Help, whilst driving back from Southampton to my home in the Highalnds of Scotland (Helmsdale) yesterday, i had a complete engine failure. Doing 65 on the A9 when the revs went up to about 4000 and total loss of power. Thinking the cam belt had gone i switched from drive to N and the engine stalled. I costed to the safty of the layby and tried to restart but whilst she turned over no problem it sounded like there was a man inside with a big hammer trying to get out. I think the crank is snapped and will strip engine tomorrow to have a closer look. Has anyone else got any ideas. And has anyone else made this repair before. Please email me back.
Best wishes and safe driving.
Matthew

Sounds like crank pulley/ cambelt/ head. If the belt's intact, line up the timing marks and check'em before you go any farther.
thinks
Although if it suddenly accelerated (ran away) beforehand, you're talking about oil ingestion- possibly from failed turbo or broken up piston, in which case you'd be looking at bent rods etc...

Matthew, in addition to David's helpful comments, could there have been a transmission fault, ie, a failure in the drive train which allowed the high engine revs, leading to, possibly, a cambelt or other engine component failure or, did the vehicle speed increase with the high revs?
I know, in situations like this, it is difficult to remember what exactly happened but it would be worth checking before expensive engine repairs/replacement are carried out

There was no sudden increase in speed just revs, but no more than 4000rpm, and the cambelt is ok, all pulleys ok and belts ok. Can turn the crack pulley a few degres in each direction and hear a matalic knocking inside engine.

well, the revving up would point to a transmission problem all right. Likelyhood is you'll have to pull the head or perhaps the sump to see what's happening. But there is also a chance of problems in the autobox...

Thanks David, Have now removed head and have cranked the drive shaft round a few degrees, the front three pistons move but the forth piston at the rear of the engine is stuck fast with no movement. Looks like broken crank shaft between 3 and four piston. Now stripping down further to find crank. My what a lot of bolts and stuff in here, sure if i only put half of it back it will do another 5 mph. Hmmm food for thought.
Matthew ;-)

never heard of this happening before. is this a "bad luck" problem, or something with 2ct engine?
- (#11953) eddie arrowsmith, 6 Jul 04 16:17
It could be that you have had a partial seizure on the rear cylinder which has resulted in a failed big end assembly. It's worth checking that the starter ring turns that few degrees, in line with 1,2 & 3 pistons.

I'd be VERY surprised if the crank has in fact broken, and if indeed it has would wonder if something else (seized bigend, broken up piston jamming conrod) actually caused it.
No.4 gets the hottest, and it was no.4 piston that cracked on mine. My guess is that you'll find the piston sheared in half accross the smallend, the top half seized in the bore.
Gotta say tho. You're pretty indignant about the broken crank theory. Know something we don't?

Thank you everyone who has so far added their comments and advice. Well digging down again tonight to see what we find. I hope you are right David, keeping my fingers crossed.

Engine out tonight and sitting on my front drive, tope the bottom of and guess what, the crack is broken on the end of the web between 4 and 3. No other damge to be seen, shells ok, conrods ok piston ok and removed undamaged. Thank god i had the quick thinking to pop her into N the second i though something was wrong, a lesson to us all..
Well now to try a source a new crank, shells, head bolts, gaskets and crank seals, which were leaking at the gearbos end, this i fear is a common problem reading other posts about engine oil leaks.
Any help on where to gets parts would be a great help. Once again thank you all and god bless this site.

How in God's name did you do that? The 2CT bottom end is pretty bulletproof...
Ah well, another one for the archives. Hope you get sorted OK.

David,
I know, its mad eh. There must have been a fault in the casting that has sat there for a while just waiting to happen, and me with my luck it had to happen on one of my trips back from Southampton. Thank God the five kids and wife were not with me, they are still stuck in Southampton. I have like so many of you invested so much money into my Ace that i can not afford to let her go, and i do love her the bitch that she is. Clever of Toyota to make an engine that costs so much to repair that once you have you can not afford to throw it away..

"Any help on where to gets parts would be a great
help."
Matthew. I have a spare 2CT crankshaft,with virtually unmarked journals, together with the full set of shells which it ran in before a no 3 piston failure. Also, the rear casting with an intact seal. Your vehicle is a Liteace and my items come from a Townace but, if yours is a 2CT engine, the crankshafts should be identical. If you cannot source your bits from anywhere else, you are welcome to try these.

John Davis..
John YES PLEASE. Would you like to email me at mattymyatt@aol.com so we can exchange addresses and such. How much would you be looking for. Very many thanks.
Matthew.
