getting worried, please advise!

[kr.k]

I have driven about 2000 miles after full 7 bolt rebuild (new crank, bearings, eagle rods and wiseco stock bore pistons) and for some time now my car does a really loud metallic blurr sound in the morning when started cold. It is not long like for a second or so but it sounds scray as hell!
One of my friends who heard it told me that it is a "bearings sound" that it sounds like my bearings are worn out! Can it be? any other things it might be? lifters? piston slap? bad brand oil?(GULF) I do not get that sound if the car is warm and I dont have lifter tick what so ever. Obviosly the shop that did the rebuild is saying its ok, all of mitsubishi engines do this sound bla-bla-blaa. It is really hard to demonstrate the sound as I would need to leave the car for like 10 hours to get that sound out of it, but when it does it is loud!
thanks for your input!

First, drain your oil then fill up with mobile 1 synthetic (It does make a difference!!). Then have someone else start up your car and listen where the noise is comming from. does the car drive fine after its warm and have plenty of power? if not your valve timing could be off and your engine is throwing back the ignition timing after it hears that

is it a scratching sound?

So I take it your worried about possibly a multi-thousand dollar problem developing.

What's the issue about leaving it for 10 hours? Take it over, leave it overnight (take the keys with you) go back in the morning and start it up for them. If this is as bad as you say, then it will be hard for them to explain it away.

piston slap maybe?

Corman12345 - Yea, I think I will change the oil to Mobil as I am about to do a oil change anyways. Today I did ask a kid to start my car while I was listening and it seemed to come from the upper part of my engine. Empty lifters maybe?

nineD5_GS-T - no it is more like a blurrrrrrrr for a second or two...

jpolizo - yes I am worried but the problem is that there is no places to take my car really. I am in a really small country with no actual good tuning shops etc. the guys that did my rebuild are ok. but they are totally fed up of my car and they say anything to get me out of their garage so they can make a buck with changing someone's oil etc. I am asking for your help guys so when I do find a shop that has competent people then I have the right questions ready!


FourG63 97GST - piston slap, that's what I have thought but as I have never heard such a thing I would have no idea how it sounds...

thanks for your replies guys!

Your first mistake was building a 7 bolt and having somebody who dones't want to deal with you now do it. You should have just ordered a built 6 bolt block from the USA and polped your 7bolt head on it even, that would have been much easier.

I just didnt have the money to do it that way.

If I'm reading this right, your goal is not to get the original shop to diagnose or fix the problem; is that correct?

If that's it, then what I would do, were I you, is call every shop in the area, explain what's going on and if they have a plausible explanation, or want to look at it, then leave the car overnight and have them listen to it in the morning. You are trying to find someone there who knows what's going on or can figure out what's going on. Getting someone else, 5000 miles away, to diagnose the sound over email and then having a shop address that diagnosis is likely to be expensive.

This approach assumes that if you find $1,500 worth of repairs, you are letting the original shop off the hook. From your description I doubt they will go ahead and fix it after some other shop has diagnosed it or torn it apart. If you don't want to let them off the hook, I'd take it over there and make the mechanic listen to it while you start it cold. I had to do that with a Ford here, once, the shop failed to diagnose a faulty fuel pressure regulator and kept telling me it was my "plugs"; I had to walk the guy to the back of the car and litteraly point at the clouds of smoke pouring out -- they did fix it, however.
