valve lash.

[riceburner]

ok so i rebuilt my engine and now have valve lash. it sounds like its only on a few of them. mostly rear bank. but how do i go about fixing? what could be wrong. i know i forgot to stick a q-tip down in the bolt holes prior to reinstall ....could they have not torqued properly?

[Bio248]

you didnt stick q-tips in? they might not be torqued properly (the rockers).

[riceburner]

no i didnt........i guess i will get in there a re-torque them tonight see if it fixes itself.

[Bio248]

i do not know what valve lash is, by the way.

[riceburner]

valve lash is just a fancy way of saying the rockers are ticking...makes selling jobs easier for mechanics like myself

You should only have to adjust valve lash on a solid roller. There is no adjustability on a hyd roller cam and valvetrain.


The only thing that could be wrong is that the rockers were not torqued properly,You're push rods are the wrong length or you have a colapsed lifter. If I recall correctly you are suppose to soak the lifters in oil while they are out of the engine.

[riceburner]

well, i went thru and cleaned out oll the sleves and re-torqued them. sounds good but found out i have an exhaust leak. could this be some of the ticking?...and i also broke the lower coolant elbow tongiht as well.....

[UR LOSN]

yes, an exhaust leak up by the exhaust manifolds will cause a ticking noise...

[Bio248]

yup. pre-o2 exhaust leaks are nasty.
