Lifter questions

So i basically have two questions first what do you think a ticking in the motor would be it ticks when its cold and right before the oil gets to it like right when i start it in the morning and then it goes away until i drive it for a about 30 minutes then it starts to tick again i was thinking it was a lifter that was failing so i was going to change the lifter and if i could figure out which one it is can i just change one or do i have to change them all and do i have to do the 2000 rpm breaking again.

try putting cd2 (oil aditive) in it , usally cures it .

It may have the wrong oil filter, check to see if it has a relief valve in it.

Do you have roller rockers?

mite just tighten it a bit also

might be better to just adjust them as changing them could make things worse:eek:

Yes i do have roller rockers and i run rotella 15w40 oil. Also what is the best way to adjust the valves?

There are formulas on the net. I've never had to do my roller rockers. But I have found sites that explained how to adjust my other rockers. Pull off your valve covers and check to see if you have a loose one. If they seem tight, then click your motor over a few times to recheck and recheck. Just trying to help.

Google it.

youll need a diagram is it hydraLIC LIFTERS

Or you can warm up the engine---then remove a valve cover--start the engine--one rocker at a time loosen the lock until it clatters, tighten til clatter just goes away, go to next rocker in turn, switch to other side and do the same

Caution--can be messy, oil will smoke from the exhaust manifolds,however you will set the running valve train for your oil and pressure---

Also if you have any flat cam lobes you will notice that the rockers don't move as much as others
If the pushrods aren't rotating you have a flat cam/lifter issue

Jerry - been a while since I did a Chebbie - but loosen each to clatter, down til it stops then another half to three quarters turn is my recollection. And I do recall the oil bath.

But since I've already been wrong once this year.......:confused::o

I didn't go into the so much of a turn deal because everybody has there own ideas---for me, the issue was to make absolutely sure that the lifter was at the very extreme end of its travel so as not to have lifter pump-up which would keep the valves from closing----and maybe even valve/piston contact

this method usually was good for another 500-1000 rpms

OK - I understand what you were trying to accomplish now - and agree

At hot idle, sometimes they sounded like solids--been protested several times over that

You can get them little oil splash guards that go on the rockers and it wont be so messy .

they don't work on rollers

I have a couple sets of old valve covers with the centers cut out (like the picture) and it really helps to contain the mess when adjusting the valves. Takes a bit of measuring, but cut enough to feel the lash and adjust the nut..

Same here with an old set of stamped vakve covers.

someone used to make sbc valve covers that had the whole top plate surface come off leaving the fence around the rockers
