Well after boosting a bone stock jdm b16 at 8 psi, I can say I have officially killed it. It’s no big surprise. I have been doing all the things that you should not do for 9 months, boosting 5th up mountains, tuned w/o a dyno just reading plugs and A/F and just basically driving it like I stole it. I noticed a lack of power lately and today on my way home from work I noticed smoke coming from under the hood. Smoke was just pouring out the valve cover breather. I killed the rings or blew the headgasket. It was a relatively conservative tune though I wonder if running the E15 had anything to do with it. In boost I was running about 11.80 at 19*. Oh well I have a new bored block sitting in the garage. The new set up will be.
Wiseco 81.50mm
Eagle rods
Arp head studs
Gsr cams
I still need spring and retainers. Should be fun. I’ll be running 12lbs low and 18lbs high on my gt2871 and I’ll tune it on a dyno this time.

Here is a lame video of smoke coming out the valve cover vent.

yea same as around here. 10%...although i didn't notice much change if any in cars running the new ethanol mix before and after. The ethanol should have made a change, but I guess it already had a high enough percentage in it in the first place that the 10% really isn't changing much.

 

it's 15% here. i pulled some timing after filling with it once cause i had some det. but seemed good after that. plugs looked fine.

 

My engine used to smoke a bit like that after hard runs. I had a breather filter on the valve cover and that much if not more smoke would come out.

I just kept on driving it though. I thought it was normal. lol. I still had good compression too.

I say keep on flogging that **** until it REALLY gives out.

 

should of saw my when i blew my engine at the dyno
10psi on a stock b16 t3/t4 57trim. sad part was it only made 240hp/130 or 140tq. weak sauce b16s!

white smoke blew out everywhere from the valve cover. oil was dripping out of the downpipe. took it out for a spin after we got it off the dyno. smoke cover both sides of the road. my end up being 4 cracked ringlands.

I thought you put a built motor into your hatch

Thats nothing though, there was that 530whp stock b16 that kept going a while w/cracked ringlands, and the tard that boosted my old b18 hatch blew it in a day. White & blue smoke (alternating lol) like a military smoke screen, barely could accellerate at WOT... No, you could do way worse. Its good you're saving it though - killing a motor needlessly is just stupid. Unless you're in cali, since people use b16 shortblocks & d16's as doorstops

 

sounds like u need a valve adj really bad

but that would prolly be a waste of $$ cus u got a bad seal somewhere

no i just changed the headgasket and slapped the turbo stuff on there. but the one i'm putting together now should be pretty strong. but for now i'm stuck driving my m3

It sounds funny but that old guy loves driving his EF.

 

Just a follow up. All that said ringlands, go ahead and pat yourself on the back.

Here’s a carnage pic. Both pistons #3 and #4 let go. Every thing else looks good though. I’ll throw it back together as a spare engine, just need a piston and a new set of rings. I’ll probably start building the new engine tomorrow, this time forged pistons.

 

surprised that was still running so well
