Engine 1.0 - Toyota Carib, 1.6 L, 1988
Update
Fuu, it's okay. My own pistons turned out to be from Silver Topa. =) So that the repairs are more than normal, they are what they should have been in the engine.
We collect quiet spare parts for the capital.
Finally send me overhaul piston 0.5 for GE Black Top and rings.
Opening the box, I was unpleasantly surprised. They have nothing to do with their own pistons. We look at the photo.
The grooves for the rings are also at different heights, but it doesn't matter, they should work
Part-number, already wherever I could check. According to him, these pistons are normal, blacktop
The rings - the partner for which he ordered, turned out to be outdated. But I think it's okay, they'll do.
My hypothesis.
I hope that over time, the design of the pistons, especially the repair ones, simply changed, and those pronounced ebb tides for all five valves were simply removed due to their uselessness.
As far as I remember, when the timing belt breaks, pistons with valves are encountered in any case. And the geometry of the piston crown was dictated, for example, by the risk of a "fist of friendship" when the valve hangs at high revs.
And for some reason, the designers abandoned this later. And those pistons that came to me will normally work on black metal.
The hydrach also came, thanks to TYSON84 . I hope that the fact that I screwed myself up without seeing that it was with Silver Top and not with black metal would not hurt to install it on the car ... But I doubt something, eprst ... No photo, in the garage.
In general, we live like that, in a corner and in a closet. They promised to drive them out of the apartment with all the hardware, and for damaging the bathroom. =)
PS
And yes, my article about Toyota 2000GT came out, which I just fell in love with. here - www.apex.ru/apex/ru/articles/o_6645
Price tag: 8 000 ₽yeah, we could have changed the design. you assemble, put on the timing belt, turn the engine and you will understand whether they fit or not) will rest against the valves or not
They sometimes resist because of the wide camshaft, when the inlet starts to open long before the TDC, and the outlet closes far after. But these ports are very good, judging by the pictures.
