The div who owned by GT before me melted cylinder 3.

Spec:
- Standard engine, turbo & mani
- HKS actuator set to 1.1 bar
- JAM FCD

Ringlands went on cylinder 3. little wonder...

my car had all sorts of problems when i first had it

4efte
uprated ct9 mani
ct9
hks actuator

ran the car at 0.75 bar was thrashing it with 5 people in the car

and it had been burning oil.

piston rings were fuubarred

snapped a big end bearing into a bout 20 pieces on rod 3 oh dear !!!

Just recently brought a 96 Glanza V fully forged with a hybrid turbo running 1.2 bar boost. Had her 3 days and the turbo seals went, had the turbo rebuilt by turbo technics, put her back together and then 3 days later came of an island in 2nd changed at 4000rpm into 3rd and *BANG* crank gave way and put a nice sizeable hole in my sump and covered the A5 in bits of engine and oil :( wooops! Starting to wonder if ive been done over! O well I stil love her! :p:p

Surprised not to see a post from jezza here yet lol.
He was running a ct9 hybrid set up with all supporting mods Inc. Blitz access but was running it on regular fuel, took it to a dyno day where the power run was done in 3rd gear (not sure if this would have any adverse effects or not) but there was some smoke and lots of oil.
On closer inspection a lump of the 3rd piston had came off and welded itself to the bore wall and the rest of the piston was split.
I'll give him a shout for some pics.

well ive been having alot of fun with my car recently.

was driving down the motorway when randomly the oil light came on so i looked to the left to pull onto the hardshoulder only to see massive cones blocking it off so couldn't stop!

when i got to the closet place to stop there was a massive bang from the engine bay and i have later found out that i have snapped a conrod and comepletely fu**ed the engine :(

i wouldnt mind if i didnt look after it but i check my fluids every day and i understand that the oil light only comes on very low at 7-9psi so with having what i can only describe as a random leak of oil i am now in need of a new engine.

what makes it worse is that my current car is now a mk1 1.0 litre pug 106 with 4 gears lmao

Just FYI - if the oil light comes on in a starlet, it's pretty much already to late. Later toyotas came equipped with a low oil level warning light which is FAR more useful, unfortunately for us, too little too late.

Seems to be a disproportionally large amount of failures while running a jap 'premapped' ecu, blitz, jam etc

Can't say I'm surprised.

Haven't quite had the turnout I was expecting, for anybody who reads this and subsequently has an engine fail can you please take photos or get your mechanic to take photos during the tear down phase! This is the only way that we can really learn from other peoples failures.

4efte
tong hybrid
emu ,running 1 bar
oil....motul 10w 40 turbolight
decat and exhaust 2.5 inch
was flooring and aferwards heard a clicking noise,and cylinder 1 and 2 stopped working but fire was coming...when i checked the oil level ,to my suprise there was only about a litre of oil:(
top up oil and still had the same noise which seems coming from the head..
the engine was stripped,and nothing was wrong :confused::confused::confused:change the bearings,[main and connrod],also redo the valves and change the valve seals
car works fine now......
[/ONE ADVICE ...CHECK UR OIL AND WATER EVERYDAY..:)

Nice idea dude. I didnt get any pics of the first engine but ive got a few of the forged. You mentioned std in your first post but o well. Looking at other peoples misfortune usually makes me not feel alone when mine lets go.

First engine, bog stock, started knocking loudly one day then just died. A pull down revealed 2 bent rods nearly all big ends shagged and 2 cracked pistons. Was running a tuned unichip atm.

Now it gets fun....and expensive.

forged 5efte, std headbolts + 1.2mm composite gasket. Autronic sm4 ecu (CR 9:1 300hp atw with gas). The car is raced heavily in drag and circuit at this point for 2+ years so the risk of failure goes up quite a bit. After a half throttle burst in 3rd gear I hear a bang and start loosing power. Pull down reveals #4 big end worn, blown headgasket between #1 and #2 and a chunk missing from the head.

Rebuilt with a 2.1mm composite gasket + 10mm arp studs CR now 8.3:1 + smaller turbo and 28psi + gas gave aroud 330hp atw. 1 day after tuning 1 of my aftermarket valve springs lets go and drops a valve into cyl4. damaging the head a little and taking a few chuks out of the piston.

01082009180.jpg


Titanium valve springs and retainers from a a ferrari 355 GT car installed and took the edges of the dents in the pistons. New 2.1mm gasket on. 1 day after a big drag racing meet, the engine starts to splutter. Compression test reveals low compression. Pulled it down to find the gasket severely blown.

03102009197.jpg


New gasket on about a month ago only to loose compression in all cyls after 200kms.

So I got the shits and it now has a std 4efte in it with my turbo running 170hp so i could continue to circuit race. Been trouble free for quite a while now

ahh harry, you engine spec was epic, so what spring's was you running that broke up?
what turbo you running on the new engine?
you still using the manifolds?

