Help Needed Please!

Hey Guys,

We have just been tryna fix my flatmates leagcy as the crank pulley had been put on wrong by someone and was wiggling like hell, due to this it had wreked the the keyway on the pulley, and the little D shape key that sits in the crank was mangeled. The only way to remove the key so that we could replace it was to take the cambelt off so that the sprocket on the crank could be removed, reveling the mangled D shaped key.

Now this all went smoothly and put the new key inplace, but we didnt lock the cams......(i no this is dumb and I know for next time!!!)

when we were fitting the cambelt back on the cams slipped!!!... but not to the extent that I would have thought it would have bent the valves? are they easliy bent??

But anyways we have checked the timing over and over and im certan that it is all fine, but when you wind the motor over and try to start it it sounds like the timing is out! And it wont start. Have we bent the valves?? and if so do you have to pull the motor out to replace the bent valves?

Any help would be great guys

Thanks

i wouldnt have thought that would be enough to bend the valves, i did a cambelt recently on a TT BG5A and used a rangi setup to hold the camshafts(ring spanners with cable tied to each end, tied to the engine and body) possible one camshaft is out by one tooth..thats all it take to make it run like shit.

You know for next time to mark everthing to shiat then take off cambelt ;D

did you line the double lines up in the middle and the single lines up on the outside with the cover... also the crank pulley doesnt line up tdc its about 2oclock if i remember rightly... check by putting the centre cover and pulley on...

hey yea 2 top cams moved frm 12 to about 3 o clock was trying to move more but caught it an moved bak, is there a way to tell if the valves are bent ??

cheers

search and learn what a leak down test is, a basic compression test could also tell you but it may not be a good idea cranking it over too much considering what you have been saying. Good luck

i can almost garuntee it hasnt bent valves.. just time it up and turn over at crank pulley twice as cams turn at half crank speed and feel for four compressions...
