Alrighty. Engine is out. There's a coupla progress piccies.
Some bg info on the setup
Standard s16 crank, s16 standard rods, s16 standard bearings, wiseco forged pistons 86.5 (remade with same compression height 39.1mm as standard), deck skimmed once (not sure how much, might be able to look it up), and rebored to 86.5mm.
PS: I'm no expert on this but am learning as much I can, so go easy.
I took some measurements of what came out...
Crank thrust end-play
Acceptable range .07 - .27mm
Actual 0.11mm - is good. (I have new thrust bearings anyway)
Mains (60mm standard) - 59.97-59.99 - No ovality.
Big Ends (50mm standard) - 49.99 - No ovality.
Crank Bearing clearance
Can't measure really... don't have a bore dial gauge or calipers with round ends to measure bearing shell thickness...But will be replacing them with standards and will torque up the new ones and plasticguage it and fingers crossed the clearance is spot on...
Piston to deck clearance - Measured .7mm, so I'm guessing it was skimmed .3mm?
What's the standard clearance for this, 1mm? Is that right (calculations below, correct me if I'm wrong)...
Std centre of crank to deck height is 235.1mm
43mm (half stroke) plus
152mm rod length centre to centre plus
piston compression height = 39.1mm
Standard deck height of 1mm.
Now, I was running a 1.3mm gasket, and for the rebuild I have a cometic 1.778mm (0.7") gasket, so 0.478 higher.
The thought was that with this rebuild to increase compression with decking the block 1mm, but now it looks like I should only do it .7mm (to get it flat/neutral at TDC) - but now I've gained extra height in gasket (which means quench height is increased), not entirely sure how much to deck it...
This may sound dumb, but if I have a negative piston clearance (pistons protruding above the deck), won't it start hitting the gasket?
How far do I deck it with the thicker gasket to get the higher compression and perfect quench height??