Did you ever work out why it was torching gaskets? First one could probably be explained by a rooted injector causing a single cylinder lean out, not too sure on the issues you had down the line.. what sort of fuel pump were you running?

Were you using OEM or aftermarket head gaskets? I've heard (and seen) some pretty stunning differences in quality between OEM toyota and 'reputable' aftermarket brand names around Australasia

Stuart - If I were you I'd get your injectors checked out for peace of mind, a piston doesn't just go on its own under normal conditions without some bad fuel (low octane), a lean condition (injector leaking/intermittant connection at the plug/low fuel pressure etc) or possibly getting very hot.

Cheers for the posts everybody

Detonation blew out the gasket both times. First time was std head bolts where as last time we were running close to 330hp. At the drags it ran 127mph and 11.5 with an extra 100kgs in the car from when it ran the 11.2 at 5mph less. Nitrous pressures reacts to temperature. More heat, more pressure = moer gas and more risk of leaning out. Also running mixed fuel. Was tuned on the edge but there was too many variables to run consistant. A swift here has run the same gasket with over 40psi with no problems. It is o ringed though, which cyl spacing doesnt really allow for on a starlet. Injextors are fine. Running a walbro 255 in tank and a bosch 044 external pump.

Gaz - The springs were second hand out of another race car. Im betting it was fatigue that killed that one spring as I know 4a's running the same springs to 10k rpm. I changed to titanium just in case though. Im running a custom GT28 turbo now at 28psi, same manifolds

I finally solved my lost compression issue too. The locating pin on the cam gear snapped allowing the cam to rotate indipendantly. Checking the timing, everything lined up perfect as its driven off the belt, crank. Wasnt till I pulled it down that it was noticed. Will be back in the car soon, should be fun hitting the circuit again with an extra 100hp :drive:

With this in mind...

Failure #1: With the stock 5E-FHE, did 3 trackdays in the span of 3 months, barely checking the oil level, then on a trip to Manchester I noticed the oil warning light come on...on the way there. Didn't have any money to buy oil for the 180mi journey back. Ended up seizing the oil control rings on most pistons and damaged piston 4 main or rod bearings

Failure #2: When the above engine was rebuilt, the garage messed up and had a tear in the knock sensor wire - had to drive around with the full knock detection mode for a while. In an attempt to fix this, I snapped off what I thought was the knock sensor (was Oil Pressure sensor), started car, oil went everywhere.

Failure #3: The above was fixed again, and an oil cooler was installed...in December...whilst still running mineral oil fro the above rebuild, and all of this, with no oil thermostat. Noticed that the car was building no oil pressure for at least 10mi or so everytime I started the car. In about 2 months this finally took its toll; result? Main bearing 3 WELDED itself to the crankshaft. This happened on the side of an A-Road just after we had lots of snow and I had no warm clothes...almost froze, waiting to be picked up by friends.

Failure #4: Pending...(burning 1l of oil per 150mi or so, suspected broken ringland)

car-96 tercel
engine- ep82 4efte
turbo-ct-9
ecu-stock
boost-1bar
fueling-stock
failure#1- switched from running royal purple to conventional valvoline due to a leak and not wanting to leak $7 per quart royal purple. 3 days later pulling the car into the chop for a random inspection at work and noticed a slight tap in the oil pan. drove it home and by the time i got it home had a badly spun #4 rod bearing.
Failure#2 same car 3 months after the rebuild, low oil pressure worn bearing in the ct9 with lots of shaft play, missing blades, burning oil.
Failure#3 same car replaced turbo with a used ct9 and carcked the wastegate and blew the oil seals in the turbo.
Failure#4 sold the car, new owner spun 1 rod bearing, and cracked 1 piston which i will attribute to using cheap ebay pistons and rings.

Car 92 toyota paseo
engine-ep82 4efte
turbo- hks gt2835r
boost- 10psi
ecu-emanage blue, tuned for 5psi
fueling- walbro 255, 440cc injectors, rrfpr

Failure #1 racing a ninja 600 in 3rd gear, about 75mph or so and ringlands on 1,2, and 4 gave way. lesson learned be patient and get it tuned before racing.

Same car now tuned for 15psi and running 15psi
Failure#1&2. driving on the interstate, ran low on oil spun #3 rod bearing, pulled into a gas station, got her up on a jack, pulled oil pan off, put new bearing in, put it back together, got back on the interstate, made it another 10 miles or so and same thing. got it towed home.
I'll get pics up later, its late and i'm tired.

Thought id share some pics of an engine im working on just now. This is what you get when you mix shite oil and trackdays :haha::haha:

Please note: This is NOT my engine, just one im rebuilding.

Pic on the bottom.

Haha awesome, my old engine. That took quite a beating. First time on track aswell and it shat itself big time. Engine went, turbo shit itself, manifold cracked, decat cracked and exhaust snapped.

Worked out to be quite an expensive trackday.
