DrummerSteve7 : H23 Boost Build

[F22HB]

Leakdown will tell you much.

[drummersteve7]

still haven't received my leakdown checker.
I noticed I never got a confirmation number.
called harbor freight they never got the order.
so I ordered one today!

I have cylinder compressiopn checker, but I need this leakdown checker.
not exactly sure how to use one.
but it looks like insert into cylinder and other side into air compressor.
guess I will see shortly.
not sure how it tells the difference between valve, rings, or headgasket.

I will know soon. doin extensive research.

[drummersteve7]

and from what i understand:

warm up engine.
leave all plugs in except for one that is being worked on.
secure crank bolt so it can not move.
insert leakdown tester portion
plug other side to air compressor.
start at 0 psi.
open radiator cap
if coolant leaks out, there is a head problem.

so I dont turn anything myself just let the pressure do that as it builds?

[drummersteve7]

ok so looked it up...

few things, please correct me if I am wrong:

leak air through throttle body = intake valve issue
leak air through exhaust = exhaust valve issue
coolant leaks out there is a headgasket issue

and this last one kinda gets me:
Air coming out of the breather vent or PCV valve fitting would tell you the rings and/or cylinders are worn.

seems to be my case... soo yeah.. um shit!

[F22HB]

Leak throught rings is natural, but only a certain percent. My h23a1 leaked down through rings only at less than 4% on all cylinders. Basically the cylinder will hold 96psi when you're putting in 100psi. Also, make sure the piston is at tdc when you check it. You know you're doing it right when the car tries to jerk foward lol. I usually put it in gear and hold the brake tight while it is getting tested.

EDIT: and I did my leakdown when the engine was cold, so 4% cold and probly alittle less when warm. If you have that much air escaping when warm you might have a problem lol.

man pulled this engine roughly 6 months ago.
No time or money for this project.
Just decided to go with a full build next.

H22 full build, gunna boost the wagon in the meantime!

[KeeleDesign]

man that sucks

[drummersteve7]

yah it sucks, but it is life ya know.

I miss boost!

[ONEKLEAN91]

I do this bitch sounded nasty

[dbsharp]

So whats in store for this beast?

[drummersteve7]

fully built engine by laskey racing
GT4088R
top mount manifold
and potentially a nitrous shot.

I wanna see between 600-700
which means custom axles and a LSD tranny, still deciding on which one for gearing.

Nice choice!

[dbsharp]

honestly forget axles and worry more about getting after market tranny. stock wont cut it for that power for long.

[LoDollar92LX]

yup, Spiker fragged like 14 transmissions at 640whp, 4th gear roll ons and all the teeth would fall off.

[drummersteve7]

everything is getting redone.
transmission, axles, complete engine build.

so yes, everything will be considered.
I am tired of boosting stock components, and yes I understand the
trans needs to be upgraded. Synchrotech for the win!!!
