i had a b16 in my crx but blew it up.. the rod when out through the block ouch!!!... anyway i take it off and take apart the head... to see if it was still good.. take it to machine shop to check for flatness on the bottom of my head and they told me it still in good condition no cracks... so end up buying a ctr b16b block from n1concepts up in san fransisco... and i buy brand new head gasket .. and torque the head down to 78Lbs.. i put the motor back in the rex and install it... turn it on but the car idles all the way up to 2500rpm and there is lots of water and vapor... (kinda like white smoke) coming out the tail pipe... so i did a compression test and its 240 all across... i didnt know what it was so i eneded up taking apart the head again ...buying antoher brand new b16b headgasket because i tought that other one could of had been defective..when i took it off there was lots of oil and water on top of my pistons.and when i drained the oil the coolant and oil where mixed... so i did think it would be the headgasket.. so i purchased that other gasket.. and put it back together and still deos the same thing.. i dont know what is making coolant get inside my pistons... i mean i got brand new headgasket.. i took the head to machine shop and its good... block came out of working vehicle and no crack sleeves.... and i torqued the head down to 78lbs... Does anyone know what could be letting coolant and oil get on top of my pistons.. Do i have to get a custom headgasket 4-layer? or could it be the valve stem seals on the head? or could my intake manifold head gasket be causing this problem? i check for all the lines to be pluged up correctly and they are.. if anyone could help me out here..please ive had the car sitting in the garage for about 2 months now.

 

Are you sure you are installing the head gasket correctly? right side up?
I cannot think of anything else that would let coolant get an all 4 cylinders.

 

damn i know its a tricky tricky problem but i am positive and sure i am installing the head gasket right.. there are letter cut off from it.. that say UP and all my oil wholes match up... could it be some seals on the head like inside maybe? one thing is for sure though coolant get on top of my pistons as soon as i turn on the car and water vapor shoots out of the tail pipe.. covering the whole garage with white smoke.. damn... any more ideas..

 

could it be my tourque wrench that does not tourque correctly? or do i need to use a cometic head gasket?

 

There are 2 types of head gaskets. One is if you are replacing a good head gasket, i guess like if you were taking the head off for another reason. And there is a second type of gasket, It is specifically used if you blew your previous headgasket. If you use an oem honda gasket you should not have problems. It maybe your new gasket is too thin, or made from cheap material.

Also are you using new head bolts??? they are expensive but if loosened and tightened too many times they tend to stretch . They can be under torqued!

If this does not work you should replace your head. It may have been damaged and the machine shop is over looking it.

 

one thing i did not mention on here was when i took off the head for the second type i used a spare gsr head now instead of the b16 head and still does the same thing... and the head bolts are arp head studs.. and the head gasket is brand new oem headgasket i bought it of from ebay.. it is a 3 layer head gasket...so basically what you guys are tellin me that the only thing that will let coolant and oil into the top of my 4 pistons.. is a head gasket or a crack on the head? any more possiblites of something else? i mean all im doing is replacing the block with a b16b ctr block and brand new head gasket... damn this one tricky problem....

 

Perhaps the block needs to be decked?

 

thats what i tought too but took it to machine shop to see if it was warped and the surface is straight as a line.. the head as well... so dont know if i should get antoher headgasket and or just throw the motor alway becauase im sick of buying head gaskets and taking apart the head.. anyone....

 

If you are getting both oil AND coolant on all 4 pistons, it's got to be the head gasket or a cracked block or head. If it were coolant only, then the intake manifold or even the throttle body could be suspected.

 

i'm pretty sure that ARP studs have a different torque specification than OEM. be sure and use the ARP lube too.

copper spray hasn't failed me. worth a try next time

 

yeah man thats the thing its both coolant and oil on top of my piston.. its not just coolant.... damn i know its not the block for sure.. the headgasket is also brand new maybe the head.. if it has an internal crack? what you guys think i should do take apart the head and take it to machine shop to get it inspected from the inside? or what would you guys do.. buy a new head gasket? or try a DIFFRENT HEAD FIRST? damn i really need your guys opinions on this so please.. i need my car up and on the road... HELP!!!

 

how much do i need to torque down the arp head studs. 78lbs or higher because that what im doing...

 

one more thing thoe if it was the headgasket wouldnt i be loosing compression in all cylinders? because i did a compression test on it and i got 240 all across..

 

bump

 

if you have good compression and your timing is on... then it would lead me to think that you just need to let the engine run and get all the coolant out of the exhaust system.

even a few teaspoons of antifreeze in the exhaust burning off is enough to cause a huge amount of white smoke.

This is the part that i cant figure out, very strange.

Also I agree with jayay allthough i thought u were saying u were seeing it in the cylinders when u pulled the head. If not give it some time see what happens.

 

What are you using for lube on the studs? I just did mine today and used 30w oil and torqued them down to 85ft lbs. Also when you pull the head you normally get coolant on your pistons. Then when you reinstall the head and crank it up it smokes for a couple minutes. Have you tried a leakdown test?

 

no i have not tried a leakdown test how would i do that? and for what cause?anyway i will go turn on the car right now and let it run for 10 minutes see what happens... ill be back.....

 

one more thing is lubing the head studs very important because im not using any type of lube on them.... i torque them down dry to 78lbs...

 

well i just returned from letting the car turned on and car still does the same thing.. i let it run for ten minutes and i clouded up the whole neighborhood with white smoke... i did a compression test again on it and i got 240 still.. one thing i did to check to see if there was oil on top of my pistons was that when i took of the spark plug to check the compression on it.. i dip the oil dip stick to check for oil on top of the pistons and it does have oil on top of it still... could i be getting high compression on it because of the oil on top of it... maybe it is a blown headgasket.... what you guys think.. could i be getting those number because of the oil on top of the pistons? or do i need to get the head resurfaced and milled and internally inspected? what would you guys do...

 

Are you sure it is not blue smoke instead of white? What does the smoke smell like? Coolant smells sweet. A leak down test can tell you if you have bent valves,blown headgasket,cracked cylinder walls,or bad rings.

 

for sure it is not blue smoke because its not gasoline its water and oil in top of my pistons... smoke smells like burned oil really intoxicating and it will hurt your eyes... Bent valves i dont think so because i dont here any weird noise.. PLus bent valves would still not allow coolant to get in top of my pistons... blown head gasket maybe but how its brand new.... cracked wall is a no no for sure... bad rings would let oil into the top of the pistons but not coolant... I had a question one you use a headgasket or you torque down can it be reused again let say for another motor or no? because this headgasket im using now came out of an ls vtec i assemblemed but never got to turn it on.. so what i did was take out that headgasket and put on this b16b motor... so can you use a headgasket twice? or is it no good once you torqued down? because my friend told me that once you torque a headgasket you can reuse even if the motor wasnt actually turned on.. is this true or false? because if it is true than it probably is my headgasket please help with this problem.....

 

Blue smoke is oil
black is gas
white is coolant

Everytime you pull a head you normally get coolant on top of the pistons. I would get a new headgasket to.Are you torqing them down in the proper order and removing them in the oppisite order? I had a car that I installed different heads and head gaskets on and it would never quit smoking. Turned out to be bad rings. The smoke looks white but it has a blue hue to it.It really burned my eyes. Try to borrow a leakdown test or have one done to diagnose the problem.

 

Ummm, I'm pretty sure you're over torquing the headstuds down. I believe the final torque is 62 ft. lbs. First torque is ~22. Are you using the right torque sequence?

 

We use 75 ft lbs with moly lube and 85 ft lbs with 30 wt oil.
