I have listened to all video's for both motors. Paul motor has a issue. TO me Scotts motor is good. Of course video's can throw things off.
Paul I'm thinking a timing chain issue or something in the both end.

Now that I have listened to the video of the stroker, and heard the video of pauls car, and heard it in person, I can say that the "clacking" noise heard in the stroker vid sounds exactly like pauls car. Does anybody know what this could be? The clutch "chattering" possibly?
my car is currently getting the exhaust put on as we speak..well see what it sounds like then..i will tell you this..it doesnt sound like it wants to die any more..but thats probably because i unpluged the 02 sensor

That is not clutch chatter. Also the clutch should not chatter at idle when not in gear.

HEY..my clutch doesnt chatter !!!
Keep us posted more vids NOW!

Any ideas as to what it is then?
it was just lifters..quads have a pretty loud valve train...more vids to come when i get the car back from exhaust shop..note though that i had to change the setup..since im about to add a full body kit i wont be able to put the muffler on at this time..so it should still sound rather mean
The lifters were making the distinctive CLACK noise? In the video you can really hear it when you let off the gas for a second at the car struggles back to idle. It sounds exactly like pauls car at that point. I think the noise in pauls car is already going away though, maybe it just had to be driven a little?
Sounds like it wants to blow up again.

ugh, i just dont get it. whats so hard about priming the engine and turning it over while on an engine stand, or bench? a freaking trash barrel even works!!! lmao
bolt starter on
run a starter button through the system
give starter button 12V power source and ground
DONE. push the starter button and wait for the oil to come out of the end of the intake cam (where the PS pump goes)... then u KNOW its got oil pressure, and you get to hear any noises and or find out if its put together correctly. you can also do leak down and compression checks to see if everything is kosher.
my experience:
engine we put in my white car, built it, did the starter button and turned it over, had oil pressure but when we did the leak down pressure was bleeding off through an intake valve. took it back apart and one intake valve had a TINY piece of shiit under the seat and it couldnt get it cleaned off, if it was an exhaust valve it would probly have been just fine, but it was intake valve.
cleaned it up, put it back together and after that every hole held its pressure perfectly. to this day the engine runs awesome, nice n tight.
these engines are just to complex with the timing and the DOHC's etc to just throw them in the car and expect them to be perfect, especially these engines with basically experimental parts. to me, id rather measure twice and cut once, get everything done the first time and checked and RE-checked. You guys have put FAR too much money into these beasts to NOT be cautious.
We didn't just toss it into the engine bay and hope for it to run. We went through the same exact process you did checking oil pressure. The bottom end of this car was professionally done, and everything is within spec. It was all balanced, and all clearances checked. Every breakin procedure was followed, everything was prelubed as it was supposed to have been, everything torqued to spec, it has all new gaskets, headbolts, and anything else that should be replaced etc. It is impossible to compare either of these setups with a fairly stock engine being put into a car. When you start removing balance shafts, using forged pistons, stroking the motor, tossing in wilder cams, stiffer springs, lightened flywheels, high staged clutches, poly motor mounts etc there has to be some weird noises happening. I am not saying that either cars engines sound perfectly fine, but I think that stuff just needs a little time to wear in. Both engines have less than 100 miles on them, and I don't think we can make a real diagnosis of what the sounds are or whatever until the motors have had time to wear in.

HA .. mine has about 5 miles on it hahahaha

my bad, i didnt realize you guys turned it over on the bench or something before installing it. sorry.
we didnt actually use a starter to turn it over we just clayed the pistons put the head on timed it took it apart and every thing cleared by 80thous nothing hit.
car runs great with good oil pressure not problems running or starting nothing no abnormal wear just normal metallic oil no big shavings.
i dont really see what the problem could be any ideas??
We did turn the car over to check for oil pressure paul, we just did it while the engine was in the car. We disconnected the oil pressure sending unit and turned it over without the plugs in it and waited for the oil to come out the top of engine, same method, different place for the engine

If anyone still hasn't gotten the video's to work, just go to photobucket and search; Paul Tjepkes. The tapping sound is less in the second vid. Probably just a break in noise. Glad to see it running. Now get the small things done, tune it, and burn some rubber.

And I hope you are right! The noise gets quiter every day. That has to mean something right? Its not getting worse at least.
good news..the stroker is back home! full 2.5" piping and no muffler at the moment till i get my new bumper on...still sounds pretty mean, at least its not in my ear though..car runs alot better with the exhaust on it if you ask me
and hows that noise, new vid coming?

I guess it just depends on how you look at things. I have rebuilt a 2.4 before. We did not test start it on a bench. It was a stock rebuild. We did turn the crank over by hand making sure everything was good. When we were ready to start the car for the first time I kill spark and fuel and turned the motor over to get oil pressure in the motor. I guess since I have worked on many 2.4's I do not consider the design hard to work on. TO take the head off is only a hour or so job to me. Not saying it is a job I want to do all the time, but still not that big of a deal to do in the car.
