Well Its running and I have heat cycled it afew times.
Still waiting for my new air cleaner to come in this week so haven't ridden it yet.
My question today is when it warms up it's got a pretty noticible tick/knock in the front rocker box.
Is it possilble for the rocker to be hitting the cover with a se259e cam?
Used the SE perfect fit pushrods this time, still have my adjustables to reuse later if I need to.
Also did a cold compression test and it reads 176 psi front and back. Does that sound about right?
Now how about this one, with both plugs out I rotate the engine by the back wheel and when I stop both cylinder plug holes still hiss for about a minute.
WTF, can't be cylinder pressure.
Could it be vacuum in the crank case sucking past the rings? Is that normal?
?????????????????????? opinions?
In the cylinders, you can hear it through the plug holes
That's exactly what my 96 had.
Its only run for 5 minutes in the garage.
Will it come up when it wears in?
Suppose to have 10.5 - 1 comp with a 47 inlet close I think.
Head gasket was 50 thou uncompressed.
Maybe I should have used something thinner.
roller rockers or stock rocker arms ? if roller you will have to grind under the lid's
Ando,
9.7 fuck they advertise at 10.5 with that gasket,
Pricks if i knew that I would have held off and got a Cometic 0.30.
I'll see how it runs on the week end, if it feels sluggy I'll pull the heads again.
Daddy I pulled the rocker covers and all seems OK can't see any rubbing.
TDC lifts are 0.182 inlet and 0.155 exhaust.
Dumb question but the SE perfect fit pushrods go in with the thin taper at the top and the fat end at the bottom right?
Yeah I know but the rear seems OK and the front taps pretty loud.
The pistons are 22144-08, I searched around and the dome is 6cc I think.
With that 0.50 slab of a head gasket that works out at 10,6 on the calculator. gasket compressed to 0.45.
Do you think my 177psi cold cranking will come up when the motor runs in?
Should be closer to 195psi yeah?
Have to confirm the dome cc's
No, checked it cold.
Front is OK when cold gets worse as it warms up.
Lifter bleed down probably 20min - 30min.
Simmac, no i didnt check as its a factory kit.
Going nuts waiting for this filter to come in so I can take it for a blast.
Haven't fired it up again till I can ride it and see how it goes.
I'm gunna run it in hard only because I'm an impatient prick. and see how she feels and sounds after that.
No way I could ride around for 500ks and not make it work hard,
If its still tapping I might throw my adjustable pushrods in first and see how it goes.
Hope I'm raving about how good it is by next week.
Been disappointed with stage 1 an 2 in the past.
Your auto decomps will give you 176 all day unless you turned them off for the comp test. With a 48 close on the cam you will have over 200 psi with acr turned off.
If you have stage 4 with 259E cam 10.5 comp and 48 close as you say you should see 200.or a bit more. Bedding in the rings will add maybe 10 -12 psi. Your gauge may be dodgy. If the motor is assembled correctly etc then you should be OK.
