either the timing is off, or you bent valves on all of the cylinders. The latter is likely regardless to the former, unfortunately. Honda's almost never survive a broken belt

what happened is that the valves stopped but the engine didn't. The pistons slammed into the valves and bent/destroyed them.

If you're lucky you just need new valves in a rebuilt head. If you're not lucky, you need pistons, rods, valves, and a host of other stuff. Sorry for the bad news, but I think you'll find that its not pretty in there.

Well , dudes the head is off and no signs of holes in the pistons. I did notice on 1 of the cyl on the head that both intake & exhaust valves were open at the same time.

That is probably normal. The cam is designed with overlap. The intake valve is supposed to start opening before the exhaust valve completely shuts.

It doesn't take much bend to make a valve not seal. Its good to hear that things aren't completely munched. The last Honda I repaired we just ended up putting a rebuilt engine it was so bad.

hello before you go & put any $$ in the head.keep in mind that the valve job your going to need is going to seal the upper end of the engine.now with the miles on engine its going to put more stress on the lower end.you will probolly start seeing alot more oil usage being the rings ect. are all high mileage.its not always the case but some thing to expect.good luck

Might as well get a used engine . The top end is rebuilt , but the lower end is not.

I wouldn't pre-emptively put a motor in it.

if it ain't broke, dont' fix it!

honda's are some of the best engines out there. It might be tired, but that doesn't mean its *needed*

Well the shop found some worn out and damaged valves & some other stuff , so the head is getting rebuilt. Lesson to be learned , change the timing belt every 90/ 100k .

I wouldn't say that personally. For example the honda 2.4L has a chain, and they've been failing a decent amount.

Belts are simple, all you have to do is watch for oil leaks under the timing cover and replace them at the recommended intervals. Its pretty easy IMO

Hello

Sounds like you lucked out with only a valve job! What do the cylinders look like? Is there a ridge on the top of the cylinder? I'm betting that there isn't a ridge and the cylinders still have the factory crosshatching marks in them.

How was it doing on oil before the belt broke? How many miles were on that belt?

Regards

Dan

DanHey Dan,
Are you talking about the tops of the pistons ? If so , i notice some little dent marks from the valves.If you are talking about the cylinder walls , i havent looked at that closely.The oil was fine , didnt notice to much oil consumption. The t. belt had 260 k miles on it .

It should of been done @ 90/105 k.Well lesson to be learned. Got the head back from the shop w/ replaced intake & exhaust valves.Got done tonight and fired up the car. It ran !!!!!!!!! So dont wait til 260k to do the 1st timing belt . Do it at every 90/105 k miles . Also change the h2o pump and tensioner to .

You could shorten that up a bit "follow the maintenance suggestions in the manual"

There's plenty other things that if ignored will cause traumatic failures.

Most honda timing belts break between 140-160K, that I've done anyway. Did 3 of them just last couple weeks.
