Strange noise coming from Redtop SR

[SR20d2fourT]

I have a friend who just got his SR running about 2 days ago and when he came over to show me how the swap came out his car started to make a funny noise. So we drove it around and about halfway through the RPM range in first, it started making a knocking noise. So we brang it back and investigated. The engine has oil, oil pressure and all fluids are up to spec. It sounds like a knocking noise coming from the far back of the valve cover. When you give it gas and the RPM's come back down it makes a loud grinding noise, kinda like youre grinding gears. You can only feel the vibration in the shifter and the clutch pedal. Any ideas? Any help would be greatly appreciated, thanks!

was there ever any metal in your oil? what about gas or anything to thin it out? get a engine stethoscope and listen to your block, also, take a video or sound file of it so people can better diagnose your problem with your car. My guess is rod knock or something, take off the valve cover also and examin everything, check to see if a rocker arm popped off.

you can go to the library and get a chiltons, they have a section for all of these internal noises with engines and it will tell you whats probably wrong with it.

Did he swap in new bearings before he swapped motors? Check the crank bearings for scoring if all else fails.

Well, turns out my assumption of what the noise sounded like turned out to be the culprit. His 5 day old SR swap is knocking and finally died last night. What a fucking gay company dude, really. Fuck that shit, selling dead engines. The ECU didnt even work, he had to use mine. This is a texas based company, I forgot the name. God damnit, they better send a new engine AND suck his balls while juggling cuz thats bullshit.

Sorry for the bad swap, is this importer from the Garland/Dallas area by any chance?

That sounds very familiar. It may be him. Im not 100% sure so dont take my word. I will inform tomorrow. If it is him, Im sure hes a good guy, just shouldnt be doing that shit. Check your shit first, then again, and then again, before you send it out. 2200 dollars is a lot of money especially for people like me and my friend who are in college and these are our daily drivers!
