I got a 89 3sfe, and i have noticed lately that when the car is idling, a weird vibration type noise comes from the engine area. I popped the hood and checked it out, and reved it a little by the throttle cable, and notice that when it revs up, its fine, but when the revs go down, thers a quick clicking, or vibrationg noise that comes from the valve cover area. What do you guys think this could this be? Please help me out here. thanks

How about low oil pressure at idle? Maybe its time to change the oil pump.

500Kcamry, your response caught my eye becasue you say the oil pump. I have an oil leak and maybe the oil pump could be causing this too? How do i check to see if the oil pump is the casue of the leaking? Also you guys mention hydraulic lifters, how do i check that?

If it's leaking oil by the timing belt cover by the oil pan then it could be the crank seal (most likely), or the cam seal (maybe) or the oil pump bearing/seal.
My 5SFE developed a clicking sound at low idle, and it turned out to be the oil pump drive and drive gear set (about $50). These can be changed easily when you change the timing belt ($30).
Does your oil pressure light flicker at idle or lower RMP, try and see by lowering the idle RMP with it in gear and let the clutch slow the idle. Now I'm guessing at the lower end, but I think the oil light should stay off 400-500 rpm and greater.
Hydralic lifter info, I don't know enough about it. Maybe Toysrme could comment?

Normally the ticking is the hydraulic bucket lifters. They sit on top of the valve/valve spring/valve retainer and that's what the camshaft lobe comes into contact with.
There is very little oil actually flowing, and stored in the engine heads under any condition (much less than you would think). One of two things tend to happen:
1) They don't get enough oil, causing them to slap up against the wall they fit around
2) They wear out. Obviously; as they wear they get slightly smaller they don't perfectly fit in the hole, and they slap against the wall of it
(or if you're like me, you say fuck it when you're reinstalling them and just throw them anywhere)
I lost the pictures of the valvetrain I had a long time ago from when I took my heads off and ported & polished them, or I'd show you exactly, but they all work the same way.

How do i check the hydraulic lifters? Is it esay to replace the hydraulic lifter buckets?
Toysrme's post is informative, I never considered this. I think he he saying he changes the buckets because he's found the clicking comes from buckets developing play in their cylinder head bores. I think to do this the cams have to removed.
Normally when working on the valves, the buckets wouldn't be changed and the bucket top (shim disc that contacts the cam lobe) would be changed to a different thickness to establish the valve clearances.

so how much do the buckets usually run? How much should i expect to pay to get them replaced?
Toyrme, didnt u have a post recently about buckets from the yaris or something? Could u tell me some more about this?

I didn't, it was someone old school with that idea, but I semi-remember the thread. If it's the lifters, F them. They have to rattle around for years before they wear themselves out. Many cars do it over their entire lifespan.
If it annoys you enough to warrent a change, the timing belt must come off, so you might as well do the entire timing belt / water pump changing thing. Get ready to cough up some cash. It all adds up.

The only thing is, this is a pretty loud rattling sound. I can hear it from inside the car when its stopped and idling. It's really annoying. It's more of a rattling then a clicking tho, is this still the same thing?
Do you guys think if i used seafoam on my engine, it would diminish this rattling noise. Would the seafoam make my engine quiter? Would it run a lot smoother?
my cousin had the same problem with his Gen 2 (3sfe). it ended up being the spring located with the cams. it came loose and was spinning around making a tapping noise then it hit against the cover. my dad knew right where it was a what it was when he heard it. he has been working on toyota's for 27 years now. so thats just another one of the options that could cause the noise. hope it helps
