And yes I know its a touch loud it goes in to get the exhaust tomorrow morning.

its first run on the tracks will be this weekend!

this is the truck its in.

[PJ.zook]

Good work mate, its bloody satisfying when you get a conversion running for the first time!

[built4thrashing]

hope it is more reliable than PJ's. Fixed that starter yet?

and that overflow bottle?

The 4age motor is great. You'll love driving the thing. post some driving vids

[v840]

Glad to see you got it all sorted mate. Looks killer.

[thehanko]

erm...

took it into get the exhaust done and... it wouldnt start.

had spark at the leads, injector pulse and fuel but nothing except a weird whoooping sound out the extractors every now and again.

cleaned plugs and got it running on just cylinder 1.

fiddled with mechanical timing but it got no better.

now looking into a compression check first thing tomorrow morning... fark. hope its ok, no cash left for a rebuild.

fingers crossed its just a crappy spark plug / timing adjustment.

been reading up about setting the computer timing ort something which i can only hope sorts it out.

really really want it ready by the weekend for a trip!

[dank]

mate if its all plugged in and wired properly the ecu does everything for you. I don't know who told you that you could "set" the ecu timing. Sounds like crap to me.

Check all of your earths, has it got oil:?: dumb question but thought I'd ask. i know in the keenness to get things running sometimes we overlook certain things. is the fuel pump priming? no kinks in your fuel sender and return lines?

Did you change the timing belt? are the timing marks on the intake and exhaust cam pulleys lining up with the crank pulley marks? have you got a decent battery in there? all your fuses in good nick? start with the simple things...then work into the harder things good luck...i wanna see some vids of this thing!

yeah i want it to be ready for our trip this weekend.

I'm hoping against hope its just crappo spark plugs, will no shortly as a new set are going in, as we pulled them out and buffed them and it then ran again although only on 1 cylinder.

but ive heard they are fairly well known for jumping teeth on the timing belt, we havent touched the timing belt at all but thats not to say its correct. I had wondered if the exhaust cam was out which was why it was firing out the exhaust a bit - but then again if it was doing this i doubt it would have enough compression to run on a single cylinder.

Ive checked:
all fused
all relays
fuel (both at pump and that the sparkplugs were wet with fuel)
injector pulse.
spark - but with a spare plug, so we have only tested it as far as to the end of the leads.
timing was checked by the auto elecy last week, and re checked by this mechanic when it wouldnt start.
oil is fine.
not losing water.

fingers crossed ill get a call saying yeah mate all ready to go...

no compressioin on cylinder 2. suspected bent valve

[v840]

Ouch!

[Guy]

The hard bit (the conversion itself) has been done .. So swapping in another motor while very disheartening is actually pretty easy .. or you could just crack the poops with it an sell it for nearly nothing ... If you are taking the later option .. I have about $22 in change a skippy badge and some pocket fluff and can be there today with a car trailer to pick it up.

no compressioin on cylinder 2. suspected bent valve

how do you bend a valve in a non-interference engine?

dont even know what that means

any way we are part way through taking the head off, 1 of the exhaust valves is stuck open on cylinder 2 hence no compression. we confirmed this by taking the rocker cover off for inspection.

head goes into a engine reco place tomorrow, he has said it will be sorted by midday for bugger all $$$ then fit it tomorrow night ready for the weekend.

nothing like a few all nighters

IT WILL BE SORTED! even if it kills me

[weaves]

non interference engine means an engine where the piston has groves ground into the top of them so that the valve cannot hit the top of the piston, helps prevent catastrophic implosions when you snap a timing belt.

And it was a serious question, i am unsure how you can actually bend a valve with a non interference engine.


oh and i hope you have some spare axles with you, i imagine that engine at full noise is going to break something.

I found one reference to bending a valve in an 4age by having the shim come out of the top of the bucket (not familiar with the engine myself so make of it what you want).

Also couldn't any of these cause it to become an interference engine;

excessive valve lift, valve reliefs not cut deeply enough into pistons, wrong pistons, not enough deck height, heads milled too much

Also reported is;

not nesecerily a stuck valve but a stuck bucket. Seen it a lot on older 4age's the buckets that hold the shim adjusters get a spot that sticks, and it sticks untill it warms up and the metal expands.

for my money i would have said that this is more likely

[weaves]

Wow that inlet valve is farked... my guess is a burnt out valve aswell.

any news hanko? is she running and what was the diagnosis?

weaves

[rogerworkman]

thats a exhaust valve

[thehanko]

so,we ripped a rocker cover off to confirm a stuck exhaust valve on #2.

decided we could have the head off, fixed and back on in 24 hours...

it took us 30 all in all.

And it lives again - by lives i mean flies!

by the way a cam cap bolt had come out and been crushed into the head by the cam and bent some metal over a valve holding it open.

but like any good story there is a but.

we took it out today to camp on stockton for my bucks night. parked on top of a dune and... nothing.

no spark.

we got as far from home as possible.

any newy crew who know their electronics... or has a coil for even multimeter to test the coil. id happily share some beer.

[thehanko]

So we woke up sinday morning to hear the little corrrolla engine revving through the dunes to wards us.

in day light phil got it running in about 5 min.

We had a few more dramas throught out the weekend and are sorting out little glitches here and there. looks like the alternator on that engine will not keep up with lights etc.

But we had a great time out on the dunes, Ill post some pics later.
