i think you're losing sight of the discussion at hand, maybe take a look at the OPs post instead of getting your ego involved. it's the internet, it's not that serious. if you hadn't noticed, OPs ILP rebuild would pass both your compression and leakdown tests while still leaving him with a ticking/knocking engine. the point with the 0 mile engine is that it's known good, you don't have to inspect or check anything aside from the authenticity of it being a 0 mile OEM Honda short block... someone at Honda already did it. i don't know how to convey that to you and i can't understand that idea for you.

in case it wasn't explicitly clear to you, the goal of this discussion all of us are having is to help OP put together a plan to get him back to a good running s2000 with the smallest chance of another dud engine...

 

Seems like OP did leakdown/compression on old engine not the new ones... Also on the rod knock video it seemed like that engine needed some wallwetting fuel, did not have enough fuel and almost stalled on quick throttle that's all I noticed on the video. One would think the guys that build the engine would like to receive it and take a look at what might gone wrong?

 

he did a leakdown a month ago when he found scoring in his cylinders that leaked a disappointing amount but not catastrophic. it read 10-20% according to his claim which is on the high end but not catastrophic if it was read cold.

On the second part, this is OP's engine #3 from inlinePRO, the guys who built the engine have already billed him 2 other times (the current motor being the 3rd) for the engine work and all the work involved with the in-and-outs... OP is trying to not do that again... they've had 3 chances and 3 years to do right by OP, they blew it. im not sure who's doing the machine work at inlinePRO presently, but jeremy allen used to be the guy at ILP that could make it right. hell, i'm willing to bet he's not around anymore or doesn't know OP is the same guy or he'd offer a free forged block to make it right.

 

This is exactly the situation. Unfortunately those 10-20% leakdown readings were as hot as they could be (car driven around to full coolant/oil temp for a while. Parked and then took the readings as quick as I could get the plugs out).

I'm going to mess with the car a little more this weekend. I'll at least get the VC off and see if I can find anything. If I have time I'll drain the oil/cut the oil filter open too.

 

Keep in mind this is a low compression 10.6:1 motor now running on an OEM ECU, also there is no airbox/intake attached to the TB so it's getting much more air than it's tuned for.

 

Gotta love watching people argue. Lol.

How y'all got off on leakdown #s from a possible bearing issue is beyond me.

A leakdown of 10-20% on a new motor tells you nothing other than the motor isn't broken in and the rings are not fully seated seated.

Quit complaining and drain the oil.

Inline told me that everything would be seated and broken in within the first 500 miles on all of these motors. I drove them all on a break-in tune from Evans for 1,000-1,500 miles before getting dyno tuned. This most recent motor has several thousand miles on it.. when does a bad leakdown become an actual bad leakdown? Others have commented on other threads/research that I've done saying they have single digit leakdowns on freshly built, unbroken in engines.

 

I was just talking to a buddy yesterday who knows a guy who just had an F24 built/installed/tuned by IP and the car is currently being trailered back to CT. SoS supercharged making 15 psi on E60, car only put down 406 whp. The F24 has 10:1 pistons. I'd be pretty pissed if that's all the power it made.....let alone the longevity of this motor will also be seriously suspect seeing the issues OP is having. For perspective, my stock F20 made 427whp on roughly the same amount of boost on pump gas. Understandably the stock F20 is 11:1 CR, but still.....that extra displacement plus running on ethanol still couldn't net more power? Either that motor has serious compression problems right out of the gate or their tuning sucks.....

Not trying to knock IP, and I'm only going off of the details I've seen and heard from others....but if I sent a car to have a motor built and spent 10 grand on the process only for it to come back making 406whp on E60....I'd be a little upset.

 

​​​​​​On break-in you did use a non synthetic oil, correct?

The engine doesn't need to be hot when doing a leakdown, but you MUST use 100psi of pressure when performing it. If that was the case, verify you can hear air escaping through the oil fill cap and not out the intake or exhaust valves.

 

Correct on the oil, correct on the PSI and yes, all air on all motors was aggressively coming out of the dipstick hole and nowhere else.

Will be draining the oil/filter this weekend.
