Hi guys,
It's funny, I just get to thinking about you guys, get back on here, and then my truck decides it's time to give me a query for you.
Over the last couple of days, my engine has developed a tick. It's inconsistent, sounds like a lifter to me, because it sounds like it's right on the top of the engine, but I'm not entirely sure. It's like... tick-tick-tick-quiet-tick-tick-quiet-tick-tick-tick-tick. It is most noticeable when the engine is hot. It also seems to go away when the RPMs go up.
Maybe a failing oil pump? Or maybe I do have a spring or something on the top of the engine going bad on me?
Some history:
This is a replacement motor with 50k on it. Has been quiet. However, we installed this motor over the winter of 07-08, and the truck got it's oil changed around march of 08. It's only had about 1000 miles on it since then, it sat around a lot of this time. Got a crack in my radiator a couple of months ago after I started driving it again, and replaced the radiator a couple of weeks ago.
Heard the ticking a couple of days ago, and thinking that it may be because my old oil (from march of 2008) was breaking down, I took it to good ol' Jiffy Lube and had them change it and put in 10/30. Still ticks. Went and got a fresh tank of 91 octane. Still ticks.
That's where I'm at.
I'd probably be spending more time digging into the problem and figuring it out myself but I don't think I'll have any time until this weekend, and I thought I'd see if I can get some of your opinions until then. :)

It's just doing it so I would see your post.
Hi Heather!!!
;D

Hi Bob!
>:D
Yes, she still has your knob.
-
And I still have her bikini.
-
Yes, she still has your knob.
Does that mean this is Nate? ???
-
No, I can call my truck a "she"... can't I? ???
EDIT: Wait, I can see where this is going... :o
-
EDIT: Wait, I can see where this is going... :o
What? With lil' ole innocent me??? :angel:
-
Going? I think it's already there...
Sounds like your lifters need to be adjusted. I know when I installed the JDM engine in mine the lifters were all out of wack.
-
Ya, it's there :o
Hi Bob, I still have your 5mm hex wrench ;) PM me with your address
And Heather, sounds like a typical lifter tick, give her an adjustment ;D
I was there when the Knob and Bikini swap took place :o LOL it's not as
dirty as you think :laugh:

Thanks, I was thinking the same... I was unsure though, because I thought I'd hear the noise from lifters continue as the RPMs went up, or the noise would go away when the engine warmed up. Seems to make more noise when it's warm then when it's cold.
But if it IS lifters, and it's doing this inconsistent ticking noise, well, maybe I just caught it early. Hopefully.
We were thinking about draining the oil and putting in 3.5 quarts of 10/30 and 1 quart of Marvel, to see if the noise went away... wasn't sure if that'd help or not.
In the end, though I'd probably just be delaying the real issue, if the lifters need adjusting anyway.

Hah! Was that clear back in 2005????
It HAD to be, because I went to CruiseMoab in 2006 and 2007.
-
The Marvel oil will clean the inside, but the noise will be the same, they aren't
hydraulic lifters so the cleaning won't help the noise, it could be piston slap, it
sort of sounds like a Diesel when it's running, but your noise is not consistent
but when you hear it is it a light tick or a knock like a diesel ?

I think what I'll do is try to get a vid of the sound and post a link here.
It's like... well, kinda like the noise the blinker relay makes. Only not as loud. :-\
It's definitely inconsistent. "tickticktickpausetickticktickticktickpausetickpausetickticktickticktickpause" :P
-
Could be an idle air control
-
Well, here's a video standing back and taking in all of my wonderful engine noises... plus the louder *tick* (which apparently is getting less intermittent, but you can still hear it).

