Well it did right before my 2nd auto-x, yeah there was damage, I am pretty sure it bent a valve because I turned the engine over by hand and almost made it all the way through then it stopped at the very end. So know I have to pull the head and swap over to a head with 330k on it lol. Anyone have any tips or things to do while the head is off? Besides all the normal stuff (Timing belt, water pump and gaskets ) ?
um if you turned the bottom half of the engine with a valve open of course it's going to hit,strange because i had no problems with my dx when it broke a belt.Originally Posted by Ju_S12_Turbo

Oh, I forgot to add that part in lol. I Reinstall the timing (Yes I did it right) and it it hitting the valve and the spark plugs looked super cool, I'll post pics of that in a min
do you have it 180 degrees out? you line up the mark on the flywheel then there is a make on the cam gear, and it should say up, you can install that gear 180 out. thats really strange because i have the BS engine and i could drop a valve down to it's retainer before it hit the piston on tdc. I mean it broke the belt at like 7000 rpm and once the new belt was on,it started right up with no problems.

Really? hmm well here the pic
what did you do? even if the belt broke the pistons can't hit the plugs.
Lol damn!

No idea, car was running bad, turned it off. Came back about hour later went to go and start it and a few noises happened, then I pulled the plugs and they looked like that. So they can't hit huh? weird. But on the plus side The day before me and Strugglebucket were doming on the porsches and bmw's lol
Damn that sucks you didn't get to run on Sunday.
Are all the plugs like that or just two? You might have dropped some valves.

3 are like that and the one that wasn't is one I couldn't change lol. Hey if you have aim hit me up and I'll send you all the videos of you
when my rod exploded the pistion slapped tha fuck out of the head and it didnt bend the valves. it did knick the plug tho.

compression test the engine that will tell you.

not necessarily, he needs to do both a compression and a leak down to make sure the head is fine... motor can have good compression numbers but have a leaking/bent valve.

compression with a bent valve? have to explain that one further to me.

you'll notice a slight loss of compression within normal ranges, say in my case... i have a bent valve or two on my number 2 cylinder, yet my compression numbers are 192, 194, 182, 193
notice how it's within spec, it still indicates a problem but it's fairly common for this type of thing to occur.

hmmm mine was fine,
yeah i had a leakdown performed and it agreed with my thought of a bent valve, so that's how i came to the conclusion of having good compression but still having a bent valve.

Yay, even though my engine got hungry and nom nom nomed my spark plugs, put some new ones in reset the timing belt and it started right up. Now I just need to go and get a new T-belt
Edit I was wrong lol

alrighty, so after it has been sitting for quite some time (I hate winter in guerneville) I started to work on it. After buying a new timing belt and related things (water pump different seals and tensioner ) I got the marks lined up, but when I was checking the flywheel the only marks I found was 3 lines and the number 24 on the side of those marks. After searching it seems other people say there is a 15 and a arrow. Have I timed it on the wrong marks, I timed it in the middle of the marks. When I ran it threw by hand, there is no drag and it feels good. However, once it is started it hits (not like BLAM but you can hear a tick) the number 3 spark plug causing it to bend the grounding strap onto the tip of the Electrode. I have read and people say this is a non interference motor, but I am at a loss when it comes to this. think it could be massive piston play?
Piston hitting the spark plug is more than a timing issue.

haha I know that much, but what I am trying to understand is how that has happened. only thing I know for sure is that the ring are worn. but when I change my oil pan gasket there was no metal shavings and there was not excessive play in the caps
it took me a couple run threw to find the T on mine. i say give it a couple very slow turns. i cant see the sparks cause of phone. but what if they did that because of torqing when belt went?
Yea for photoshop...No license plate. :3

The marks for 15 degrees would be on a FI engine. The timing for carbed engines is more like 24 degrees. There should be another mark maybe 2-3 inches from the marks next to the 24.
However, this wouldn't explain the piston hitting the plug. Something is very wrong with this engine and you really need to pull the head and take a look. Otherwise it will keep happening.

we had a ZC once that the piston came up above the deck . it ran ok but something was wrong in the block, god knows what it was haha
Sure these are the right plugs?
