I searched around and got some answers. I have a 90 turbo integra it has stock head studs. I am tuned to 10-11psi. My problem is only under full boost my radiator is filling up my overflow res. But if I drive normal with no boost or little boost it will not fill up. Is this head lift. I havn't seen any with smoke from the exhaust. any info would be great. thanks.

Sounds like it to me. Replace your headgasket.

replace the headgasket, get the head resurfaced and get arp headstuds and youll ahve no problems then.

You may also want to pull some timing. Unless you had it tuned by a very experienced tuner on a load-bearing dyno that can produce detonation like you'd get on the road, then likely it was given too much timing, and the little bit of detonation is destroying the head/hg/block seal.

Pull timing as in Retard the timing?

yes

My tuner set my timing at 16 degrees.

Headgasket is blown, plain and simple.

Honduh headbolts aren't prone to allowing the head to lift. Your problem is you boosted an old engine that needed a rebuild and/or it was fed too much timing.

Haha, doubtful.

Is it overheating? My brother GSR turbo did the same thing. That was after arp head studs, new water pump, new timing belt, headgasket change and dyno tune. It turns out he needed a bigger radiator. He brought a koyo radiator and solve it.

Since everybody said head gasket and it could be, but I just thought I give you something to look into other than head gasket.

mike93eh2

how much total timing you running?

Sounds like a timing issue. You probably either detonated a bit or your cylinder pressures are higher than they should be.

so you are saying that a timing issue is going to cause my car to **** coolant into the overflow res. but not overheat?

it can happen. too much timing will cause too much cylinder pressure under boost causing the head too lift, Ds are worse for it than others, it will push coolant into the resevoir, but be perfect all other times.

Yes.

How?

turbotypeR@SPEC

what radiator are you using? i have seen that happen with the stock civic radiator.changed to a pwr and problem solved.do you have a way to monitor your water temp to see if it is just overheating?

hangac1093

I have a Mishimoto rad. it is just like a PWR but does not cost as much. It is 2in. thick. Aluminum. The only way to watch the coolant temp is the stock gauge. But it does not spike.

A) I hope you mean 16
B) Sigged.

Yea 16 degrees is it. Does it need to be retarded???

SovXietday

No, that's your base timing. You really shouldn't have to pull any timing at all.

Buy ARP head studs, when you replace your head gasket, put the ARPs in. Step torque to 60ft/lbs and retorque after 10 heat cycles. You will not have any issues.

the stock gauge is not good enough.it won't move much until it is crazy hot.find out what your temps are before you tear the car down.

Not in my experience.

However, you may find that one side of the engine takes on a significant change in temperature as much as 30-45 seconds before the stock temp sensor location picks it up. Freaky, huh?
