The Toffinator Posted October 14, 2013 Share Posted October 14, 2013 As some of you know i recently blew the glanza engine to bits, and tonight had 5 minutes to remove the sump and have a quick look.Here are a few photos for now, there will be more when the crank etc is out and the head is off.All im trying to get at is WHAT THE FeCK Did toyota think putting these rods in the later 4EFTES, Look at the size of them. My standard 5E Rods are twice as thick, no wonder they failNot trying to scare anyone as i know i had a bigish turbo on it, but these engines can take a bit of power but not for long, it must stress them to death in a short space of time! Also to note the crank is undamaged by the looks of things, there is ZERO play in the bearings and it still turns over so the bearings where fine. It has just snapped the rod like a twig.

Phil Posted October 14, 2013 Share Posted October 14, 2013 (edited) massive pre ignition? crazy high revs? Phil Edited October 14, 2013 by Philm Quote Link to post Share on other sites
The Toffinator Posted October 14, 2013 Author Share Posted October 14, 2013 It was a VF24 At 1.0bar. Excellent AFRs on the rich safe side, timing was pretty safe also (Retarded) And was running amazing for about 6months on the VF24, 4months previous on a TF035 And years before on a CT9. Had done 90,000 thereabouts mix of miles and kms, engine was oil changed every 2-3k with millers or silkolene pro sStill cant find the cause other than stress Quote Link to post Share on other sites
mikey4410 Posted October 14, 2013 Share Posted October 14, 2013 (edited) whats a vf24 compared to a td04 am i right in saying there very similar ? what air/fuels at w.o.t ? Edited October 14, 2013 by mikey4410 Quote Link to post Share on other sites
Gainzy Posted October 14, 2013 Share Posted October 14, 2013 We should have a halloween theme thread of blown up engines my worst bloody nightmare!! Quote Link to post Share on other sites
The Toffinator Posted October 14, 2013 Author Share Posted October 14, 2013 No crazy high revs the redline was 7600Rpm, boost never creeped or spiked, revs where 5k when it went bang, in 2nd!And VF24 Is Slightly higher flowing, they will do 330 while a td04 will do 290 or soAFRs where low 11s on hard boost Quote Link to post Share on other sites
davehart Posted October 14, 2013 Share Posted October 14, 2013 I don't think Toyota designed them with 200bhp and bigger turbo's in mind so slagging them off for the thickness of the stock rods is a bit dumb Stock engine they will go forever or at least a very long time if well looked after. You mod it, you break, blame yourself not the car Quote Link to post Share on other sites
mikey4410 Posted October 14, 2013 Share Posted October 14, 2013 (edited) so u were running about 290 bhp? afr is perfectly safe as hell i think that these engines are pretty strong really but if its 250 or over with standard rods well......

You mod it, you break, blame yourself not the car Not once did i slag it off, All im trying to do is show people what the standard bottom ends are like while everyone thinks there safe for 200Bhp+ And yes a stock engine will go for a while, Wouldnt say it was dumb as i was expecting it, hence why i have built a forged 5e... so u were running about 290 bhp? afr is perfectly safe as hell i think that these engines are pretty strong really but if its 250 or over with standard rods well...... No mate i dont think it was that high, a bar on a vf24 shouldnt be that high, i dont think lol And mabye but not for long, the stress over time must weaken the shit out of them as they were never designed with this much power in mind by the looks of it, just an N/A Motor with a lower compression and a turbo really Quote Link to post Share on other sites
micky boy Posted October 14, 2013 Share Posted October 14, 2013 Madness how thin they are! But at the same time its amazing how much punishment they can take!!! Pluss your engine was well into 80k miles! I kicked the fuck out of it and so did sam lol I think the location of where you live plays a big part on an engine! up big banks every day of the week engine load etc they are only a 1.3 at the end of the day! At least you done it in style Quote Link to post Share on other sites
daniel_g Posted October 14, 2013 Share Posted October 14, 2013 It was a 98 spec FTE i blew up aswell, i put it in my old GT to get it up and running. I didnt even bother to strip it down because it was catastrophic, rod right through the sump lol. TD04 @ a bar on a Mines P&P. Quote Link to post Share on other sites

