July 11, 200619 yr Well.....after running 5 qts of diesel fuel through my '86 brat (ea81) to try and "un-gunk" my hydro lifters, (with no problems BTW) I decided that something was definitely amiss when it was STILL clacking and running on 3 cyls. Sooooo, I pull the valve cover, and fondle all the pushrods (sounds so dirty) And look what we have here! -OUCH!- Four minutes later (literally) and with donor pushrod already installed .....she's runnin like its 1986 again!!!
July 11, 200619 yr You don't have hydro lifters - that is a solid lifter pushrod. Hydro's are steel, solid are aluminium with steel caps. GD

July 11, 200619 yr Author As near as I can figure, that particular valve fell way out of adjustment, and the end of it slapped into the end of the adjuster cup. Once it had even a slight bend to it, Im sure it was all over with for the high RPMs these motors see in a typical day. Im just guessing here.....correct me if Im wrong.
July 11, 200619 yr not all hydros came with the one piece pushrods. Really? Interesting - all the ones I've taken apart had them.... I'll have to look under the valve covers on the one I put in the wagon - it's an 83 block I think. You know when they started? GD