I've got a video with the camera a bit closer uploading now.
-
Ok, a closer one. Wow, lots of noises in that engine. I must be deaf. Camera picks up more than my own ears. :)

That sounds like a really loose rocker arm.
-
I agree with Skyihranger, sounds like an adjuster nut might
of come loose, letting the adjuster turn anyway the wind blows
-
All right then... I did think it was in the top end. Sounds like I get a gasket set and some feeler gauges and go to town.
-
You don't need a gasket set, unless you have a leak. The valve cover gasket is rubber and reuseable.
-
Yeah, I know. It's like 10 bucks for a gasket set though. Might as well do it. There IS a leak in the back of that motor somewhere, I think it's either the valve cover or the oil pan. Haven't given it much of a look, but I'll at least take care of one of the options anyway.
:)
-
Rear of the engine leaks are almost always the distributor drive, an O ring
and some gray silicone are all that's needed for that repair
-
Oh, that's right. Forgot about that one. Thanks.
-
Yeah Wild, an O ring, some silicone sealer, a few hours, a mirror to see if you got all the gunk off, and some scraped knuckles! Then you get to have all the fun of re-timing your ignition. But Wild is such a nice fellow, I bet He'd come over and help ;D
-
Hah! Yeah, he's cool, though. I watched the guy rebuild a motor over two days in Moab. Nuts, but he was able to make the trip home!
-
That boy got skills!
-
Well, I set her lash this weekend, and it still ticks. There was a lot of varnish in the top of the motor, and I'm wondering if I've got something sticking. So... going to try the Marvel route for a little bit. I couldn't tell if anything was wrong with the rockers, etc. All of the adjuster nuts were tight. Maybe I've got a bad spring? I couldn't tell without taking anything apart I don't think. :-\
-
If it were a broken spring it could cause that kind of tick, but I think you
would of seen that, the only other tick I heard like that in another engine,
although it sounded more like a rod, was a valve seat that worked loose
and was slamming home every valve cycle.
Could it be piston slap? That will knock with every power stroke, and
could possibly be checked by pulling 1nplug wire at a time, just make sure
to ground it so you don't mess up an ignition module

Yeah I'll try that check for piston slap. I didn't see any broken springs... I might tear into the top again this week or next (won't have time this weekend) and take a closer look at the seats. That would mean a valve job though, right? Bleck.
Wish you lived closer! ;)
-
Man, I thought my motor was noisy. The first time I took off my valve cover I couldn't believe the amount of varnish and other crap coating the inside. Since then I've only run synth oil, mostly because of the turbo, and always toss a quart of Lucas in with each oil change. Cleaned up the inside real well and quieted down the top end as too. Have you ever changed the timing belt?
-
We put on a new timing belt when we swapped in this motor. For this week I drained a quart and put in a quart of Marvel, and I'm going to tear back into it next week after driving it around for a bit... I think I set my lashes a bit too high (.006-7) for an engine that cooled down too much when I was working on it. I'm going to tighten them up a bit. It got a bit more clattery overall. I still haven't had a chance to check for piston slap, I'll do that soon.
Thanks for all the support.
-
Ok, tore back into it today... and am trying to track down the noise. No, I didn't check for piston slap yet, (got a bit too eager) but I did have a question. This is fairly new territory for me, but I was curious. When you're at TDC, and your 1,2,5,7 are "open" so that you can fit your feeler gauge in between the rocker and the lobe... should the exhaust rockers that are open have any "play" in them, or should they be seated firmly against the valve stem?
Like in the following:
(http://img254.imageshack.us/img254/2293/valvet.jpg)
...Where the arrow is pointing, do any of you know if there should there be any play there?
-
If the valve is open, there should be no gap between the rocker arm and the valve, or between the rocker arm and the cam lobe.
One thing to keep in mind....depending on whether it is #1 or #4 that is at TDC on the compression stroke, determines which valve sets are open and which are closed.
-
Right, I'm tired, and I came back in here to delete that last post because I realized it's dumb, and I just made no sense. Of course they're going to be loose, because there's space there, at least enough so that you can fit your feeler gauge between the cam and lobe. Duh. :-[
Thanks though.
Now off to bed.
