It took a few cranks but it started right up first try like they do on tv. I'm proud of myself. There's a few leaks here and there that I gotta address but it idles pretty good and it's on the stock tune right now because i couldn't get the computer to communicate with my laptop, still working on that

Aside from the leaks there is one more problem. When giving it a small rev and letting it drop back down i hear a noise, it's also there if i hold the RPM slightly above idle. It's hard to explain the sound but it dosn't sound like a vaccum leak. I thought it might be coming from the alternator so i took the belt off and started it up. The noise was still there. It seems to be coming from the front of the engine, possibly the throttle body area. I thought maybe it was the IAC so i disconnected that, the noise wasn't there but it was idleing at 1500 rpms. Maybe i opened up the throttle blades a little too much for the 383?

Could this sound be coming from a leak at the IAC? Yesterday i attempted to take the iac out to clean the passage inside but the screw stripped after 2 about turns, so really it's just held on by one screw for now.

I didn't get a chance to go through all the TPS adjustments and checking iac counts, i'll save that for tomorrow, it's dark out.

One more question, is it normal to burn a little oil initialy at start up? Once it was idling for a few minutes, got about up to operating temp the exhaust didn't have much if any blue tint to it.

I have a video later i'll try and upload to show the sound.

Engine setup:
Golen 383 Street/Strip Shortblock - eagle cast crank, scat 4340 forged I-beam 6" rods, SRP forged pistons, melling HV oil pump, ARP main and rod studs, celvite bearings etc
Advanced Inductions Street/Strip heads/cam package
Comp Cams rocker studs, pushrods, guideplates, double roller timing chain and Pro Magnum 1.6:1 Rockers
Advanced Inductions Street/Strip ported intake
Yank 3000 stealth stall
Racetronix 37# injectors

 

Sounds like a nice setup, congrats on teh startup man!!

 

Congratulations! I remember when I fired up my engine for the first time. It started right up, no leaks, hopped in and drove it. It was one of the best feelings I've ever experienced!

It is normal to burn some oil befor the rings have seated. If the engine wasn't pre-run by Golen(I doubt it was), you'll want to get the leaks fixed before you idle it too much, and go out and drive it. Accelerate at about half throttle in third gear, then let off and coast to about 20 MPH and do it about ten times. This will help seat the rings and once that's done the amout of smoke should decrease quite a bit. I have no idea what that sound is you hear, but I'm sure you'll find it. I do slightly remember my engine being mechanically louder the first few times I started it up. Congrats!

 

Well does the sound, sound like air being sucked (vacuum)? Metallic sound? ticking,tapping? etc? Oh btw congrat's on the startup

 

Thanks for the congratulations guys. Here's the video of the noise, I'm holding it at the rpm it makes the noise at. Anything over it and anything under it and it's fine. http://www.3gc.net/misc/MVI_0887.AVI

 

Hmm sounds like it's a reciprocating problem i.e somthing that spin's lol.. timing chain, water pump.. that's my guess..

 

Maybe the timing chain. I have a double roller, I thought I clearanced the cover enough. It didn't rub when i spun the engine over by hand with grease on the chain and the cover on. Maybe the chain stretches and expands while it's at the certain RPM and is moving to a spot that i didnt' quite grind enough off of? I'll put something up to the cover and try and listen to it, see if it's coming from there tomorrow. I don't want to pull the cover for no reason though.

 

DO NOT RUN THE ENGINE ANYMORE!!!! TAKE IT APART AND CHECK!!!! I can't stress it enough you will ruin that new motor!!!!! STOP NOW ANDPULL IT APART!!!!! Better safe than sorry IMO... that's too much money to be throwing away.. especially if it's not they're problem....

 

Ok, I guess I'll pull the timing cover today when I get home from school. Will it be apparent if that's the problem? There should be a few metal shavings in there right. Is it likely any serious damage could have occured running it just for those few seconds when it was making the noise?

Anyone else ever have this problem before?

 

chekc your oil too.. they'll def. be in there.. my buddy had that issue when he swapped in his when he put that chain on there w/ that timing cover.. it took out his motor...

 

There wasn't any noticable metal in the oil, even put a magent in it and didn't get any noticable metal. I got the timing cover off and there were a few scratches. I didn't notice them at first but they were there, i went crazy and grinded a lot more off the cover. There wasn't any metal in the cover and no spot on the timing chain looked like it was rubbing so i'm hoping there wasn't a lot of metal floating around the engine which could have caused damage. Hopefully this solves the problem 100%.

I need to order a new opti seal from the dealer because my hand slipped with the dremel and cut it but everything should be back together tomorrow.

 

did you clearence your oil pan? might want to pull the pan and see if its rubbing there.

 

Well lil hard to pull pan w/ motor in the car... Try the timing cover which you have already.. better safe than sorry.. Sorry i overreacted i'd just hate to see your brand new motor ruined... That's a common issue w/ the conversion.. my buddies car sounded like pacman and it only took him 10 miles to wipe the entire motor out.. i'm guessing your clearance was a lil better than his was.. But why chance it? but i have seen the crank hit the oil pan's on a 383 before..

 

It sounded like possibly that TC was rubbing the cover... hope you got it figured out. I wouldnt worry too much about ruining the motor though.

Take it out and tell us if it scares you!

 

my boss took out his 383 because the pan wasnt clearence, it lasted about 2k miles.
