Bent Valves

[zoidbergmerc]

Hey Guys,

My Timing belt tensioner snapped and now all the valves are bent, the stems dont look that thick, I was thinking just Multigrips and bend them back?

Nah these are off my housemates R33 that I managed to break while I took it for a little squirt to the shops because my WRX was getting painted

Just thought I'd share the pics.

not too bad, new valves and you are back in business. Just find a stuffed second hand head with good valves.

Probably cost you about $300 (And the cost of valves) at a head re-conditioner. What are the tops of the pistons like?

[Dobz]

No deal! They've been weakened now they're bent and bending them back will make them even weaker.

Tiny little mark where the vavles hit, didn't even scratch it really, just cleaned it a little, so small it doesn't even come up in the photos.

lol @ bending them back - come on man...

You need to go buy new ones and then ensure they are all fitted correctly it.

If you are not doing the work yourself, its gonna get expensive.

Also as the pistsons have hit the valves, is there any score/marking on them?

The top right valve in the first photo (top left in second photo) looks like its actually snapped half way through.

PS- I'm sure your mate was stoked about that!

All new valve guides will be needed, you can see they are cracked

[toffy]

, buy new ones , check pistons etc , i wouldn't say they just lightly tapped the pistons looking at them .

guys, I'm pretty sure he's joking..... but 100% it will need new valves (it would be near impossible to bend them back correctly). and probably new valve guides and valve stem seals too. that is of course providing there's no piston damage etc.

bend them back, just be carefull with the exhaust valves as i think they are filled with sodium and that shit hurts if it gets in your eyes.

fill in the holes in the piston crowns with metal putty. As a bonus you can use a bit extra to raise the static compression if you have some left over.

Also goes relly well with tequila I hear

If it hit hard enough to bend the valves and crack the guides I'd be concerned not just with the head!!!! Contrary to what has been said, I'm not so sure it just lightly tapped the piston for that.

Reco head with new valves and guides.

Here are a few pics of mine when the same thing happened.

In this pic the valve snapped and was then punched into head

nice effort!

First I lol'd at the thread title and everyone in the office looked at me.

Then I spat my drink out laughing when I got to this part:

Im still recovering....

That's all I have to add.

he owns a WRX, that sounds like its been in a ding... My bets on he is serious

+1 to badhairdave, solution made of win!

haha good work. that is 2 dead motors due to siezed tensioners this week.

change them and their studs/bolts when you change the timing belt kiddies!

Ah, that must be where that old saying comes from "dont bend valves with your eyes"

Wait... what?

[JustinP]

You could try cutting the valve stems where they are bent, then sticky taping shaped pop sticks to replace whats missing. That should fix your problem, and add 15-20rwkw.
