Well i just finished my b16 rebuilt. got the bottom end bored 20 over, cp 10.5:1 compression pistons, eagle h rods, acl bearings, all arp studs. Had no problems with the motor prior. I took the motor apart when it was cold to avoid warping. I put it all together with a new oem headgasket, torqued the bolts properly. Only thing i can think of is i know there was some oil on the gasket when i slapped it together. I fired her up and seriously dumped all the oil within 15-20 seconds and it definitely is coming between the block and head. Could I have put the gasket on upside down? i didnt really pay attention how i put it on, i just know the holes lined up. Also, im using a 81mm gasket on a 81.5mm bore, could that be a problem?

 

Did you oil the bolts before you torqued them to spec?

 

yes, i used arp moly assembly lube

 

You say you're dumping the oil? Where the hell is it going to?

 

Yes I too would like to know where the oil is going.

I've never seen a head gasket dump oil out of the backside of the block. I'm thinking it's probably going to be your PCV box on the back of your block. The oil is dumping out on the ground, right? Seriously doubt that's the head gasket, and I certainly would not go ripping the head off until you see WHERE exactly the oil is dumping from.

Were the rings properly gapped? Did you make sure to space each ring gap apart enough so as not to have any two ring gaps lined up together?

There's not enough info to really help at this point - help us help you.

 

the oil is coming out of the of the backside and block and yes its going on the ground. The rings were gaped by the machine shop and i made sure the ring gaps were all staggered and weren't in the thrust area. I pulled the spark plugs out though and the cylinders dont have a puddle of oil in them or anything so i dont think its getting past the rings. the thing is that its blowing oil everywhere its definitely wet above the pcv box and its not the filter or pressure switch and I cant really tell exactly where the oil is coming from because when i start it the oil dumby light comes on therefore i don't wanna run it long and nobody is gonna want to lay under my car and look to see where the geyser is coming from

 

This may sound funny but check your oil filter!

Seriously, I wasn't going to admit what happened to me but it seems like the same thing might of happened to you. LoL...

Last time I changed my oil I made a mistake. I did all the normal stuff, drained the oil, replaced the crush washer, pulled the old oil filter off and put a new one on, then filled it up with fresh oil. Well, when I went to start the car something funny happened...

The car started, but for a few seconds my oil pressure gauge registered zero oil pressure. I gave it a few seconds and just as my oil pressure gauge went up I heard a big splash! So I turned the car off and found my garage covered with fresh oil.

Turns out, when I took the old oil filter off the o-ring had stuck to the block. So, when I put the new filter on there and tightened it down, the old o-ring twisted and distorted and caused the new oil filter to not seal against the block. I looked at the old oil filter and realized what had happened because the o-ring wasn't attached to it.

Anyways, I took the filter off, took off the extra o-ring, and replaced the filter and oil. Then it was fine.

Just something to check, from now on I am going to make sure the old o-ring comes off with the old filter! Lesson learned.

 

/\ that will happen everythime!!

 

well that wasnt the problem

 

i keep hoping theres a line or something that i forgot to hook up but im not having luck with that :-P

 

i was helping my step dad work on his civic one time... he changed the oil and filter started it up and it came splashing down from the filter... i took it off to make shure there wasnt a double gasket .. nope.. so i put it back on and tightened it and guess what splash again..

went back to autozone and they gave us the wrong filter.. so check that

 

its not the oil filter, i have checked for the stuck seal... nope. i have change the filter to a different one... nope.

 

ok, im really starting to think i put the head gasket on upside down and its blocking something it shouldnt be....

 

did you make sure the pcv box is hooked up correctly like said before?? double and triple check that

 

my first head removal I had this problem. but we never took the head back out again.. I believe its possible to put the headgasket upside down. coz if it is an OEM, (which I only use) it should have a some lettering that says TOP engraved on the black top peice of the gasket. Now the second time I took out a head, which was my motor, i was even more carefull, in reguards to removing my head. Made sure the gasket is right side up. then torqued the ARP to specs. But did have a little leak seen around the head and block close to the trany area. I checked it was on the vtec solenoid/new cam cap/new dist. seal. I opened up the valve covers again, and retorqued the ARP +5 lbs from recommended. that seemed to stoped the leak. but your leak sounds gigantic, and is comparible with the first head ive done. Its litteraly 2 quarts from the time we started the car to heating it up to running temp. Good luck on yours, I do recommend, taking the head out again, check for the right gasket facing (I would buy a new gasket) and have your head resurfaced. Even doing the helms head removal, its really possible to warp the head with their directions.

 

if you DO take the gasket off, spray it with some copper spray.... works good for me

hopefully i dont scare u, but i blew a headgasket on my h22 turbo, it was spewing coolant into the exhaust and from the block and head right under the exhaust ports. i didnt heat the motor up at all since i shut it down immediately, so i just tried replacing the head gasket.. the car hesitated to start even tho i cranked it w/ the distributor disabled to build oil press. and as soon as i connected it, it still didnt start right away.. upon starting im doing my usual checks and then i hear somethin so i turn the car off, walk back to the front to see oil, spilling out of the same place.. i pulled the motor this weekend complete and drained the oil.... "full" of coolant.... something was/is warped on my motor at least but im tossin it.

 

probably your head gasket is upside down.

 

your headgasket is upside down it should say up on headgasket if you look at it very carefully

 

I still don't see how you can be dumping 4 quarts of oil in 15-20 seconds just from an upside-down head gasket. I was thginking that maybe he forgot to put the oil filter on or maybe the oil pressure sending unit.

well if the feed port for the top half of the engine is exposed, oil will come out under pressure. not like a gravity fed leak. it will spray out.

 

sounds me to as if you may have the head gasket on backwards, not upside down.

 

I have a hard time believing that an upside down head gasket would cause that much oil to leak.

What car is it? In my car there is only one way that the head gasket will fit on there.

You know how much a GALLON of oil is? This isn't caused by an upside down head gasket. Something's unplugged
