i installed my d16z6 head with new arps/ headgasket new dowel pins parts etc.
resurfaced etc.

i cleaned the block very good with brake cleaner and also cleaned the head very good. i re checked the head that it looked very dry when i installed it on the arp head studs and slowly dropped on to the gasket/block.

i put the gasket on and put the arp thread lube on the nuts/washers etc.
b4 installing. and then torqued it to spec.

everything torqued to spec.


after like a couple of hours i set it aside and checked the gasket surfaces etc.
the surfaces at the rear of the engine looked slightly wet with oil?????
WTF????

in Between the gaskets looks like assembly lube wtf slightly wet??????


i thought it was dry???
what happened

 

did you torque the head bolts in the 2 or 3 stage process? or did you just go all out and torque them all to spec in 1 single sequence?

when you installed the arp studs, how far down did you screw them into the block? did you use a wrench to tighten them down? did you turn them by hand til they touched bottom, did you back them off a half turn or so after they touched bottom?

did you install the studs before dropping the gasket on? if so, did you lube the studs before you dropped the gasket on?

 

ok i lubed the arp studs with the supplied arp packet lube. on threads where the block screws into also on the upper part.
i used the allen screw to screw the arp studs in. by hand till it slightly feels hand tight. slightly bottom out.

i installed the arps on b4 installing the gasket on.
then i dropped the head carefully.

next i lubed the washers/nuts upper threads/ then

torqued it to 3 specs and then 60ft lbs.


the motor is out of the car on a engine stand.
i didn't start the car or anything

but i left the motor on the side after like two or three hours.
i took a nap came back to look.

i saw the lucas asssembly lube slightly between the rear part of the gaskets.
and the front side where the motor has passsages?

 

sounds like you did everything correctly. are you absolutely sure you didn't put the gasket on backwards though? people do that on occasion, which causes the oil drainage passages to not seal properly.
maybe you just got a little bit of oil or lube on the gasket while handling it, and assembling it squished it out to the edges?

 

either way he has to take off the head and inspect it all while replacing the gasket

 

i put the gasket on correctly and it couldn't go on or look right if i would of put it backwards, but if im correctly the oem gasket the tap where the serial number or numbers faces up???


maybe i might of have a bit of the oil/lube between the gaskets.
seeeping somehow when i maneuvered to slowly drop the head on.

 

to be totally honest, what I would suggest doing is just spray it with brake cleaner, wipe with a clean rag, spray again and wipe again, then let it sit again for a few hours and check again. it's probably just some residue that squished out when you torqued it, most likely not a leak. no sense in removing the head and replacing the gasket if you don't have to.

if after doing the above you see more stuff seeping out though, then maybe you might want to consider replacing the gasket.

 

yea i assumed it was some extra oil lucas lube from the oil/holes from the head. some at the rear has like holes passages. i could see oil dripage/ at the rear pcv box hole. im sure its slight oil that dripped when i slowly put the head on the block. was clean when i sprayed brake clean but i think thats what happened,

ok i will spray some brake clean in between the gaskets. etc.
see if the oil between the gaskets goes away.

but if its just some residue that got squished out when i torqued it. from the head passages. is it okay to have some slight lucas/assembly. lube on the gasket surfaces???


torqued
and smashed

also i am wondering that is the dowel pins two of it goes in the rear of the engine or the front of the engine???
i think i put it in the back.

 

its best not to have any fluids at all on the gasket surfaces, but if some does get on it, it's usually not the end of the world as it usually squishes out during the torque sequence, which is hopefully what you see now. majority of the time that happens, there are no problems from it.

the dowel pins can only go in two holes. I don't remember if its the front or back, but if you tried putting them in the wrong locations, something wouldn't fit correctly and it would stand out immediately.

 

where Im lost is with the lucas, i could be wrong, but you dont put lucas on the springs and retainers..you should have torq the head before putting cams on which you would put lucas oil on. So was the cams installed?

 

i installed the cams/rocker assemblies all first on a bench b4 i put the motor on. i lubed up all the other things. inside the head. then i cleaned it put it on the block.

then i torqued it. i did put cams etc assemblies on b4 put on the head because i didn't want to turn the cam and if i incase i would bend the valves. idk/??


shoots i think i put the dowels in the rear intake back side???

 

Yeah I'm thinking it is extra oil..as far as the dowl pins being front or back, dohc I think is back of the block. Let me google it to find out.

 

it's impossible to put the dowels in the wrong location, because they will not fit anywhere besides the correct location in the block and head. don't worry about the dowels. I guarantee they are in the correct place.

 

ok i scrubbed the motor with slight water/sponge and a q tip of some brake clean because the engine block was painted.

some paint was removed when i sprayed with brake clean.
but i repeated cleaning the soap/water dried again.

waited like for a while and it don't look wet like before. so im assuming the gasket is good? it looked better than before.

should i be good then???
what if some oil was on the head gasket?

 

you should be good.
I'm surprised the brake clean took paint off though. did you use decent engine paint for the engine? because that's supposed to resist damage from automotive chemicals. I just blasted two full cans of brake clean and compressed air on my head to clean it after some minor porting, and it didn't phase the fresh paint whatsoever.

 

idk it suckks luckly i only sprayd a little and only the small part of paint came off. i used the duplicolor high temp ceramic paint. what kind of paint did u use. i will use next time a better paint.
