Last night I did a cold adjustment. 1 turn past zero lash...
Fired up the truck today....every one was tapping...and wouldn't shut up......wtf....
all rockers acted normal...pumping like everyone says they should...Could barely tell they were even oiling without a flashlight and the obvious puddles on rocker arms flowing....great...but all tapping?
After it starts getting warm....number 2 starts shooting wild....
few others started......
I see micro air bubbles around the problem number 2 rocker nut...air in the oil?? maybe traces of similar in another.... but 2 was quite noticeable.....
Come to think of it, number 6 had been shooting bigger air bubbles the other night...I tried taking a video...Like they were spaced apart bigger air bubbles.....
So I test number 4 by tightening a quarter turn...no change...put it back and turn around and do a hot adjustment to get zero lash on all of them....
Shut it down and do a full turn on all of them....
Start it up, 2 taps then normal....Little noisier in general than I know it can be but no tapping.....
I counted my loosening while taking them to zero lash when running and I was at 1 full turn....just like it should have been from last night..why then the initial craziness? sitting open for a couple of days?...not sure they were going to quiet on their own.....
Doesn't make any sense...
And now lifters are randomly deciding to spray ...
I'm going to close everything up...dump a bottle of rislone in now that I relieved some oil level into my bay from the rogue shooters...
Frustrating...
I know new lifters on an old questionable cam isn't good but, these jokers are driving me crazy....can't be healthy for motor..?new lifters would just get screwed up again if I don't prove this dirtiness can go away...
Will see how this full turn handles the start up tapping.. would be nice to at least keep it to a couple of seconds at startup if nothing else.....
Kinda wish I had never messed with them but, the truck has run and sounded better since so the new tapping at startup will have to be tolerated for now.
chirping still there but seems to have moved from 2 to 4...still around 6....
Hard to tell but I'm not convinced the rocker rods aren't rubbing.... They all had shiny areas where they go through head when I cleaned them last month.....idk....hard to see but clearances are incredibly close afaik....i need to get a stethoscope...hose isn't focused enough...
