Did you check the tolerances?
Clio T 314hp c43 AMG
You mean with a plastigauge etc? No i didn't, just matched up new bearing with the original
172 cup, Impreza P1
Did you check any measurements? Big or main journals on the crank.
If Scoff does the mechanicals it must be your lucky day as I didn't think he did mechanicals any more.
I know what you mean about time though, it just takes so long to get everything done on an engine build.
Hope it's not too terminal.

Tbh I didn't see it as a big deal to check the big end clearances as all the internals came from a running engine and all I really replaced are the piston rings as far as tolerance related items go, the big end bearings where just new out of the box and the same as what was fitted, it managed to get through the bedding in process and 2 oil changes before the noise was noticed.
well if scoff no longer does mechanical (I'd imagine he is to busy if that's the case) I may have to call on Andy's services, I had a unit while building the clio and I now no longer have access to it so I ideally need to leave it with someone to sort, plus the money it has cost for transporting the car and what I owe scoff to this point seems like the best option.
And up to the point where this happen it seemed really promising from the messages from scoff, really responsive throttle and eager even before boost was introduced, this makes me want to finish it.
oh and the crank never left the block so mains are not an issue.

What bearings did you fit?
Clio T 314hp c43 AMG
Originally acl tagged but the tag was on the wrong side and would fit so I ended up with glyco.
Trophy Turbo :)
Do NOT regrinding a crank for turbo application.

Use oem renault bearings. Really not a fan of acl my self especially the race series

I'll 2nd that. ACL are utter shite
Clio T 314hp c43 AMG
I was only heading down the acl route because there tagged, as said I ended up with glyco bearings.
The update on this is I have authorised a strip and inspection instead of breaking it for parts, I'm leaving it with Chris and also Andy (over boost) on here who is going to be doing the tear down, I would do it but it would take ages, plus it would need recovering back here and then back up to Chris against I have decided to leave to them.
172 cup, Impreza P1
I can never understand why on here people say acl race bearing are p1sh, yet they are used on every big power subaru build by every respected tuner on engines worth way more than most Renault engines. If they were that bad then why would so many tuners use them?
172 cup, Impreza P1
Hope you get it sorted soon mate.
Clio T 314hp c43 AMG
Thanks mate, me to! Was sounding so promising before it happened ah well...
Yours is looking good! Good luck hope it all goes to plan, glad I'm not the only one that spends years building a turbo'd clio, we are all at it lol.
In Renault engines the tolerances are shite. 3 thou big ends and 4 thou mains FLOL!
172 cup, Impreza P1
Its a marathon, not a race! Lol
172 cup, Impreza P1
Wont help matters. Lol
I wish I could understand what that meant.
It's twice what it should be.
as cupman says mate it takes time...but worth it in the end, im having my own set of issues atm but should be all good in a couple of weeks

I've seen more engines need new cranks after running acl's than anything mate. It seems in some instances the bearing material is harder than the cranks, but I've seen a fully forged engine with a steel crank fall foul of them too. They may have changed the spec of the material now, but they were renowned at one point for eating cranks. The tolerance issues like what dan @sjm has mentioned doesn't help them at all either.
R5GTT, 2L turbo
I tried lots of brands in the drag car over the years, OEM held up the best. The new engine has ACL. They work fine in the high power Honda's. I think it has a lot to do with you're choice of oil. Harder bearings might be more acceptable with an oil that has a lot of Zinc in it like the Joe Gibbs race oils.
Clio T 314hp c43 AMG
The results are in, it was never going to be good anyway, I unfortunatly fitted 3 of the rod end caps the wrong way round apparently they are in effect directional so 3 where rotating the wrong way, its lightly damaged 2 rods and mullered one, this has in turn sent swarf round the engine taking out the cams/rockers and the journals in the head.
its stripped and will be rebuilt and finished by Andy (overboost on here) with the vr6 turbo clio, I really appreciate him taking it on, if it had come back to me in its current state it would be broken for parts as I really wouldn't have the time to sort it!

Bad crack. However andy will do a epic job. Chin up!@@
Clio T 314hp c43 AMG
Been a while, thought I would update this thread, sent my spare engine up to Andy to take off what he needed to rebuild mine, con rods have been checked and machined and head skimmed, engine is pretty much built up just waiting on some new arp bolts in the coming week then the engines going back in, so hopefully will have a result in a couple of weeks fingers crossed.
182cup & 172 racecar
Mine was supposed to have been built properly, on inspection, 3 end caps were on the wrong way round!!
Clio T 314hp c43 AMG
Il be picking this up tomorrow! Can't wait, it finally made 314hp and 268ftlb
A massive thank you to Chris at EFI and a even bigger one to andy (overboost) for taking on the rebuild when the bottom end decided to have a fight for freedom!
