So this happened... lol. Its not like de-pinning the ECU. Any way to get this thing open?EDIT:::: Figured it out! Was looking at it from the wrong side... heres how you do it.

Well I did a leakdown test today and every cylinder was at 20-25% according to the cheap HF leakdown tester I got. I didnt hear any air in the intake or exhaust, even on the valve that I thought may have been bad.

Im 90% sure that the light could be seen all the way around, its just the angle I took the picture at that makes it hard to see. The guy I got it from said that It was recently rebuilt (which I think it true because I found some assembly lube inside it). It was only that 1 valve out of all of...

Hey I was having issues with compression previously (cyl2) and it lead to bent valves. I replaced the head and its now fixed. Compression is (1-4) 170 170 170 140 .... I know 140 is still ok, but im confused why one is at 140. (Added a cap of oil and there was no change)When I got the head I...

Yea sorry that's what I meant ^__^

Is there a way to simulate the isc in ecuflash like you can in link? Haven't found a definitive answer. Thanks!

Assuming you dont feel like disassembling it?

sounds like it!

If it was something wrong with the valves wouldnt the compression be low??

Do a boost leak test. Same thing happened to me yearssss ago. Also im assuming you have gaskets between all your exhaust mating points?

I did a tbelt and found the balance shaft belt snapped. I didnt check timing prior to removing everything so im assuming it may have skipped a couple of teeth.

Depends on how low you want to go...That will also determine if you need a camber kit or not

Cant he just get a stocker t25 or 14b and get that running instead of higer end 20g's etc that wont even push 10psi on stock 420 internals?Oh, and youd also need to tap the comp housing or intake pipe next to the turbo to anser your original question

Yea, I just dont want to spend money on a new head and then find out it was ok lol. I cant take it apart and leave it apart so I cant really even check other than what ive already done

Well I have a compression tester and I just took the one way valve out and hooked it up to the compressor. When I do that it holds NO pressure, and immediately goes to the throttle body. Only reason I dont think its a HG is because there was no movement of coolant in the thermo housing at all...
