I have a :
d16z6 block with y8 head
75.5mm vitaras running .005 p2w
Honda 75.5mm rings
deck the block 0.020"
788cc inj.
All the bearing tolerences are a little towards the loose side but well within specs.
I have been cranking on the motor for about 2 days trying to straighten out my ignition timing and ecu problems.
I never adj. the cranking offset in crome 1.5.3 so have my 788cc inj. being treated like they are 240cc when cranking oops.
My engine started making a high pitch sound. I thought the starter was making the sound.
Changed the starter still making that sound and my engine is cranking over slowly.
So I looked at the valve event timing to see if maybe the head had a valve come loose or something.
I noticed that the valvetrain was barely getting oil up top.
I can smell fuel in the oil. So I drained the oil and filled it back-up and disable the inj. and put some marvel mystry oil and some engine oil down the sparkplug holes.
I tried cranking the engine over and the engine was still making scrapping noises but the engine was starting to crank faster.
I did this for about 10 min. and the starter was getting hot so let the starter cool down for about 30min.
Came back out and crank some more hoping to get scrapping sound to go away but the engine would not crank over.
I figured the starter just needed more cooling. I let sit over night. This morning I tried cranking over the engine and start engauges but nothing.
I'll try switching a starter and see if that helps.
But if the engine is still stuck do I have to take the hole engine out andcget it fixed or can I just pull the head and pull the pistons out and replace the rings?
sorry about the wall of text. ;D
