Help - 404 broken inlvet valve spring

1644 Views 5 Replies 4 Participants Last post by  esde

Made a rather disastrous discovery (given it's mogstock in 10 days!) today while doing valve clearances. We've got a broken valve spring. It's the outer one of an inlet valve.

I haven't fiddled with valves for 15 or more years, and all my memories involve taking the head off. Someone, please tell me this isn't the case.


PS - anyone got a spring kicking around? :)

Take out the spark plug, turn the engine to BDC for that cylinder, and jam a few feet of cotton cord into the hole. Then turn the engine to TDC untill you feel the cord start to get compressed, it will keep the valve from dropping into the cylinder. Much more reliable that the compressed air. Change your spring and pull out the cord, PRESTO!
Glad it worked for ya! Problem with using compressed air is it wont hold a valve thats worn, or if the seat is worn, or rings... etc, etc. Happy moggin!
