tools.( dont forget the new valve(s).)
3. you don't need a new belt if that one is brand new and in good condition.
4. since you said you had the head off before to change a gasket im going say yes, because they have been torqued so much already.
5. dont drive it. your just going to **** it up more. tow it to the mechanic or have him come over.

also, i dont think its worth 1600$ to fix it. you can get a complete head for less then that.

as far as the pistons go, we've had several motors come through our shop with broken timing belts and usually when the valves contact the pistons they leave a small mark but nothing major. You should be good just fixing/replacing the head. Good luck

If it's a new belt how did the belt tear? They aren't culpable for anything? Was the belt slapping/lose before? How did they get it to skip time if they were just driving it to the alignment rack and back...

fishy?

No you don't. Go buy a torque wrench. A head swap is cake man. Follow the instructions in a manual or look up a DIY write up. Save yourself the cost of labor. You'll learn a lot in the process. A good trick to use to avoid having to mess with the timing belt is to set the engine to TDC before taking it apart. As you take the cam off, tilt it and slip the belt off. When you put the new head on, simply use that same trick, line up the cam, tilt it, slip the belt back on and bolt the rocker assembly back down. It will save you a ton of time. I do it all the time with B and D series motors.

Yea but the head i bought has no camshaft, I have to use mine. And I don't know how to do the valve job after. Plus, the land lord told me I can't do any more work on my car any more ( spilt allot of oil before)
But yea, I know it's only like a 4- 5 hor weakend project

theineffable

i don't get it...the dealer claims your timing belt tore? if so, how did you manage to drive home w/out replacing the belt first? are you sure they aren't just screwing you?

They put a new belt on for him, he said.

For future reference you can just buy a $10 valve, watch a video on home valve lapping and seat it in with valve grinding compound by hand or my method spinning it with a drill and a rubber hose. Then there is only 1 valve to adjust. With all the info out there a head swap is not to bad to do. Having no where to do it is a problem. The dealer driving your car and it breaking I agree with a previous posting " fishy " . The price for a head, well not to bad, coulda been worse. Hmotors, used head? Have it surfaced if it is used, just my 2 cents as a insurance policy for your new head gasket.

As far as what else. You never know until you pull is " most " of the time no piston damage, no head damage, no collateral damage. As far as the 5 mile timing belt USE IT!

oooohh, that sucks. good luck man. See if anyone local to you on here is willing to help, but deff resurface it like rwhsohcef and others suggested. It should only cost like $30.

I got my head today but I ran into another problem; the head on my Sohc zc reads "pm3-6" and the head Hmotors semt me reads "pm3-5". I tested all the gaskets on it and they all work but they're labeled for both 1.5 and 1.6. 1988-1995
Does anyone know if these two heads are the same?
The only difference I see in them is that on the pm3-5 head the port for the carbureated fuel pump is sealed off and on my pm3-6 head it has a block off plate on it
Does the 1.5 an 1.6 use the same head?

thats messed up that they thrashed your timing belt i bet they were out having a little fun in it... hard to believe it snapped right when you were at the dealer.

acmoc

Exactly what I thought.
It's all aftermarket so they probably got a lil fast and furious with it

acmoc

It's smoking a lot, this normal for bent valves?
I have the Hmotors head, going to have it machined and all then put it on, a friend is gonna help me for only 80.00 bucks.
I have to use my old cam, do I have to do all the valve clearances again?
Can someone give me a link to how to do it?

my question is, why were they going to charge you something for what they broke? did you sign any paper work stating that what ever happens to your car at this shop is your fault, and responsibility (WTF)?????

you should have used that money you bought for the head on a lawyer instead.
