I have a fully built gsr block and head. I have been having overheating problems and been finding oil in my coolant. I thought it could have been the head gasket so i pulled the head yesterday and nothing was wrong with the block or head gasket. Before doin any of that i did a compression test and it read in the 150's all the way across. It always had enough coolant and the fan always kicked on whenenver the car started and it still overheated. Could the sleeves be cracked? Would cracked sleeves cause oil to be in the coolant? The head was slightly warped so i sent it off to get shaved, but i dont really know what else to do.

Any help would be really appreciated......................Thanks alot guys

If the Head was warped it sounds to me that its possible a bit of oil could leak into the collant jacket and mix it or the other way around the collant into the oil. also i almost garauntee that is what it is due to the car pushing exhaust into the collant chaber is not allowing the coolant to trully cool down. i bet the car would not overheat while driving right just idling

it would overhead driving right. just cruising at around 40 it would still overheat. if the car sat long enough at idle im sure it would have still overheated

How off was the Head warped that is a huge factor you pistons can stil make compresion but if the head was warped in just the right spot this will allow for oil coolant mixture. Im more curious to how the head got warped first was the car running hot before.

the head wasnt off that much just in one spot. the car started running hot when i bumped up the boost to about 15psi, so i bought a bigger aluminum radiator and cooling fan. i had to replace one of the radiator hoses after i noticed that i kept using alot of water. i would have to fill it up like every other week or sometimes every week. even after replacing all the bad hoses it still it still seems to be getting hott

there is a small change that it is a cracked sleeve im leaning more toward the head at this point did you ever get collant in you oil you just mention oil in your coolant not only that do you have a breather set up on the car to allow for crank case ventilation that way your not building up alot of pressure in the crank case.

civicboy1128

no i checked that also. there was no coolant or anything in the oil. i couldnt really see anything wrong with the sleeves either.

yeah, sometimes the cracks int he sleeves are so small though but in any case get the head fixed and see then, the only other thing to do is get everything back to gether and start up the car if it begins to overheat let it cool down for a minute then remove the radiatior cap then start the car up again wait for the temp to come up and watch the fluid in the radiator if there is bubbles coming through the radiator, there is a good chane of a cracked sleeve and the pistons are pushing the compressed air into the coolant wich will cause the overheating otherwise the head being a bit warped caused that same exact issue and then you problem solved. its hard to say without the car running what it is for sure get the head on and do these test only if it overheats again but other than that good luck bro. and remember Go Boost or Go home.

well i havent seen bubbles in the radiator before so i kinda doubt that the sleeves are cracked, but thanks for the help anyway man

Just curious,
what thermostat is in there and what kind of cooling fan do you have?

civicboy1128

just took out the thermostat today. its stock. i bought a neukin 3'' radiator with the pusher fan already on it

sounds to me like when you turned the boost level up it lifted the head. What kind of fasteners were you using? Stock headbolts or aftermarket studs?

civicboy1128

arp head studs

Evil-EK

did you break the motor in and then go back and re-tq the studs?

civicboy1128

yeah the motor has been broke in for a while. would adding a ramhorn manifold cause the whole problem? cause i was just thinking that it never overheated with the cast manifold i had on it but it first started doing it when i put on the ram horn. i dont really think that i could cause that much of a difference in temp.

I'd double check that first. But keep in mind just because your headgasket "looks" fine doesn't mean it is. Honestly I'd try pulling the headgasket, buying a new one and spraying it with copper gasket sealer and then re-torqueing the head down again.

yeah, i already pulled the head and checked it. it was slightly warped so i had it shaved and i should be getting it back today. i wont be putting it back together until probably about friday cause i have some skunk2 turbo cams comin in and i figured id just put it back together all at the same time. i also wrapped the manifold and downpipe to get rid of some of the excess heat under the hood

First off...apparently those turbo cams are less effective than their regular cams in turbo applications lol...

Secondly, please get a new headgasket, spray with copper gasket spray (let sit till tacky) and then re-torque the head down.

Make sure you torque the head down to spec, let sit for like 15 mins, loosen nuts, and then re-torque a second time. This is because the new headgasket will compact and you could still have a leaking problem if you don't re-torque

I have seen sleeves leaking
its possible
