 |
|
I have been driving my bus, newly refreshed with a Web cam and hydraulic lifters, it's a '79 and I wanted to stay with the hydro's, so let me know if there are good reasons to switch to solid..
I was going by the book and adjusting these 2 full turn in after zero lash.. the builder told me that they need only 1/2 turn in.
I've been driving it like this for 3000 miles.. should I be readjusting them to 1/2 turn in? Anyone else running this combo who can share their adjustments?
Thanks.

The cam has nothing to do with the preload; that's all inside the hydraulic lifters themselves. I'm a big fan of asking the engine what it likes, but if you have a warranty you may need to discuss it more with the builder. (Though it seems your engine likes two turns preload?)
The new hydraulic lifters on the market don't seem to have the same internal dimensions as old lifters. One way to find out would be to find your zero lash point, and screw the adjuster in until the actual valve itself starts opening. (It will be very hard to turn the screw; oil would be good on the threads here.) Count the number of turns in until this happens, and report back here next time you do a valve adjustment. Of course, reset afterwards to your chosen preload…
Fun reading here:

If the engine runs well and doesn't make any clattering sounds, I really doubt you are doing any harm.

Thanks for the reply.. it does make a bit of noise under load at low rpm... sort of in between an underwater exhaust and a diesel.. but to me it sounds good.
Just to throw this in there.. I am only getting ~12 mpg.. but I do drive it 70 - 75 mph (indicated) at 250 mile intervals (It may have been adjusted really rich a couple of summers ago bu a mechanic who was compensating for an air leak)

A hydraulic lifter clatter is a cantankerous racket that goes away with time, clean oil, and easy driving. It is not load or speed dependent.

Ah, the classic vacuum leak cop out. (Do a full 250 mile trip at 55-60mph and see what happens  )

Oh, no clatter, just sort of sounds like a water-cooled boxer engine.

I have a Web cam and their matching hydro lifters. 1 1/2 turns in. I did send the valve springs back to Adrian at Headflow Masters as he had set the heads up for solids (for someone else's project) and he sent back a set for hydro springs. I've checked the valve adjustment a few times a year and it has not changed, loosen 1.5 turns and the adjuster is right at no lash.
I do have a lifter that clatters for a few seconds if the bus sits for a few days, but it pumps right up.

Hmm.. Adrian is who told me 1/2 in.. I do feel that 2 turns might be a little much.. I'm going back to 1 1/2 when I do my 5000 mile oil change..
