Ok so I blew my stock d15b7 in my eg so I picked up a jdm d15b from jdm engine depot put the.motor in fixed some little stuff and it smokes like crazy its Weired cause sometimes at startup its fine then I drive and ill see clouds of smoke then sometimes there's no smoke at all I checked the oil level its good I checked the coolant its good to Wat could be the issue everyone is saying headgasket but if the coolant is good how can it be a headgasket someone please help

 

What color is the smoke?

 

I guess I can't realy explain it its like a white smoke which I kno means antifreeze but the coolant level is un altered

 

You may want to check and make sure you haven't got any vacuum and coolant lines mixed up with one another. Also check for the presence of exhaust gas in the coolant and do a compression test.

 

No coolant lines are mixed up wit vacumes and exhaust gas in the coolant??????

 

Bump Tttttttttttttttttttttttq

 

bump, we`re waiting...

 

i got one a while back i think you just need to let it all burn out when they store the engine they run this greese **** through it so that when it sit in a warehouse or were ever, it's internally protected, when i started mine it smoked down the block but i let it idle for about 20 min after about 15 min it stopped smoking

 

I've had the motor in for a week changed the oil in it twice cause it was black as **** the oil is back to gold after flushing 7 quarts threw the motor buy still ***** smoke but no overheating no change in coolant and I noticed ill start it up it Will b fine and when I drive up a large incline it smokes very heavily idk Wat to do

 

here's a question do you have any cels first?

 

check your compression, then c if ur pcv is working mayb also..

 

Nope no cel's

 

I'm doin a compression test tomorrow and if it was PCv it would be black smoke I presume but ill check that to now any one know Wat headgasket to use for the jdm d15b and please don't guess lol

 

Ok so I leave work this morning and I'm driving no smoke I get to a hill tons of smoke back to flat ground no smoke hill again smoke so it only smokes when motor is on an incline do maybe that will help someone to figure out Wat the **** is wrong with this motor

 

No. The compression test will do that.

 

Yeah my boys shop opens at 10 I'm taking it there wen he opens

 

Are you sure it's not blue smoke (=burning oil)?

 

Compression test done 180 across the board

 

Any sohc vtec head gasket. just as long as the motor was never bored.

all d15/d16's have the same bored at 75 mm the difference in displacement is the stroke. b series are the same way they all have 81mm bore with just longer stroke. ( b20's are a exception with a 84mm bore).

 

thanks u sir

ok now after compression test we checked the map sensor and the o ring was missing after replacing then we changed the purge solinoid on the i/m cause it was broken changed those and reset the ecu the idle sits at 2000 rpm and the idle adjustment screw was turned down as well as the iacv cleaned as fat as the fast idle valve its bypassed so no cleaning of that needed cant fix the idle AND NO I HAVE NO VACUME LEAKS also wat valve seals for the jdm d15b and can i install them without removing the head

 

silly question.... Did you overfill the oil? Also did you have the oil pan off and see if the windage tray or whatever its called on a honda was in there?

 

oil is not over full and no my oil pan is not off

 

Bump for some help

 

the tilt of the engine probably doesnt have anything to do with it. If I had to guess it's when there is a load on the motor...You could be running very rich...

 

check your plugs and see if they are filthy...
