Ref post 12 in this thread just to reiterate what was previously mentioned. Very cheap insurance to change those critical components. You already have it apart, now replace the mentioned components before reinstalling.

----- Yes, compared to many others, you have dodged a bullet indeed ------

Or just barrels and plungers ? Thx

You need to go play the lottery.... you have gotten VERY VERY lucky .. that pump head was built before may of 2013... it is that old.


REPLACE the tappets, plungers, and barrels/rollers ... a set of all 3 ... I.E.> all the guts above the pump crankshaft.

By taking it apart, you just saved your engine's life... and if one of the plungers is not moving freely ... then it was right on that very edge of cracking, flaking, etc.. and destroying the entire engine.

I am replacing part now, it looks like 1 tappet goes deeper than the other .both of them are locked on the pin so when i try to put back head pump with barrels and spring back to the pump it doesn't go all the way throughout because barrel and spring in the right side touch the tappet first before the left side barrels witch make a gap between the head pump assembly and the pump do i can just keep tightin bolts i am afraid to break the bolts t have attachedpictures showing what i have done
thx rawze
