Engine Broke :(

[mark01348]

Hi guys,

As you probably know from my recent topic my Tsport has been suffering with a lack of power. Today I took the rocker cover off to find the lift rocker arm of number 3 cylinder intake valve has snapped off. Unfortunately I cannot find the broken piece of metal, it doesn't sound like it has been rattling in the cylinder so I'm hoping to find it sat in the oil sump.

The only issue I have is the shim is missing off the top of the valve and I don't know what shim to order, there are 41 different sizes to choose from but I cannot measure what one I need because there isn't one.

Any advice?

Thanks

the 2ZZ uses a shimless bucket so unless the bucket has dissapeared youre ok. hope you find the other bit of rocker arm

Hi,

The little caps that sit on the top of the valve are different thicknesses enabling you to adjust the valve clearence. Luckily I found it sitting in the head. Still unable to find the massive piece missing from the rocker. Very dissapointed in the engine I must say. Just hope I find the metal in the sump and not in the cylinder.

I checked all the valve clearences and they were good so hopefully its a straight replace cams and rockers. I hope that piece didn't snap because the valve was stuck or something.

I just realised that the picture I took in August when I changed the lift bolts the bit of rocker is missing. Oh dear, it has been like this for ages and I've been driving :( Not good

help lol

see damage in pic: large piece of rocker is missing. Wonder if it snapped because the valve stuck or something?
