Re: Problem with lash closing up
After checking all the components , we ran the engine of the dyno again . Ran well so once the engine cools down lash will be checked again .

Re: Problem with lash closing up
Ran into this with my bbc with titanium valves. The sealing surface of the valve began to erode causing the lash to close up a little over time.

So now, after all this grief , we checked the lash cold and lo and behold they all measure exactly what they were set at . Glad we checked everything , and don't regret being concerned , but all is well now . Thanks for all the ideas and comments . |

Re: Problem with lash closing up
So was the Lash off the first go round? Sounds like it.

Re: Problem with lash closing up
Best deal to verify and control accuracy of valve lash is from Precision Measurement Supply in San Antonio. Little valve gapper with dial indicator. Amazing how far off the "feeler" gauge method can be.
