Car:90 crx dx converted to obd1
Engine:92 b18a
ECU:pr4

Ok...let me start off by saying that ive had this engine in the car for about 6 months. lately the car has been acting really weird. The ecu is throwing code 14 which is the iacv. Ive changed the iacv to a known good one and it didnt help a thing. I noticed that the insulator on one of the wires was cut right at the plug...so i took it all apart and and rewired it...which did absolutely zero good. I havent ran a wire straight to a9 yet but im gonna do that in a few minutes. If that doesnt work then im really gonna be stumped. Ive got a s2 IM so im not running an fitv. Also...could the iacv be causing my car to run rich?

The car is also burning oil, coolant, and running rich all at the same time(which is taking a toll on my plugs and 02 ). I cant figure out how im burning oil and coolant at the same time...ive changed my oil a bunch and i havent seen a drop of coolant in it. So my hg is probably still good. I dont think its the valve seals because if theyre bad the car will usually burn oil at idle and/or while decelerating(from my experience anyway). Ive got arp head studs but i didnt retorque them like some people say you should do...but if that was the problem i think id have coolant in the oil.

Parts ive replaced:Fuel filter, all vac lines, iacv, 02, IM-tb-iacv gaskets(but they were cheap...i need to get better ones), pcv, timing belt & tensioner, cap & rotor, plugs, wires, spark plug o-rings, cam seals and vc gasket. And thats just in the past month or so...every other gasket and coolant line, etc, was replaced when i put this engine in(and i mean EVERYTHING was replaced...i learned my lesson with my other 2 engines )

Im not a mechanical genius or anything...but ive been messing with hondas for a long time. Ive never had so many things go wrong at once like this. It makes it practically impossible to troubleshoot. One day my smoke will be more whitish, some days blueish, some days blackish. I keep saying "ish" because it burns everything so its never really one solid color

Sorry for the long post but i really need some help...this has been on ongoing thing for over a month and im fed up

 

Nobody? I know this is in the right forum because its about as technical as you can get. And technically...its a big pile of horse ****

 

Try doing a compression test and see if that will provide any insight. The IACV could possibly be the cause of your rich running engine. Do you have a fluctuating rpms at idle?

Yea ive tried doing a compression test....unfortunately there was soo much oil in the cylinders that i couldnt get a real reading. And yes my idle fluctuates but only after its warmed up.
