I'd agree.....
and also agree on the pistons and valves.... very slim valves don't damage pistons when they contact, but you'll have to also see what else could be damaged.

 

Your valves are bent and the motor is out of time. When the piston comes up, it is hitting the valves because the timing of the cams and crank is off.

Depending on how hard the contact was, it can either mean a valvejob and replacing bent valves and possibly pistons as well.

We have an entire longblock available for sale we just listed for sale in the forums which may be your cheapest solution by the time you get done fixing everything.

 

most likely its just valves that are jacked. your pistons should be fine. no guaranteeing it.
so go ahead and call your closest head/machine shop to price the valve installation.
going to need.

new valves
timing belt
tensioner
head gasket
and hopefully not pistons as well

 

Hi COuld someone please help me im in a pickle right now.

I was driving down the road yesterday going 60 and all the sudden I heard a pop and my car stoped acclerating and so i coasted it to the side of the road. I tried to turn it on but it would just crank. The car can switch from park to neutral to drive etc. However, I took it to aamco yesterday and they got it to start and they said it might be an electrical problem but they still have to do more diagnostics. Has this happened to anyone and does anyone know what it could be?I thought it might be the tranny but I have no clue. Im just hoping it aint the tranny.

 

You blew a hose off.

 

Take spark plugs out and look in the holes with a flashlight.....you might be able to see pieces of a valve if they broke.....if they are bent, you gotta take the head off to look.

 

If I were you I would just pull the head off. Will take a few hours but worth it. If its just bent valves its not an awful thing to rebuild. I have rebuilt a few and its not rocket science. I did it on my kitchen table.. LOL. You just need a good machine shop to clean and redeck the head. Like everyone said once you pull the head you can see if the pistons are scored or damaged. If they are then thats a different story. Better crack open the wallet..

Good luck snap some pics and post them up I am sure everyone on here can tell you what needs to be done.

 

+1, exactly what happened

 

You said the tensioner caused the belt to slip, did you swap it out with the belt or reuse the old one?

 

ye you just a few bent valves.a compression test will give you a rough idea how many ar bent,u will defo have to tae the head off anyway

 

Thats a bad move if u did....i just did my 60K tune up and i replaced everything. After your rebuild i would put a HKS or Gates timing belt on there. Wont happen agian.

 

man i feel for ya. same thing happened to me.. tensioner went.
still rebuilding my motor. my head was completely trashed, not salvageable. bought a brand new stage 2 from slowboy racing. i had to bore the bloch .2 over due to all the scratches on the cylinder walls for valve peices.
its been expensive, if your short on cash i recomend just finding someone selling a complete motor.

good luck with the rebuild

 

No, a compression would cause even more damage. If you suspect the valves are bent, you should not crank the engine anymore.

 

After all this talk about how to fix the engine I think I would be getting the timing cover off for a look at the belts. If both belts look good and the tension feels about right I'd suggest turning the crank by hand enough to check if the crank and cam marks line up or not.

 

****ty deals, you'll see the damage once the head is off
