Default Bent valves?

Alright so I got my timing belt/waterpump done, but the first time we finally got everything back on and together we tried to start it and it didnt. So we took everything apart again.

After taking it apart we figured out that the timing was completely jacked up. So we timed it correctly put everything back on and tried to start it. Failed again.

The only thing that I can think of is that we bent my valves so bad that it won't start, anyone else have some suggestions?

Is it cranking at all? Is it cranking but not starting? How much of your motor did you pull apart? Yeah, 0 compression doesn't sound too good

Zero compression is nothing more than a Nightmare.

Just a suggestion. Buy a whole new motor, and junk the one with bent or burnt valves.

I just recently had the same thing happen to me, I either bent them or burnt them to hell. Im guessing they were burnt, due to the fowel smell, that I wll never forget. Zero Comp across the board

Buying a new motor is retarded just for bent valves.

Have the head rebuilt or do it yourself and it will be just fine....there's nothing wrong with the rest of the engine just because some valves got bent.

Burning valves is apparently not what you think...it's not like they burn and make smoke and burning smells, they just don't sit against the head for long enough and they retain too much heat and slightly distort themselves.

95silverluder I would just take your head off and have a machine shop look at it.

What he said. Even if you don't have to replace all the valves, make sure the shop recuts the valve seats.

Nothing is wrong with it. By all means if you want to have the valves replaced go ahead.

But in My opnion, once you crack open that block, all your reliabity it came with goes out the window.

For a Toy car something that needs high maintence anyway, its okay, but for a daily driver, I wouldnt bother.

if you understand how and engine works, have a torque wrench with proper tooling, helms manual and replace gaskets as it states then there is no reason that the engine will not maintain the same reliability that it did from the factory.

i dont really have an opinion either way. Replace/rebuild....whatever. If you are going to replace the engine, i would atleast take the head off and assess the damage.

Haha, come on man It's not like re-sleeving the block or anything. Just follow the Helms manual and use OEM gaskets and a torque wrench and you'll be fine. I have changed my head gasket, had my head rebuilt, etc and the engine runs great.
