Here is the chain of events. (wont mention the name of the shop at this time)

This is a 92 h23 built turbo prelude, and i am the second owner. I bought it from a good friend of mine (Silverludesi) and i know the car pretty well.

The engine was built last summer with:
-je 9:1 pistons
-GE sleeves
-Pauter rods
-new crank
-line bored
-p&p head with custom dual valve springs from Portflow
-hondata 3b
-aem fuel rail
-720cc injectors
-arp headstud
-the shop's own brand of cam gears
-etc, etc.......other things which i dont think pertain to the problem.

After the engine was built it has always been very noisy. We thought it was from the head because of the dual valve springs which we thought was why it was abnormally loud. After the engine was built, it was retuned and made about 240 at 7 psi.

After a short period of time, the cam gears broke...as in the cam broke off the gear which led to a couple bent valves. But the shop is very reputable and responsible and they took care of it.

After they fixed it with new valves and a redesigned version of thier cam gear. the car didnt seem to run right still. It was still very loud and the EGT was very low and the car was weak.

I went to a different shop to mainly get it on a dyno and see how it was running and to also get a new downpipe since mine was all bent. This shop also has very good expirience with the H series engines.

Now what they told me is that the sound coming from the engine is not very good. They said it wasnt coming form the head and was not the valve springs. They said they thought it was coming form the bottom end, sounded liek a bad bearing or piston slap.

They did a compression test and came back with:

160, 140, 140, 150
(keep in mind these are 9:1 stock bore JE's and GE sleeves)
They also put it up on thier dyno and it only made 211 whp at 7 psi.

So i called the shop who originally built the motor and they said theyd look at it again first of next month which is the soonest possible.

Well as my post comes to an end, kinda wondering why im postin this....i guess to just vent and let this up for others to ponder.
I guess my question is, what could cause the noise from the bottom end, what could cause these compression numbers on a freashly built motor, any ideas or any kind of input anyone has, and i guess im lookin for a little assurance anyone could give me at the least.

Just a thought, but how many miles on new motor?
Rings may not be seated all the way?
Also, what kind of rings did you use with the new sleeves?

I couldnt say as far as noise, would need to hear it myself.
