Default just dropped in new motor and all the coolant in the oil pan

i obviously screwed something up....first let me start by saying the motor WAS NEVER STARTED...i dissassembled the motor so i thought i could reassemble it, turns out i am a idiot...

so heres the story, i just got my new shortblock and i put the heads on and put the motor back together and dropped it in this week

i put coolant (only had 1 gal)and oil in a couple days ago and today i went up with more coolant and strated putting it in after another gallon and it wasnt full i startyed thinking something was wrong,

then checked the oil and it was dripping.....i IMIDIATLY drained the oil...as soon as i pulled the plug STR8 coolant came out about a gal n a half then oil then alittle more coolant... there was also a gallon left in the rad .. i drained it also...

is the head gasket not sealed? coolant/oil line crossed???

also, i torquerd the oem headgasket to the new arp directions...(85ftlb)

im hoping to god that i crossed a coolant and oil line somewhere but i was looking and couldnt see anything wrong, im gonna take the mani off tomorrow... i was looking from whart i could see and nothing seemed wrong but i was sooo pissed i couldnt stay up there any longer...

i was thinking maybe a turbo line was wrong bc i wasnt sure which was which but i dont think you can get it wrong..the oil lines are bolt on and the coolant lines are clamped on barb fittings(gt35r perrin kit) right???

i cant seeing the headgasket leaking that bad....also, the top coolant tank next to the intake mani filled up and stayed full for alittle while then it sounded like a huge bubble and it all went, for it to of went str8 to the pan like that there would have to be a HOLE in the head gasket


this is my first motor build...what else could it be???

please hold the comments on my stupidity...im a NOO'B to building motors

Sorry to hear that. The lines for the turbo are correct. Post pics of all the coolant and oil lines on top of the engine, and we can have a look. If they are all in order, then yea it is something with the head gasket.

Maybe you switched a coolant line with the turbo oil return line. Only thing I can think of besides something internal.

could it be something wrong w/ the block/machine work? also i didnt think you could install a head gasket backwards...it only goes on the pins one way...atleast thats how i remembered it...i flipped it both ways b4 i put it on to see im pretty sure...

i would say the head gasket is the first thing to check i am also biulding a motor but form all the people i have talked to i have never heard that happening but as much as is going in it sounds like a bigger problem then that maybe a cracked head?

the oil return line off the turbo i ran straigh down to the line that had the small rubber hose on it with the 2 wire clip clamps on it.... im going up tomorrow to double check, i looked under the manifold from what i could see for like 5 minutes and left...i cant work when im that mad...if i coulda kicked my self in the balls i woulda...lol


i dont think its a cracked head, the car was running perfect when i pulled the motor and werent touched till reinstall...

also if it is the headgasket...can i try just retighting with the motor still in or do i need to change the headgasket completely?

also i didnt have my heads decked....i didnt know i should have untill i already had it in the car lastweek

Did you have the block halves split? I would think so because you mentioned machine work. There is a very good chance that the orange 'O' ring slipped or was not installed when the halves were put together. This would cause your problem because even if the head gasket was installed backwards, there would be an oiling issue not a coolant leak.

yes they were split...i will be really pissed if thats what it is...im about 99.99 % sure the headgasket is right, i made sure EVERY hole lined up and from what i saw it only went one way with the pin holes lined up..right???

The head gaskets can be reversed but the oil hole would not line up causing a severe oil leak when started.

an OEM headgasket can be installed backwards. it will fit on the pins either way but one side will slightly block/not line up perfectly at one area on the water jacket. describe your torque process and sequence. OEM sequence calls for a specific torque, then backing it off to zero load, then a specific torque again, follwed by a final torque to yield by a specific degree. Use oil on bolt threads. don't re-use headgaskets if you find they are on backwards/take the heads off.

The easiest way to find out is to drop the oil pan and remove the windage tray, then add coolant and see where it is coming in from.

ill do that with the oil pan...thanks...

i misunderstood the tightening procedure, i think... i just did the sequence (i def got that right) in 25 ftlbs then started the sequence over to 55, then to 85... i didnt go tight then back them completely out to no load then tighten again...also i used the ARP lube on ALL the studs/nuts...

can anyone else CONFIRM that if the gasket is on backwards it would be a oil issue and NOT coolant... now im double thinking myself but i know i layed the gasket on the block and head differant ways and lined everything up......i just dont see myself doing that...

i will def take the oil pan off tomorrow and add somemore and see where its comeing from..

do you guys think i should add more coolant and see with the pan off or just start ripping into it by taking the manifold off to double check ALL lines??? i was thinking to stay away from putting anymore in there,its already bad enough

what should i do after i fix the problem to get the coolant outta there?

