If you're autocrossing doing some maneuvers and at the revlimiter, the engine and wheel speeds will be fairly constant no? I assume if oil starvation you lose pressure and if you have a blockage (like bearing) you get increased pressure? I actually dont know if the flow is diverted with increased pressure. .Maybe i can google this when i find the time. just thought maybe theres a known telltale sign

This is very easy to say, not so easy when your car is apart. This will need to be parked on the street too (hmm could get stolen) when i take it home. I am hoping it can be put together and running to some degree so i can move it around.
what do you do if they told you an acceptable bearing clearance? I have no doubt they have bult drag evos and eclipses but obviously the usage/abuse is different
I hope you provide the same response when I post on FB later when I'm all sorted

 

Did you check the oil pickuop to pan clearence when building the engine?

 

Yes I did on the 1st motor. IIRC the IE pan requires evo9 oil pickup tube.

 

I'm with Austin: If a shop is trying to keep the specs of your own motor secret from you, that's weird.

 

It's not that. they can just tell me the correct number from the spec sheet or whatever and you cant prove if that was true or not. I dont think the engine build was bad at all (93 was way de-tuned tho). It's not a special build. stock crank 2.0l similar to the previous one. Bumping the rev limiter to 8500 from 8300 is obviously opposite of the reliable engine I paid for. I even asked why he did that even after the previous engine spun#4 at the rev limit. he just said to trust him, this is exactly what he would do if this was his car. you know how it goes

 

8500 rpm didn't hurt the motor. The 2.0L with stock rod length can do 10,500.

 

oof

 

My first question is what kind of oil are you running?

 

I also have 7 2.2L's out in the wild on their idk how many track days with the rev limit set to 8500 for stock frame turbos, or 8900 for turbo kit cars. Also have several drag/street cars that are set to 9400. And don't tell me drag racing isn't abusive when a car leaves off the 7500rpm 2-step and spends 9-15 seconds (1/4 and 1/2 mile) above 6500rpm making 900whp+

 

dont tempt an autocrosser with that. thats probably 20mph more anyone wants to try it? I'd try stuff I see on evoms but maybe not this one

 

Brad Penn 20w50 on both motors

 

So I went to visit the shop today. I asked about clearances and he said "2.5" ... I dont know what that means and I dont know if I asked the question correctly.
As it turned out all the bearings are scratched up, quite evenly except for #1. It just so happened that the #1 made the rod knock sound
I just checked the "backed up by data" it seems there's no data above 7800rpm (which is understandable). well that sucks, i may have fallen for eye candy again
The engine builder said he has not seen this type of design where the oil pressure regulator is relieving on the side of the pan, speculating maybe some aeration or just oil flow patterns made by the rubbery gates is actually going/pushing away from the oil pickup and out of that small compartment at certain rpm/oil pressure. Nobody knows. There's no data. No trash talking, all speculation.
We're going to try to rebuild. No warranty even if I use the OE oil pan/regulator. Fine, i bet this autocross business and no logging is a liability. I told him I'd keep using the IE oil pan, we'll see if it happens again even with a lower rev limit. While driving home, I'm wavering a little about that. The issue is repeatable and hard to ignore.. There's got to be some science there. Statistics?
Stupid me is thinking I should have a 2.4l project on the side, I just thought that has more headroom for reliability & improvement. I dont know anything. Downtime sucks.

 

It seems more than 1 cap is burnt. i just noticed it now and didnt inspect all of them

 

Jesus that thing got wrecked. Every bearing is hurt.

Need pictures of the oil pump...

 

Those bearings are beat. Might be contaminated oil or bearing tolerances are way off.
