totally stumped!

^ spot on.

one thing that's annoying me is that when i was putting the IM back on, i knocked the knock sensor. i fixed it up as best i can, but the clip on the sensor broke. i glued the clip back on, dont even know if it was the right way or not (does it matter?), and i think it's ok. i guess that's something else to replace if it gets to that

What was the motivation TP? Did you build this hybrid as an experiment or out of necessity? Btw, glad that it is finally sorted out. I'm curious because I have a '93 L with an ea82 spfi, 3spd pb ( id never fix this car to drive due to the trans, never another subi auto ) thats low miles, and an extra ea82T top end....i wonder

twilightprotege · Post by **twilightprotege** » Fri Feb 26, 2010 2:31 pm

kind of experiment, kind of necessity lol

i had the parts, i needed a running car. i was going to do it anyway, a badly dying ea82t neded to be swapped

initially i was going to do it so i'd have an engine that'll last me to next year when i was going to EJ20T the car, but now i'm not sure if i'm going to do that, or selll the car and get a forester

That's awesome mate! Glad its all come together so quickly. I hear you ask why I said so quickly... When I converted to MPFI - yes I did that too, before I found out about this place and the potential of having an EJ in there - anyway, the MPFI would only ever run on two cylinders at once, ran like crap, would idle badly and still move the car! It turned out that, after three months of trying everything, we'd read the instructions of the cam belt install wrong so we had BOTH cams doing the same thing at the same time... Not cool.

I was

when i got it going properly! Hope you're the same for some time

Cheers

news. went for a big drive today, 4wding and all, prob some 250km's i guess

car went great. checked the coolant long after we got home - hasnt moved a bit. checked the oil, no change at all. yay!

car did start to get a bit hot over some of the hard 4wd tracks, up to about half gauge, so we just stopped for a while and let it have a rest, then it was all ok again. only had to do that twice i think. mind you it was really hard terrain. steep uphill, very rocky and quite a few ruts. fair bit of clay, and with the rain today it was quite slippery at times, but the car just loved it.

the only thing that was a little of concern was the occasional slight splutter under WOT acceleration. i read on usmb that it could be fuel injector related so yesterday i put in some injector cleaner. nothing has changed just yet.

something that was strange is that the fuel line before the fuel filter while the car was running felt like it was pulsing. shouldnt be a fuel pump issue as it's a new walbro pump, so maybe the regulator is on the way out? could accound for the slight spluttering...

also, after we stopped it sounded like the fuel tank was gurgling - could it be an issue with that fuel seperator thingie? thoughts?

also, the car sounded like it was pinging at WOT and higher rpm's. it would only do it every now and then (i stopped testing after i heard it twice), but it wasnt every rev up. i thought it was probably just something rattling (wouldnt suprise me) but not sure.

well that's my story for tonight

STILL GREAT TO HEAR. Try wind timing back a tad. The anti knock should pull it back as much as it can, and give it as much as it can take.

I have seen a mechanical fuel injection (LUCAS) pressure reg stuffed inside cause pressure probs at 50 psi so it let the pressure of on the return line wacking the rubber hose like a dog tail wag , wack , wack against rear guard tub, A simple O ring fixed the reg

twilightprotege · Post by **twilightprotege** » Sun Feb 28, 2010 10:12 am

that's what i'm not sure about - if the anti knock is doing it's job because i'm not sure if the knock sensor is ok or not since i broke it.

might just get a new fpr - one with a (sik) gauge.

any thoughts on that fuel tank (area) gurgling?

Dunno - but I hear my fuel tank gurgling after engine shutdown when I've got a full tank or near enough to it. Once the level of the tank drops I don't hear it.

The other thing is that I don't stop filling when the filler handle clicks off - I pull it out and fill to the brim...

My L has the EFI tank fitted with larger (another standard fuel in line) return line to the tank, so its basically at MPFI spec anyway...

I don't worry about it but I did wonder what it was at first.

Its the vapour catcher that sits behind the drivers side rear wheel well.

It is said to fill to first click, otherwise you may drown charcoal cannister

twilightprotege · Post by **twilightprotege** » Mon Mar 01, 2010 1:58 pm

well at least it's nothing to worry about. i only noticed the gurgling once, and that was after a fair bit of 1st gear driving up a steep track. the tank would have been about 2/3 full at that stage.

car still going well appart from the few slight surges. definately thinking fuel pressure related

twilightprotege · Post by **twilightprotege** » Tue Mar 02, 2010 12:11 pm

on the slight surging issues - at times it's worse than others.

but i have a possible cause.

i noticed while driving along today with the check engine light on (as it always is), when the car started to splutter a little, the light for the CEL was dimming a little.

so now i'm thinking the alternator (which was from the MPFI engine) is a little iffy. the changes in the voltage it's putting out is causing the spark to maybe not fire every time. or the fuel injectors arent opening as quickly as they should (ie from lower voltage) or the fuel pump is slowing down a little and thus making the fuel pressure not as great.

i cant work on the car right now - my 2nd child is being born tonight so i kinda need the rest lol - but when alternators have played up for others, is this the sort of thing that happens???

Does this ring a bell with you steptoe? I'm sure it was you that had a dodgy valve spring or two that caused a surging issue. I know my MPFI had the same thing, sometimes it was there, sometimes it was not and other times it was really bad...

My alternator died when I had the carbie motor in. I can't see it stuffing the ECU around until the battery started to die.

And congraduations! It's the same over here, a mate finally had his little boy pop this morning...

Go get some sleep so you can think straight for your subi

thanks guys

odd thing this morning with the car too. i have been driving it a fair bit, but i hadnt driven it since monday night. battery was completely dead. not sure if its related to this or if it's related to my headlight wtf, but i certainly have things to work out. not sure about the slight surge being a dodgy valve spring - the engine has awesome compression and the surges appear to go away the higher the rpm - as strange as that sounds

steptoe · Post by **steptoe** » Thu Mar 04, 2010 10:11 pm

I coul not describe my weak as a marshmallow valve spring symptom as a surge. It was more a miss that would occur once auto gearshift was happening, or back off down slight incline in first, come to a stop let it settle itself as the HVLA lost its max pressure and it would be right again. The surge or spike I got from a crapped out corroded fusible link that blew anything powered up at the time would be more like it. It had early suymptoms that caused me to renew coil first, then came on with the big surge or spike that phuggered things. Check yer FL's for integrity

Weak valve spring did not show up on comp test

BTW - what cranking pressure are you getting ?? 130 is the norm for a good EA82T at 7.7:1
