its smoking

[ginganinja]

ok so yeah I have searched seems my issues differ from the what I have found so im looking for some zilvia input

just swapped in a ka24de to my s13 coupe and its been smoking since start up :facepalm: ill be as specific as possible

Smoke-white with a hint of oil smell but strong fuel smell, Smokes a little at idle, It shoots a huge cloud of smoke when I accelerate from a stop, I cant see smoke in my mirror if I drive normal low rpm shifting, I can see it at WOT from time to time

Compression is 180-180-180-180, no leak down test yet

engine runs strong and pulls great, idles perfect, coolant is not low and does not overheat, no mix of oil and coolant

I have cleaned maf, replaced fpr, replaced injector o rings, tested injectors, replaced o2 sensor, coolant temp sensor, new plugs, checked all grounds, thinking that it was a fuel issue causing it to smoke that rich but after all the replacement parts the smoke calmed down quite a bit and now im now pretty sure its only burning oil

n/a engine, emissions system deleted including pcv, bolt ons are h/I/e high flow cat

I was just hoping to get some input on some possible causes, Im thinking valve seals right now but anything else I should check for

did u do another compression check after you thought its burning oil?
and if your valve seals are not good your compression should not be 180 across the board. check small stuff first then work your way down the list; timing , dist, firing order.
take all your plugs out and compare there color and condition
(i know there new but check again)..your probly pinging the shit out of your engine too.

problem sounds like your getting water into your gas...........then pinged the shit out of your engine and rings or valve seals could be screwed. thats why you do another compression check.

How much smoke is coming out is an indication of the problem, and the smell is another clue. Sometimes the smoke will start white and turn bluish or black; oil of any automotive type burns bluish, and too much fuel makes black smoke. Not enough fuel burns gray, so a careful observation of the smoke can help determine the problem.

I did the compression test about an hour before I came to the conclusion that its burning oil, It was a perfect 180 on all 4 I even used 2 different testers just because I couldn't believe an engine with compression that good could blow so much smoke, timing is set at 20*btdc, tps is adjusted,

I cant see firing order being off due to the fact that the engine has zero power loss, does not hesitate or backfire It runs extremely well besides the smoke

The amount of smoke is noticeable at idle, heavy at high revs then starts to clear as it idles again, moderate under normal driving conditions, Heavy during acceleration from a dead stop like a stop light it does come out white with a blueish tint to it, slight and I mean very slight smell of oil, to me it smells like its running a little rich

I pulled the plugs and looked at the top of the pistons #1 cylinder does look wet on top the other 3 seem dry, the plugs look normal

I changed the oil as well today it was plain dirty oil no fuel or coolant mix

The confusing part is I bought the motor from a friend of mine who says it did not smoke in his car , It came out of a 95 auto with only 108k

If you overfill on oil this will happen.

Pull the intake manifold and look in the intake runner after a few good WOT pulls. That'll tell you if the valve seals are leaking. Although more smoke at WOT usually means it's something related to the combustion chamber/piston. Possibly a damaged oil scraper ring or something like that.
