ok today i went to the dyno and after the 3rd pull the oil dip stick shot up about 4 inches and oil shot all over my motor. could that be from to much oil or the head gasket blown??? or something else?

 

Probably head gasket or #4 went byebye

 

dude thats not good, sometimes a popped piston can have those symptoms

 

yeah but it drives just normal... before it happened. im thinking its the rubber O rings and it was sealed tight

 

Could be that you need a new intake manifold gasket, but more than likely your almighty tuner just sent one of your pistons to a better place.

 

i dont think so, you would be able to tell if one pistons gone. i mean it still pulls fine before it happened

 

lol i had this same problem..check my engine build in my sig because of what happened...it will run fine for about a week..but u will have white smoke coming out of the oil cap..then it will start smoking like crazy from the exhaust..head gasket crapped on u and if u keep driving it say bye bye to ur ring land...to give u a visual

 

so i guess ill drive it for sometime and see what happen. i really think its the dip stick cuz its really easy to pull cuz the rubber rings were done

 

lol, i would plan for the worst right now. I wouldn't be driving it around hard and "see what happens" or else your car might really hit the bricks.

 

ok.. but if one piston is gone wouldnd that make it rune alittle weird?

 

Yeah but it still might be the head gasket like Raven said.

 

yeah thats what i thought but i checked my oil and i have no air bubbles or anything...

 

It wouldn't just be the orings on the dipstick because it takes a little more pressure than normal to build up in the crankcase to do that. I wouldn't drive it until you solve it....

 

its a daliy driver. well i guess ill see in a week or so if white smoke comes out. but i hope thats not the case or im screwed!

 

rut ro raggy

do a leak down, and a compression test.

 

ok what should the compression read across? 150 or 180? and if i pass that then what do you think it could be?

did you try to put a peice of paper to the exhaust to see if it gets sucked in? because someone told me to do that and its blowing air out like it use to

 

i have no idea what the numbers will be. just that they should be with a very small percentage of each other

 

yeah, every car is different on that.... like area said, they should all be really close to each other. It is super easy to do though.

 

I concur. If he's lucky, he just needs a new intake manifold gasket.

 

all i know is im happy my shitted on itself..gave me a reason to build..

 

OK this is his friend on his name i was with him. Ok im thinking thats it need an oil catch can or someway to vent the crank case because odviously hes running alot more boost than stock so I would have thought its just not vented enough because my rb20det 240sx blew the oil dip stick alot after i upgradedto a gt3076r turbo then i got a oil catch can it it didnt blow out anymore and also i got a new PCV valve

 

Well this isn't a nissan. And there have been a lot of others on here who have had this problem and its either been the #4 or blown head gasket. The lucky few it's only an intake manifold gasket, but I wouldn't bet on it.

 

this is something that is being experimented with..the engine is deff getting over boosted to cause this but we dont have a for sure thing that the oil catch can works on our cars..im going to be putting one on mine but also gonna have a strong head gasket and intake manni gasket so i wont know for sure whats helping to not make it happen again

 

you do not need to vent it with a 2.8 pulley.

the 12.5 afr without a way of watching the egt's more or less fucked it.

don't bandaid it right now. do the leak down and compression test. find hard proof that the motor is ok.

 

i can grab the specs tommorow from work if youd like. I think it is 180 though. Also, if the lowest cylinder is more then 10% lower you need to do some investigating. And to be honest, dont drive the car. Your gonna just be driving into a bigger pile of ****. stop while yous till have time
