head lift with arps?

[delsolck94]

i suck at descibing stuff so.... got a f22a 10.5-1 pistons and rods, arps, precision billet t3t4, civic rad. just got the car back tuned on 7 and 15psi. on 7psi no probs yet but on 15 it fills the overflow and overheats. put new thermo in but still same prob. no milky oil either. so could the head still lift w/ arps and not get milky oil? hopfully i didnt leave any info out

btw tuned on dyno dynamics with no probs

Did you toeque them right?

If you head headlift I would believe that in that case oil would leak out of coolant would leak in or both. I would say that your compression level is to high to hold the 15psi at stable level. Which is why at 7psi there is no issue.

I could be wrong I havent played with a turbo yet. Its just a in theory answer to your question

i didnt build the motor had a shop do it. i would assume he torqed them right. he has built plenty of B`s and D`s but i was his first F.

I agree with Darkcloud that if there was lift, the oil and coolant would certainly mix. I think if there was lift, you'd also have blown the head gasket.

I assume your water pump was new with the build?
Perhaps the civic radiator just isn't large enough to provide enough cooling for higher boost.

The arp fasteners are the best you can get, though I am curious as to what brand of head gasket has been used. Deevergote's comment about the civic radiator is more than likely spot on.

Is the radiator cap new? Dual core civic radiator? I'd do a compression check also.

[delsolck94]

water pump was new when it was built about a year ago. rad is a new dual core(oem style with plastic top). not sure on the head gasket. i was thinking it might not be getting the air flow needed or somthing stupid like the rad cap

i have this same issue with mine..except i have the stock 8.1 compression but 15psi it lifts some..but no mix at all just a full over flow and over heating.just change the headgasket and tq them .use a 5 layer headgasket seals better for boosted applications.

you have arps also? 5 layer fixed the problem?

[delsolck94]

the head gasket is oem honda

[delsolck94]

didnt know if pics might help

yep sure did...but didn't help the ring problem lol..oem honda is a good start.they can take a good beating but boost is a hole another category.i have a bisi 5 layer head gasket and arp studs.it fixed my over heating and head lift issue.might do the same for you.

So when it was tuned - it was ran at the 15psi & no problems? The radiator strikes me as being small for the application, - or is this the common radiator to be used when running a turbo?

Just like others have said I think it sounds like more of an issue with heat. More boost= more heat and that radiator does not look like anything more than a stock civic radiator. I would suggest a better radiator.