I feel your frustration and at one time or another we learn from our mistakes. It is a lot of work to start pulling parts, but the pan is the easiest with the engine installed. If you determine that it is a gasket or a case issue, then remove the engine as an assembly instead of a part at a time.

you can look at the marks on the head gasket to see if you got it backwards. look for the 2 or 3 dashes/cut outs/whatever you want to call them. If both gaskets have them on the front or back of the engine, one is in backwards.

Check the small rubber hose for the water way across the top of the block is connected to the bottom of the water header tank, and not to the cam breather for pistons 1 and 3.

Hope that makes sense.

Its a common mistake i have seen people make here in the Uk, they get the breather pipe and water pipe crossed over.

This is the reason for forums...... ^ I did not think of this.... It would stand to reason for the rapid coolant drain to the oil pan. The other possibilities would be a much slower process.

now that would make sense...HG would to but, come on...

cracked block, block half o-rings, etc...are small and wouldn't leak like this without running the motor for quite some time. If I understand, the motor hasn't started yet.

100% sure the motor has never seen a hint of fuel or oil pressure...the fuel lines werent ever even hooked up yet...

im hoping its the linjes on top..im going up there now to take the oil pan off and the intake mani and look it over...

i dont think the breather is wrong as i could see that with the manifold on...but ill still double check

maxwellpower~ are you talking about doing this with the motor installed? im confused on what your telling me to do/look for..i see the cut outs on the headgasket(i got my old one)..are you saying the shhould be opposite of each other like one side theyre on the front other side on the back of motor?

ill get back to everyone later tonight...crossing fingers and praying for a x'd line...


also...i was just looking at pics of head gaskets and blocks...if the head gasket is backwards the hole at the top left corner wouldnt line up at all...theres no way i did that...i was thinking before after reading the replys(which are GREATLY appriciated)that if it was backwards it would just be off alittle...after looking i just dont see me doing that as i clearly remember laying the gasket differant ways on the head/block just looking at it and it would lay both ways on the pins but it wasnt even close lining up the hole at the top..right??

anyone got a pic of what the gasket looks like on backwards?

I just did a test fit of a bare head and block with the head gasket flipped. Everything lined up except for the oil passage port. The coolant holes were slightly off but in no way close to the oil return passage. I say NAY to the head gaskets causing your problem.

welp...just got back from the garage and i dont think a line is crossed...i took the manifold n fuel rails off and there was coolant on the passanger side injectors...i then took off the valve cover and there was a significant amount in there...

all the coolant lines ontop are right...im pretty sure..

theres ONLY 1 oil line other than the small metal line that runs over the pass side head that goes to the turbo oil line... which is the crank case vent on top of the block right??? that goes from valve cover to valve cover and a small few inch hose down to the case in the center...

everything looks good..the 2 lines going down to the water pump and the lines going to the heater and to the TB all ok and coolant only....i traced every line i could see on the block...all the oil lines are metal

i couldnt get the oil pan off...how the hell do you get the 2 back bolts out? i dont have small swivel extensions for the little drive..nothing i had avalanble at the moment would work. so scratch that...i couldof drove and borrowed tools and prolly got it but after what happened next i figured i didnt need to to see whats wrong

heres what i did after i had the manifold and pass side valve cover off....i connected the 2 ThrottleBod coolant lines together, plugged the coolant like that goes upto the tank(next to mani) and put the main rad hose on up in the air not connected to the Radiator ...unplugged the oil drain and poured some coolant in...it took alittle while but before you know it coolant started coming out and when i BLEW pressure into the rad hose it started spewwing out the valve cover right at the back corner closest to the firewall...the harder i blew the more came out and as soon as i quit blowing it quit...

what gets me is w/o blowing its still going str8 to the pan but w pressure its coming out the cover....

so ill be pulling her back out this week.....

id say its easier to pull the motor than to try and change the head gasket with it in..correct???

it still STUMPS me how without ever even starting it and torqueing it down it can just run threw like that...i woulda never thought that was even possible without some sorta pressure other than gravity

also, as far as the head gastes being backwards...i dont think they are, the "2 cut outs" are on opposite sides the passangerside ones are towards the back of the motor and the driverside are towards the front...as they are on my buddies sti(as he claimed over the phone,but he wasnt 100% sure)

i forgot to mention there was NEVER spark plugs put in either and not a drop came out there...if that helps?

Without a swivel, you should unbolt the motor mounts and the pitch mount, raise the engine with a floor jack, then you should be able to get to those two rear bolts.
What ever is leaking coolant is bad! I would try to trace it to the source before pulling the engine because after that it is guessing.

i honestly did think about doning that but i figured last resort...also, with the pan off, what could i possibly see?

so are you suggesting it still might not be a head gasket???

im a nooB to building motors but i just dont see how its physically possible to torque the head down and there be a leak so bad that it goes right thu

Do you somehow have the turbo drain line attached to the turbo water line?
