I think you will have to get the head off, but sounds turminal to me. Is it modded at all. I know if you use Skunk 2 cams with oem valves the valve heads fall off

.

I have a b16b for sale

its is b18c4 with itr head itr cams with uprated valve springs and retainers and ek9pistons headgasket was done not that long ago with head skim due to it overheating ad it has been running mint but is has been lil bit smokey just after it overheated

What ECU are you using? since you;ll have run it really lean on a stock one!

that would be in the region of 12-1 or higher c/r with a skimed itr head unless the ek9 pistons have been machined in some way?....

sounds like a valve tho, maybe just half a valve broken off/cracked/chipped

i've had it happen to me before,

time to take the head off

pimpinblackcivic · 01-12-2009, 07:16 PM

sounds like its gasket or valve related, only way to work it out is compression test it and start stripping it down

Sounds like you lost a cylinder, you need to do a compression check, the results will probably be horrible, after that take the head off and inspect everything.

well its running a p28 on chrome management and the car has been runnin mint av got thoughts of valve seals and piston rings i have valve seals in the house but i am kinda shi**n my selft about the pistonrings going to strip it on sat morning

EK9turbo · 01-13-2009, 10:19 AM

As others have said, Compression test it. And if you do end up stripping it down then post pics of your pistons please

b16 mini · 01-13-2009, 06:59 PM

this could be your result.........just to prepair you for possibly the worst...

good luck with it,

Jokeshopbeard · 01-13-2009, 07:15 PM

type-r-dunk · 01-13-2009, 07:25 PM

there was a big debate about valve heads falling off with skunk2 cams+springs,

people saying the heads fall off etc DUE to the stronger springs,

i cant get my head around this, how can it happen?

its like they were saying with the stronger springs they will close the valve with to much force....... what the hell are they talking about?

the only way i could see it happening is due to lack of piston to valve clearance as you said.

EK9turbo · 01-13-2009, 09:25 PM

The uncompressed height of valve-springs, seats and retainers would play a part in the forces between the valve head and the seat, but skunk2 have come a long way in the last couple years. The inner springs fitment in the outer doesnt seem as good as say supertech for example but theyre good quality.

Plus you dont see their cams snapping all te time now so theyre probly using better billets. Most of the big name stuff tats for sale is manufactured in china to keep production costs down and initial profit high for the distributors.
