I have everything changed and the car will run it just makes a loud squeeling noise and i'm pretty sure it can't be the belt. It never did that before. I'm wondering if its the cam? I lubed it all with assembly lube etc why would it be doing that? Its like "eeeeeeeeeeeeeeeee" ALl i did was changed to Vortec heads/ Comp cams cam/lifters/ New comp cams valve springs/ retainers/locks. It just squeels and makes me very nervous as an engine should not be doing this.... any ideas?

 

What cam did you use? Did it turn over freely by hand when you lashed the valves before starting?

 

Yes it turned over perfectly ok, Could it possibly be my power steering? I forgot to fill it (it should have nothing in it) would that make a noise like that? and i used A comp cams Cam. Heres the link to it..... http://store.summitracing.com/partde...4&autoview=sku

 

What do yo u think? I never thought a power sttering pump could be so loud but i guess i'll find out this morn.

 

Take the belt off and start it and see if it makes any noise.

 

I pulled off the belt and the noise is still there, Its really loud. Has to be the cam cause it makes that noise all the time.... I'll take a video and post it. It sounds like a freakin die grinder.

(video is with belt off)


And ideas? I'm stuck idk what to do.

 

I just called comp cams and they said its probably a bearing..... Any ideas?

 

Start undoing your work and see what went wrong.

 

damn and it took me forever to put it all in lol o well better safe than sorry

 

Do you do your own engine work Apeiron? Have you ever done a cam before? If you have what do you think i might have done wrong... Thanks

 

Did you change the timing set with the cam?

 

I was thinking the same thing, did you by any chance install a double roller timing set with a roller cam and forget to clearance it?

 

its a Flat tappet cam with a double roller timing set and all i did was put it on.... think thats it? i'll have the timing cover off in a little bit to see, i'll look for metal shavings lol

 

That's probably it. The double roller chain is wider than the stock link chain, and now it's rubbing on the bosses around the oil galley plugs. You can clearance the block with a die grinder if you're careful and make sure you catch all the chips.

 

they normally make contact at the very top 12 o'clock position of the boss around the top oil galley plug there, which is where you normally need to clearance it. Hopefully that's all it is and you'll get away cheap

 

Yup, just have to go to town on it with the die grinder.

 

I just replaced the double roller with an OEM timing chain setup and it still whines like hell...... any ideas?

 

I'd finish disassembling it and see what you have..

 

Well i'm wondering what you guys think i should look for? First thing i'm gonna look at is the cam, pull it out and make sure theres no bad grinding from something on it....

 

Not sure to tell you the truth, if it were me I'd start taking it apart and inspect everything as I go, lifters, pushrods, rockers, cam lobes and bearing surfaces etc.

 

you didnt put a pete jackson gear drive in there did you? haha

 

a what? pete jackson gear drive? what is that? lol

 

Ok so i tore the engine down again.... took the cam out and everything else and nothing looks worn weird/badly or out of the ordinary, i put it all back together taking even more precaution this time. Still makes the squeeling noise! I'm getting very fed up with this... I need help

 

Distributor gear not lining up to the cam? Oilpump? Sounds like something rotating fast and stopping when you let of the gas alittle.. Cam maybe pushing to much against the rear of the motor?

 

I just don't understand how it could do this when all i did was change the cam and intake and timing chain set. I didn't think i did anything wrong, it all went in fine. but according to the noise apparently not.

 

What parts can make this awfull sound?

 

thats basically what I'm asking.

 

idk if maybe you could have knocked a cam bearing out? thats the only thing i can think of. i did a cam swap and everything turned out fine for me.

 

I took the cam out again after i put it in and everything is in there..... theres no weird wear on the cam either... It has me stumped... kinda figures with my luck i am the only one with this problem ever!

 

so did you take any pictures?

 

not of anything no cause i thought everything looked fine....

 

Someone list off anything i could have screwed up changing the heads/cam/and timing set that could possibly make that noise. I'll make a checklist and go through it next time i take the motor apart to figure it out. Thanks a lot so far guys!

Also why are there two holes in the back of the camshaft? whats that for? And it seems like when its running it whines like hell but it goes away for a sec when i get on the throttle.... any ideas?

 

I need a list to do anything ppl, i'm kind of stuck, i looked at what i thought was obvious so idk

 

The wining sounds a bit like a starter , maybe check the starter before tearing the motor apart again..?

 

Its a brand new starter... i will check it though i guess you never know

 

Well i have the engine apart right now, i'm not seeing anything worn out, but i'm getting TINY bits of shavings of metal in the oil.. Its annoying b/c i can't find anything wrong.... everything looks fine to me....

 

Here are some pics of the Motor/Cam............

 

guess i'm on my own then......

 

well i dont know if this would cause your noise or not, but seeing as you have a roller block and you are using a flat tappet cam, did you install the cam and use a thrust bearing? Im not sure if it goes before or after the retaining plate, but for flat tappet cams there is supposed to be a thrust bearing used.

 

No there isn't.

 

If the thing is making that much noise, it's got to be noticeable at some point when you turn it over by hand. Keep checking everything at every step when you put it back together.

 

or a retaining plate..

I'm kind of grasping at straws here, any pictures of the backside of the timing cover and the timing set you're using?

 

You don't use a retaining plate either.

 

the area where the retaining plate would go on a roller cam setup around the front cam bearing looks like it's kind of shiney, but I can't really tell from the picture, there isn't anything rubbing there when it's all assembled is there? Just throwing it out there..

 

Just the back of the cam sprocket, like normal.

 

I can't really tell but at the top it looks like there's a little metal flake kind of hanging off (straight down from the middle galley plug slighly offset to the right) and on my screen it kind of looks like it's gouged a little.. hard to tell from the quality of the pictures though.. probably just my imagination but I figured I'd throw it out there for him to take a closer look in person.. not really seeing anything else..

 

could that spot where the top of the cam sprocket is rubbing the block be it? i never greased it up or oiled it... idk it it has any oil on it at all.....

 

What spot?

 

where the back of the cam sproket rubs the block...

 

Where is it rubbing the block?
