Re: OST-093: My, My, Mystery

Is it a trick of the camera, or does the forged piston have a little less clearance for the oil squirters? If you have the forged pistons ceramic coated (skirts & domes), assuming that also changes the piston to wall clearance. I think ( bad memory) that someone told me to add 10 thousandths whe...

Re: OST-093: My, My, Mystery

The first 4A-GE I bought was from a 1987 GTS coupe (built in 12/1986 from the VIN). It also has those untapped holes on the head (for the FWD stiffener bracket).

Re: Anyone knows the name of this hose and the part #?

I suppose it's better to have the return hose running from the catch can to the intake, than to just plug up the fitting on the intake and vent the catch can? Like the intake is drawing air out of the crankcase, which is necessary?

Re: Anyone knows the name of this hose and the part #?

That hose is for venting the crankcase gases. The 4AGE hose dose not have a PVC valve in it. [Positive Ventated Crankcase.] It is not a special hose! Any hose with a tight fitting ID can be used as a replacement. Does air ever get pulled into the head through that hose? Just wondering, as the 4A-FE...

Re: 4A-FE pistons question

The 4A-FE rods are bent. Probably someone hydrolocked the engine. I use the block as a mock-up, since my wagon never originally came with a 4A-GE of any kind, and this 2nd gen 4A-FE block has a notch along the oil pan like my original 4A-FE. I guess I should clarify, I measured the bearings in the b...

40mm rod bearings question

I'm posting this here because it's something relating to the 4A-FE and the early 4A-GE. Both gens of 4A-FE rods and of course early bigport GE rods have 40mm big ends. But the bearing part numbers are different. Any ideas why that is? Mark 1 bearings used as examples. 4A-FE: 13041-15030-01 (supersed...

I'll never understand why aftermarket companies (like Fel-Pro) haven't made a proper rubber oil pan gasket for these engines. I found this company that makes silicone oil pan gaskets.

Re: Dumb question time, of wrist pins & modifying pistons

Thanks Jondee. The rods I'm thinking about this for are Honda, which all use press fit wrist pins.

Some material is shaved down on the big end to make it narrower...

Dumb question time, of wrist pins & modifying pistons

This is probably more of a general engine question, although the 4A-GE uses both types of wrist pin attachment. From looking at parts diagrams, it appears that the early 18mm press fit wrist pins are pressed directly into the steel of the con rods. The later 20mm floating wrist pins ride inside of a...

I'll have to remember these mods for the 7A-GE I want to build. Speaking of oiling and mods, would it be worthwhile to smooth out or polish the inner section of the block behind where the oil filter sits? And to radius that hole where the oil flows out and into the filter?
