Kristian_Wraae Posted August 6, 2016 Share Posted August 6, 2016 I bought an Aristo 2JZ-GTE VVTI to convert to VVTI. The engine was supposed to be a 65.000 km unit (somehow they all are......) Anyway looking more like a 265.000 km unit and the oil pan contains metal shavings. How much metal would you expect there to be if nothing has broken? Nothing? Half a tea spoon? I'm filtering all the oil now. I'm of course taking the engine apart - so I'll know in a few days how the bearings look, but what do you think?

Kristian_Wraae Posted August 7, 2016 Author Share Posted August 7, 2016 This is the amount: It is mostly rusted metal. Is this normal? Link to comment Share on other sites More sharing options...
evinX Posted August 7, 2016 Share Posted August 7, 2016 Rusty metal from inside the engine? id be worried. any shaving should of stuck to the bolt. does the oil have metal flakes in it? Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 8, 2016 Share Posted August 8, 2016 Looks like it might be sintered metal from the oil pump rotor. Strip the pump if nothing else is obviously knackered. Link to comment Share on other sites More sharing options...
Kristian_Wraae Posted August 10, 2016 Author Share Posted August 10, 2016 I'll take all bearings apart and put a new oil pump as minimum. If I find anything that looks knackered it'll be a complete rebuild (and a good excuse to go stroker....) Link to comment Share on other sites More sharing options...

You are into a full rebuild if you are looking to do that! Link to comment Share on other sites More sharing options...

Of course you can argue that changing a bearing that is not damaged is not needed. If there is sign af damage it is a full rebuild. Link to comment Share on other sites More sharing options...

Kristian_Wraae Posted August 10, 2016 Author Share Posted August 10, 2016 Dodgy territory in my book but im no pro! /QUOTE] What do you mean? Last time I got the bearings from Toyota - the right ones according to the markings on the engine and checked all tolerances with plastigage and replaced all the rod bolts with new ones. I agree that you don't replace a broken bearing from say a rod knock because the crank shaft will be out of round. But if nothing is broken you can replace the bearings although one might argue that it is not needed. I just think that if I already have everything take apart to check them I might just change the bearings since they are not that expensive. All bolts must be replaced anyway, Link to comment Share on other sites More sharing options...
np89 Posted August 10, 2016 Share Posted August 10, 2016 So at which point you would surely just rebuild the whole engine given the bolts and gaskets are not reusable? Link to comment Share on other sites More sharing options...
