I think it's coming from the water pump, but too bummed to even look at it. Am I asking too much for my car to just operate normally? I barely drive the damn thing. Im almost sure the guy did the water pump when he did the timing chain. Hasn't been three years yet. :013:
-
I guess you are going to have to look and see if it is coming out of the weep hole, around the long bolt that goes into the water jacket, or around the gaskets between the pump and block, and/or the hose.
Driving the car seldom does not help
-
Phil...hang in there. This stupid Impala SS gave me fits...so I parked it awhile. I got it sorted out...and it's running like a top. Changing the water pump ain't that tough. Get stuck...and the guys will be here to talk you through it. :)
I agree with Steve. Let the car sit...and seals etc dry out.
-
You have to remove the water pump to do the timing chain.
Odds are it's weeping out of one of the long bolts. If that's the case the fix would be pretty easy as long as the bolt threads aren't rusted all to hell...
...or just drop in a GM seal tab.
-
I plan to do my own work from here on out. I hope to get chance to check it this weekend. I need to get under the car to see exactly where it's coming from, correct? And by not driving often, i mean every two weeks. Weekends depending on the weather.
-
If you start it and the under the water pump hole pisses water you found the leak. If it comes from elsewhere that is a discovery you will have to make. Just remember that the pulley and belt are moving when the engine is running. No loose clothing, or you could regret it.
-
If it's the weep hole on the water pump, there should be a visable stain where the coolant sediment stained the casting. When one of my old rusty long bolts leaked there was a green ring where the bolt head met the waterpump and a nice little green droplet hanging down.
-
I checked everything around the water pump, and it seems fine. I then discovered that the leak was above it. As soon as I began to loosen(not even one turn) coolant started coming out of that hose right where the clamp is. After making a mess of inspecting the hose and tightening it back, I decided to wash the coolant off of the spot were it had been. I'll have to wait until its completely dry before we know for sure.
-
Needless to say, after giving the car a jump and getting it started, I heard something worse than the leak of coolant. I'm almost positive that the sound I'm getting from the motor is internal. My stomach hurts worse now. I'll video the sound after I eat. The car seems to run fine, but this knock sound isn't good.
-
So the S-hose leaked... and now you have lifter rattle?
-
Earl's prolly right. Make sure it has oil pressure. Sitting too long...you may have to reprime it. Seen this situation more than once.

Sorry for the delay. Just back from a cruise. It was fun
-
check your flex plate bolts and your intercooler bolts.
Oh, and get some zipties or safety wire on those boost hoses running from the MBC :)
-
does the sound go away when you rev the engine a bit? If so, I would guess cracked flex plate...cracke d between the mounting bolt holes...
-
Phil...is that the original cam in that engine? I've heard that sound before...drove Dan and I nuts finding it. The cam button spring had broken. Steve...did the original cams have a plastic button on the nose of the cam? If so...it mite have gone south.
-
Believe it was

stock cam does have a plastic button on the end of the spring.
on the video there's one good throttle blip that sounds like everything got quiet.
-
All stock internals besides valve springs and timing chain. I believe the sound quiets down with a little rev. Now for the rookie request of the day...anyone care to elaborate on the flex plate?
-
Reluctor wheel hitting the crank sensor?
-
flex plate is the "fly wheel" that the torque converter bolts to
-
Ah. Ok. Thanks. I'll check that as soon as this poison ivy gets healed!! :013:
-
Phil, where are you living now a days? Didn't you live in Warner Robins, GA at sometime or another?
-
My cousin Charles was down there!! Im in Saint Louis. I'm going to contact a guy from the other board and tell him to come over tell me what he thinks. Been wanting to ride in his TR now for some time. Has every mod on it. Lol
-
That's right it was Charles. I hope you get it figured out!
-
whatever it is, its not major. started the car yesterday and drove it today. i'll get to it this Sat hopefully
-
Found one leak, fixed it, then found another leak at the top of the S hose going from the water pump to the heater line. I replaced the S hose, and then found the source of that "knocking" that I heard. The damn problem was right in front of me!! Right as I noticed that the damn car was still leaking, I noticed the pulley on the water pump was going nuts!! The water pump is shot though, and that's were that leak is coming from. :hmm :hmm :hmm :hmm :hmm :hmm
-
Check your pulley alignment before you bolt it up I had to press the pulley flange down on mine almost an 1/8 of an inch ate belts and squeaked at start up.
-
Thanks for the help!! Anything else I should check? Do I need a new pulley or am I ok? The pulley is loose for sure because I was able to move it by hand
-
Are the fasteners tight? I have seen pulleys cracked like the flex plate does between the bolt holes. Though I wouldn't think that it is common.
I got a water pump for about $15 and the guy behind me in line at the part house couldn't believe it was so cheap. Pick one up and some sealant for the long bolts, make sure it comes with a gasket.
I like this stuff.

Not exactly from bolt hole to bolt hole but it made a lot of noise.
-
Damn!! Thanks a lot Texas T. Does the new water pump come with a pulley?
-
You'll have to move your pulley over. And make sure the belt runs true. Odds are the pulley flange is in the wrong spot and needs to be adjusted.

Might be time for a pair of hoses and an "s" hose if you've never replaced em. Pulley gets transfered as per earl. You might even(read:probably) have to pull the studs out of the old pump to put in the new. Just double nut em and reverse em out then into the new one.
Man that is a clean engine there earl. Even new I don't think mine was that clean.
NICE!
OH, and some never seize on the bolts that go into the cover. Steel and aluminum don't play well together. Be careful getting it apart. You don't want to break any off.
-
It was only that clean since it was the first time I built the 4.2.....
now I'm on round three as the stupid dump Speed Pro slugs have proven they'll crack at the drop of a hat and I have to put my 'earlbrown' forged pistons in there! :)
It sure would be nice if I enjoyed pulling engines and putting them back!
-
I can have the engine out of my car and on a stand in an hour. :) School me on these Speed Pros...cuz I beat the crap outta these Sealed Power/Federal Moguls for 3 seasons...with zero issues. Or are these Speed Pros I beat the crap outta? :) H521ACP .030
-
That's the one's. Inside the oil ring groove, damn near the entire skirt is one big slot. For some reason I have the ability to rock the piston just enough to crank them at that spot and pinch my rings.
That reminds me, my new forged 4.1 slugs are growing dust. I need to float and balance a new set of rods and put that damn thing back together...
-
That noise really sounds like my car did when the balancer worked itself loose. Good luck and keep us posted

Earl...who in the blue hell makes these pistons? Is it Sealed Power...Federa l Mogul or Speed Pro?
-
Yes.
Federal Mogul, Speed Pro, and Sealed Power are the same thing.

Sorry for the late reply. Been traveling for work. The hoses were my first replacement because thats were I thought the leak was coming from. I can video the pulley and how bad its moving if you want.
