Its worth a shot mate.

I had a friend at work, had a 20valve Toyota motor, that was rebuilt.

The place that installed it filled it up with Mobil 1, fully synthetic from the start. It wouldn't make ANY power, just blue smoke!! Shows how good synthetic oil really is as a lubricant, as nothing bedded in at all

After much bitching with the workshop without getting anywhere, his old man drained the oil, ad replaced it with some cheap mineral oil from Kmart, it was about 10bucks for 5litres. filled it up, new filter etc, and took it for a 4 hour drive, loading it up as much as possible e.g 5th gear up hills, high revs, downhills in low gear high revs etc. Next day, same thing, 4 hours of non stop driving, as much varying the revs as he could.

It started to come good

Two weeks later with the same oil in it, after about 2000km of driving, it was back to normal, and smiles all round

I'd try it mate, serioulsy it should help. I'd get some cheap mineral oil, new filter and give it a shot. It it starts to come good, keep going with it until its better, and then maybe run some Nissan 7.5-30 semi-synth for a few changes

Just seems to me that the bores/rings never had a chance to bed in, especially with the synthetic oil used to run it in. A big no-no

My 2c anyhow......

Well I guess I've got nothing to lose and it buys me some time to save some money ( yeah right ! )

Still, I do want to hear more from anyone else with regards to these pistons and rings so I can get well balanced optinion. At the moment I'm not sure if I could recommend them to someone building an engine.

give it a try mate, long weekend coming up and all should mean you can rack up some serious kms. Chances are it will help, and for the cost ( 'bout 20 bucks worth of oil, and maybe $80 in petrol depending on kms) its well worth the effort

Also stay away from leeting it idle to warm up, turn the key and drive normally as soon as it starts, it might help the process a little quicker (no boost though until warmed up)

Look, there's nothing wrong with arias pistons and rings - provided they are fitted correctly and run in correctly.

By the sounds of it the guy who put the full syunthetic oil for the run in didn't know WTF he was doing. U NEVER use synthgetic oil for the run in.

Try chris32's option, and if that doesnt work u may have to go for a re hone on the cylinders.

Arias are good pistons (most piston companies are supplied their rings by wiesco) so dont believe the BS someone is feedig you.

Actually, I was so disheartened by the whole issue that I've only just started trying to sort things out. What I have done ( you ready for this ?? ) is poured 1 litre of Kero into the engine oil ( engine at operating temp ) and let it idle for 10 minutes. Watched the engine temp rise slightly, heard the engine making less than purring noises and watched the idle drop slightly. I would imagine this level of anxiety would be something like watching a family member being tortured :D

Anyway, I drained the sump and oil cooler then replaced the filter and filled her up with 30W mineral oil and have since put about 200kms on it. Will keep going till I've clocked up 1000kms and then do a comp test to see what's happened ( if anything ).

Next I'm going to try the sand in the cylinder's trick, then flush with MEK ( Methyletherketone ) and stuff a banana skin down each plug hole to build compression :D

Eg. I'm going to pretend I own a holden ( joke.....)

      Need AC Compressor for R32

      By GTSBoy · Posted

      R12 has not been not available for....decades now. Propane is not a great replacement. (I mean, it's a great replacement, but it is a bit too flammable). R134a being the only way to go forward with an R12 system. The design pressures etc, are close enough to R12's to work. The ability to move heat around is close enough to R12's to work.

      Need AC Compressor for R32

      Out of curiosity, what's the reason for converting? I think @R3N3 might have the Frenchy's kit in the R33? I somehow think of you as the ambassador for realistic and clean street-driven setups nowadays

      V35 Overheat + Coolant Boil & Overflow + Engine not Starting

      By V35_Paul · Posted

      careful when running the car after a boil over. Ive heard you can lose enough coolant that it won't show the right temps because of too much air in the system (or something like that). Make sure the levels are good before trying again.  Maybe a mobile mechanic can come have a look with their scan tool ?

      Need AC Compressor for R32

      OK, just for some extra clarity - there is more than one option at Frenchy's. 1. You can buy the whole kit - with or without the actual compressor. The whole kit includes mounts, hoses, condensor, etc. That's either ~$2200 or ~$2800. No surgery required with this option. 2. You can buy just the bracket (~$600), or the bracket with the compressor (~$1200). Either of this or the above option "without the compressor" is if you already have an Echo comp or you are able to source one locally. Whatever the case, in this option, you will need surgery done on your hoses to adapt to the new compressor. When I said "the Frenchy's kit", I meant the whole kit in option 1. It is obviously somewhat more $$ than a $1500 OEM compressor. But if I had to spend $1500 on an OEM compressor, I would certainly consider spending double that to renew and significantly update everything forward of the firewall. Another option is to rebuild your original compressor. My R34 comp is currently dead and I will be most likely doing that to it if the spare one in the shed is also leaky.
