Check and Recheck

The parts for the overhaul just arrived yesterday after dad helped me bought them in Jakarta. I can't even find a gasket kit here! These are the part numbers for future reference.

Piston ring set is for .50 overbore. Also it's confirmed that high-comp rings will fit 8.9 4A-GZE pistons. The ring gap from the top to bottom is 1.2, 1.5 and 2.8mm. Meanwhile bigports should be 1.5-1.5-2.8 and 20 valves should be 1.2-1.5-3.0. Don't quote me on this. I bought a thermostat just to see if my engine likes it as i wasn't using one and it took forever to warm-up.

Aisin makes OEM pumps so even if the box doesn't say "Toyota", it's all good.

On a side note, do your research before you order anything online. Check and recheck your order before you make the payment. Don't expect the seller to know what he's selling. Weeks ago, I asked specifically to the seller for a "4A-GE 16v oil filter sandwich adapter". I refrained from checking myself the thread size on the oil filter although i know there are different sizes for different manufacturer. I got sent an M18x1.5 retaining nut and surprise.. surprise.. it didn't fit.

A simple Google search tells me that i should be getting a 3/4 UNF 16 thread size instead. Should've done it earlier. Since sending the adapter plate back would delay the overhaul progress, thanks to 3/4 UNF being a larger diameter than M18, the nut was rethreaded on a lathe to the correct size so now it fits.
