Timing belt broke on 97 gs spyder

[Theorem]

Hello,

Yesterday, the timing belt on my sister 97 gs spyder broke while she was driving, and i have a few questions regarding to possible damages that could have caused to the engine.

It's a SOHC:
1. Do i need to purchase a rebuild/new head due to possible valves damage and how do i check/know if the valves are bended or not?
2. I live in Lakewood, Could anyone recommend me some reliable and reputable shops in the area that i could bring the car to if my sister decided to fix it.
3. What is the possible price range for the fix so i can let her knows.

Many Thanks
V

You shouldnt need a new head, at worst a new set of valves and some machine work and away you go. Im not even sure (I cant remember and cant find my manual) if the SOHC motors are interference or not. My recollections says they are.

We would be glad to help you :) Feel free to give us a call and I will get a quote together for you.

Cheers,
Don

Going back to a "moment" of mine. I seem to remember *trying to start a 1.8l and the timing belt was way off. ( note: never trust someone who says they've done it before) we (I) had no problems fixing the timing, and getting the car running again.

I have a lot of experience with your engine. Rebuilt a few too. The head will be $400 to rebuild, plus R&I labor plus timing parts, etc. Oh, and it will be done correctly with all of the proper 4G64 parts. 719-243-5305

That's a 2.4L SOHC motor not a 1.8L the 2g eclipses never came with a 1.8L motor.

That's correct 2.4L SOHC

Hello All,

Thanks for all your replies

I have a question, can i perform the leakdown test without the timing belt attaches to the engine. The reason i ask this question is because i want to know whether the 2.4L N/T has any bent valves or not ?


Thanks

Yes, you dont need to turn the engine over to do a leakdown test. Make sure the valves are closed though, you might want to pull the cams.

Cam. Singular. SOHC. :)

If you want to borrow a leak down tester, give me a PM.

How do i know whether the valves are closed or not. Right now the cam doesn't align with the marking. I took the valve cover.

Easy, you remove the cam (singular, whoops!). I wouldn't try and screw around with rotating the engine if taking the cam out is the easiest option... that said I don't know if for some magic reason it's actually really difficult to do that on the sohc motors or not but I really doubt it.

[D Walker]

taking the cam out is NOT the way to do it. you HAVE to rotate the engine to exactly TDC for each cylinder or when you hit it with air its going to spin around. I have a TDC indicator I use to determine TDC, but if you are careful and pay attention to what your doing you can use a phillps screwdriver with a bit of tape over the tip.

[Cloud]

OR, you can just block the engine so it wont spin. If the timing is off then it isn't really a guarantee that the valves will be closed at tdc either. I have had interesting leakdown results based on where in the cylinder the piston is though. I suppose this might be due to a block that isnt torque plate honed/bored or just worn unevenly.

[JackM]

Agreed, TDC doesn't work in these cars. We will have it just past TDC right after it would fire on that cylinder. We use a breaker bar on the subframe to hold the engine still. My brother will sometimes hold the bar, but you need to be careful not to bust your fingers.
