Quote from: thetyrant on December 21, 2023, 08:39I didnt mean dont use a oilcooler, just dont use the one you have there with bits of engine inside it as ive mentioned before its best practice to NEVER reuse an oil cooler from a engine thats lets go as you can never guarantee to get all the bits out, some get lucky and they stay in cooler but its just not worth the risk, ive seen it a few times in the Evo scene i used to be part of, everyone that reused the cooler after flushing it best they could had engine issues again.Lower power with the 1zz yes but hopefully you could beat on it all day long without issues and have some seat time try to gain time elsewhere, with the aftermarket ecu/decent mapper and breathing mods i dont think it would be that far behind your restricted 2zz setup, also its going to be a lot faster than a blown up 2zz I would also question the tune on the 2zz setup which is another common part to all the engine issues, i think read somewhere one here he was using overfueling to restrict top end power and help cool the engine?, that could well of diluted the oil/lubrication etc, if you have not already and you still have some i would get oil analysed to see if its heavy on fuel.
Quote from: Alex Knight on December 22, 2023, 13:19@jvanzyl I will defend MY 2ZZ to the death, though I'm obviously not unaware of the reported failures on track. I can only speak to my experiences, but my engine has been the most reliable of any car I have had, ever. And that includes daily drivers.But... as soon as I read the 130-140C oil temperatures above, across multiple engine failures, I immediately put 2 and 2 together. To me, this is very obviously your issue. Those temperatures are literally catastrophically high to me.
Quote from: JB21 on December 23, 2023, 08:26Didn't realise you were peaking over 140°c oil temps, that's insane with a cooler and is surly the issue. For reference my non oil cooler 2zz can run for 20+ minutes at 10 tenths and it never reach 130°c. All I have is a huge mishimoto radiator.
Quote from: jvanzyl on December 23, 2023, 09:34I have a thought/ question. Is there a difference between the water pumps found in a celica sourced engine vs a Lotus engine? Same goes for the thermostats?