Luck of the draw mate I think with 200bhp+ on stock 4E's. I've know some to run for years and others to run for weeks Quote Link to post Share on other sites

At least you done it in style I know you did you radged bastard lol, and tbf i drove it a bit mental, and it was tracked... And yeh it was into the 80k marker but there is no wear anywhere on the thing. Engine is immaculate bar the damage it wasnt worn and old is my point, if it was a bit ratty then yeh:P It was a 98 spec FTE i blew up aswell, i put it in my old GT to get it up and running. I didnt even bother to strip it down because it was catastrophic, rod right through the sump lol. TD04 @ a bar on a Mines P&P. Yeh they go with style! This had 4 holes and split the block in many places 5E should put up with some abuse then, you gonna stick the vf24 on that or go down another turbo route? Luck of the draw mate I think with 200bhp+ on stock 4E's. I've know some to run for years and others to run for weeks It should do dave, ARP etc into it so not a basic forged motor, should be able to cope with a lot!! And yeh as i have heard before your mabye right. Some last for ages! Quote Link to post Share on other sites
daniel_g Posted October 14, 2013 Share Posted October 14, 2013 Bog standard FTEs have went at stock boost so it really depends on your luck. And obviously taking care of the engine will prolong its lifespan somewhat. Quote Link to post Share on other sites
mikey4410 Posted October 14, 2013 Share Posted October 14, 2013 i ma running a td04 @ 10 psi. i am hoping this lasts im running low 11s a/f also Quote Link to post Share on other sites
The Toffinator Posted October 14, 2013 Author Share Posted October 14, 2013 You might be lucky Mikey:P And yeh they can go at anything i think unfortunately but yeh definetely maintenance etc is key. Tune also! Quote Link to post Share on other sites
micky boy Posted October 14, 2013 Share Posted October 14, 2013 (edited) For all you know when you've been giveing it death on the track as you been turning corners etc the oil could of been getting pulled away from that outside rod leading to oil starvation etc could of scrod the shell/crank then the fun began of the rod leveing the block haha that will of happend due to wear and tear Edited October 14, 2013 by micky boy Quote Link to post Share on other sites
The Toffinator Posted October 14, 2013 Author Share Posted October 14, 2013 Only teeside mick so no long prolonged corners etc. And honestly even that rod that is no longer intact spins free on the crank, and has no play. It hasnt gone due to wear i can guarantee that! Quote Link to post Share on other sites
jimlols Posted October 14, 2013 Share Posted October 14, 2013 To be fair teesside is alot of right handers with a few short lefts! Quote Link to post Share on other sites
The Toffinator Posted October 14, 2013 Author Share Posted October 14, 2013 Yeh but no long corners where oil surge is a problem, there is only one and its not a fast corner lol. Big open tracks micky has a very valid point Quote Link to post Share on other sites
micky boy Posted October 14, 2013 Share Posted October 14, 2013 Yeah man it was just a thort and something to think about with your new engine! Baffled sump Quote Link to post Share on other sites
funny onion Posted October 14, 2013 Share Posted October 14, 2013 Mate! Bad times! Feel for youJust as a side note, an afr reading alone doesn't mean an engine is running "safe" because it's hitting 11 on full boost. It's still critically important that the ignition timing is correct through the rev range. Mine was happily rich on full boost and it still melted all the pistons because it ran hot for a number of reasons. Anyways hope you get that 5e in it soon and get it back running Quote Link to post Share on other sites

funny onion Posted October 14, 2013 Share Posted October 14, 2013 Aye I don't doubt you had it set right, just saw a few other posts and thought if mention it. Sometimes it's just bad luck though I think still don't like to see it happen to anyone Quote Link to post Share on other sites
