i have been having some overheating issues with my turbo d.

if you start it up and let it idle it will be fine, but if you drive it it will begin to overheat both while stopped and while moving. had the master tech at my buddies shop check it out and he thought he had it fixed. however, it is still doing it.

is it detonation creating too much heat for the system to handle or headlift? if you need to know anything else that may be useful just ask.

thanks

detonation causes headlift, those pressure spikes will rape your motor. You will most likely need to make some timing adjustments as long as your afr's are in check.

are you blowing coolant into the overflow?

ridin98civic

yes

HG?

Does it only overheat when boosting? Does the fan come on?

if ur head is lifting enough u will leak coolant out of the waterjacket, if ur intercooler blocks ur radiator u will run hotter, u might need to change the coolant mixture bcuz of the turbo. check for liquids under the car.

Change the coolant mixture huh?

mike93eh2

whats your setup? total timing? arp studs? oem headgasket?

ridin98civic

it was overheating when on the expressway out of boost. i have the stock headgasket and stock headbolts.

i am running a greddy 15g at 7.5 psi, intercooler is def. blocking the radiator

reboosted

can you move the intercooler a hair foward to see if that helps at all when driving

your headgasket is blown. its not an issue of a intercooler blocking a radiator LOL. are you using emanage?

what you need to do:
arp headstuds and new oem headgasket.

What Mike said.

Headstuds and a new headgasket will solve all your problems. If you know what you are doing it's a 1 hour job.

How can you just throw out that his headgasket is blown?

He already had a shop do a combustion leak test which came out negative.

My car would overheat on the freeway and my headgasket wasnt blown. It was caused by the engine bay getting heatsoaked from the turbo.

i know because i have tons of experience. leakdowns dont always tell you everything. ive had tons of headgaskets blow because of the headlifting and leakdowns and compression tests were clean. but with internet diagnosing we can only go by what he tells us.

ridin98civic

i am using the bluebox actually, i know it garbage but it was just to get the car mobile, i will be getting it tuned as soon as this overheating is taken care of (tuner wont mess with an overheating car).

p0gi

Yeah and if i would have told you my symptons you would have said the same thing and I would have wasted $50+ bucks on a headgasket.

Before you tell the guy to spend money you should tell him to run some tests so he can try and narrow down the problem.
His symptons sound similiar to mine, but it doesnt mean its the same problem. I suggested he stick a thermometer under the hood and see if hes getting heatsoaked. He said it only over heats once he starts driving. My car was ran on the dyno and never overheated even once. When I left the dyno and was finishing the street tune it started overheating. Anytime I drove the car under a load (up a hill) or drove on the freeway or even stop and go traffic the temps would start to climb. I ended up having to wrap the turbo and manifold with header wrap to get the problem solved.

i appreciate your help via pm p0gi. i am going to test a few more things, before i go pulling the head. i was planning on arp's eventually but i may have to get them sooner.

Listen to him please! We both have high horsepower d-series. My car is doing the same exact thing yours is doing right now! I lifted my head last weekend. BLOWN HEADGASKET! The engine will overheat under boost and as soon as you come out of boost the temp will come back down quickly.

like i said i have tons of experience.. ive owned the same greddy 15g kit he did. THERE IS NO DAMN HEATSOAK FROM THE TURBO. thats silly.

"been there, done that"

i have about 50 headgaskets hanging on the wall to prove it. detonation causing headlift is a bitch, but good thing i found my cure long time ago.

It's a head gasket. These are classic boosted d series head gasket symptoms.

Replace the head gasket and use some ARP head studs. Some times it really IS what it seems.
